seismograph

Earthquakes are recorded with a seismometer, also known as a seismograph.

The name of a seismograph invented by the ancient Chinese scientist, Zhang Heng.

Zhang Heng instituted, people immediately think of his invention of the seismograph.

In 132 AD, in the then national capital of Luoyang, Zhang Heng made the ancient seismograph to determine the direction of an earthquake.

So more likely, it was just to illustrate the magic of the seismograph invented the story.

People laughed at Zhang Heng when he first introduced his seismograph, and it was only later that the world recognized his greatness.

Zhang Heng invented Armillary Sphere and Seismograph here; and the great poets Du Fu and Li Bai left their ever-lasting poems here.

Seismograph, intensity and magnitude, distribution of earthquake. Effects of earthquake.

A seismograph is an instrument which gives a continuous record of the motion of the ground.

An earthquake's magnitude is measured by the strength of the waves recorded on the seismograph.

Seismograph the seismograph is Han Dynasty scientist Zhang Heng another is handed down for generations the masterpiece.

The reluctance seismograph implies a variation of the principle of the moving-coil seismograph.

Any earthquake at any distance from a calibrated seismograph is nowadays assigned a magnitude.

equivalent to a broadband seismograph in a borehole of 2500 m deep.

The protection of acquisition system of seismograph from lightning appears more important.

Zhang design and manufacturing armillary sphere, waiting for the moon and stars, and seismograph did many observation and analysis.

The advantage of digital seismograph has been brought into full play.

In the Exhibition Hall of the Museum of Chinese History in Beijing, there is a restored model of the first seismograph.

is a seismograph whose physical constants are so well known.

Chang's Seismograph construction thinking has been enlightened by chandelier of period of Han at archaeology work.

The most basic tool of seismologists is the seismograph network.

Separated by 1700 years, Europeans to create a "first " seismograph.

In 2000, the French expert was adjusting the 408CMXL digital seismograph at site.

In 1897, Japan first installed the seismograph newly invented by Milne in Taipei ( Abu Shengzheng, 2000).

It is used in measurement of pressure transients , such as in shock tubes , wind tunnels , and seismograph equipment .

Seismograph shows the earthquake can not be detected.

Also, who is smart like seismograph, omnipotent spy Xiao Ma.
