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。

This rigidness also meant that the Russian Air Force totally neglected air superiority in favor of dedicating everything to tactical air support, but this resulted in its almost total destruction, on the ground and in the air.

这种僵化也体现在苏联空军完全忽视了空中优势在战术上重要性，从而导致它几乎被全部摧毁在机场和空中。

This rigidness also meant that the Russian Air Force totally neglectedair superiority in favor of dedicating everything to tactical airsupport, but this resulted in its almost total destruction, on theground and in the air.

这种僵化也体现在苏联空军完全忽视了空中优势在战术上重要性，从而导致它几乎被全部摧毁在机场和空中。

Based on the radiation characteristic of air speedy object, taking into account the synthetic influence factors of the real configuration of object, sun radiation, space long-wave radiation and the environment radiation around object, a further study for the effect of scarfskin pneumatic heating up, used equivalent resistance to estimate inner heat-resource and gave prominence to the influence on scarfskin radiation caused by engine heat-scattering, a logical and effective IR imaging simulation model for airplane is presented in this paper.

从红外辐射和热传导基本定律出发，综合考虑目标实际结构、太阳辐射、天空长波辐射、气动加热及周围环境辐射等因素的影响，依据空中快速目标热辐射特性，分析气动加热对飞机蒙皮辐射的作用，运用等效热阻对内热源部分进行估算，突出发动机传热部分对飞机整体辐射产生的影响，并建立一种可靠实用的空中飞机红外成像仿真模型，仿真过程中结合对空实拍红外图像进行动态调整，目标模拟结果真实感较强。

In the class, the professor taught the students how to use an adverb in the sentence.
