Chapter 454 The Principle of Telephone Conversation
"Pig skin?"
Qian Linjue frowned. He really couldn't imagine how the pigskin was made into a foaming state like hot rice skin. Is it really fried with hot sand like hot rice skin?Or fried?
Ok……
He was frowning and thinking, but Qian Fei'er had already given the answer with a light smile.
"These pigskins will foam when they are deep-fried. After puffing, they are full of small pores and air bubbles, which can absorb the taste and taste of other substances very well, just like eggplant."
As Qian Fei'er said, she also picked up one and put it in her mouth.
She bit it lightly, and the large amount of juice absorbed in the pigskin burst out, splashing all over the mouth, bringing a strong aroma of garlic and pork, accompanied by the spicy taste of dried chili, which was very rich in taste.
"Hmm~"
Qian Fei'er closed her eyes and enjoyed it for a while, then opened them again, lowered her head, and took a mouthful of rice.
The rice has just been steamed, with thick white heat, very fragrant.
Qian Fei'er ate it, and just happened to eat the sweet taro pieces in it.
Immediately, the aroma of dry fragrant taro mixed with rice made her extremely satisfied, even a little mesmerized.
She had a great appetite, and stretched out her hand again, and put a large chopstick on the dining table to fry bacon with garlic sprouts.
As she held her hand, she greeted her cousin, Qian Linjue.
"Lin Jue, the skin of today's bacon has been separated, try it."
"Really?"
Qian Linjue replied, stretched out her chopsticks, and added another piece.
The bacon has been fried with garlic sprouts and dried chilies, and the fat on it is much less. The thin part is dark red, and the fat part is still a bit translucent. There is no pig skin on it.
After looking at it, Qian Linjue tried to put it in her mouth and took a bite.
The fat part of the bacon is a little bit elastic, which may be the reason why it absorbed a little water from the garlic when it was fried. After biting it, there is no oil bursting on the wall of the mouth, and the aroma is not as strong as that of dry steaming.
However, although the aroma of dry-steamed pork is missing, the inside is not so salty, and it also comes with a strong garlic and spicy taste, which has a unique flavor.
Qian Linjue was very satisfied, ate it, and nodded.
Immediately, he picked up another pair of chopsticks, this time, he picked up a large chopstick of garlic sprouts and a garlic granule.
The surface of the garlic sprouts and garlic granules is shiny, indicating that they are full of bacon fat.
Qian Linjue put the garlic sprouts in her mouth and took a bite.
"Whizzing……"
The garlic sprouts are very crisp and have a strong pork aroma. The surface is smooth and oily, very delicious.
He took a mouthful of rice and put the garlic in his mouth.
The garlic grains are a little hot at the entrance, and the taste is a little flat and soft. When you eat it, it will emit a full of garlic fragrance. The strong taste goes down from the mouth, like a dive bomber, straight to the stomach, and like a jet rocket. , straight to the forehead.
Very top!
After taking one bite, Qian Linjue felt that garlic was everywhere around her body. As far as the eye could see, there were fields where garlic seedlings were planted, and even the air smelled of garlic!
The average person may find it hard to accept such a taste, but Qian Linjue is different.
He likes it very much!
After eating one, he specially picked a few, mixed them with bacon, and ate them together...
After a while, when everyone finished their dinner, the maid took away the tableware, and everyone stayed in the front hall of the main hall of Qianfei'er Xuelin Palace.
The reason why I still stay here is of course because of the kotatsu.
This thing has an irresistible appeal to people in winter, especially when it is still snowing outside.
Qian Fei'er didn't care about this. Although she often thinks quietly by herself, the lively atmosphere is not bad. She can chat with each other, and sometimes she can get inspiration and suggestions from other people's words.
So, what should we talk about?Um……
Qian Fei'er thought for a while, glanced at the crowd, and smiled lightly.
"Everyone, say, let's create a phone, shall we? In this way, no matter how far apart we are, we can talk to each other and hear each other's voices. Anytime, anywhere, it's like returning home to meet family members."
Beside the quilt, Ling Lu with a dull hair on her head raised her hands excitedly.
"Okay, okay! The phone is very convenient to use, and you can chat with Linjue anytime, anywhere!"
After she finished speaking excitedly, her eyes were full of little stars, and she had already started to imagine how she would talk to Qian Linjue in the future.
Everyone beside the kotatsu couldn't help smiling, while Qian Linjue looked at Ling Lu with a gentle face, put her right hand around her waist, and leaned slightly towards her.
Any man will feel satisfied from the bottom of his heart when he hears the girl he likes sincerely wants to meet him and hear his own voice, and Qian Linjue is no exception.
On the other side, Zi Jin with twin ponytails on her head glanced at Ling Lu and sneered.
"Tch, how can it be that simple? Do you think that inventing the telephone is the same as drinking water? Come when you want?!"
After finishing speaking, Zijin turned her head with a look of contempt.
Ling Lu was so angry that she was about to refute, but at this moment, the noble and elegant Qian Nawei, who was wearing a luxurious golden dress, suddenly spoke.
She glanced at Zijin and smiled.
"Zijin, it's not very difficult to invent a telephone, you just need to know the principle. First of all, the wired telephone, the sound is transmitted by electric current, that is to say, the sound signal is transformed into an electrical signal.
We know that sound is produced by the vibration of objects. Therefore, the sound coming out of the phone must also be the vibration of the vibrator on the receiver.
So why does the vibration occur?Let's ignore the receiver and look at the microphone first. "
While talking, Qian Nawei took out a piece of paper and a pen, and drew a picture of a wired phone.
She pointed to the microphone and wrote the words "vibration and sound".
"We know that when speaking, the vibrator on the microphone must vibrate, otherwise it is impossible to transmit the sound. Then, the vibrator is connected to the current, and the vibration must change the current, so that the sound signal is converted into electricity. The signal propagates out.
So, what exactly is the change?Suppose, is the resistance change. "
While talking, Qian Nawei drew a hanging electric fan.
She pointed to the electric fan and continued to explain.
"We know that a change in resistance will cause a change in the kinetic energy of an object. Just like a fan, switching the resistance will generate different wind power. At this time, we will look back at the earpiece. If the resistance is higher, the sound will be relatively smaller. Resistance When it becomes smaller, the sound increases relatively.
At this time, if the continuous resistance of different sizes on the microphone side changes, a continuous current of different sizes will be generated, and the sound of continuous changes in sizes can be heard on the receiver side, thus forming a word or a sentence. .
Vibration is the key to change. When we speak, the microphone vibrates. The vibrator is connected to a resistor switch. The sound signal was successfully converted into an electrical signal. "
"Crack, crack, crack...!"
Suddenly thunderous applause erupted in the room, and everyone was very surprised. Unexpectedly, Qian Nawei figured out the principle of wired telephone calls!
On the side of the kotatsu, Qian Nawei lifted her skirt slightly, nodded slightly, bowed slightly, and smiled to express her gratitude for the applause of everyone.
Sitting next to Qian Nawei was Qian Fei'er with squinting eyes. She looked at her cousin appreciatively and nodded slightly.
Just before that, Qian Fei'er also thought about the production of wired phones, and she brought it up today because she wanted to hear the different opinions from everyone, and at the same time, to see if anyone had the same thinking as her.
Qian Fei'er once thought that the first person who thought the same as her should be Qian Nawei, who had the most delicate thoughts, but unexpectedly, it was so.
It seems that when you have no ideas in the future, you can talk to Nawei about it.
Qian Feier thought to herself.
Then, she chatted with her cousins, Hua Ning, Ling Lu and others for a while, until after nine o'clock in the evening, Qian Linjue and the others left.
Qian Linjue and Ling Lu went outside the main hall of Xuelin Palace. At this time, the snow had been falling for a long time, and the ground was covered with a thick layer, and the thickness continued to increase.
The thick snow-white cotton covered the ground, and Hua Ning and the others walked away while talking and laughing, and there was a creaking sound when they stepped on it.
Linglu excitedly rushed to the yard, took a large handful of snowflakes and threw them into the sky, looked at Qian Linjue, and said excitedly: "Linjue, let's build a snowman!"
Qian Linjue stroked her forehead helplessly.
Just want to build a snowman?
He shook his head slightly, and said softly, "It's very late, I'll pile it up for you tomorrow, come here quickly, don't get frostbite."
While talking, he walked down the steps and pulled Linglu's small hands into his pockets.
Because Qian Linjue's martial soul has a high-temperature attribute, Linglu can feel a burst of warmth even through her clothes.
It's like a real stove!
She showed a happy expression, and put her head into Qian Linjue's arms, leaning her pretty face on Qian Linjue's chest as much as possible.
Qian Linjue did not refuse, and hugged the cute girl with her backhand.
While hugging Ling Lu, he also turned his head to look at a girl with two ponytails, Zi Jin, who was about to leave the courtyard of Xuelin Palace not far away.
Facing Zijin, his tone was no longer so gentle, but instead became haughty and arrogant.
"Hey, Zijin, I ordered you to stay in my room to rest tonight, and you are not allowed to go back, did you hear me?"
At the end, Qian Linjue seemed to show a little anger on her face, but in fact, the corners of her mouth kept hooking up after she finished speaking, evoking a haughty look.
When Zijin heard this, she put her hands on her waist and turned around, with the same haughty expression on her face, no less haughty than Qian Linjue.
"Do you want to be with Miss Ben that much? What an evil idea, but Miss Ben is not such a casual person. I won't go unless you kneel down and lick my feet."
