1、During the second actual trapping phase, the stored elastic energy is released.
在捕獲瞬間，彈性能量被釋放了出來。

2、Meanwhile the thicker the coal in the combined sample is, the greater the elastic energy index is.
組合煤巖試樣中煤層厚度越大，則其彈性能指數就越大。

3、The recovered energy is the elastic energy that is stored during reeling.
可恢復的應變能量是一種在纏繞過程中被儲存的彈性能。

4、Its elastic energy index increases with the increase of percentage of coal.
彈性能指數隨著煤樣百分比的增加而呈現增加的趨勢。
