影响水体中溶解氧含量因素的探讨

摘要

Oxygen solubility in water is little and dynamic value,but its effect plays a deciswe role.It is direct reflection of water pollution and important indicator of water quality fresh degree,which has important influence to understand and master the condition and effect as temperature,pressure,salinity and depth etc..Studies showed that dissolved oxygen decreased with the increase of temperature,salinity and water depth,and showed certain increasing trend with the pressure increase.%氧在水中的溶解度不大并且是一个动态值,但它的作用却举足轻重,是直接反映水体污染程度和水质新鲜程度的重要指标,了解并掌握其影响条件及影响方式至关重要.如温度、压力、含盐量以及水深等.研究表明溶解氧随着温度、含盐量和水深的增加而递减;随着压力的增加而呈现出一定的递增趋势.
