In contrast to the graphic solution, the numerical solution can be obtained vividly, rapidly and precisely under the CAT system.

结果表明，应用数值解法在该系统下可直观快速地得到"规准"网络参数的结果，并具有较高的精度。

Numerical tests are also conducted to investigate the microphysical effects to the mesocale convective systems. The evaporation of raindrops can strengthen the surface "cold pool" to decease the temperature of rainfall center. The condensation of vapor can lower the air pressure and increase the convergence and updraft so that the convective echo develops stronger. The melting of graupel can cool the air to restrain the convective activity. The falling of precipitation particles can increase the downdraft and induce the outflow nearly the surface. The effect of condensation is the most important among all the microphysical processes. It can change the whole structure of cloud system.

微物理过程对对流系统发展和维持有重要作用：强降水的雨滴蒸发过程会加强"冷池"效应，同时增强了雨带南侧原有的地面中尺度辐合线；凝结潜热在低层诱发了与回波相应尺度的中尺度低压，增强了辐合和上升运动，促进对流发展；霰的融化吸热通过冷却大气会不利于气压下降、气流辐合抬升等过程，降低对流不稳定能量，减缓对流发展；重力拖曳使气块冷却降温，降低对流不稳定能量，并且使低层的气压升高、气流辐散，在近地面附近产生出流，加强地面中尺度辐合线的强度。

This paper presents an embedded numerical control system of grinder,including its design of hardware and software.

本文阐述了一个嵌入式磨削数控系统，包括系统硬件设计和软件设计。

Therefore, it is necessary to study numerical methods which preserve the symplectic structure of the Hamiltonian system.

因此，研究保持哈密尔顿系统的辛几何结构特征的数值方法是必然的。

Numerical simulation of the transformation of Hermite-Gaussian beams through a complicated optical system with multiple hard-edged apertures.

厄米-高斯光束经过多个硬边光阑复杂光学系统变换的计算模拟。

A quick and correct forecast of tidal current when oil spill occurs is a key step in the forecast of oil spill. Based on the harmonic constant of tidal component of M2, S2, O1 and K1 in Lingshan Island, Laoshantou and Chaolian Island, and by using harmonic method, the thesis first conducts a current forecast in a single point, and then builds up a current field forecast in Jiaozhou Bay and its adjacent seas. The computed results match well with the actual situation. The method reduces greatly the time of real time current forecast by not using numerical stimulation, so it fit to the two requirements of quickness and correctness in oil spill forecast system.

迅速准确地预测出溢油发生时的潮流情况是溢油环境预测的根本保证，因此文中根据灵山岛、崂山头和朝连岛三处M2、S2，、O1和K1四个主要分潮的调和常数资料，采用调和的方法进行单点的潮流预报，进而建立了胶州湾及邻近海域的预报潮流场；该方法的潮流预报结果与实际情况吻合良好，且因避开了数值计算过程而大大减少了流场实时预报的机时，符合溢油应急预报系统所要求的准确与快速。

The numerical tide prediction in hydrography is investigated and the Prediction and Application System of Tides in Hydrography is developed.

研究了应用于海道测量的潮汐数值预报方法，研制了海道测量潮汐计算与应用软件系统，介绍了该系统的组成与主要功能以及有关数学模型的建立与计算方法。

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。
