Yuan Fang's words may be a bit unashamed, but he is very confident in the thermometer, its use involves many industries, such as winemaking, smelting, medical treatment, etc., once widely used, it will play a vital role in the technological development of these industries, if the so-called industrial department can see this clearly, then this will be a great invention. Pen, fun, pavilion www. biquge。 info

Yang Xing didn't hesitate at all, shook his head decisively and said: "Don't go, boss, this is something you made, I don't want to impostor, besides, I don't have any interest in any career as an official, otherwise I would have gone to the test for fame a long time ago, boss, I will follow you, I will listen to you no matter how you decide." ”

Yuan Fang laughed and hugged Yang Xing's shoulder: "Let's go, go to Brother Mo first." ”

Yang Xing grinned: "Just go and see Wen Fang, Wen Yue and Xiao Mingjie." ”

There was nothing to say all the way, and the two came to the dart game, which is a coincidence, almost every time Yuan Fang came here, he could catch up for dinner, and this time was no exception.

At the wine table, Yang Xing and the three little guys pushed the glass and changed the cup (Yang Xing drank wine, and the three guys drank juice. The atmosphere is cheerful and warm, and the three little ghosts who usually don't eat much have changed their normal behavior today.

Xin Huilan eagerly took care of the three children, Mo Zhiyuan and Yang Xing drank, and Yuan Fang explained the use of the thermometer to Jiang Chengjia and tested it on the spot.

Jiang Chengjia couldn't put it down and played with the thermometer: "Doctor Yuan, it would be nice if this thing had a fixed temperature contrast." ”

Yuan Fang smiled and said, "The second sister-in-law is talking about the scale, right?" ”

Jiang Chengjia pondered for a moment and said: "Yes, it's the scale, Brother Yuan's knowledge is good, I can't think of such an appropriate word." ”

Yuan Fang scratched his head ashamedly: "This is not difficult, determine two points first, and the rest will be easy to do." ”

Jiang Chengjia looked at Yuan Fang and asked, "How do you determine two points?" ”

Yuan Fang first asked Mo Zhiyuan: "Brother Mo, do you have any ice cubes here?" "It's the height of summer, and ice cubes are hard to find, so only some big families have ice cellars to store ice cubes, which are used to make sour plum soup and other relieving the heat in summer.

Mo Zhiyuan frowned and reminded: "I don't have this, but that Wang Fugui's family should have it." Yuan Fang patted his head: "Then it's troublesome for Big Brother Mo to send someone to the medical hall to find Steward Wang to get it back." Mo Zhiyuan ordered people to do so.

Yuan Fang looked at Jiang Chengjia and explained: "What about this scale, one is zero and the other is 100 points, which means zero degree and 100 degrees. ”

Then, Yuan Fang asked people to make a charcoal stove, boiled a small half pot of water, waited for the water to boil, and inserted the bottom end of the thermometer, which is the part that holds the mercury, into the boiling water: "Under a standard atmospheric pressure, the temperature of boiling water is 100 degrees, and when the mercury in it stabilizes, that scale is 100 degrees." The height of the mercury in the thermometer did not change, Yuan Fang took out the thermometer and put it on the table, and gently scratched the position of the mercury height with an acute angle similar to a strip of sand, and suddenly, a clear scratch appeared on the glass tube.

Yuan Fang asked for cinnabar, carefully applied it to the scratches, and showed it to everyone: "This height represents one hundred degrees, that is, the temperature of boiling water." ”

Jiang Chengjia's face was full of doubts: "What is the standard atmospheric pressure?" Is there anything that is not standard? Yuan Fang was stunned, he didn't know this, he only knew that the atmospheric pressure in the plain area was almost a standard atmospheric pressure, and the altitude would decrease at high altitudes, and the others would not know.

Just when Yuan Fang was worried about how to explain this, the person who went to fetch the ice came back, put the ice cube into the prepared water basin on the ground, poured a few glasses of wine and went out.

At this time, in addition to the three little children and Jiang Chengjia, Mo Zhiyuan, Yang Xing and Qin Huilan also each took a thermometer and inserted it into the boiling water, and carved the scale by hand.

Yuan Fang underestimated the woman's curiosity, Jiang Chengjia stubbornly pestered the question just now, Yuan Fang had no choice but to say the little common sense he knew, for example, the boiling water at standard atmospheric pressure is 100 degrees, the higher the altitude, the lower the air pressure, the lower the temperature of the boiling water, as for the lower the altitude, the higher the temperature of the boiling water, Yuan Fang is not clear.

Waiting for the time for the ice to melt, Yang Xing and the three little children played with the little bees they had played with before, and suddenly, the sounds of humm-ah-ah in the room came and went, and the happy laughter was endless.

Yuan Fang looked at Mo Zhiyuan with a wicked smile: "Brother Mo, why don't we have fun too?" ”

Mo Zhiyuan was stunned, and then laughed and said: "Cheng, but it's okay to play, you can't be like them, let's really fight, the kind that smokes hard, how about it?" ”

Yuan Fang was stunned for a moment, and shook his head again and again: "Don't do it, if you give me a little bit of strength with your thick arm, my little life will be gone." Mo Zhiyuan smiled proudly, he smiled proudly.

Yuan Fang was very unhappy, glanced at Xin Huilan, who was covering her mouth and chuckling, and thought about it: "Brother Mo, otherwise, if I lose, let my sister-in-law fight, and if you lose, let my sister-in-law fight, how about it, it's fair now, right?" Mo Zhiyuan looked at Xin Huilan, Xin Huilan nodded vigorously, she was also a restless woman.

Mo Zhiyuan nodded in agreement, rolled up his sleeves and was about to start. Yuan Fang raised his hand and said, "Wait, if it's a tie, you can't put on a show like them, right?" ”

Mo Zhiyuan's eyes widened: "You kid won't do this, and you want your sister-in-law to do it for you, right?" ”

Yuan Fang stumbled when he heard this, fell to the ground with his buttocks, and rubbed his buttocks for a long time to stand up and said, "Brother Mo, you are ruthless enough, I admit that I will not succeed." As he spoke, he took his glass and drank it down.

Mo Zhiyuan was not much better than Yuan Fang, and the moment he said that, Xin Huilan blushed with shame, and her little hand twisted around his waist.

In the midst of laughter, the ice cube had melted, and Yuan Fang picked up the previous thermometer and inserted it into it and said: "The temperature of the liquid mixed with ice water dissolved in the standard atmospheric pressure is zero degrees. ”

According to the way just now, a scale was carved on the thermometer, and then, Yuan Fang introduced: "With these two points, it is easy to do, divide it into equal 100 parts, which represents the relative scale of 100 degrees, although there is an error, but it will not be too big, and the second sister-in-law will be able to control the temperature of the wine in the future." ”

Mo Zhiyuan stared at the palm-sized thermometer, and the distance between the two points, and said in embarrassment: "One hundred parts, you have to divide them evenly, it's not easy to tidy." ”

Yuan Fang smiled: "You can use paper, first cut out the same length of paper with paper, fold it in half, and then fold it in half, this is a quarter of equal parts, that is, it represents the 25 degree base system, and the rest is simple, right?" ”

Mo Zhiyuan's eyes lit up, and he patted the table and exclaimed, "Brother Yuan, what's your head?" Alas, don't say anything, come and drink. ”

As soon as he put down the wine glass, even the sledgehammer ran in, and when he saw Yuan Fang, he pulled and left without saying a word: "You kid is finally here, go, go and see how to assemble it, I have all the parts ready." Yuan Fang was dragged to the blacksmith furnace, Mo Zhiyuan followed curiously, and Yang Xing was naturally not far behind, and took three followers with him.

Xin Huilan looked at Jiang Chengjia: "Sister, Doctor Yuan's thermometer is really good, it should be used in the winery, right?" ”

Jiang Chengjia nodded: "I really don't know how Dr. Yuan came up with it, such a magical thing looks very simple, but why didn't I think of it." ”

Xin Huilan smiled: "This is wisdom, I think Dr. Yuan should not be an ordinary person, no matter what knowledge and mind can be compared to those of us." ”

Jiang Chengjia nodded in agreement: "Well, I think so too." ”

Xin Huilan said softly: "Sister, you said that if this thermometer is mass-produced, will it be sold well?" ”

Jiang Chengjia's eyes lit up: "It should be good, sister, what are you going to do?" ”

Xin Huilan smiled and said, "Let's wait until your winery has tried it, if there is no problem, I plan to talk to Brother Yuan to see if he has any intention of cooperating." ”

In the backyard, the blacksmith furnace, there are a lot of onlookers, these days, everyone is choked by the sledgehammer, the sound of striking iron has hardly been broken, I heard that even the sledgehammer toss the things are almost the same, all come to watch.

Even the preparation of the sledgehammer is very well done, the main frame has been assembled, the rest is the part where the bearing is installed, in the box on the ground, three types of screws, iron pads are a lot of plates, pliers and other tools are readily available, I don't know to see, I thought it was a roadside repair bicycle stall.

Yuan Fang is still familiar with bicycles, when he was in school, he rode for six years, at that time, in order to save some money to repair the car to play game consoles, he basically repaired it himself, and he knew a lot about the structure of the bicycle.

First of all, install the central shaft, clamp the bearing into the reserved hole, install the main gear wedge to fix, install the pedal, turn a few times, and there is no jamming and stagnation.

Then there is the rear axle, the rear axle is a little more complicated, bearings, circlips, flywheels, gears, and then fixed in the hole in the center of the wheel, install the gear of the chain connecting the bottom bracket and the rear axle, adjust the spacing, so that the chain is tight and will not fall off easily, and then link the frame and tighten it with screws.

Finally, the front axle, which is relatively simple, with the addition of bearings and fixed links to the frame, the overall installation of the bicycle is basically completed.

Throwing away the board in his hand, holding on to the handlebar and shaking it a few times, Yuan Fang grinned.

Seeing that it was done, Yang Xing hurriedly proposed: "Boss, didn't you say that two wheels can also walk, you give us a try." ”

Yuan Fang glanced at Yang Xing: "Try it, there are no tires yet." ”

Yang Xing was surprised and asked, "Tires?" Aren't there wheels? ”

Yuan Fang rolled his eyes and said, "You don't want me to run around on two iron rings, do you?" I'm not Nezha. As he spoke, he turned his head to look at Mo Zhiyuan, who was amazed: "Brother Mo, do you still have the rubber plate you brought back?" ”

Mo Zhiyuan nodded: "Yes, those things have basically not moved, I'll get them for you." Mo Zhiyuan also wanted to see if this strange thing could really go.

Yuan Fang reminded: "Don't be white, just the dark gray kind, one is enough." ”

After a while, Mo Zhiyuan came back, and a specially treated rubber plate was placed in front of Yuan, Yuan Fang had already removed the two wheels, and casually cut a piece of rubber with this wheel width, rolled it out of the wheel, and did not have time to dissolve and condense it, so he simply wrapped it around and installed the wheel.
