Feldman examined some properties of CLMC and found that it is neither an intensive nor extensive thermodynamic variable, and proposed a simple alteration of CLMC that renders its extensive. However the remedy results in a quantity that is a trivial solution of the realizes compensatory form of density and not as a measure of structure.

David详细研究了CLMC 的特性，发现它既不是一个热力学集中变量也不是一个热力学扩张变量，并提出一种满足热力学扩张特性的补偿形式，但最后证明CLMC 只是熵密度的普通解，不能作为结构测度。

If adopting the reliability analysis approach for geotechnical engineering, the uncertainness of various influencing factors, especially uncertainness of geotechnical parameters and calculated approach must be considered.
