渗流

Under high water pressure action, water current in rock mass couldn't be restricted in crannies.

而水的渗流问题又是影响岩体以及其上的建筑物稳定的重要因素。

Therefore, the signal of analyte could not be suppressed when using ammonium phosphate in CE/MS.

在酸性条件下，电渗流的速度降到相当低，因此缓冲溶液中的磷酸根阴离子流入质谱的量是非常少的，所以使用磷酸铵的缓冲溶液，并不会严重影响分析物的质谱讯号。

Those equations are dispersed in space by iso-parameter elementmethod and in time by using backward difference. A numerical simulator is established byFortran, the ideas of high part make the of structure program clear, maintain easy, calculationeffective.

在此基础上利用Fortran语言编制了有限元方法的油藏模拟器，采用等参元对渗流方程在空间上离散，采用向后差分在时间上离散，线性方程组的求解采用变带宽高斯消去法，该方法充分利用刚度矩阵呈条带状和其对称性的特点，大大减少了所需存储空间。

On the base of Lord Kelvin point-source solution, the integral of Bessel function, Poisson superimpose formula and boundary element method, we resolve it and obtain the boundary element basic solution.

受求解方法局限性的限制，目前经典渗流力学理论还无法精确求解复杂外边界油藏中生产井层部分射孔问题。

Based on the filtration theory, the deliverability test theory and model are discussed and the relationship between coefficient of the binomial deliverability equation and the penetration rate, depth of pay zones and skin factor are analyzed.

Chapter 2 is seepage numerical model and boundary condition.

第二章为渗流数学模型及定解条件。

We equaled the meshwork of micro channels to the resistance using the equivalent method of ion-solution and resistance. And coupling with the character of the two-dimensional separation solution and the laminar flow, we established a integrated equation of the electricity account and programmed with the software Matlab. And then we found the direction of the EOF and the range of the power control.

该方法采用离子溶液-电阻等效法，将芯片上的微通道网络等效为电阻网络，再利用基尔霍夫定律，结合MEKC-CZE二维分离时的溶液流向特点以及液流的层流特性，提出了一套完整的电流计算方程，并用Matlab软件进行编程，得到了各个阶段的电渗流的方向以及控制电压的范围。

The split between the two groups can hardly be papered over.
