这点大家深信不疑，最简单的用法是在洗脸水中加入数滴，或者用棉签蘸一点儿柠檬汁直接涂在斑点上，坚持数日，皮肤就会还原往日的白皙了。

The mechanism of oscillation overvoltage and induction overvoltage produced in transformer windings under impulse voltage conditions, the principle of the simulation of impulse voltage distribution in transformer windings, and the experience of winding insulation design using the simulation software are theoretically summarized.

在工频电压和操作电压作用下，电力变压器绕组匝间和饼间的电压差值近似按匝数平均分布。但在雷电冲击作用下，由于电压波形的波前等值频率高达数百千赫兹，绕组匝间和饼间的电容和绕组对地的电容影响已不能忽略。

As a senior American team arrived in Beijing on Sunday for climate talks, the standoff was taking on the trappings of cold-war arms control negotiations, with gigatons of greenhouse gas emissions replacing megatons of nuclear might as a looming risk for people across the globe.

美国资深团队于星期日抵达北京就气候问题参与会谈，在控制冷战武器饰物谈判上呈现和局，紧接着以数十亿顿的温室气体排放物取代数兆吨的核能的提出就像海市蜃楼一样在全球范围内给人类带来危险。

8 Mol/L. The electrode process and reaction mechanism of ACOP were investigated. The results show that the proton numbers is 2 and electron transfer number n is 2. The method has been used to determine the content of ACOP in tablets with the recovery between 98.2%~105.0% by means of standard addition method. Compare with ultraviolet spectrometry, the method is not remarkable difference.

The analyses of theory and results of experiment show that, in the condition of the same north-seeking points, the less position error is, the higher north-seeking precision is; in the condition of the same position error, the more north-seeking points are, the higher north-seeking precision is.

理论分析及实验结果表明，在相同寻北位置数的情况下，转位误差越小寻北精度越高；同时在一定的转位误差时，寻北位置数越多则寻北精度越高。

No matter it is in main structures or secondary structures, the usage of the concrete count is much steres. The material is used in big quantity and its variability is complex, it will influence the security of the structures directly whether the quality of the concrete is good or bad.

不论是在主要结构或者次要结构方面，混凝土的使用动辄就是数十方甚或数百方的计量，在这数量大且变异性复杂的复合材料当中，混凝土的品质优劣会直接影响结构物的安全。

Firstly, the mechanism of heat transfer enhancement by oscillation heat surface is discussed in natural convection scene. For different oscillation amplitude and Rayleigh number, the frequency that the heat transfer rate of oscillation heat surface is higher than non-oscillation condition is found and called critical oscillation frequency. The limitation enhancement of similar physical model is still researched by this study in mixed and forced convection scenes for different amplitude and Grashof number. Generally, that a heat surface subject to a oscillation motion is advantageous to convective heat transfer is a well-known tuition.
