Where is the geodynamic instrument? Does a ground motion meter work?

The geokinetic instrument is an ancient thing, and now it is useless at all - at 14:28 on May 12, 2008, it occurred in Wenchuan, Sichuan Province (east longitude, north latitude). **Caused most parts of the country to feel, many netizens are questioning why there is no forecast today**, but when the reporter checked the online information, he found that many phenomena before indicated that there would be**. On May 9th, a netizen posted on the post bar:

Tens of thousands of small toads suddenly appeared on the Dongfeng Bridge in the urban area of Taizhou City, Jiangsu Province, and it was understood that "a large number of small toads had to migrate collectively in order to find a new living space in the river water due to the lack of oxygen in the river recently". Hundreds of thousands of toads in the first three days of Sichuan changed according to the **popular science network. For the first disaster, it is not yet possible to make an accurate forecast, but long-term observation and research have shown that there will be some signs before the first disaster, such as abnormal animals, abnormal groundwater and so on.

This still has a role to play in the prevention. Attached: **Phenomenon song recipe Before the earthquake, animals have omens, and group detection and group prevention are very important.

Cattle, sheep, mules and horses do not enter the pen, and chisels do not eat and eat dogs to bite. Ducks don't go into the water to make trouble on the shore, and chickens go up the trees and cry loudly. The snake came out of the hole in the ice and snow, and the big cat ran with the kitten.

The rabbit jumped and bumped into the water, and the fish jumped on the surface of the water in panic. The bee colony is booming, and the pigeons are frightened and do not return to their nests. Every household observes and makes a forecast of the comprehensive anomaly.

Taiwan's Taichung Gymnasium is there!

Useful. It is an instrument for testing ** in ancient times.

The geodynamic instrument is a masterpiece created by Zhang Heng, a scientist in the Eastern Han Dynasty of China. In the Eastern Han Dynasty in which Zhang Heng lived, ** was more frequent. Zhang Heng has a lot of personal experience in **, in order to grasp the national ** dynamic Huai Tong state, after years of research, he finally invented the wind geodynamic instrument in the first year of Yangjia (AD 132), which is also the world's first geodynamic instrument [1].

The geodynamic instrument has eight directions, each of which has a dragon head with a dragon ball in its mouth, and a toad corresponding to it under each dragon's head. If there is a ** occurrence on either side, the dragon ball contained in the dragon's mouth in that direction will fall into the toad's mouth, so that the direction of the occurrence of ** can be measured.

On December 13, 134 A.D., one of the dragon machines of the geodynamic instrument suddenly started, spit out a copper ball, and fell into the mouth of the toad. At that time, the people in Jingshi (Luoyang) did not feel the slightest sign of **, so some people began to talk about it, blaming the ground for not working. Within a few days, someone in Longxi (now Tianshui District, Gansu Province) reported that it had indeed happened there a few days ago, so people began to be extremely convinced of Zhang Heng's superb skills.

Longxi is more than 1,000 miles away from Luoyang, and the geodynamic instrument is correctly marked, indicating that its seismic sensitivity is relatively high.

However, due to the long history, Zhang Heng's geodynamic instrument has been lost, leaving only more than 100 words of written records.

The geodynamic instrument is a masterpiece of the Han Dynasty scientist Zhang Heng. According to the "Book of the Later Han Dynasty: The Biography of Zhang Heng", there is a bulging round lid on the wind and ground motion instrument, and the appearance of the instrument is engraved with seal inscriptions and figures such as mountains, turtles, birds, and beasts. There is a copper "capital column" inside the instrument, and there are eight channels next to the column, called "eight channels, as well as ingenious machines and gates."

There are eight dragon heads around the outside of the bottle, which are arranged in eight directions: east, south, west, north, southeast, northeast, southwest and northwest. The faucet is connected to the engine in the internal channel, and each faucet has a copper ball in its mouth. Facing the dragon's head, eight toads squatted on the ground, each with their heads raised and their mouths open, ready to take on the copper ball.

When ** occurs in a certain place, the bottle body moves with it, touches the mechanism, and makes the dragon head and swim in the direction of ** open their mouths, spit out copper balls, and fall into the mouth of the copper toad, making a loud noise. So people can know the direction in which ** is happening.

Copying it online, I don't know if it can help you.

Always play a role when the ** comes.

If it happens within a certain range, he will tell you where it is, which means that it will happen in that place.

When ** happens, you can tell only that direction.

A primitive instrument for detecting **, which can report the general direction of the epicenter at **, which helps the imperial court to know in time which direction ** has occurred, so as to respond. It was the most advanced instrument at the time, and it was the only one.

If it's good, don't drink, don't add it, don't add it, don't add it, don't add it, don't see it for a long time, don't see you for a long time.

Pretend to be able to measure**! Never worked out!

The ground motion instrument can measure the approximate orientation of ** after **.

The geodynamic instrument is a masterpiece created by ancient Chinese Han scientists, invented by the astronomer Zhang Heng in the Eastern Han Dynasty, and Zhang Heng lived in the Eastern Han Dynasty, which was more frequent. Zhang Heng has a lot of personal experience in **, in order to grasp the national ** dynamics, he after years of research, and finally in the first year of Yangjia (AD 132) invented the wind geodynamic instrument, which is also the world's first geodynamic instrument.

According to historical records, it can be measured in which direction ** occurred. However, at present, some historians are skeptical of the historical records, mainly because the historical data show that there was no historical record at that time, and the other ** geodynamic instruments have not measured it.

Personally, I don't think it's very credible.

The effect of the ground motion instrument is not obvious, and it can only measure the occurrence of ** and the direction of **occurrence for the imperial court as a reference for timely disaster relief.

It is rumored that it will be possible to measure the approximate position of ** after **, but now there is a lot of debate, and some dissenting people say that this is just a conjecture and a model in itself.

The ground motion instrument is an ancient seismic detector that can be used for ****, but it does not have the effect of forecasting.

No**.

When it is, it can indicate the direction of occurrence.

Modern technology can't**, let alone the Eastern Han Dynasty.

It was invented by Zhang Heng of the Eastern Han Dynasty and can be used for ****. Of course, it didn't work so well.

The approximate orientation of ** was measured later.

Zhang Hengzao's can **** happen.

Invented by Zhang Heng, **** direction.

The ground motion instrument is not the first one, it is to determine the first direction as soon as possible and send rescuers over in time.

From this concept, the geodynamic instrument is useless in this era, because the current communication is too developed

Location at the time of occurrence.

It can be known that **happened**.
