摘　　要：张衡地动仪是我国古代科技的光辉典范,因早已失传,一百多年来国内外争相复原,已达40多种版本,但尚未达到原有水平。为此,探讨了它的工作原理,明确了它的性能要求,提出了倒立摆方案,开展了模拟陇西地震试验。结果表明,新方案已能实现对东汉陇西地震的敏感,并产生触发吐丸等系列动作。理论分析和实验表明,历史上的张衡地动仪是真实存在的,怀疑甚至否定中国古代科技光辉的论断都是站不住脚的。Though a shining example of the achievement of ancient science and technology,the original Zhang Heng Seismoscope was lost long ago.Up to now there have been over forty reconstructed models in the world since the 1880s.This paper discusses its working principle,puts forward its performance requirements and introduced the upside-down-pendulum flex structure.Then a test was carried out to simulate the earthquake test recorded in history.The test indicates that the new flex structure has high sensitivity,which could have sensed the Longxi earthquake and therefore touched off a pellet falling out.Theoretical analysis and experimental results show that the existence of the Zhang Heng Seismoscope in history should be out of question,and all suspicions and even denials of the achievements of ancient Chinese brilliant technology are untenable.
