查询词典 for a change

To control speeds for a typical alternating current motor we usually take control variables (to change voltage and frequency of the stator power supply) from the stator side in an electric motor which is also the only way for squirrel-cage asynchronous motor with rotor in a short-circuit state.

对于一般交流电动机的调速，我们都是从电动机的定子侧引入控制变量（改变定子供电电压、频率）来实现的，这对于转子处于短路状态的交。。。

In this paper we have studied the Upper bound for the time derivative of information entropy for a dynamical system driven by colored cross-correlated colored noises. The Fokker-Planck equation was obtained by using the unified colored noise approximation. The upper bound for the rate of entropy change can be calculated explicitly based on the definition of Shannon's information entropy and the Schwartz inequality principle.

" T！ z2 r" j0 S0 F5 J* T 摘要：本文研究了一种由色关联乘性和加性色噪声驱动的随机耗散动力学系统随时间演化的熵变化率上界，通过统一色噪声近似方法给出了该系统的近似Fokker-Planck方程，然后结合Shannon信息熵的定义及Schwartz不等式原理给出了该系统经近似后熵变化率上界随时间演化的精确表达式。

At Copenhagen, Tim Groser, the minister for climate-change negotiations and a pragmatic former trade diplomat, pushed strongly for a "global alliance" to research ways of reducing agricultural green house-gas emissions.

To understand the mechanism of mucosal immune response, indirect immunostaining with Staphylococal protein A-Horseradish peroxidase was employed for the study of distribution, change of quantity and rule of increasing or reducing of immunoglobulin A-secreting cells in Harderian Gland, providing theoretical basis for prevention and control of avian disease.

本研究采用改良硫酸铵盐析法、Macro-prep High Q阴离子交换柱层析纯化得到鸡分泌型免疫球蛋白A，免疫家免制备兔抗鸡SIgA多克隆抗体。

The results of the simulation showed that the GMI ratio for a sandwich structured film sandwiching high conductive metal layer was several times lager than that for a monofilm, and the maximum impedance change ratio occurred at the frequency of about 10 MHz which was lower than that of single layer film.

模拟的结果表明，中间夹高导电性材料的F/M/F型三明治薄膜的巨磁阻抗效应比同样厚度的单层磁性薄膜的巨磁阻抗效应要大很多，而且三明治薄膜出现阻抗最大变化时的频率大概在10MHz左右，比单层薄膜要低得多。

"A significant number of plastic surgery patients opt for eyelid surgery, forehead lifts and face-lifts not only for rejuvenative reasons, but to change an unattractive facial expression as well," said Dr.

&为了使自己更年轻更漂亮，有相当多的人选择了整形眼睑，提高额头，拉皮面部手术，&研究创始人之一，琼A。

So,for and coming of new term,i made a decision to change any habits which were inappropriate for a good student...however...regretfully...last night i laid down not to sleep but kept unexpectable awake till 3 AM!!!

为了即将到来的开学，我决定改掉所有不适合一个学生的坏习惯……可是……可惜……昨天竟然躺在床上辗转反复夜不能寐直到凌晨3点！！！

The for loop beginning on line 18 contains an if statement that concatenates a pair of strings.These strings do not change throughout the course of the application, yet this calculation must be performed for each loop iteration.

第18行的for循环包含了一个if语句，在这个if里面执行了合并两个字符串的操作，而被合并的这两个字符串从始至终就没变过，我们可以在这里优化一下。

Your last mail made me trouble sleeping whole night Moreover, this suffering order took me for a drowsed weekend After a thorough discussion to those concerned, we finally accept the price of $15 per pair But the payment terms indeed need change to 50% T/T deposit with 50% L/C at sight because we have to pay dearly for raw materials This is the only condition I can give you under your price issue ……Await your early reply

你的上封邮件让我彻夜难眠，这张多灾多难的订单更让我度过了一个昏昏沉沉的周末经过与相关人员仔细商量，我们最终同意你提出的每双15USD的价格但付款方式绝对应该更改为50%的TT订金及50%的即期L/C，因为我们要花很大的成本去购买原材料这是我们在你出的价格下唯一能接受的条件了希望你早日回复

Is it "pavement poetry vibrates with commitment to speaking for the voiceless," as Michael Eric Dyson, a professor at Georgetown University, believes? Is it "an enormously influential agent for social change which must be responsibly and proactively utilised to fight the war on poverty and injustice," as the Hip-Hop Summit Action Network, a pressure group, contends? Or is it mostly "angry, profane and women-hating…music that plays on the worst stereotypes of black people," as Bill Cosby harrumphs?

是否如gerogetown大学的教授michael所言，Hip-hop是&声援弱势群体的路边诗歌&；抑或如压力集团HSAN所认为的那样，Hip-hop具有&巨大的影响力，可以带来社会变革，因此要负责任的、积极的加以利用以抗击贫困和不公正&；还是像bill不屑一顾地认为，Hip-hop&是黑人用来表达愤怒、低俗和仇妇的最糟糕的陈词滥调？&

The split between the two groups can hardly be papered over.
