查询词典 have an effect on

I hope that this text sheds a new light on some aspects of the Driac theory which to my knowledge have not yet found their way into textbooks, for example, a rigorous treatment of the nonrelativistic limit, the supersymmetric solution of the Coulomb problem and the effect of an anomalous magnetic moment, the asymptotic analysis of relativistic observables on scattering states, some results on magnetic fields, or the super symmetric derivation of solutions of the mKdV equation.

狄拉克方程》序言——翻译对吗？

The effect of initial pH, temperature and N263 concentratio n on extraction of fucoidan was investigated. It has shown that temperature and initial pH of the solutions have no great influences on the extraction of fucoid an, and when N263 concentration is low, an increase in the concentration incre ases the extraction of fucoidan.

对影响萃取褐藻糖胶的水溶液初始pH、温度及N263浓度等因素研究结果表明，N263浓度是影响褐藻糖胶萃取的主要因素，而初始pH、温度等的影响不大。

Thus an unfortunate side effect of China's attempts to cool its domestic economy has been an exploding trade surplus, because import growth has softened while exports have remained robust. In June, China's exports rose by 30.6%, year-on-year, while imports grew by just 15.1%, widening the monthly trade surplus to $9.7 billion.

也就是说，中国企图控制国内经济过热增长的一个不那么令人愉快的后果是，中国的进口贸易额已经平缓下来而出口贸易则一直强健。6月份，中国的出口贸易增长了30.6%，而进口贸易仅增长了15.1%，每月的贸易顺差扩大到97亿美元。

Thus an unfortunate side effect of China's attempts to cool its domestic economy has been an exploding trade surplus, because import growth has softened while exports have remained robust. In June, China's exports rose by 30.6%, year-on-year, while imports grew by just 15.1%, widening the monthly trade surplus to $9.7 billion. The cumulative surplus for 2005 is now nearly $40 billion, more than for the whole of last year.

所以中国对国内经济降温的企图最不幸的一个副作用就是产生一个巨大的贸易盈余，因为进口放缓，而出口依然活跃。6月份，中国出口同比增长30.6%，而进口增长仅为15.1%，月贸易盈余扩大到97亿美元。2005年贸易盈余现在累计可能达400亿美元，比去年全年还多。

This paper has proposed the following explanation for this topic based on Social Couplings by Maturana, a cognitive biology scholar, organic view by Cooley, a symbolic interactionist , and model of a system in equilibrium by Argyle, a social psychologist:(1) the interaction is an act sequence of "hint-choice";(2) All the teacher and students in mathematics classroom have contributed to the formation and modification of consensual domain;(3) consensual domain in mathematics classroom is not an independent reality;(4) teacher and students' perception to consensual domain in mathematics classroom shall guide their behavior;(5) The coupling standard of consensual domain is not fixed for all observers;(6) the effect of mathematics enculturation should be reinterpreted.

本文整合认知生物学学者Maturana的社会耦合理论、符号互动论学者Cooley的有机观，以及社会心理学者Argyle的均衡系统模型，对共识域之本质与功能提出下列解释作为回应：(1)数学教室内的互动是一「暗示—选择」的行为序列；(2)师生皆对数学教室系统共识域之成型与改变有所贡献；(3)数学教室系统内的共识域并非独立於观察者之客观实在；(4)师生个体对数学教室系统共识域的知觉会指引师生的个体行为；(5)观察者描述数学教室共识域的耦合标准有狭义与广义之分；(6)数学文化传承的必然性应予重新解读。

To want to make up this kind of congenital blemish viable way can carry on directly transporting nourishment, namely, impassability over the function conversion of digestive system, impassability lead the blood deliver, but directly make the organization of an outside dew absorbed nourishment, this is outside called a body and transport nourishment on the medical science, good news BE, can carry on the product that this kind of nourishment outside the body transports have already developed success, gum's atrophying is not"incurable sickness" any more and want ～only tooth slot the bone have no quilt complete absorb, all theoretically can pass a gum rebirth, afresh firm loose dynamic tooth, use effect and widespreadly respond good.

要想弥补这种先天性缺陷，可行的办法只能是进行直接的输送营养，即，不通过消化系统的功能转换，不通过血液传输，而是直接让一个外露的组织吸收营养，这在医学上被称为体外输送营养，好消息是，能够进行这种体外营养输送的产品已经研发成功，牙龈萎缩不再是&不治之症&，只要牙槽骨没有被完全吸收，理论上都可以通过牙龈再生，重新牢固松动的牙齿，使用效果普遍反应良好。

People have paid attention to the pollution of soil and water quality caused by using organic arsenic chemistry reagent to prevent and cure apple-tree canker in our apple area, so it has an important purpose to seek a harm-free way for sustaining development of apple. The tests studied the effect of prevention and cure on apple-tree canker with EM mud, EM liquid, 40%'Fumeishen powder' and contrast. The results showed that the EM mud was superior to the EM liquid, 40% 'Fumeishen powder' and contrast. The prevention and cure effects of EM in 2006 and 2007 were 92.7% and 93.5%, while the recurrence rates of canker scars 1.8% and 2.8% respectively. And the healing effect of scar is 50.4%. So, it was considered as a new way to prevent and cure apple-tree canker with EM mud.

中国各苹果主产区果农长期使用有机砷等化学制剂防治腐烂病，对土壤、水质等环境造成的污染已引起人们的关注，寻求无公害的方法防治腐烂病，对苹果业可持续发展具有重要意义；本试验设EM活性菌泥涂抹、EM活性菌液涂抹、40%福美砷可湿性粉剂50倍液刮涂和对照（只刮除腐烂病疤，不涂药）4个处理，三次重复，进行了苹果树腐烂病的防治研究；结果表明，EM活性菌泥在防治效果、病疤复发率和促进病疤愈合效果方面均优于其它处理，其当年和第二年4月的防治效果分别为92.7%、93.5%，病疤复发率分别为1.8%、2.8%，促进病疤愈合效果也最好（50.4%）；因此，作者提出，将EM活性菌融入粘泥载体中制成菌泥，涂抹在腐烂病疤上，以菌治菌，是防治苹果树腐烂病的新途径。

Therefore the high-power microwave devices-- Metal Semiconductor Field Effect Transistors based on GaAs material have received increased attention. The large signal analysis is an attractive topic because it is an important and tough issue.

Adopt an automation to control the labour intensity being able to improve the product efficacy and lighten a worker not only, and have very good economic returns and social benefits on electroplating production line, wielding PLC is that the automation controls , PLC has reliability height can come true , adaptability has communication function , the modularized characteristic of structure broadly on electroplating production line,therefore how to use good PLC to have become the key that the electroplating production line automation controls , use PLC to add up with frequency transformer carrying out autocontrol on electroplating automation production line bridge crane, Having the structure simplicity , the programming going to the lavatory , handling nimbly , using safety , job stability , strong characteristic of reliable and anti-interference ability of function, is one kind of effective autocontrol way , is that electroplating produces the direction realizing high-effect .

在电镀生产线上采用自动化控制不但可以提高产品生产效率和减轻工人的劳动强度，而且有着非常好的经济效益和社会效益，电镀生产线上运用PLC则可以实现自动化控制，PLC具有可靠性高，适应性广，具有通信功能，结构模块化的特点，因此如何使用好PLC成了电镀生产线自动化控制的关键，用PLC辅以变频器对电镀自动生产线行车进行自动控制，具有结构简单、编程方便、操作灵活、使用安全、工作稳定、性能可靠和抗干扰能力强的特点，是一种很有效的自动控制方式，是电镀生产实现高效、低成本、高质量自动化生产的发展方向。

This entirely studies long end effect is by " even the line " Chris Anderson of magazine chief editor puts forward the earliest in the Changweiyiwen October 2004, use descriptive such as the commerce of Yamaxun and website of Netflix and so on and economic mode, still do not have official definition up to now, the most extensive multitude using in the website is SEO personnel, they are being searched a few not be too popular keyword do not look down upon these keywords, the one discharge that decides keyword of dimensions to bring is to exceed likely advocate of the discharge of the keyword, divide up in a few big doors advocate keyword market we should monarch additionally path, searching competition is not so big keyword, spin these keywords like the tail, grow gotten flow what pull more more, besides SEO, in growing end effect to return body to show to wait for network business in B2C, C2C, B2B, product of an unexpected winner is searched in the commodity with intense competition, seek much site, spin the tail, can increase a sale so.

长尾效应这一概念是由《连线》杂志主编Chris Anderson在2004年十月的长尾一文中最早提出，用来描述诸如亚马逊和Netflix之类网站的商业和经济模式，至今尚无正式定义，在网站中应用最广泛的人群是SEO人员，他们在寻找一些不是太热门的次关键词别小看这些关键词，一定规模的次关键词带来的流量是有可能超过主关键词的流量的，在一些大门户瓜分的主关键词市场我们应该另辟蹊径，寻找竞争不是那么大的次关键词，将这些关键词像尾巴一样拉长，拉的越长得到的流量越多，除了SEO外，长尾效应还体现在B2C、C2C、B2B等网商中，在竞争激烈的商品中寻找冷门产品，找多点，把尾巴拉长，这样就能增加销售。
