衰减

From the results it is found that the high-frequency fall-off constants for small and large earthquakes are different.

我们注意到小震和大震的高频衰减常数是不同的。

The results show that, the RF decreases with the increase of gas holdup.

理论研究结果表明，随着持气率的增加，共振频率减小；当持气率较小时，共振频率衰减较快。

First of all , it is seen in Zhang Wei"s long writing that continuous changes occurs with the following era contexts which is shown. First, the gradual desalinization of " earth image " on the space," earth " is not only a creation in Zhang Wei"s novel, but the main source of the poesy of its works. It declines after " September fable ", not only indicating Zhang Wei "s decay of poesy of the novel, but also reflecting the disobeyed pross of light appear contemporary China social urbanization and common customs to . Second, the change of " writing subject projection " in the spiritual meaning, Its characteristic displayed by the reduction of image of spokesman as write thought representation .and on the other side represent" person who want more that resist actively " which also shows contemporary intellectual predicament and adjustment of value. Third, in " changeable and separate characteristics in the stylistics ",It changes " epic body " of" Ancient ship "," body not mythical " to " September fable "," pour out body " of" Bai Hui "" Family "," the discipline spreads the body "of Book of other provinces"," lie body " of" Can not recall the hollyhock ". Its constant changes persuing of recreation and sports, has entered into the different book mode and narration of different class gradually too.

首先，张炜的长篇写作中可以看出一种跟随时代语境而不断发生的变化，这表现在：一是空间上的"大地意象"的渐趋淡化，"大地"不但是张炜小说中的一个创造，而且也是其作品的诗意的主要源泉，它在《九月寓言》之后的衰退，不但表明了张炜小说中诗意的衰减，而同时也反照出当代中国社会城市化和世俗化进程的不可违拗；二是精神意义上的"写作主体投影"的变化，其特征主要表现为作为作家思想代言者的"正面的知识者"形象的弱化，代表其另一面的"积极反抗的多欲者"的凸显，这也显示了当代知识分子价值的困境与调整；三是在"文体上的多变与另类化"，由《古船》的"史诗体"，到《九月寓言》的"神话体"，再到《柏慧》、《家族》的"倾诉体"，《外省书》的"纪传体"，《能不忆蜀葵》的"诳语体"，其文体不断求变，也逐渐走入了异书模式和另类叙述。

Objective To investigate the resistance of the natural housefly population to the chemical insecticides and their natural attenuation trend in the laboratory environment, and to provide the rational for the management of the resistance.

目的 研究家蝇自然种群对化学杀虫剂的抗药性现状及其在实验室环境下抗性自然衰减的变化趋势，为抗性治理提供理论依据。

We also find that the temperature dependence of those interlayercouplingsare considerably enhanced with the decrease of the Hubbard interaction.

我们还发现当Hubbard互作用减弱时，双线性和双二次耦合强度随温度升高的衰减会显著增强。

HupA had no effect on the steady-state inactivation and the recovery of 〓 from inactivation.

HupA使电流衰减过程变得更缓慢，通道不存在完全失活。

Atropine and Carbacol had no effect on the inhibition of 〓 and 〓 by HupA, indicating that the inhibition was unrelated to the cholinergic signaling pathway.

这提示，HupA可能是作为开放阻断剂，堵塞于K通道的开口，HupA通过影响C-型失活机制而使电流衰减的速度变慢了。

HupA reversibly slowed down the decay of 〓, in addition to causing a reduction in its amplitude. So HupA may block the 〓 also as an open channel blocker at the out mouth of the channels.

这提示，HupA可能是作为开放阻断剂，堵塞于K通道的开口，HupA通过影响C-型失活机制而使电流衰减的速度变慢了。

The result indicates that the damping term drastically changes the asymptotic behavior of the hyperbolic equation.

分析结果表明，阻尼项强烈地改变双曲型方程解的渐近行为，强阻尼双曲型方程组的能量E随时间按指数衰减，即E≤Cexp。

The potential is evaluated as a hyperbolic function of the distance from anode.

这时，管壁电位随着离阳极的距离按双曲余弦函数衰减。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
