seawater pollution

The main kinds of the geological disasters are water loss and soil erosion, expansive soil hazards, rivers bank collapse, ground subsidence, water and soil pollution, landslide, debris flow, seawater intrusion, rock desertification in rocky area, etc.

广西主要地质灾害有水土流失、膨胀土地质灾害、河岸崩塌、地面塌陷、水土污染、滑坡、泥石流、海水入侵、山区石漠化等。

The solar heating equipment invented by. Zhang can be used as a good energy source, which is clean and brings no pollution to the environment, for seawater desalination devices.

河海大学和南京玻纤院等研制的太阳能加热装置，可以作为海水淡化装置中清洁、无污染的能源。

For the pollution ions were existed on the specimens when they emerged from seawater, the dealloying corrosion of double phase brass exposed to mean tide zone was also accelerated.

由于这种污染元素的作用在试样露出水面时依然存在，致使潮差暴露也出现类似情况。
