The determined I abundance in magmatite was higher than what it should be, because of low sensitivity of the analytical method used before, and the I clarke calculated from the determined I abundance was also higher than what it should be.
过去由于使用的分析方法灵敏度不够，岩浆岩碘含量的测定结果偏高，以此为基础计算出来的克拉克值也偏高。
Relation of element concentration clarke(K) to energy depletion is introduced and discussed.
本文在理想化的假定条件下，借助于热力学与信息学的基本概念和原理，讨论并推导出元素浓集克拉克值Ｋ分别与热力学概率Ω、热力学熵Ｓ以及信息量Ｉ的非线性关系表达式；引用并探讨了元素浓集克拉克值Ｋ与成矿能耗Ｅ之间的关系。
Moreover, the average chemical compositions of las were very close to Clark values of crust, which are us.
并且，黄土的平均化学成分十分接近现在使用的地壳克拉克值。
