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

牠们会撕开软木或蚁丘等，以牠们长长及黏，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.

通过对试验数据分析，求出了材料黏系数，给出了利用塑能耗起点确定材料疲劳极法。
