张衡地动仪的外形需要重新复原

目前，中国最流行的王振铎1951年复原的地动仪模型，不仅工作原理和内部结构不对，其外形也是错误的。这个外形既不符合中国古代文献记载，也不符合考古发现的汉代文物，更被灵台遗址的考古发掘结果所否定。因此，不能继续用这个模型的外形再进行广泛的社会宣传。重新复原已是不可阻档的历史潮流。坚持不改，拖延下去，会有损于中国古代文化乃至今天中国的形象。在重新复原时，对于模型的整体外形、蟾蜍、龙以及其他装饰的处理问题，提出了应该遵循的3个原则。

Reconstruction of the external form of Zhang Heng's Seismoscope

The reconstructed model proposed by Wang Zhenduo in 1951 is most popular in China, but is not sounded in both working principle and internal structure. It is also necessary to point out that the reconstructed external form of this model is completely wrong, due to its not according with historical literatures, unearthed relics of Han-dynasty and archaeological ex- cavation in Lingtai. Therefore, it is not suitable to take this external form of the model as a standard for further public exhibition. Reconstructing once more is a normal historic pro- gress. Insisting this model or delaying could do us harm to the image of Chinese ancient culture and today＇s China. As far as the design of external form, toads, dragons and other decorations of the new model, three principles in reconstruction are suggested in the paper.
