In addition, the factors which influence residual phase and the precision of compensating are analyzed.

在目标高速运动的情况下，解调频处理和目标运动产生的残余相位对二维成像的影响不可忽略。

A complete boundary integral formulation for incompressible Navier Stokes equations with time discretization by operator splitting is developed by using the fundamental solutions of the Helmhotz operator equation with different orders.

利用不同阶次的Helmhotz算子方程的基本解，建立了时间离散不可压缩Navier－Stokes方程的完全边界积分表示式。

The primary objective of this thesis is to use multigrid method for solving nonseparable elliptic equations with Dirichlet boundary condition on a rectangle. Of course, this method can be applied with any boundary conditions.

这篇论文主要之目的是使用多重网格法来解一些不可分离的椭圆方程式有著Dirichlet条件在矩形的区域上(当然这种方法也可应用在其他的边界条件下)。

When material is uncompressible, a group of four-sectors solutions and a three-sectors solution in which the elastic-unloading region vanishes are given respectively in the condition of supposing some singularity of curvature on the boundary between two regions.

第一部分首先考虑了不可压缩(ν=1/2)理想塑性材料，在假定区域交界线的曲率有一定奇异性的条件下，得到了裂尖场的一组四区解及不包含弹性卸载区的三区解。众所周知的由高玉臣。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
