There are two types of Echidnas, long-nosed and short-nosed.

们会撕开软木或蚁丘等，以们长长的及黏的舌头，将猎物捕获。

After experimental data processing, material's viscousness coefficient was acquired and a new method to determine fatigue limit by the threshold of plasticity energy dissipation was given.

通过对试验数据的分析，求出了材料的黏系数，给出了利用塑能耗的起点确定材料疲劳极限的方法。
