理论上

So the research of enterprises in the industrial cluster is meaningful not only in theory, but also in practice.

因此，对产业集群企业的研究不仅在理论上而且在实践上都具有重要意义。

Scientists may have theories, but most Pacific islanders believe that the coconut palm is of supernatural origin.

In this paper, we mainly discuss nonparametric and semiparametric functional coefficient quantile regressions, their estimation methods and applications.

半参数变系数分位数回归模型，在理论上其假设前提条件限制比较少，在应用上具有很好的灵活性和很广的适用空间，能够更好地解释现实经济问题。

The correct answer is "when covered by a film of liquid sufficient to reduce the coefficient of static friction between the tire and the road to essentially zero, but not so deep as to introduce a new source of friction."

正确的答案是"当被覆盖上一层液体足以把轮胎和道路之间的静态摩擦系数减少到理论上的零值又不产生新的摩擦源"。

Some points did not only have the positive functions in the cognition of developed capitalist malpractice and in the cognition of the opposite function of modern technology culture,but also suggested some problems,which we have to cogitate about and solve.But he did not concrete...

但是，由于哈贝马斯的科学技术意识形态论并没有具体而科学地考察当代西方社会的生产方式、政治经济制度是如何制约和影响人们的文化心理结构的，相反，他抛开特定的社会背景，片面强调科学技术对理性影响的消极性，将科学技术说成是一种肯定的、排除批判否定精神的思维方式的帮凶，甚至把科学技术直接等同于意识形态，这在理论上是难以成立的，在实践上也是有害的。

Like the Quaestiones, the Courts of Queen''s Bench, Common Pleas, and Exchequer were all theoretical emanations from a higher authority, and each entertained a special class of cases supposed to be committed to it by the fountain of its jurisdiction; but then the Roman Quaestiones were many more than three in number, and it was infinitely less easy to discriminate the acts which fell under the cognisance of each Quaestio, than to distinguish between the provinces of the three Courts in Westminster Hall.

正和"审问处"一样，后座法院（Court of Queen''s Bench）、民事高等法院和理财法院在理论上都是从一个较高的权威分出来的机关，并且每一个机关都分别主管一类特种案件，这类案件被假定是由其管辖权的泉源委托给它的；不过当时罗马"审问处"在数量上远不止三个，如要把分属于每一个"审问处"审判权的各种行为加以区别，远不及把韦斯敏斯德三种法院的范围加以划分那样便当。

From the view of mathematics, it is a NP-hard combinational optimization problem with constraints and it is difficult to find the global optimal solution in theory.

从数学上讲，机组投入问题是一个多约束的NP-hard组合优化问题，很难得到理论上的最优解。

This conclusion shows us produced water from different reservoir must have different contribution properties which has tightly relation with alkyl phenol and organic acid of crude oil which from relevant reservoir. So according to chromatogram fingerprint feature of commingle produced water and single-layer produced water, we can revolve those problems about produced water on theory.

在此基础上我们认为，产自不同油层的水，必定含有与相关油层原油中的烷基酚和有机酸具有密切联系的分布特征，根据单层水色谱指纹特征，混采水的指纹特征，理论上完全可以解决有关产出水的问题。

This device is used in the compensator developed by the authors.

结果表明，这种装置在理论上是正确的，实践上是可行的，已用于研制的补偿装置。

It's no necessary to special the subject of computer crime.

过失构成计算机犯罪在理论上不存在问题，在实践上也有需要。

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。
