胶结

Clearly there is scattering in data, which may be related to the different degree of cementation, different mineral properties, and different grain size and contact.

很显然，数据在此有散点，造成这种现象是由于胶结程度不同、矿物特性不同及颗粒尺寸和含量的不同。

The cementation factor m or the factor a in Archie's equation are affected by temperature too.

胶结指数m或阿尔奇公式中的比例系数a同样受温度影响。
