To prevent epidemical disease prevalence caused by microorganisms in indoor air, a study was carried out to investigate the effect of ventilation, peracetic acid and ozonization on microorganisms reduction in the indoor air within a campus. The experimental results indicated that ventilation was an effective measure in reducing indoor air microorganisms with economy and simple operation.

为了防止室内空气微生物导致的传染病发生，对某校园室内的空气进行通风、过氧乙酸和臭氧灭菌降低微生物的实验研究结果表明，通风可以有效地降低室内微生物的浓度，是最为经济和易行的措施；过氧乙酸灭菌效果好，持续时间较长，可在不易实施通风情况下采用过氧乙酸灭菌；臭氧具有迅速杀菌的效果，使用时要与人保持一定距离，最好超出 1m。

The Establishment is a pejorative term to refer to the traditional ruling class elite and the structures of society which they control .

指的是传统的精英等级思想以及他们所掌控的社会，带有轻蔑的意思，常用于在特定制度下不易改变的精英结构

A theory cannot be tested by its realism of assumptions, but on its observable implications and predictive power.

而一个理论的重点并不在於解释其假设中的断言，有时我们甚至连其假设的真确性也不易去验证（这或许是因为人本身的限制所致），我们只可以从其引伸出来的含意和推断能力去验证这个理论。

The common pressure resistance reflectoscope reflector the price expensive is not often easy to carry, therefore we designed the simple portable pressure resistance reflectoscope reflector to test semiconductor device's pressure resistance value, the specific discussion of the core oscillation circuit design process, Integration of the 555 timer gave a detailed analysis.

常见的耐压测试仪往往价格昂贵不易携带，因此我们设计了简单便携式耐压测试仪来测试半导体器件的耐压值，介绍了耐压测试仪的电路组成及原理，具体讨论了其核心部分振荡电路的设计过程，对集成定时器555做了详细的分析。

Our results show that fitting the spectrum of residual function in FT method gives more accurate rCBF than that of the two SVD methods. But FT method takes more computational time to remove recirculation.

实验结果显示争Q用傅立叶转换法，并对残余函数的频谱加以拟合，所得到的rCBF ，较不易产生rCBF低估的现象，但为了去除再循环的部分，则必须花费较多的时间；而奇异值分解法则容易产生rCBF低估的现象。

So it can be avoided that the computation accuracy is lowered and the calculation result is hard to be convergent for the odd state of transformation matrix.The computation accuracy of wavelet Ritz method and wavelet Galerkin method has been improved so the special'microscopic'property could be fully expressed. An effective method is offered also to solve the problem of high stress gradient and some other odd state problems in engineering.

从而避免了由于转换矩阵奇异而造成精度下降且计算结果不易收敛的问题，提升了小波Ritz法和小波Galerkin法的求解精度，使小波分析的"显微"特性得以充分发挥，并为应力大梯度问题和工程奇异问题的有效求解提供了强有力的计算手段。

But lots of those snacks contain saccharine,antiseptic and such as chocolate and peanuts which attract the people a lot.

零食在欧洲在人民的生活当中具有相当重要的位置，因为随带方便，价格便宜，还有多元化的品种，不易过期，所以吸引了许多的人们，但是有很多食物中都包含了，糖精，防腐剂和吸引人的成份例如巧克力，花生，等等。

In small angle X ray scattering , the measurement for particle distribution was used the scattered intensity of the particle himself.

用小角散射测粒度分布，用的是各颗粒自身的散射强度，而实测的强度总包含有干涉部分，不易分开；考虑到在测非晶态的结构中，用的是各个原子散射光之间的干涉效应。
