地动仪

张衡地动仪与公元134年陇西地震

Zhang heng ′ s seismometer and Longxi earthquake of 134 ad

中国的张衡在汉朝时发明了地动仪。

China 's Zhang Heng invented the seismograph during the Han Dynasty .

地动仪全部用精铜铸成，结构非常精细巧妙。

The seismograph was made of fine copper , and was ingeniously constructed .

张衡和地动仪

Zhang Heng and the Seismograph

张衡发明的地动仪以青铜铸成，四周镶嵌以八条龙，龙头朝下。

Heng 's creation was a heavy bronze vessel with nine dragons facing downward embedded into its outside .

张衡则以高超的工艺制造了“浑天仪”、“地动仪”等科学仪器，观察天象，感应地震。

Zhang Heng invented seismography and the Armillary Sphere so as to observe the universe and perceive earthquake .

公元132年张衡发明制造侯风地动仪是世界上第一台感知地震的仪器。

This seismograph was invented by Zhang Heng in A.D.132 , as the world 's first instrument to sense earthquakes .

这一最初的地动仪虽然有点简陋，但比起西方发明的地震仪仍然早了1500多年。

This first seismograph seems a bit basic , but it would be another 1500 years before Western nations developed their own versions .

在地震学上，他发明了候风地动仪，是世界上的地震仪之祖，比其它类似设备早了1800年。

He was renowned as the inventor of the world 's first seismograph , which was invented 1 800 years earlier than other similar devices .

早在公元2世纪前叶，汉代天文学家张衡就创造出了地动仪，他发明的地动仪还巧夺天工、壮观宏伟。

Not only did imperial astronomer Chang Heng create a seismograph during the Han Dynasty in the early second century , he created a magnificently beautiful one .

清朝末年，以张衡地动仪为代表的科学思路在海外得到发扬，诞生了现代地震学。

In the last years of the Qing Dynasty , the scientific train of thought represented by the seismograph of Zhang Heng was promoted overseas , and modern seismology came into being .

中国东汉科学家张衡于公元132年发明的地动仪是世界上最早的地震仪。

The seismograph invented in 132 A.D. by Zhang Heng , Chinese scientist of the East Han Dynasty ( 25 A.D. - 220 A.D. ), was the first seismograph in the world .

汉代张衡发明了测定地震方位的地动仪和演示日月星辰的浑天仪。

Zhang Heng ( 78-139 ) of the Han Dynasty invented a seismograph to determine the location of earthquakes and an armillary sphere that showed the movement of the sun , moon and other stars .

他一生做出了许多设计与发明，如水运浑天仪、候风地动仪、指南车、记里鼓车等，并在国际上拥有广泛地影响力。

He did a number of inventions and designs all his lifetime , such as Armillary , Seismoscope , Southward Pointing Chariot , Li-drum-hodometer and so on , which have wide influence on the international arena .

此时，“悬摆锤”来回摆动引发地动仪内部的杠杆活动，从而触动机关，使得地震源方向的龙头张开嘴，吐出铜球，落到铜蟾蜍嘴中。

This would trigger the release of a ball held in the mouth of the dragon facing the direction of the earthquake 's epicenter . The ball would then fall into the mouth of the frog directly below it .

他根据自己对于地震现象的观测，于公元132年在京城洛阳制成了“候风地动仪”，这台仪器成为世界上第一台观测地震方向的仪器。

As a result of careful observations of earthquakes ， he invented a seismograph in the then national capital of Luoyang in 132 AD ， which was the world 's first instrument to identify and ascertain the direction of earthquakes .

尽管古代中国人并不能准确地告知世人一场地震是里氏几级（因为直到1935年里氏震级才被发明出来），但他们却设法发明了世界上第一个地震测量仪——地动仪。

Although the Chinese couldn 't tell anyone exactly what an earthquake measured on the Richter scale ( since the Richter scale wasn 't created until 1935 ) , they did manage to invent the world 's first earthquake detector -- a seismograph .

通过对历史上京师地震和陇西地震文献记载的分析，进一步否定了用公元143年陇西地震来测试地动仪的可能性。

Through analy - sis of the literature about the earthquake in West Gansu and the earthquake in the Capital in history , the possibility of using the West Gansu earthquake that occurred in AD 143 to test seismograph 's function is denied again .

铜球就会掉进铜蟾蛛的嘴里，自动报告发生地震的方向。公元138年的一天，地动仪西边的龙嘴吐出了铜球。

The dragon facing that direction would open its mouth ， and the ball would fall into the mouth of the toad below , automatically indicating the direction of the earthquake.One day in 138 AD ， the dragon in the west expelled its ball .

考察地动仪及其设计思想在中国古代的流传情况，可以看出古人对地动仪的质疑早已有之，而且越来越明显与强烈。

On the other hand , from the spread of the designing thought of the instrument in ancient China , it is very clear that the doubts about the instrument had appeared from very early times , and were becoming more and more obvious and strong .

由博学著称的中国发明家张衡发明了世界上第一台地震仪，这台地震仪也是他最伟大的成就之一。这台发明于公元132年的仪器的名字叫做“候风地动仪”。

The famed Chinese polymath Zhang Heng has the world 's first seismograph to add to his impressive list of achievements.The invention known as Houfeng Didong Yi ( " instrument for inquiring into the wind and the shaking of the earth " ) was created in A.D. 132 .
