The present method has not only solved the field distribution computation of irregular domain, but also overcomed limitations of mesh dividing of the multigrid method when"coarsen"meshes.

本文将一种高效、快速求解Laplacc边值问题的数值计算方法——多重网格法引入到求解电子光学旋转对称场分布问题。

Caesar ultimately introduced cockfighting into England.

凯撒最终引入英国斗鸡。

On the early days of planting vegetation,we advise that the sanitary landfills introduce green bristlegrass,fat hen and cockspur grass at the same time of sodding.On the latter days,they can plant some good shrubberies to hold the soil of the slope.

建议在卫生填埋场植被建设初期，在种植人工草皮的同时，适当地引入狗尾草、稗草、灰菜等野生优势种，使野生草本群落逐渐替代人工草坪；在植被建设中后期，种植适量抗性强的优良灌木树种，以提高填埋场植被的物种多样性，增加坡面景观效果，发挥植被护坡固土的生态功能。

Codification in other countries has often been associated with the unification of law in the state and the introduction of Roman law.

在其他国家，法律编纂往往同国家的法律统一以及罗马法的引入联系在一起。

In determine the coefficient of drag, the group piles drag coefficient curves are obtained through channel experiment and the conclusion is put into numerical model for simulating several engineering condition .

本文从水流的基本控制方程出发，对经典的N～S方程进行应用，引入阻力项以更好的反映群桩阻力对水流的影响。

In babies, the symptoms of coeliac disease first appear soon after cereals are introduced into the diet.

在婴儿，症状腹腔疾病首先出现后不久，谷物引入到的饮食习惯。

At last,we give the definition of FGT rings which is the extension of cogenerator rings.

在第二章中，我们由FGT -内射模的启发引入了CT -内射模的概念，在这一章我们知道ann -自内射环其实就是CT -内射环，只是ann -自内射环是从零化子的角度来讨论，而CT -内射是从循环无挠模的角度来进行讨论的，同时也给出了一些等价条件。

The injective rings play an important role in the study of rings and categories of modules . First , we introduce the notion of ann-injective rings and CT-injective modules .Second,we make an inquiry into a series of their properties.Third,we give the definition of homological dimension of CT-injective modules.At last,we give the definition of FGT rings which is the extension of cogenerator rings.

本文对环与模范畴中一重要的模类—内射模进行了延拓，引入了ann -自内射环以及CT -内射模的概念，探讨了它们一系列的性质，并定义了CT -内射模的同调维数，最后对余生成子环进行推广得到了FGT -环，讨论了它与CT -内射环的关系以及它的一些性质。

And we prove that the all n-th completely bounded cohomology group H_~n of S with cofficients in B are trivial.

第三章我们引入了局部G-导子的概念，并给出了一个主要结果。

The hydroxyl groups were introduced to the surface of silicone rubber by O_2 cold plasma treatment,coatings made from chitosan were chemically bonded to silicone rubber via silane-glutaraldehyde molecules and proved by the results of surface composites analysis with X-ray photoelectron spectroscopy and attenuated total reflection fourier transform infrared spectroscopy.

用氧低温等离子体处理硅橡胶，在其表面引入羟基，然后利用硅烷偶联剂的硅烷反应，通过中间物戊二醛在硅橡胶表面制备了几丁聚糖涂层。X射线光电子能谱和衰减全反射傅立叶变换红外光谱测试证实在硅橡胶表面成功制备了几丁聚糖涂层，表面接触角测试表明几丁聚糖涂层明显提高了硅橡胶的亲水性

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
