摘要
为掌握湖水结冰过程中及冰冻条件下溶解性总固体(TDS)在垂直方向的分布规律,采用标准方法,考查呼伦湖冰封期的冰体和水体中TDS的质量含量,并进行相关数据分析.结果表明,结冰过程可以促进TDS由冰体向水体的迁移,使冰中的TDS质量含量小于水中的质量含量,并且大量的迁移发生在冰体生成的初期,与冰的生长速率成正相关;随着冰层厚度的增加,水中TDS的质量含量也会上升,但结冰过程对水体不同深度中TDS的质量含量变化影响不大.
In order to understand its vertical distribution rule during the freezing process and under the frozen condition of lake water,the co-authors examined with standard method total dissolved solids＇（TDS）quality content in ice and water of Hulun Lake during frozen period and then analyzed related data.The result shows that the freezing process can accelerate the changing of TDS from ice into water,making the quality content of TDS in ice less than that in water.Most of the changing happens in the initial period of ice body generation,which is positively related to ice＇s growth velocity;the TDS quality content in water increases as the addition of the ice layer＇s thickness,but the freezing process shows little impact on the TDS quality content variation in water of different depths.
