Chapter 454: The Principle of Telephone Conversation

"Pigskin?"

Qian Linjue raised his eyebrows, he really couldn't imagine how the pig skin was made into a foaming state like hot rice skin, is it really the same as hot rice skin, fried with hot sand? Or fried?

Well......

He frowned and was thinking, and Qian Fei'er had already chuckled and said the answer.

"These pork rinds will foam when they are fried, and after puffing, they are full of small pores and bubbles, which can absorb the flavor and absorb other substances very well, just like eggplant."

Qian Fei'er said, picking up one herself and putting it in her mouth.

When she bit it gently, a large amount of juice absorbed in the pork skin exploded, splashing all over her mouth, bringing a strong garlic and pork aroma, accompanied by the spicy taste of dried chili peppers, which was very rich.

"Hmm~"

Qian Fei'er closed her eyes and enjoyed it, then opened it again, lowered her head, and took a bite of food.

The rice has just been steamed, and it has a thick white steam, which is very fragrant.

Qian Fei'er ate it, and just ate the taro pieces in it.

Suddenly, the dry fragrant taro mixed with the aroma of rice made her extremely satisfied, and even a little intoxicated.

Her appetite was aroused, and she stretched out her hand again and put a large chopstick on the table with garlic sprouts and fried bacon.

While clipping, she greeted her cousin, Qian Linjue.

"Lin Jue, today's bacon separates the skin, you can taste it."

"Oh? Is it? ”

Qian Linjue replied, also stretched out her chopsticks, and added a piece.

The bacon has been fried with garlic sprouts and dried chili peppers, and the fat on it is much less, the lean part is dark red, and the fat part is still a little translucent, and there is no pork skin on it.

After looking at it, Qian Linjue tried to put it in her mouth and bit it.

The fat part of the bacon has a little elasticity, which may be the reason why it absorbs a little water in the garlic seedlings when it is fried with garlic seedlings.

However, although there is a lack of aroma of dry-steamed pork, it is not so salty inside, and it also has a strong garlic aroma and spicy flavor, which has a unique flavor.

Qian Linjue was very satisfied, ate it, and nodded.

Immediately, he picked up another chopstick, this time, it was a large chopstick garlic sprout, and a garlic granule.

The surface of the garlic sprouts and garlic grains are shiny, indicating that they are full of bacon fat.

Qian Linjue put the garlic sprouts in her mouth and took a bite.

"Whoosh, whoosh......"

The garlic sprouts are very crisp and have a strong pork aroma, and the surface is smooth and oily, which is very delicious.

He took a bite of his rice and put the garlic in his mouth.

The garlic is a little hot in the mouth, the taste is a little noodles, some soft, and when you eat it, it will be filled with a full garlic fragrance, and the rich flavor will go straight to the stomach like a dive bomber, and like a jet rocket, it will go straight to the brain.

Very top-notch!

Qian Linjue only took one bite, and felt that there was garlic everywhere around her body, and there were garlic seedling planting fields as far as the eye could see, and even the air was garlic-scented!

For such a taste, it may be a little difficult for ordinary people to accept, but Qianlinjue is different.

He liked it very much!

After eating one, he specially picked a few, mixed it with bacon, and ate it together......

After a period of time, everyone finished their dinner, the maid took away the utensils, and everyone stayed in the front hall of the main hall of Qianfei'er Xuelin Palace.

The reason why it is still here is, of course, because of the kotatsu.

It's an irresistible attraction for people in winter, especially when it's snowing outside.

Qian Fei'er doesn't care about this, although she often thinks quietly alone, she also has a good lively atmosphere, you can chat with each other, and sometimes get inspiration and advice from other people's words.

So, what should we talk about? Well......

Qian Fei'er thought for a moment, glanced at everyone, and said with a chuckle.

"Everyone, you say, should we create a phone? In this way, no matter how far apart you are, you can talk to each other, hear each other's voices, and feel like you are back at home and meeting your family anytime, anywhere. ”

By the hearth, Suzulu, who had a dull hair on her head, instantly raised her hands excitedly.

"Yes, yes! The phone is easy to use, and you can chat with Linjue anytime and anywhere! ”

After she finished speaking excitedly, her eyes were full of little stars, and she had already begun to reverie what it would be like to talk to each other with Qian Linjue in the future.

Everyone around the quilt couldn't help but smile, but Qian Linjue looked at Linglu with a gentle face, put her right hand around her waist, and leaned slightly to her side. Let's go slightly

Any man will feel sincerely satisfied when he hears the girl he likes sincerely say that he wants to meet him and hear his voice, and Qian Linjue is no exception.

On the other side, Zi Jin, who had a double ponytail on her head, glanced at Linglu and sneered.

"Cut, how can it be so simple? Do you invent a telephone the same as drinking water? Come as you want?! ”

After speaking, Zi Jin turned her head with a look of disdain.

Linglu was angry and was about to refute, but at this moment, Qian Nawei, who was wearing a luxurious golden dress and was noble and elegant, suddenly opened her mouth.

She glanced at Zi Jin and smiled.

"Zi Jin, the invention of the telephone is not very difficult, you only need to know the principle, first of all, the wired telephone, the sound is transmitted by the current, that is, the sound signal is converted into an electrical signal.

We know that sound is produced by the vibration of objects, so when a sound comes out of the phone, it must also be the vibrator on the earpiece.

So, why does the shaking happen? Let's ignore the handset first, look at the microphone first. ”

As she spoke, she took out a piece of paper and a pen and depicted the appearance of a wired telephone.

She pointed to the microphone and wrote the words "vibrate and sound".

"We know that when we speak, the vibrator on the microphone must vibrate, otherwise it is impossible to transmit sound. Then, the vibrator is connected to the electric current, and the vibration must also change the current, so that the sound signal is converted into an electrical signal and propagated.

So, what kind of change is it? Let's say it's the resistance change. ”

Qian Nawei said as she directly drew a hanging electric fan.

She pointed to the electric fan and continued to explain.

"We know that a change in resistance causes a change in the kinetic energy of an object, just like a fan, switching resistance, it will produce different wind forces. At this time, we go back to the earpiece, if the resistance is larger, the sound will be relatively smaller, and the resistance will be smaller, and the sound will be relatively larger.

At this time, if the resistance of the microphone changes continuously, a current of different magnitude will be generated, and the sound of the continuous change of size can be heard on the earpiece, thus forming a word or a sentence.

The vibration is the key to change, when we speak, the microphone vibrates, the vibrator is connected to the resistance switch, and when it vibrates, it can trip to the resistance of different sizes, so that the current changes in different sizes, that is, the sound signal is successfully converted into an electrical signal. ”

"Papa......!"

The room suddenly erupted in thunderous applause, and everyone was surprised, but they didn't expect that Qian Nawei actually figured out the principle of the wired phone!

On the side of the kotatsu, Qian Nawei lifted the hem of her skirt slightly, nodded slightly, bowed slightly, and smiled to express her gratitude to everyone's applause.

Sitting next to Qian Nawei was Qian Fei'er with a pair of squinting eyes, she looked at her cousin appreciatively and nodded slightly.

Just before, Qian Fei'er also thought about the production of wired telephones, and brought it up today to listen to the different opinions of everyone, and at the same time to see if there are people who think the same as herself.

Qian Fei'er once thought that the first one with the same idea as herself should be the most delicate Qian Nawei, but she didn't expect it to be the case.

It seems that when you don't have ideas in the future, you can discuss it with Na Wei.

Qian Fei'er thought to herself.

Then, she chatted with her cousins and cousins, as well as Hua Ning and Ling Lu and others for a while, and chatted until nine o'clock in the evening, when Qian Linjue and others left.

Qian Linjue and Linglu went out to the door of 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 there was a tendency to increase the thickness.

The thick snow-white cotton covered the ground, and Hua Ning and the others left while laughing, making a creaking sound when they stepped on it.

Linglu rushed to the yard excitedly, picked up 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.

Want to build a snowman?

He shook his head lightly and said gently, "It's late, I'll help you build it tomorrow, come over quickly, don't get frostbite." ”

As he spoke, he walked down the steps and pulled Suzulu's small hands into his pockets.

Because of the high temperature attribute of Qian Linjue's martial spirit, even through her clothes, Ling Lu can feel a burst of warmth.

It's like a real stove!

She showed a happy expression, stuffed her head into Qian Linjue's arms, and leaned her pretty face on Qian Linjue's chest as much as possible.

Qian Linjue did not refuse, and hugged this cute girl with her backhand.

While hugging Ling Lu, he also turned his head to look at a two-ponytailed girl who was about to leave the courtyard of Xuelin Palace not far away, Zi Jin.

In the face of Zi Jin, his tone was not so gentle, but turned arrogant and arrogant.

"Hey, Zi Jin, Young Master Ben ordered you to stay in Young Master Ben's room tonight to rest, and you are not allowed to go back, did you hear that?"

In the end, Qian Linjue seemed to show a little anger on her face, but in fact, the corners of her mouth kept hooking upwards after speaking, evoking an arrogant amplitude.

When Zi Jin heard this, she turned around with her hands on her waist, and the expression on her face was also arrogant, and the arrogance was no less than that of Qian Linjue.

"Do you want to be with Miss Ben so much? What a wicked idea, but Miss Ben is not such a casual person, and I won't go unless you get down on your knees and lick my feet. ”
