Comparing a value with lgn,it was found out that there varying trend was consistent and the relation of the both was close.
通过对鲍店煤矿实际矿山地震分析,应用G-R关系,计算出矿山地震的G-R关系曲线,做出参数a、b值变化曲线,把b值变化与实际矿震中大震个数与小震个数比值进行比较,可以发现两者变化趋势相反,a值与lgn比较,变化一致,两者存在紧密的关系,证明a描述了矿山地震总体活动性水平。

补充资料：酯值
分子式：
CAS号：
性质：油脂类物质的皂化值与酸值之差数称为酯值。酯值代表油脂类物质中甘油三酸酯的含量。即1g样品内皂化中性油脂所需氢氧化钾量(mg)。
