The above problems are studied in this thesis. First, the implicit NND scheme with mix flux splitting method proposed by Zhang Hanxin that is first order accurate in time and second order in space is modified. The modified scheme keeps the characteristics of fast convergence and is second order accurate both in time and space. It can be capable of simulating the unsteacly flow. Second, the topological method founded by Zhang Hanxin is improved to study the characteristics of vortex near the singular point on its axis and the cross streamlines on the longitudinal section passing the vortex axis. On the basis of topological results, a program which visualises numerical results is made out. It can help us analyse the characteristics of vortex motion.

本文对上述问题做了研究：第一，在数值模拟方面，借助于张涵信提出的NND算法和混合通量法，我们将他建立的时间为一阶、空间为二阶精度的快速隐式算法推广为时间和空间均为二阶精度的算法，这样做保留了原格式收敛快的特点，而且能适用于真实的非定常流态的计算；第二，将张涵信的拓扑分析方法加以推广，研究了涡轴附近及破裂点邻域内流场的空间特征，并以这些拓扑分析结果为指导，研制了一套显示计算结果的软件，这一软件能很好地帮助我们分析流场的计算结果和旋涡演变的特征。

The analysis shows that with given grid size higher accurate difference scheme can give higher resolutions with wider range of scales, or with given accuracy large grid size can be used for the higher accurate difference scheme. The second part is the numerical simulation of two-dimensional axisymmetric jet. The simulation results show the structure in the near field and the initial transition. In the near field, Kelvin-Helmholtz instability leads to the formation of vortex ring, and nonlinear growth leads to the merging of vortex ring. This is the main instability form. Under the assumption of axisymmetry and two-dimensional computing conditions, the results are applicable only in the near field.

第二部分采用高精度的差分格式对二维轴对称射流进行了数值模拟，模拟结果显示了射流流场结构和涡结构的发展过程，在射流流场近区，K-H失稳导致涡环的产生以及非线性效应的增长导致涡环的对并是射流失稳的主要形式；分析指出在轴对称假设下的射流数值模拟只适用于射流近区的分析。

The Eddington scheme is slightly more accurate in thicker optical depth region, while the two-stream DISORT is more accurate in the thin optical depth region where the solar zenith angle is less than 60 degree. Second, we compare the two two-stream schemes in a realistic atmospheric profile with gaseous transmission considered.

对于单层大气，Eddington 近似在光学厚度大的时候比二流离散纵标法更精确一点；而二流离散纵标法在光学厚度小且太阳天顶角小于60 度的时候更准确。

Like Meguiar's Swipe Test, is a more accurate indicator of whether a wax has fully dried and is ready to remove, Meguiar's Squeak Test is a more accurate indicator of whether or not their is wax on the surface.

就像美克拉的擦拭测试，它是一个可以更准确指出蜡是否已经充分乾燥且可以准备擦除的试验方式，而美克拉的滑音测试则是一个较准确判断表面是否有上蜡的试验方式

Among routine three impulse control system, because reason of " false liquid location" make steam load rise and drop dynamic characteristic when curve asymmetric, degeneration, can't ask out the accurate mathematics model when and there are the systematic parameters, can't design the accurate feedforward controller either, can only realize the static feedforward , can realize that there is not error in the stable state , but does not control dynamic performance well.

而在常规的三冲量控制系统中，由于&虚假液位&的原因使得蒸汽负荷上升和下降时的动态特性曲线不对称，且系统参数具有时变性，不能求出准确的数学模型，也就不能设计出准确的前馈控制器，只能实现静态前馈，能实现稳态无误差，但对动态性能控制不好。

Because accurate post fit is important to maximize both retention and support, the screw post should be used with the matched post/reamer syste; and accurate contrangle drilling should be maintained.

由于根柱和根柱孔的精密吻合，对于固位及力量传递的支持有重要的影响，因此打桩时要精确做到根柱孔的乡钻制，对于偏斜的弯机要避免使用，而且要选用同号组合配对的钻针。
