Fire did not break out and within a minute those capable of walking began staggering out of the ruptured plane, stepping over debris and burst suitcases.
没有发生火灾，一分钟内那些能走动的人难以置信地从断裂的飞机中走出，跨过散落的碎片和断裂的手提箱。
Mineral powders are good crystalline, and they break along the cleavage plane when they are comminuted, which cause the mineral powders have flat surfaces and sharp edge angles.
但是由于矿物晶体粉碎过程中表现出沿解理面解理破裂的强烈倾向，使得矿物粉体表面具有平整的解理面及尖锐的棱角。
The test results with the needle-plane electrode system under ac voltage at 77 K indicate that the fatigue break in UHMW-PE under mechanical forces during the electrical treeing is a critical factor.
结果表明，机械应力下疲劳强度的劣化是低温电树枝化的重要因素。超高分子量聚乙烯具有低温性能好。
