理论上

It's theoretically possible that John Barrowman isn't the busiest entertainerin the world, but there is simply no way he isn't the busiest gay entertainer zipping around theplanet.

理论上来说 JB有可能不是世界上最忙的艺人，但是毫无疑问，他肯定是整个地球上最活跃的gay艺人了！

However,authors still do not find the relevant references on convergence and symmetric problems of the semi-analytical solution.Based on the semi-analytical solution for Hamilton canonical equation theory,the formulations of the clamp and simply supported and symmetric boundary conditions on the Hamiltonian element are derived by the variational principle.Several numerical examples show that with increase of meshes,the convergence rate of the semi-analytical solution is faster than the convergent rate of traditional finite element method based on displacement.

①在厚度上没有任何位移和应力模式的假设，由于传递矩阵方法的引入，从理论上讲，不受板壳厚度或层合板壳层数的限制；②采用弹性力学的Hamilton正则方程半解析法，可以克服边界的局部化效应[8]；③由于在平面内或圆柱壳的曲面内采用了有限元法，所以一般的板壳问题不受结构侧面边界条件的限制，在复杂工程板壳问题上具有广泛的应用领域。

Properties of efficient portfolios and the efficient frontier to the model are systematically analyzed. Our main results concerning the properties are: every efficient portfolio can be solved by minimizing portfolio risk under a given level of portfolio return or by maximizing portfolio return under a given level of portfolio risk; on the efficient frontier, the risk is a convex and strictly increasing function of the return and the return is a concave and strictly increasing function of the risk; the utility function on the efficient frontier can be expressed as a quasi-concave function of the risk or the return if the investor's utility function is quasi-concave.

从理论上系统地对该模型下的有效投资组合和有效前沿的性质进行了分析，结果表明：每一个有效投资组合可通过在给定期望收益水平的条件下最小化投资组合风险来获得，或者在给定风险水平的条件下最大化期望投资组合收益来获得；在有效前沿上，风险是收益的严格单调递增凸函数，收益是风险的严格单调递增凹函数；当投资者的效用函数是拟凹函数时，则有效前沿上的效用可表达成风险或收益的拟凹函数。

In part three, the author describes the present situation of the system of counterclaim in our country and analyses the reasons for that.

第三章反诉制度在我国的适用现状及原因分析，在这一部分，笔者从立法上、司法上、理论上三个方面介绍反诉制度在我具体适用的现状及存在的问题，并相应的从这三个方面探究反诉制度在我国适用受阻的原因。

The stock pricing is the focus on the stock market research, it can solve the value centrums of Chinese stock market, provide the support or counterevidence in theory for market supervision, and it also can solve of the problem of irrational investing.

股票市场的定价问题是证券市场研究的焦点问题，其研究的重要意义不仅可在宏观上能解决中国股市的价值中枢，给市场监管提供理论上的支持或反证，另一方面也可从微观层面上解决投资者投资盲从的问题，在当前证券市场持续低迷，可持续发展陷入困境，且本土定价权面临丧失的背景下具有重大的现实意义。

In this dissertation we propose a set of fast algorithms for computing the DGFT (Discrete Generalized Fourier Transforms) over the hexagon domains and the parallel dodecahedron domains and give the parallel implementation on Linux clusters.

本文在理论上的主要贡献就是利用多色排序、区域分解和多重网格的思想，设计了二维三方向平行六边形区域和三维四方向平行十二面体区域上广义离散傅立叶变换的快速算法并给出它在PC Linux机群上的并行实现。

The land expropriate cannot eliminate the right to contract for management of land.

在理论上，土地所有权的征收已不能消灭土地上存在的作为独立用益物权的土地承包经营权；在实践上，如不征收补偿土地承包经营权，失地农民的经济状况相比同一集体经济组织的其他成员会显著恶化。

Since 1990s, it has attracted much attention of researchers around the world, and has been well developed and applied. Now, this theory has become a flash point in the research area of computer science and information science.

自上世纪九十年代以来，粗糙集在理论上不断完善，在应用上广泛扩展，已逐渐成为国际学术界的研究热点之一。

Especially in 21~ century, as China entering into "WTO" and the global economy integrative development, the people imperiously need the government to enhance its performance to adapt the new challenges and opportunities brought by "Globalization".

我国在上世纪90年代初开始引入绩效评估的概念并在各级政府中进行实践，无论是在理论上还是实践上发展时间都不长，经验也不足，成果不够明显，存在的问题也很多。

Finally, apply the model to the wave calculation of a project area in northern Jiangsu Province. The results indicate the favorable inosculation with theoretical and practical values. The distribution of wave field is reasonable and basically unanimous with the results of adopting other models on wave calculation, which has proved the correctness of this model in theory and the practicability on engineering.

最后将模型应用于苏北某地的工程区域的波浪计算，计算得到的波浪场分布合理，波浪要素数值上与采用其他波浪模型所得的结果基本一致，说明了本文所建立的模型和计算方法在理论上是正确的，在工程上实用。

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。
