不平均的

The monthly runoff of all the age classes was proportional to the mean monthly rainfall.

不同龄级径流的月变化规律和降水量一致，降水量大的月份，径流量也大，4—8月的降水量占年总降水量的62.2%，径流量占年总径流量的75.4%，其中Ⅰ、Ⅱ、Ⅲ、Ⅳ龄级在4—8月的平均径流系数分别为0.3784、0.3224、0.2790和0.2634。

The results show that there will be slight decrease of the control efforts when the mean absolute value or the root mean square value of the optimal control force is taken as the maximum designed control force, while the maximum control force of MR damper can be decreased by 85% compared with the maximum optimal control force. The decrease in the designed control force can not only significantly increase the capability of MR dampers, but also reduce the dimension of MR dampers for pratical application in engineering.

研究表明，当设计值取最优控制力的平均绝对值或均方根值时，MR阻尼器的最大控制力比最优控制力的最大值降低了85%，而控制效果降低不多，可以满足对结构的控制要求；降低最大控制力设计值后，不但可以充分发挥MR阻尼器的出力性能，而且可以缩小MR阻尼器的设计尺寸，便于工程应用。

In a survey of several orchards in Benin, Dr van Mele and his colleagues found an average of less than one fruit-fly pupa in each batch of 30 mangoes from trees where worker ants were abundant, but an average of 77 pupae in batches from trees without worker ants.

然尔，那些果树上爬满了工蚁的农民却不受类似的困扰，米勒博士和他的同事们在贝宁数个果园的调研发现，在那些布满工蚁的树上，每批次30个芒果中的果蝇蛹平均数量不足一个，而在没有工蚁的树上，这一数量为77。

It is good at both high resistance and low resistance area of debris flows. It is good consistent for the measuring velocity of otherwise field observation data of debris flow and viscous mudflow by this empirical equation.

由一系列野外观测资料得到的由泥石流不均匀系数、泥石流运动底部纵比降和水力半径计算的粘性泥石流运动平均速度经验公式，能适应各种类型的泥石流沟，与其它系列的观测资料对比有很好的一致性，与粘性泥流的观测资料对比也很接近。

By a series field observation data, an empirical equation of mean velocity of viscous debris flow was got. The velocity calculated by the asymmetric coefficients, bottom slope and hydraulic radius of flow. It is good at both high resistance and low resistance area of debris flows. It is good consistent for the measuring velocity of otherwise field observation data of debris flow and viscous mudflow by this empirical equation.

Based on the mutual inductance,a technical scheme to change the parameters of asymmetrical phase windings was proposed.

通过引入互感的方法可以定量计算磁链的减小量，并给出了互感计算式，利用有限元法分析了一台样机互感随转子位置和电流的变化规律，理论推导了互感对平均转矩影响的程度，研究了四相8/6极开关磁阻电动机稳态转矩波形在两种绕组连接方式下的不规则特性，结合互感特性，提出了改变不对称相绕组参数的技术方案。

There are many ways that a mutualist may affect a predator-prey interaction, but here we consider just one of these, we consider cases in which a mutualist modifies predation to the benefit of the prey, namely a mutualist deterring predation on a prey.

互助者的介入对捕食-食饵系统可能产生各种各样的影响，这里，我们所考虑的只是其中的一种情况：互助者的存在对捕食者有威慑作用，从而不利于其对食饵种群的捕获，同时，食饵种群的存在又可以提高互助者的平均增长率。

Engine, this paper found out that the antigalling abilities for parts being tested although quite smooth, even with quenched and ground surfaces were not too high, while the antigalling abilities were quite higher for those surfaces more rougher than the former but possess fairly big negative contour skewness RSK and considerable large mean spacing Sm of profile micro-inequality.

本文通过SRV 试验、Timken 试验和发动机挺杆的台架试验，发现了试件尽管很光滑，甚至是淬硬后精磨的表面的抗擦伤能力并不高，而粗糙度比前者高，但具有相当大的负轮廓偏斜度Rsk ，且具有相当大的轮廓微观不平度平均间距Sm 的表面具有较高的抗擦伤能力，这是由于它们具有较好支承面及众多"微油池"有利于润滑的结果。

It is estimated that the lifetime dose of radioactivity to which a person eating irradiated food could be exposed could realistically amount to no more than one-millionth of the recognised limit of average exposure of an individual to radioactivity from other sources over the same period.

据估计，人们由于吃进辐射食物所遭受的放射剂量，实际上不多于同一时期一个人平均可能遭受到的来自其它放射源的、可觉察的放射的极限的百万份之一。

The lifetime dose of radioactivity to which a person eating irradiated food could be expose d could realistically amount to one-millionth of the recognised limit of average exposure of an individual to radioactivity from other source over the same period.

人们由于吃进辐照食物所遭受的放射剂量，实际上不多于同一时期一个人平均可能遭受到的来自其它放射源的放射的可觉察的极限的百万份之一。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
