塌陷

In real accidents one drops at relatively low speeds, often less than 10 m/s, because the broken hang glider or collapsed paraglider greatly slow the descent. Rapid deployment of an emergency parachute is indispensable especially for these low speeds.

在实际的事故当中，通常都是飞行员以一个相对较低的速度下坠，通常是低于10米每秒，这是因为坏掉的三角翼或者已经塌陷的主伞大大降低了下坠速度，所以备份伞必须要在这种低速情况下有效迅速的打开。

This point was just above the tumbled hummocks of an icefall, where the movement of the glacier , he said, would tend to bring the body closer to the surface

The density is in 150~2200 kg/m3 and the thermal conductivity is 0.0599W/m·K, density of 150 ~ 2200 kg/m3, thermal conductivity for 0.0599W / m · K. It has a great many merit such as anti-aging, thermal insulation, incombustible, environmental protection, benefit waste, acoustic, noise, low-cost (production cost of 40 ~ 70 yuan / m3), which is a waste of new energy-saving insulation materials benefit.
