理论上

Power-law fluid is used to describe the Non-newtonian rheological property of the produced fluid in a polymer-driving well; the governing equations, boundary and initial equations of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially is established in bipolar coordinates system; formulas of instantaneous flow rate and stress distribution on the outwall of the inner cylinder of the unsteady flow of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially are established.

在理论上，用幂律流体模型描述了聚合物驱油井产出液的非Newton流变性；建立了双极坐标系下幂律流体在内管做轴向往复运动的偏心环空中非定常流的控制方程及边界条件和初始条件方程；建立了双极坐标系下幂律流体在内管做轴向往复运动的偏心环空中流动时瞬时流量和流体在内管壁上的压力分布计算公式。

In part two, we present a theoretical investigation on the thickness dependence of the exchange bias and the coercivity in FM and AFM bilayer systems, in which the exchange coupling at the interface includes both the bilinear and biquadratic terms.

在第二部分里，我们在理论上解析地给出铁磁和反铁磁双层膜系统的交换偏置和矫顽场随铁磁层、反铁磁层厚度的关系式，其界面耦合包含二次、双二次耦合，铁磁层、反铁磁层厚度均有限。

In theory, it can have an unlimited bit depth, that is, each sample point 1-8-bit, 24-bit, 32-bit or 48-bit.

在理论上它能够有无限位深，即：每样本点1-8位、 24位、32位或48位。

Additional, milk is done not have commonly excitant, but it is better in the bright grandma of 30% to still suggest to use chroma; Yoghurt is in theoretic also have the effect that studies blain really.

另外，牛奶一般没有刺激性，但还是建议用浓度在30%的鲜奶比较好；酸奶在理论上也确实有治痘的功效。

If you put your mind to it, it is quite difficult, even in theory, to think of a circumstance in which the eurozone would blow apart.

如果你仔细想想，即使实在理论上，也很难想象欧元区会四分五裂。

Combustion of pulverized coal is simulated step by step. The simulation result in the blowpipe is used as the input of the raceway calculation. The way of simulations for the blowpipe and raceway is considered more close to practice. By using this model it is possible to improve the simulation accuracy.

第五章根据高炉喷吹煤粉燃烧特点，提出了煤粉在直吹管和风口回旋区的煤粉运动、热解、燃烧的联合数学模型，用此模型可以计算出高炉直吹管和回旋区内煤粉温度场、速度场、氧浓度场和煤粉的燃烧率，从而可对喷吹效果在理论上作出评价。

In principle, embryonic stem cells can differentiate into any type of cell in the body.

从理论上讲，胚胎干细胞可以转化成为人体内的任何一种细胞。

Giraffe A: Technically... a traditional witch doctor has a bone to his nose.

理论上说，一个传统的巫医通常都有根骨头穿过鼻子。

"In theory, any two plants that are closely related botanically and that have a continuous cambium can be grafted."

理论上，两个近缘的并有连续的形成层的植株均能进行嫁接。

In theory, the moral code of Buddhism was little more than a copy of that of Brahminism.

从理论上讲，道德准则的佛教是多一份的

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。
