两对

Through the reverse transformation of dog and wolf, the two novels exhibit the two contrary results: Buck's return to nature is to challenge human civilization, indicating that the anthropocentrism dissolves while White Fang's going back to society is to reward the ecological justice of human being.

两部小说通过狗狼的反向流变展现了不同的人与自然关系所产生的两种截然相反的结果：巴克野性的回归是对人类文明的挑战，预示着&人类中心主义&的解体；而白牙野性的感化是对人类生态正义的回报。

This paper proposes that the antagonistic relations between the two views parallel the debate between behaviourism and constructivism in mathematics education through the analyses of its philosophical position, and shows that philosophy of mathematics has important influences on the actual activity.

基础主义和拟经验主义是数学哲学的两个主要派别，通过对其哲学立场的分析提出这两种哲学观的对立表现在数学教育中就是行为主义和建构主义的对立，从一个侧面表明数学哲学对实际数学活动的影响。

The protocol of this research would be carried out as follows: to evulate effects of sodium ferulate on experimental colitis model of rats induced by acetic acid and investigate its mechanism; to evulate effects of sodium ferulate on experimental colitis model of rats induced by trinitrobenzene sulfonic acid with ethanol and investigate its mechanism.

我们在建立乙酸、三硝基苯磺酸(2，4，6-trinitrobenzene sulfonic acid，TNBS)两种经典大鼠结肠炎模型的基础上，采用灌肠给药方式来观察阿魏酸钠对这两种大鼠实验性结肠炎的作用效果，进而从不同角度对其有关机制进行探讨，以期为阿魏酸钠成为IBD有效治疗药物的开发应用提供实验依据。

In the second chapter, we discuss the depletion interaction between two big hard spheres under the symmetrical geometry confinement. The depletion interactions under the unsymmetrical geometry confinements are studied in the third chapter. The second and the third chapter involve the author s original works.

第二章主要讨论了在对称的几何约束下两大胶球间的排空作用；第三章主要研究了非对称几何约束下两大胶球间的排空作用和同样约束下旁系大胶球对大胶球与硬板之间排空作用的影响；第四章简短地总结了本文的工作，并对以后的工作提出了一些展望。

To investigate the pressure drop due to the friction between gas-solid suspension and CFB riser wall and its effect on the measurement of average solids holdups by pressure transducers,models for predicting the pressure drop and the solids holdup were developed.

为确定气固提升管充分发展段的摩擦压降及其对颗粒浓度测试的影响，提出了充分发展段内气固两相流与管壁间摩擦压力降的计算模型，由此获得充分发展段内真实颗粒浓度的计算公式；同时在两套提升管实验装置上对压力梯度分布和局部颗粒浓度进行了系统测试和对比分析。

由于这两种任务只对中央执行系统产生干扰，对其他两个子系统不产生影响，因而能有效地分离工作记忆各子系统的功能，使研究更有效。

Then compare the5 drafts from these aspects such as reliability, flexibility andeconomy, and keep two more reasonable plans than others. The shortcircuit current calculation is carried on.. And main electricequipments including circuit breakers、disconnectors、bus、insulatoretc are choosed according to the result of short circuit currentcalculation. Finally the economy of these two plans are comparedand main electrical connection plan is determined.

然后对这五种方案进行可靠性、灵活性和经济性比较后，保留两种较合理的方案，对这两种方案进行短路电流计算；接着是根据短路电流计算结果进行主要电气设备的选型以及校验，包括断路器、隔离开关、母线、绝缘子等；最后再由经济性比较确定最终的电气主接线方案。

So obsessed with their own specialisms that they particularly could not tolerate views different from their own and refused to be assimilated."Attacks" occurred in succession.

两个人都对自己的专攻很痴情，很虔诚，因之对&异学&就格外地不能容忍，拒绝同化，于是，两个人的&互相攻击&现象也就从不间断。

A three dimensional Navier Stokes equation is solved with a standard k ε turbulent model. Two experiments were carried out and the total pressure of jet flow was tested. Based on the tests, the differences between the calculated and test results were found to be 3% and 7% respectively. It proved that the results of calculation can well be used in engin...

研究采用数值计算和试验测量相结合的方法，控制方程为三维、雷诺平均 Navier- Stokes方程及 k-ε二方程的紊流模型，并且对该发动机进行了燃气流场的测试，对流场中的总压强进行了直接测量，进行了两次试验；在两次测点位置，试验结果与数值计算值相差分别为 3%和 7%；证明了对双喷管火箭燃气射流流场的数值计算具有了较好的精度，计算模拟结果可以用于工程设计中

Ejector seat levers come in two basic varieties: those that cause a significant visual dislocation (large changes in the layout of tools and work areas) in the program and those that perform some irreversible action .

弹射座椅操作杆有两个基本变形，即造成视觉分布上（对工作区和工具排列的巨大改变）重要变化的行动和造成一些不可逆改变的行动，这两类功能都应该对经验较浅的用户是隐藏的，其中后一个更危险。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
