Combining with the analysis of flow pattern transition, the input water cut at phase inversion point is around 60%. The relational equations that water holdup is influenced by input water cut and mixture velocity are obtained before and after phase inversion point.

但随着入口体积含水率的增加，在一定的折算气液速的条件下，压力梯度出现了与转相相关的峰值特性，由峰值对应的液相入口体积含水率确定转相点对应的液相体积含水率为40%，明显低于油水两相流动时的转相点(入口体积含水率约为60%)。

It is shown that the phase inversion is complete, which means that all water molecules in the system are transformed to be continuous phase at the phase inversion point. The viscosity of the system before the phase inversion point is almost constant independent on stress, which is the characteristics of Newtonian fluid.The systems after the phase inversion point exhibit high viscoelasticity and strong pseudoplasticity at relatively high stress.

结果表明，乳化剂浓度较高时，体系发生完全相反转；体系在相反转点前为W／O结构，其粘度几乎不随剪切应力的改变而改变，表现为牛顿流体行为；体系在相反转点后为O／W结构，具有很高的粘弹性，并且在较高剪切应力下表现为典型的假塑性。

Corresponding to the phase inversion point, a sharp peak in pressure gradient also appears at some gas and liquid superficial velocities. It is found that the input water cut of the phase inversion point for three phase flow which is around 40%, is obviously lower than that for two phase flow, which is around 60%.

采用互相关技术分流型研究了油-气-水三相分层流和环状流界面波速特性，结果表明：固定油水比时，SW‖ST流型气-油界面和油-水界面波速、AN‖DO/W流型和AN‖DW/O流型的气液界面波速均随折算气速和折算液速的增大而增大。

Also the multi-scale entropy processing and analysis of conductance fluctuating signals acquired by VMEA sensor for five flow patterns with water as the continuous liquid are conducted. The study result indicates that the increase of f o makes oil in water type slug flow occur at lower U sg; for low flow velocity, the continuous liquid inversion occurs at about f o=0.9 and the increase of U sg makes the inversion point move to low oil volume fraction; the multi-scale entropy detail describes the nonlinear dynamic characteristics of oil-gas-water flow patterns and the rate of MSE at low scales sensitively indicates the variation of flow patterns and can act as the efficient criterion of three-phase flow patterns identification.

对水为连续相的5种流型VMEA传感器波动信号进行了多尺度熵分析，研究结果表明：含油率增加可使水包油段塞流在较低气相表观速度下产生；较低流速下的油水相态逆转可发生在油液比为0.9左右，气相流速增加使得逆转点向含油率低的方向偏移；多尺度熵细节可以刻画油气水三相流非线性动力学特性，而低尺度的多尺度熵变化率敏感地反映流型转变，是划分油气水三相流流型的有效准则。

This is not an ordinary box, which is used as a background picture of the dialog box, very pretty.

详细说明：这可不是一个一般的对话框，它是用图片作为背景的对话框，非常好看。
