查询词典 inversion of a point

The existing points and lines would form a closed geometric shape. If we put the new point Z outside the closed geometric shape at first and later then found that the point Z has neighboring relationship with the existing point A which is inside the closed geometric shape, we could not link point Z and A directly because that would bring line crossing. If we rearrange the point Z into the closed geometric shape, that also would cause a lot of work to do. With the help of Exclave, all problems could be solved easily. We use point X outside the closed geometric shape as the Exclave of the point A. Then the line between point Z and X could demonstrate the neighboring relationship of the point Z and A.

原有的各点和相邻线段往往会形成一个封闭的几何图形，如果我们把新增点 Z 设在原有的封闭几何图形外部，后来又发现该点 Z 和位于封闭几何图形内部的点 A 存在相邻关系，这时不能直接将两点连接因为那将产生交叉，而如果将点 Z 重新设在封闭图形内部也将导致大量的调整工作；此时借助外飞地的概念，可以轻松地解决上述问题，即在封闭几何图形外部设置点 X 作为点 A 的外飞地，两点使用同样的颜色，用点 Z 和点 X 的相邻线段表示点 Z 和点 A 之间的相邻关系。

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%)。

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。

The method makes full use of all information of manifold geophysical data, avoiding the complicated calculation in linear joint inversion, and provides a new idea for the geophysical inversion about the data fusion point of view.

该方法充分利用了各种地球物理探测数据的全部信息，避免了线性反演的复杂计算；其数据融合的观点，为解决地球物理联合反演问题提供了新的思路。

In dealing with the upper singularity point of Abel inversion transfer, a zenith compensation term is introduced, which makes simple and stable in Abel inversion process.

在Abel积分变换的上奇点的处理中，推导了大气折射指数反演的天顶补偿项，使Abel积分变换的算法更简单而且更稳定。

It is suggested that the lubrication of water phase among the waterborne particles dominates at the phase inversion point,and phase inversion progress still continues with adding more water.

所以，体系在低乳化剂浓度时，发生了不完全相反转。

The steady model is able to predict the start and the end points of the phase inversion, although the model parameters have no distinct physical meanings. The factors, such as agitation strength, density, viscosity, interfacial surface tension, grafting efficiency and volume fraction etc., have been considered in the dynamic model, which can predict the start point of phase inversion successfully.

稳态模型的参数虽然没有明确的物理意义，但却能给出相转变过程的起点和终点；动态模型则从液液分散理论出发，综合考虑搅拌强度、体系粘度和密度、界面张力、接枝效率及相体积分率等因素的影响，能很好的预测相转变的起点，略加改进后该模型可以用于相转变的全过程模拟。

Geosciences Department, Nanjing University, Nanjing 210093, ChinaAbstract With the development of exploration, the geophysicists focus their minds on the exploration and development of lithologic hydrocarbon reservoir and subtle pool. In recent years, seismic pre-stack inversion becomes the hot point of seismic attribute and inversion study.

随着油气勘探的不断深入，岩性油气藏和隐蔽油气藏的勘探开发问题日益受到勘探学家们的关注，地震叠前反演技术成为近年来地震属性分析和反演研究的热点。

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。
