Ionized molecular hydrogen can be seen evaporating from the tips of these star-forming columns of gas and dust, under pressure of ultraviolet light from the nebula's central blue giant stars.

在来自星云中心蓝巨星紫外线辐射的压力下，这些由气体和尘埃组成的恒星形成区域尖端的电离氢分子将不复存在。

But at a molecular level, in the details of its biochemistry, it is highly adapted in order to survive the high pressure.

Priede说。 “但是从分子层面来看，它的生化构造已经高度进化，以适应水压巨大的生存环境。

The model can simulate the velocity and pressure distribution of molecular in the pumping channel.

这个模型可以模拟在分子泵抽气通道内的气体分子速度与压力的分布。
