"Look, 50mm magnifying glass, f/quarter." Lin Hanlong took out the magnifying glass and handed it to Wu Nanhai. Wu Nanhai picked up the writing paper on the table and looked at it with the magnifying glass.
"Well, you did a good job. It's very clear." Wu Nanhai clicked his tongue and touched the handle of the magnifying glass with his hand. "If it weren't for the wooden handle, I would have thought we brought it." []
"Most high-end magnifying glasses are made of natural materials, and wood is just one of them."
Wu Nanhai put down his magnifying glass and nodded. "Okay, no problem at all. The more the better in our agricultural department for this kind of thing." He turned back to greet the staff of naturalized residents, "Go, collect the bill of lading and let them go.
Let’s go through the delivery procedures.”
"Very good, this will clear up both sides."
"By the way, that sugar meter I mentioned last time, you said it's ready?" Wu Nanhai's voice became solemn as he said this, and avoidance was the real purpose of his visit.
"Oh, that." Lin Hanlong took out a box from the drawer as if nothing had happened. "I made one. Take a look."
The sugar meter is a rapid detection instrument that uses optical principles. It is specially used to quickly measure the concentration or refractive index of sugar-containing solutions and other non-sugar solutions. It is important in sugar production, food, beverage and other industrial and agricultural production fields.
Function. In addition to measuring sugar content, it can also be used to measure the concentration of various sauce products such as soy sauce and ketchup. In agricultural production, it is suitable for determining the accurate harvesting period of fruits and sugar crops and measuring sweetness.
Hierarchical classification.
The principle is that refraction occurs when light enters from one medium to another, and the ratio of the sine of the incident angle is constant. This ratio is called the refractive index. The content of soluble solids in fruit and vegetable juices and the refractive index
It is proportional to the same temperature and pressure. By measuring the refractive index of the fruit and vegetable juice, the concentration of the fruit and vegetable juice can be found.
The sugar meter that Wu Nanhai took out basically looked like a sugar cane with one end sharpened. The pointed end was inlaid with glass, and there were several knobs at the other end of the cylinder. Wu Nanhai picked up the sugar meter and brought it to his eyes, turning the sharp end.
With his head facing the light, he turned the knob with his fingers. He turned to Lin Hanlong, "Old Lin, I'm sorry, I want to take a look."
Lin Hanlong nodded. "Of course."
Wu Nanhai turned his head. "Chu Qing! Bring those bottles."
The bottle was filled with water and sugar water mixed in different proportions. Wu Nanhai first dropped a few drops of water on the glass, and then adjusted the knob. Lin Hanlong passed a flannel cloth to the side, and Wu Nanhai took it and wiped off the water droplets.
Then he dropped sugar water. He squinted and looked at the light for a while, then wiped off the sugar water, replaced it with a bottle, and added a few drops to see. After repeating this several times, he put down the sugar meter and exhaled.
"Old Lin, you are really good! This thing is very well made, and the sugar content measurement is very accurate." Wu Nanhai was smiling all over his face at this time. "Very good, very good. I want as much of this thing as I want. I will have someone report it later."
."
Lin Hanlong nodded. "Just sign the form and stamp it with the Agricultural Committee's seal later. This sample can be taken away now." He took out a wooden box from the drawer, opened it and handed it to Wu Nanhai.
"Matching box."
"The lenses here are mass-produced goods, no problem. But the prisms are ground by hand. For mass production, we have to wait for the surface to be ground."
"Oh, how long will it take? I plan to send a batch before the next harvesting season and teach them how to use it in advance."
"You have to ask the Navy. They are in urgent need of binoculars and they plan to install two on each ship."
"How much will it cost? Sucrose is an important source of income for us, so we can't throw it away." Wu Nanhai said anxiously. He was also made anxious by Wentong - Wentong was promoting sugarcane production combinations in Leizhou, cultivating improved varieties, and rotating prices based on quality.
It is an important link in Leizhou's sugar industry policy. Without sugar meters, the rules and regulations formulated by Wen Tong cannot be implemented in detail.
"Who says it's not?" Lin Hanlong agreed casually, but did not give any specific indication that Wu Nanhai had woken up; "I will help you tell the executive committee that optical instruments are too important and we need to increase investment."
"As long as you take action, one can stand up to three of them."
"Hahahahahahahaha..." Wu Nanhai laughed a few times and raised his hand. Chu Qing quickly opened a straw bag that she brought with her and took out a wooden box from it.
"This is a new cigar from the farm. Please try it."
"No, no, I haven't finished the limited edition you gave me last time..." Lin Hanlong became polite.
"Try something new. This time it's Li Quan's limited edition." Wu Nanhai smiled, "Try it. I asked the Jesuits to get the tobacco leaves from Macau, and the real wrappers are made from the Caribbean."
Lin Hanlong thought for a long time before he remembered who Shu Liquan was. He smiled and took the box. The box was made of a kind of precious wood and exuded a light woody fragrance. According to Wu Nanhai, the wood was imported from Southeast Asia.
The polished white wood box cover was stamped with black fonts and even had swashbuckling characters that he didn't recognize. The box also had a green sticker with the words "tax-free" from the Monopoly Bureau of the Ministry of Finance.
It looks very impressive.
In comparison, the last limited edition was just packed in cardboard. It goes without saying which one is more advanced. Lin Hanlong found that the packaging description of Li Quan's limited edition was "three pieces in", and couldn't help but secretly scold Wu Nanhai for becoming more businesslike.
Already.
"Not bad, not bad." He also said haha. Wu Nanhai took out two more glass bottles from his pocket.
"This is fruit wine made from blueberries grown by Xue Ziliang at my place. The alcohol content is not high. You can have a drink. It's hot enough here."
"Why are you so embarrassed? You always bring things..." Lin Hanlong felt a little embarrassed. In recent months, Wu Nanhai has been sending things here and there.
"It doesn't matter. You are busy with work here and work late shifts every day. You need to supplement your nutrition." Wu Nanhai disagreed, "Isn't the farm just for serving the elders?"
Wu Nanhai said as he staggered out and walked out, still holding the box of sugar meter in his hand. His naturalized people followed him and filed out. When he was about to walk out of the workshop, he caught sight of a point with the corner of his eye.
What? He turned his head and looked at it, said ah, and then jumped out to a corner of the workshop.
"Old Lin!!!!"
Lin Hanlong rushed out and met Wu Nanhai's eyes with a faint green light. He couldn't help but secretly said: "It's broken!"
Fatty Wu tremblingly pointed at a row of curved cast iron workpieces with his fingers, and said in a trembling voice: "Show, show, microscope... you, why didn't you tell me." What he pointed at was a row of microscopes.
The mirror base is no different from that used by later generations.
Lin Hanlong smiled bitterly and said, "You didn't even ask me if I could do it. These are set by the Ministry of Health, and we need them very urgently."
Fatty Wu jumped up immediately. "I didn't ask because I thought this thing was difficult to make! Didn't it say mass production was only possible in the 19th century?"
"I used Leeuwenhoek's method, using surface tension to make aspherical lenses. It's quite easy to make." Lin Hanlong pretended to be calm and authentic, "Of course, with slight improvements, we can produce products of multiple specifications with high accuracy.
Within one percent.”
Wu Nanhai stared at Lin Hanlong for a while and laughed. "Old Lin! In the field of optics, you belong to us! You can do what others can't!"
"That's not the case, there's more"
Wu Nanhai patted Lin Hanlong's shoulder heavily: "Old Lin! You have made a great contribution to the work of our Ministry of Agriculture! I, Wu Nanhai, understand very well!" Fatty Wu patted his chest, "Don't talk nonsense.
Yes, our Ministry of Agriculture will strongly support the work of the optical factory in the future. Such an important matter should be put in a priority position for development.
Executive Committee, I’ll take care of it!”
The two laughed for a while again.
Wu Nanhai suddenly remembered something. "Old Lin, according to your habit, you must have made a few test products before mass production, right?" When he said this, the green light emitted from his eyes was enough to illuminate the entire workshop.
Except that it looked a little rough, the homemade microscope Lin Hanlong took out looked no different from later products at a glance. He pointed at the objective lens and said, "Three magnifications, 50, | 50, but the positioning mechanism is not very good.
Be careful when turning and adjust it slightly to prevent the light path from being incorrect." He pointed at the eyepiece again and said, "The eyepiece is not painted. Wipe it clean after use, otherwise sweat will corrode it."
Lin Hanlong found a piece of cloth to wrap the microscope; "There is no box, so you can just take it. This is a trial product. There are still many minor problems. Please pay attention to it when using it. If you have any questions, tell me."
"It's easy to say! It's easy to say!" Wu Nanhai walked out with satisfaction, holding the sugar meter in his left hand and holding the microscope tightly in his right hand.
After sending Wu Nanhai away, who looked like a prisoner leaving the village, Lin Chalong asked his apprentice to get another towel to wipe his face, and quickly began to inspect the workshop for the second time. The workers' professional level was not high, even if they were experienced, they were only half-skilled.
It’s a state of understanding. A half-full bottle of vinegar is the most dangerous. Bad things happen from time to time, and it’s almost impossible to prevent.
When Lin Hanlong had patrolled the grinding machine halfway and was listening carefully to the sound of the machine, someone came to report that a Chief Qian was looking for him at the door.
Chief Qian has a strong build and obvious muscle lines. He wears the standard attire of a veteran with a short T-shirt and sunglasses. A holster is tied to his big t-shirt, and the handle of the gun with a square head is exposed. Although it is a standard attire, if you look closely,
This outfit is actually very different from others. The sunglasses are like those of Tom Cruise in Top Gun, the pure color T-shirt with a collar can actually make you look slim, and the shorts are obviously military products such as 51｜, even
The shoes are not ordinary running shoes that can be found on the market.
The visitor took off his sunglasses, revealing a pair of piercing eyes. It was Qian Shuiting, the current Speaker and leader of the House Party. "Old Qian! What wind has blown you away?" Lin Hanlong greeted him with a haha.
"I just happened to go to the machinery factory for research today. I'll come over to your place after I'm done. How are you? Have you eaten?"
Lin Hanlong shook his head. "I don't have time. I'll ask the cafeteria to send something over later."
Qian Shuiting took out a big box from the straw pocket behind him; "I have prepared some things, why don't we eat some together?"
Inside the box were two large lunch boxes preserved with ice. Lin Hanlong glanced into the box. "Sushi! Where did you get this?"
There are pieces of rice balls in the box, rolled with cabbage, etc., and covered with red fish meat. It is the Japanese sushi that will be known to the world in later generations.
Lin Hanlong asked Qian Shuiting to come into the office. There were too many things on the desk and it was difficult to clean up, so he asked someone to set up a small folding table and wipe it down to use it as a dining table. The two sat opposite each other. Lin Hanlong asked his apprentice to bring some
A bottle of kvass - it's not convenient to drink seriously during working hours.
Qian Shuiting said that when he was working in California, he also worked in a Japanese restaurant, and it was easy to make sushi. Unfortunately, there was no suitable sushi rice locally, and the taste was only marginal. Of course, there was no sushi vinegar.
However, Tianchu has brewed white vinegar, so I can use it as a substitute for the time being. Feiyun can often go fishing at sea, and has made an appointment with some fishermen to deliver good products whenever they have good ones, so the seafood and fish are still fresh. "Tianchu does have Japanese soy sauce; after all, everyone often
Eat sashimi." Qian Shuiyan opened a lunch box as he spoke. "This is fresh mustard I got from Wu Nanhai - I grind it myself, not mustard paste."
"Speaking of Wu Nanhai, he just left my place." Lin Hanlong always adhered to the view that individual happiness is not as good as everyone's happiness. He picked up Li Quan's limited edition cigar from the table, "How about one later?"
"No, you better smoke it yourself." Qian Shuiting said, "I have to be strict with myself now."
At first, Lin Hanlong thought Qian Shuiting meant to take care of his body, but later he understood: "You mean you can't take gifts from others?"
"That's what it means."
"It's just a box of cigars...Lin Hanlong doesn't think much of this kind of personal gift to attract affection. Almost everyone among the elders has a share.
Qian Shuiting shook his head; "We don't lack these circulation coupons, so it's better to buy them directly, so as not to stain the scenery. Old Wu is a very nice person, and he can't stand someone-" He probably felt that this was inappropriate, so he didn't say it
Already.
"Do you think this is the United States..." Lin Hanlong felt that since Lao Qian organized the House Party and became the Speaker, his behavior was very different from before - a bit too neurotic. Politics is indeed not something ordinary people can do.
"We're not from the United States, so we have to pay attention. It would be easier if we were in the United States." Qian Shuiting poured him a glass of kvass. "Hey, let's have a drink first."
After eating a few pieces of sushi, Qian Shuiting stared at Lin Hanlong: "Old Lin, I'm not talking about you. You're a little thinner than last month."
"Eh? I don't think so." Lin Hanlong has a great appetite, and eating cold food like sushi in hot weather suits his appetite.
Qian Shuiting picked up the chopsticks and nodded, "You're confusing right and wrong. You work all night, have meetings in the morning, and do things at the machinery factory. It's the hottest time at noon, how can you sleep well?"
?" He picked up a piece of sushi and put it in Lin Hanlong's bowl, "This is flying fish roe, very good. You should eat more. You can't sleep well, eat well and are tired. Can you not lose weight? Your body still needs it.
No more?"
“Hard work is inevitable in the early stages of a career.”
"Everyone is starting their own business, so you have to work much harder than others."
"When the optical factory has an independent power source in the fall, we won't have to work the night shift. It will be easier then."
"Let's talk about this. The steam engines from the machinery factory are being shipped out one after another. Why does your optical factory, which is close to the water, have to wait until autumn?"
This time it hit Lin Hanlong's sore spot.
"You also know that some people in the executive committee said that optics should wait until the second five-year plan, and it will not be too late to develop in the third five-year plan. What do you think?"
Lin Hanlong shook his head; "What do they know? I have so many people urging me to do this and that, but I can't do it."
"That's right! You all only understand your own one-third of an acre of land, who understands it better than the other? It's only been a few years, and you no longer listen to what the front-line veterans say."
"There is no one on the executive committee who is engaged in scientific research, not even a graduate student. He has no intuitive experience in scientific research and development."
"If this continues, it will be up to them to decide how to climb the technology tree? Isn't this the case that laymen lead experts?"
Lin Hanlong waved his hand; "Forget it, let's eat." He was really hungry, and he quickly drank most of a large box of sushi. He also drank a bottle of kvass.
Qian Shuiting watched Lin Hanlong put down the kvass bottle and said, "I think there must be a voice to speak for the front-line technical veterans."
Lin Hanlong looked at Qian Shuiting and said nothing.
"Take your optical factory as an example. Many people think that we still have a lot of inventory and there is no need to rush. But if I look at it, no matter how much inventory we bring, the categories will always be incomplete and the quantity will always be limited.
Lin Hanlong nodded in agreement. "People from all walks of life ask me for a lot of things, many of which they have never heard of before."
"Old Lin, you are so busy that you are confusing right and wrong. It is not easy for you to say something. As the speaker, speaking is my job. I feel that I have to speak for the vast number of technical veterans.
Qian Shuiting looked at Lin Hanlong sincerely, "I understand the importance of your optics. But can you give me an explanation of how far we can achieve it at this stage?"
Lin Hanlong nodded again; "I'm sorry to trouble you." He was silent for a moment, trying to organize his words.
"Optics, as far as theory and design are concerned, our time and space are very mature things." He pointed at himself, "I graduated from the optics class, and I also do optical work. I can handle design and other things."
As for process manufacturing, it’s not particularly difficult to say it’s difficult. Many enthusiasts can grind lenses by themselves. At least I won’t be worse off if I’m a professional. To put it bluntly, optical things are mainly a kind of precision machining, nothing more than
The processing volume is relatively small, and there are relatively simple ways to make accurate measurements." He looked at Qian Shuiting and paused, "I dare say that as long as I have enough resources, I will be able to achieve the results before the 20th century in a few years.
level."
Qian Shuiting made a gesture of excitement. "Old Lin, you are so awesome here! It's great!"
Lin Hanlong nodded. "Seeing is believing. Last time you said you wanted to see my place, are you free today? I was about to go on a inspection tour!"
