武山1号泉流量、O2＋Ar、N2、He的异常变化分析

Analysis on the Abnormal Changes of Outflow,O_2+Ar,N_2 and He in No.1 Spring at Wushan Station

对武山台1号泉气体资料显示,在1997-1999、2003年流量有几次明显的突变,同时气体组分O2+Ar、N2、He百分含量与流量呈完全同步变化。本文分析了造成流量突变的原因,认为流量大幅度变化不是自然动态的。同时用试验方法验证了影响气体组分O2+Ar、N2、He百分含量变化的主要因素是流量、冲流时间和空气混入了泉水,并分析了它们之间的相互关系及变化特点。

The gas data of No. 1 spring at Wushan station show that there were some obviously abnormal changes of outflow from 1997 to 1999 and in 2003, meanwhile, values of O2＋Ar, N2 and He in the gas abnormal changed completely and synchronously with outflow. In this paper, the reason of the changes of outflow is analyzed. It is considered that the significant variety is not a dynamical nature. It is tested and verified by experiment that the influence factors on values of O2 ＋Ar, N2 and He in the gas in spring water are outflow, circulation time and air sneaked into the water. The relationships and change characteristics are analyzed also.
