平均时

In 6 A cells tested with Sp 10-4M were also depolarized followed by AP reduction.

幅值为27.1±3.0mV，去极化高峰时，AP消失或减小，膜电导平均降低22.3％。

We found many strongly diffracting features that are much larger than the initial average grain size and are formed immediately in the deformed zone upon straining e.g., the feature marked by a white arrow is about 60 nm in diameter in Fig.

我们发现，许多强烈衍射的功能，远远大于最初的平均晶粒尺寸，并立即成立变形区时紧张（例如，功能特点是白箭约为60纳米，直径图。

The results showed that: at metaphase I, the homoeologous chromosome pairing among different F1 hybrids ranged from 2.0 to 11.4 bi-valents formed by homoeologous chromosomes per pollen mother cell, and very few multivalents, and even very few bivalents were formed by two chromosomes within one genome rather than homoeologous chromosomes in some PMCs; at anaphase I, all biva-lents were disjoined and most univalents were divided.

结果表明在中期I阶段，这些杂种一代的近缘染色体联会变化很大，每个花粉母细胞中二价体形成的数目从平均2个到11.4个不等，甚至在某些花粉母细胞中，还发现极少的多价体和非部分同源染色体所形成的单基因组内二价体；在后期I时，所有的二价体分离，同时多数单价体也分离，分离的二价体和分离的单价体都移向两极，从而形成两组染色体；因为这时完整花粉母细胞中分离的二价体在两组染色体中总是对应出现，从而根据半二价体上染色体重组的位置可以分析在二价体的四分体时期发生在非姊妹染色体之间的多种染色体交换类型，如单交换、三线双交换、四线双交换、四线三交换和四线多交换。

First, it will release significant amount of energy nearly 210x kJ for 1 mol Nx when decomposing. Second, it dissociates into only N_2 which is environmentally friendly.

一方面是由于它分解时可以释放出大量的热量，平均1mol N_x分解可以产生210x kJ的热量。

However, if the amplitude excessed 90%, the mounts of larger bubble increase as the increasing time.

另外，选择惰性气体SF6作为微泡内气体，设计了基于两种非离子表面活性剂（Span 60和Tween 80）的包膜超声造影微泡的膜材料组成，使用声振法制备得到表面活性剂包膜的超声造影微泡；对制备过程中的声振条件进行优化，结果表明总体上振幅越大，处理时间越长，声振后溶液的总体积增加得越多，即产生的微泡量越大，并且平均粒径越小，但当声振幅度增大到90%时，随着声振时间的延长，主要增加的是大微泡的量，有效微泡的量无明显增加，因此最佳的声振条件选择为振幅90%，声振时间60s。

Hemangiomas reach 80% of their maximum size by a mean age of 3 months.

血管瘤体积在平均月龄3个月时可达最大体积的80%。

Simulation results show that the new algorithm can keep an average path length similar to Chord while the length of routing tables maintained by most nodes are reduced remarkably(the length is reduced by 31% when the Chord ring is divided into 5 groups).

仿真实验表明，新算法能够保持与Chord接近的平均跳数，而大部分节点的路由表长度却可以得到显著地减小(如Chord环被分为5组时路由表长度减少了31%)。

As for the importance of the distribution of the solutions on the Pareto front, the following measures are introduced in the dissertation: the Niching technique for keeping the genetic diversity and the real coding combining with the average crossover operator for eliminating the so-called"ending effect"of the GAs coding.

求解Pareto波阵面时，解的分布性至关重要，本文从两个角度来提高解的分布性：一是采用小生境技术解决了基因材料多样性损失问题；二是采用常规实数编码配合平均交叉算子解决了端点效应问题。

The content of SF in this polymerizing system does not affect the rates of the said homopolymerization and copolymerization,but causes a drastic change of the average molecular weights of the polyacry...

聚合体系中SF的含量在一定范围内变化时，对AN均聚和AN-MA-SMAS共聚的反应速度均无影响，但引起聚丙烯腈和丙烯腈共聚物的平均分子量的急剧变化。

Where an enterprise prepays EIT on the monthly or quarterly basis under Article 54 of the EIT Law, it shall make the prepayment in line with its monthly or quarterly actual profits. Where it is difficult for it to make prepayment based on its monthly or quarterly actual profits, it may make the prepayment based on the monthly or quarterly average of the amount of tax of the preceding tax year, or make the prepayment by any other means acceptable to the tax authority.

企业根据企业所得税法第五十四条规定分月或者分季预缴企业所得税时，应当按照月度或者季度的实际利润额预缴；按照月度或者季度的实际利润额预缴有困难的，可以按照上一纳税年度应纳税所得额的月度或者季度平均额预缴，或者按照经税务机关认可的其他方法预缴。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
