We named it Stokes method which use four parameters to describe the polarization of light beam. The four parameter use the same physics dimension.

描述光束偏振态的最普遍的方法，是用一组物理量纲完全相同的参量——斯托克斯参量来描述。

So it is very convincing to use such light hydrocarbon parameters to evaluate reservoir characteristics and water washed and water flooded degree of developed oil layers.

因此，用此类轻烃参数评价储集层性质和已开发油层的水洗、水淹程度更有说服力。
