to penetrate a surface

If the burst is shallow enough to penetrate the surface, blast, thermal, and initial nuclear radiation effects will be present, but will be less than for a surface burst of comparable yield.

如果离地面够浅以致能穿透表面，那么将出现冲击波、热辐射以及早期核辐射作用，但是作用效果要小于近似当量的地面爆炸。

This allows more solar radiation to penetrate the earth's atmosphere, which promotes a climate forcing effect (more short wave radiation reaches the earth, warming land and sea-surface temps).

这使得更多的太阳辐射穿透地球的大气层，从而促进气候强迫作用(更短波辐射到达地球，升高陆地和海洋表面气温)。

A multi-function cleaner, used to clean floor and other hard surface, can penetrate the dirt and bemirch and any dirt and cicatrice will not be left.

本品是一种功能众多的清洁剂，最适用于清洗地板和其它硬质表面，它能渗透污垢、污渍，且不留下任何斑痕和垢膜。
