The first rank derivative is a reflection of curve change and its rate, at certain range, if the sign of the first rank derivative has changed, the logging value of the correspondence depth point means maximum in this range; the second rank derivative is the knaggy property reflection of curve, at certain range, if the sign of the second rank derivative has changed, the correspondence depth point represent the inflexion of geophysical logging curve, it＇s also a turning point of the reflection of knaggy change property of the curve, it is the interface of stratum.

测井曲线的值是深度的函数，测井曲线的一阶导数表示了曲线变化的趋势和变化的快慢，在某一范围内，当一阶导数呈现符号转换时，相对应的深度点的测井值即为该范围内极大值；测井曲线的二阶导数则表示曲线的凹凸性，在某一范围内，当二阶导数呈现符号转换时，相对应的深度点代表了测井曲线的拐点，即反映曲线凹凸性变化的转折点，亦即地层的分界面。

在不通过探测器响应函数进行数据转换的条件下，利用中子的能量直接确定了中子的有效测量阈值。

Moreover,the flocculation settlement curves of the lignin locution were determined at deferent temperatures under the condition of the polyaluminum ferric chloride flocculation,the sense of the inflexion point of the curve was discussed,and the acaivation energy of the colloid solution flocculatiov was eltimated,which corresponds to the potential-energy between sol particles accordin.

用传统的化学动力学方法讨论了温度对絮凝过程的影响，测定了木质素溶液在不同温度时被聚氯化铝铁絮凝的絮凝沉降曲线，讨论了曲线上拐点的意义，并估算出该胶体溶液絮凝时的活化能，它相当于DLVO理论为胶体粒子间的势能能垒φm，实验得出φm≈16.5k
