本文通过对冀中古潜山地下热水中主要阳离子Na~+、Ca~(++)、Mg~(++)浓度与它们的键参数之间关系的研究,得出Na~+、Ca~(++)、Mg~(++)浓度的对数与键参数成直线关系,即LogMi=a+bL(X、z/r、z~2/r)。a、b值是与地球化学环境有关的常数,特别是b值能反映地下温度和压力的变化,是探索地震预报值得重视的一个参数。 In this paper, we study the relationship between the concentration of Na ~ +, Ca ~ (++), Mg ~ (++) and their bond parameters in underground hot water of buried hill in Jizhong, (++). The logarithm of Mg ~ (++) concentration has a linear relationship with the bond parameters, that is, LogMi = a + bL (X, z / r, z ~ 2 / r). The values ​​of a and b are constants related to the geochemical environment. In particular, the value of b can reflect the variation of underground temperature and pressure, which is an important parameter for exploring the earthquake prediction.
