The relationship of the aerated water depth and the energy dissipation rate with the step sizes can be obtained theoretically through the equation.

研究表明，前置掺气坎式阶梯溢洪道具有掺气量与掺气浓度宜于控制，底部掺气充分，抗空蚀性能优越，消能率高，适宜于大单宽流量溢洪道等显著特点，可作为进一步推广应用阶梯式溢洪道的理论和试验基础。

实验表明，所设计的前置放大电路可以有效地满足设计要求。

Automatic gain control circuits are implemented to control the preamplifier stages in the AM and FM reception paths.

自动增益控制电路实施控制在AM与FM接收路径的前置阶段。

It was found that because of the difference in component distribution and structure, the tendency that pores furcate and bend was smaller in amorphous precursor than in crystalline precursor, and for the amorphous precursor, the velocity of Al leaching-out and the expanding of specific surface area of catalyst were more sensitive to activation process parameters.

结果发现，由于两者在组元的分布及结构上的差异，非晶态前置体合金在活化过程中形成的微孔发生弯折、分叉的倾向要小于晶态前置体合金，同时前者在活化过程中的抽Al速率、以及所得到的催化剂的比表面积等对活化工艺更为敏感。

To resist multipath and ISI in acoustical communication, a single filter receiving method and a new method, namely preprocessing frequency hopping filtering method, were adopted simultaneously. A controlled preprocessing frequency hopping filter was added before mixing frequencies of signal receiving system to strengthen resistance against multipath and ISI. The method was simulated respectively on two frequency hopping sequences of PN code and increasing sequence.

除了采用以往的单一滤波接收处理方法，本文还采用了一种新的接收处理方法，即前置跳频滤波接收处理方法，与其他方法不同的是在信号接收系统的混频之前增加了可控的前置跳频滤波器，可以增强抗多途和码间串扰能力，并对此方法分别采用PN码和递增序列2种跳频序列进行仿真研究。

It is shown that transmission performance which uses postcompensation is superior to that uses precompensation and it can be concluded that the postcompensation should be used for dispersion compensation in long-haul, high-capacity optical transmission in the case of the nonlinear effects.

对基于RZ的400b／s常规单模光纤传输系统进行了仿真，该系统的色散补偿分别采用前置补偿和后置补偿，结果发现在存在非线性情况下，其色散补偿采用后置补偿的传输性能明显优于采用前置补偿的传输性能。

In this thesis, research on the grammaticalization of relative clauses is extended to the prenominal type typically represented by examples from Chinese which enjoys a privileged status of having a recorded history of over three millennia.

我们的母语汉语历史上所出现的关系从句主要是前置型的，这为我们开展这方面的研究带来了方便。本文将把关系从句的语法化研究推向新的领域，即把主要集中在后置型关系从句上扩展到前置型关系从句上。

The paper analyses the information statuses and textual functions of preposed and left-dislocated themes in Ailing Zhang's novels and short stories. After the analysis, the paper points out the information statuses and textual functions of the leftmost-moved theme of Chinese.

本文以张爱玲小说的对话中存在的前置主位和左移动主位的信息状态和语篇功能为切入点，分析了汉语中的前置主位和左移动主位的信息状态和语篇功能，并与英语进行对比。

However, from reports these mods seem pretty effective in all the preamps in one form or another though i wouldn't do them on anything more than a NAC72 or Nac102 if you want remote, as beyond that you get more value by selling up, buying the cheaper preamp and using the surplus money to mod.

然而，这些器官功能障碍综合征的报告似乎相当的所有前置放大器有效的这种或那种形式，但我不会做任何事情比NAC72或Nac102更多，如果你想远程它们，因为除此之外，你通过出售更多的价值，购买便宜前置放大器和利用剩余的钱国防部。

C or less of saturated compressed air into the dryer of the pre-cooling device, in the pre-cooling device in heat exchange with the ambient air, high temperature air pre-cooling fan part of the heat is taken away, after pre-cooling the compressed air into the to the pre-evaporator refrigeration system with secondary refrigerant vapor heat exchange, allowing the temperature dropped close to the refrigerant evaporation temperature, and flows through the pre-filter to remove large amount of liquid water, oil mist and dust.

小于等于80°C的饱和压缩空气进入干燥机的预冷器，在预冷器中与环境空气进行热交换，高温压缩空气的一部分热量被预冷风机带走，预冷后的压缩空气进入到制冷系统的前置蒸发器，与冷媒蒸气进行二次热交换，使本身温度降到接近于冷媒的蒸发温度，并流经前置过滤器除去大量的液态水，油雾和尘埃。
