Maximum influencing factors of flow fluctuation coefficient are the elastic modulus of the oil and the working pressure of the pumps, the piston number being a minor factor.

同时指出流量脉动系数最大的影响因素是油液的弹性模量和油泵的工作压力，其次是柱塞数。

Because of the nonlinear effect caused by flow pattern, oil diameter and absorption coefficient etc, it is difficult to establish the measurement model.

但由于受流型、油泡直径及吸收系数等因素的非线性影响，使得测量模型难于建立。

In chemical flooding, consistency coefficient of the oil displacement agent declines exponentially, the power law exponent increases linearly in the direction of percolation flow.

在驱油过程中，驱油剂的稠度系数沿渗流方向呈指数规律减小，而幂指数则以线型规律递增。
