It indicates that emphasis should be put on the following subjects in the future: the determination of field infiltration coefficient and roughness coefficient;the optimal combination of field standard and irrigation technical index ,and the rational ground levelness degree and mode.

对近10多年来地面灌溉水流运动数值模拟方面的国内外研究进展进行了归类整理，并就目前研究中存在的不足和未来急待深入研究的问题进行了探讨，认为在今后的研究中应把地面灌溉入渗参数和糙率的确定问题，不同地区和作物条件下合理的田块尺寸与灌水要素的优化组合研究及经济合理的田间土地平整度及平地模式的研究，长畦分段灌、阶式水平畦灌、覆膜灌溉条件下的水流运动和合理灌水技术指标的研究，浑水灌溉和土壤气阻对地面灌溉水流运动的影响机理研究等作为重点内容。

Taking HPAM solutions as an example, the unsteady flow of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially is calculated; the distribution of velocity, flow rate and stability parameter is obtained; taking HEC solutions as another example, the flow of second order fluid in eccentric annuli with the inner cylinder moving axially is calculated too; the distribution of velocity and stress is obtained; the effect of eccentricity and axial movement on stress distribution on the outwall of the inner cylinder is analysed.

在理论上，分别用二阶流体和幂律流体模型描述聚合物驱油井产出液的非Newton流变性；分别建立了双极坐标系下二阶流体和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；建立了幂律流体在内管做轴向往复运动的偏心环空中流动的稳定性参数和流体在内管壁上的压力分布计算公式；建立了二阶流体在内管做轴向运动的偏心环空中流动的流体在内管壁上的压力分布计算公式。

The theoretical and computational results show that an important reason resulting in eccentric wear of the inner cylinder and the pumping rod lies in the nonuniformity of the stress distribution on the outwall of the inner cylinder which yields excentralization effect of the pumping rod when swabbing fluid flows in eccentric annuli with the pumping rod moving axially in a well.

在实验上，通过不同重量百分比浓度的HPAM水溶液在内管做轴向往复运动的偏心环空中非定常流实验，把由理论公式算得的时间平均流量与实验中测得的时间平均流量做了比较，验证了本文数值计算幂律流体在内管做轴向往复运动的偏心环空中非定常流方法的正确性；上述的理论与计算表明，抽油机井杆管偏磨的一个重要原因是，在聚驱工况下，抽汲液体在抽油杆做轴向运动的井筒中流动时，抽汲液体作用在抽油杆外壁上的压力分布的不均匀性所引起的抽油杆在井筒中的偏心效应。

The pathways that regulate tone are similar to those that regulate voluntary and involuntary motor movements and, as a final common pathway, involve the spinal reflex arc.

控制张力的传导通路和那些控制随意或非随意运动的通路是一样的，即脊髓反射弧，这是一个最后的公共通路：控制肌纤维的α运动神经元位于脊髓前角，发出反射弧的传出纤维，源自肌梭的传入冲动经由Ⅰa纤维传向脊髓，这些直接与α运动神经元连接的轴突中的一部分激活主动肌。

Based on the rigorous analysis of the kinetic process of both primary and secondary electrons, the related surface charges were analyzed, and the energy gain of emitted electrons was proportional to the square of the ratio between the tangential and normal component of electric field. In this process, the image force of mirror charges would result in an energy loss. Meanwhile, the effect of field alternation of power frequency ac voltage on electron movement could be ignored.

在前人工作的基础上，进一步严格推导了场致一次发射电子和二次电子的运动方程，分析了电子发射引起的绝缘材料表面带电，表明电子发射后的能量增益正比于场强的切向与法向分量比值 F /// F ^的二次方；同时考虑了在电子发射和运动过程中电荷镜像力的作用，并探讨了交流电压下表面带电的情形，认为当考虑电荷镜像力的作用时，电子的能量增益可能变小，而工频交流电压下电场交变对电子运动的影响可以忽略。

The universal research in microscopic tribological mechanism of contact, adhesion, friction, molecular-level solid-liquid interaction, tribochemistry, triboelectricity etc, in the interaction among goetmaterials or between goematerials and artificial materials during geomotion, were reviewed and analyzed.

2综述和分析了地质运动过程中普遍存在的微观摩擦机制如接触、粘着、分子级流体-固体相互作用、摩擦化学、摩擦电性等的研究概况，认为地质摩擦学的研究应具有宏观和微观两个层次，对地质运动的微观机制的研究将促进对地质材料的地球物理、化学和力学性质的研究，并有助于对各种尺度上的地质运动过程的理解

Early in the development of the costumes, elaborate costumes is to show status and wealth, to the late 18th century, the British gentleman's dress became the model for all the men dress, because hunting is a sport that people have a vast land, the hunters have Great reputation, the 19th century sportswear limited to hunting, archery, bowling ball recovery, with a modern look at these sports apparel is not functional, but they slow the evolution of the direction is more useful, a symbol of participation in sports People have enough leisure time for entertainment, clothing suitable for strenuous exercise changes become perfectly acceptable to the facts.

在早期的服饰发展中，精巧的服饰主要是为了显示地位和财富，到了18世纪末期，英国的绅士服饰成为了所有男子服饰的样板，因为狩猎运动暗示着一个人拥有广阔的土地，狩猎者有巨大的盛誉，19世纪的运动服局限于狩猎、射箭、草地追球，用现代的眼光看这些运动服装显然不具有功能性，但是它们缓慢的进化方向却更为有用，参加体育运动象征着一个人有足够的闲暇时间用于娱乐，适合剧烈运动的服饰变化成为完全可以接受的事实。

There is a great variety of tectonic compounding the basic types of which include the compounding of various structural features, and that between structural features and geological formations as well as that of various geological formations. The compounding structures may be either autochthonous or allochthonous;they may also comprise structural features caused by the same manner of tectonic movements or by different manner of tectonic movements ;and finally ,there may be compounding of structures of all sizes ranging from microscopic ones up to tectonic belts or even tectonic domains.

构造复合存在多种多样的形式，其基本形式不仅包括各种形迹的复合，建造与形迹的复合，而且包括建造与建造的复合；就其复合的空间位置而言，既有原地的复合，也有异地的复合；就运动方式而言，既有同方式运动的复合，也有不同方式运动的复合；就构造复合的规模和等级而言，小至小型或显微构造，中至露头规模的构造形迹复合，大至构造带、构造地块、构造体系乃至巨型构造域的复合。

In brief, a concerted attempt was made to characterize this passage as a condemnation of the hubristic aspirations of movements such as National Socialism that sought a monstrous "greatness" on the basis of a total control of humanity and nature through conquest and technology; the "inner truth" of the movement could then be taken as the historical truth of a phenomenon whose profound, if unsettling, significance defines the nihilism of the times.

概言之，对这段话的解读业已取得一致——其意在谴责诸如国家社会主义之类运动的狂热性，因为此类运动谋求的是一种通过军事征服和技术征服、全面控制人类和自然的、极其恐怖的&伟大性&；此类运动的&内在真理&意指某类现象的历史性真理，其深远的、即便是令人不安的意义在于确診了这个时代的虚无主义病。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
