盐度是海水的基本特征之一。
但是海水的盐度影响它的重要及冰点。
The salinity of sea water affects both its weight and freezing point.
取样的海水中，盐度为千分之二。
In the sea water sampled the salinity is two parts per thousand.
海洋声速、声衰减、温度、盐度、悬浮物等都是海水的重要参数。
Ocean sound speed, attenuation, suspended sand size and so on are all important ocean parameters.
