With increasing of superficial gas velocities, the liquid flow regime was changed from homogeneous to transitional and radial gradient of axial liquid velocity was rather small.
且当表观气速增大,初始流体流动处于由均匀流型向过渡流型的转变,轴向液体速度在径向的梯度非常小;

Results show that the axial index gradient can compensate the effect caused by radial index gradient in some cases.
结果表明,轴向折射率梯度在一定条件下可以补偿径向折射率梯度的影响。

In this paper new ideas and improvements to the local approach are introduced, for instance yield locking by locally multi axial stress state and the effects of the stress gradient.
