my golden fishing village

Chapter 151 Don't even look at who brought it

"It may be a bit complicated to say this, so I will put it in a more popular way."

Noticing that Zhao Hao and the others looked like they were listening to the scriptures, Chen Fan coughed.

"Huh? Where did it go?"

Zhao Hao woke up from a dream.

"Mouse, you are so embarrassed, Fanzi, tell me." Han Guohua said quickly.

There is no way, not everyone is like Chen Fan, who is a god of learning, and always takes the first place in the final exam.

"To put it simply, tidal movement is regular. When the earth rotates and the sea level faces the moon, the tide will rise, and when the sea level faces away from the moon, the tide will ebb. Since the earth rotates once a day, there will be a high tide every day. fall.

In fact, this kind of deep-sea wave with ebb and flow has a period of 12 hours and 25 minutes, an amplitude of about 1 meter, and propagates from east to west.

Of course, the amplitude of the wave is affected by the combined force of the moon and the sun.

When the moon and the sun are both on the side of the earth and in a straight line, the combined force of the moon and the sun is the largest, and the water level of the tide rises the highest. Therefore, there will be two spring tides every month, usually around the first and fifteenth day of the lunar calendar.

When the moon and the sun are on both sides of the earth and form a right angle, the gravitational force of the moon on the seawater and the sun’s gravitational force on the seawater will offset part of the resulting force and the amplitude of the seawater is also the smallest, that is, the neap tide is generated, which is also the monthly tide. Twice, generally around the seventh and 22nd day of the lunar calendar. "

"In that case, I do understand," Zhao Hao nodded, although the expression on his face was still a bit confused, "Hey? Fanzi, according to you, why do I only hear that oceans have tides, but lakes don't? Aren’t they all affected by the gravitational pull of the sun and the moon?”

The scene instantly quieted down.

"Hold on, it's okay, Haozi!" Han Hanhua patted Zhao Hao's shoulder hard, and said, "Yes, why haven't I heard that there are tides in the lake?"

"Chen Fan, do you know?"

Several people looked again.

Chen Fan smiled slightly, as if he had expected it, and said: "It's very simple, because the model I mentioned is based on the fact that the earth is completely covered by oceans. In fact, the surface of the earth is not completely covered by oceans." Due to internal friction, the obstruction of the coast, and the wide variety of seabed topography, the influence of air pressure and magnetic field factors, the height of the tide, the moment and duration of the tide, the seawater will become very complicated.

For some smaller water bodies in lakes, such as moors and rivers, the amplitude of the tides is not so obvious. It turns out that this is because there is simply not enough water in these places to generate water pressure enough to overcome the gravity of the earth. "

"There's not enough water, so there's not enough power?" Han Hanhua asked.

"It can also be understood that way."

Chen Fan smiled.

Several people nodded.

"Hey, are you home so soon?"

Zhao Hao raised his head suddenly, only to realize that he had already reached the door of Chen Fan's house.

"Come back from the sea? Let me see."

Li Qiuju came over with a smile, glanced into the bucket, and said in surprise, "The delivery is not bad."

"Mom, it goes without saying, and I don't even look at who brought it."

Chen Fan smiled confidently.

"Look what you can."

Li Qiuju gave Chen Fan a white look, took the small bucket and said, "Wait, I'll do it for you."

"Auntie, let me help you." Li Fangfang said hastily.

Although they are here as guests, the food in the past two days has been very good, and the restaurants outside are all several thousand yuan.

"No, no, no," Li Qiuju waved her hands repeatedly: "You are guests, how can I ask you to help?"

"it's okay no problem."

"Yes, Auntie, I'll help you too." Ji Yun smiled.

The two girls ran to help, but Chen Fan and the others had nothing to do when they were idle, so they simply got into the RV, took out a deck of cards, and started fighting against the landlord.

Even though there are four people, Doudizhu is okay.

"Fanzi, to be honest, I'm starting to envy your little life, called Landlord." Zhao Hao suddenly raised his voice.

"not called."

"I don't bark either, there's nothing to be envious of." Chen Fan laughed.

"No bid." Qian Ning tidied up the cards in his hand, looked at Chen Fan and said, "Haozi is right, I'm quite envious."

"Not so much."

Chen Fan played a pair casually, and joked: "The local tyrants are starting to envy me as a small village chief?"

"I'm not a wealthy person."

South Korea Hua complained.

"You are the village head, absolutely!"

Zhao Hao patted a bomb and said, "If you earn 700 million a day, even if you don't open for three years, you can still eat for three years if you open."

"Yes, the income is high, and the food is good. Every day, abalone and lobster." Han Guohua licked his lips, suddenly thought of something, and said, "Hey, Fanzi, haven't we eaten abalone these days?"

"It doesn't seem like it?" Chen Fan thought about it for a while, and couldn't help but said with a smile: "Why, do you want to eat? It must be too late to catch it now, and it's not easy to get it. It's okay to go to the town to buy some."

"Okay, forget it, let's do it tomorrow."

Han Hanhua shook his head.

After all, catching the sea is a physical job.

He, who doesn't usually exercise much, is really overwhelmed.

"Let's get down to business, Fanzi, you're really nice here." Qian Ning said with emotion: "It's far away from the hustle and bustle of the city. Although it's in the countryside, the conditions are not bad. There are villagers around, and there are not so complicated interpersonal relationships. You can do whatever you want."

"This one is."

Chen Fan nodded.

"So, I really envy you."

Channing said from the bottom of his heart.

The atmosphere was unconsciously a little sad.

Chen Fan is also clear, don't look at Qian Ning's well-off second generation, who is neither short of money nor short of women, but born in such a family, not everything can be decided by you.

As the old saying goes, every family has scriptures that are difficult to recite, and it is probably the case.

"Although I can't help you with anything, if you ever get tired and want to let yourself go, I welcome you anytime." Chen Fan patted Qian Ning's shoulder and said with a smile.

Qian Ning was taken aback for a moment, but then also smiled.

"Fanzi, what about me?" Han Hanhua asked.

"And I!"

"Everyone is welcome, everyone is welcome." Chen Fan didn't know whether to laugh or cry.

"Hahaha, Fanzi, what are we going to do tomorrow? Go fishing?" Zhao Hao asked curiously.

"Yes, go fishing at noon, come back and catch the sea?"

"I can do it."

"Big boats can't go out to sea yet." Chen Fan explained: "Every time I go out to sea and come back, the fishing nets and fishing gear need to be repaired and maintained."

"So you can't go to sea?"

Zhao Hao looked a little disappointed.

After all, the purpose of coming here is to experience the sea, why not go shopping in the town?
However, it seems that it is not impossible.

"Going to sea is definitely possible," Chen Fan said with a mysterious smile, "So, tomorrow I will take you to experience a new activity, which will definitely be unforgettable for you forever."

"Let us never forget!"

"Fuck, is it so exaggerated? What is it?"
