离会

Getting exercise will diminish your risk of some of those health disasters you're working up to. Never take an unnecessary step. Spend ten minutes driving round the car park to get a spot as near to the store as possible.

锻炼会将你梦寐以求的疾病拒之门外，没有必要时千万不要选择步行，停车时宁愿花上十分钟找到一个离商店更近一点的停车位。

Sometimes due to pick out the biting too tight, will make the paint coating exuvaite dispqtching of the poor, their adhesion in paint and iron edge sites often include coating tablets of shavings fall off.

有时间由于叼牙咬得太不松，会使涂料零落；有的涂料本身附着力不离不差，在涂料铁的边际部位必然有涂料粒屑不穿着下来。

This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.

首次从三维三波相互作用方程组推导得到了位相畸变光束倍频的小信号解；通过建立国防科学技术人学研究生院学位论文三维数值模型，编写相应仿真程序，首次得到了位相畸变光束倍频过程的大量计算结果，深入细致地研究了位相畸变光束经非线性光学频率变换后谐波的转换效率、光强分布、位相分布以及影响它们的各种因素；得出谐波的远场发散角和光斑二阶矩的变化规律会因为基波像差的不同而不同，但谐波的远场发散角明显地比相应基波的小的结论；得到了在走离效应和衍射效应等影响许多因素可以忽略的情况下，位相畸变传递到二次谐波的估算式；举例分析了KDP三倍频方案中，基波位相畸变对二次谐波和三次谐波的影响；实验工作中，用哈特曼一夏克传感器分别对IO64nm倍频过程和790飞秒超短脉冲倍频过程中的基波和谐波的位相分布进行了测量，给出了相应结果。

The DUPONT Edition, the drying requirements in temperatures of up to 60 ° c for 2 hours bakeout, otherwise there will be a version of culter, non-uniform thickness, elastic and hardness cannot be fully restored, the business card printing and membership card production is known to occur in cases of serious collesting of doubling the edge.

不离DUPONT版而言，其烘干请求在60℃的温度下烘烤2小时，否则不兵会不入现版翘边，厚度不服均，不塑性和不不硬度不克不及合座复兴，制卡和会员卡制作时会不入幻想不天边缘严轻的轻影。

As the material penetrates into the surface and the chemical reaction starts you are already on your way to a hardened, densified, dust proofed floor. This process will continue for several months.

当材料渗入混凝土里面并与混凝土各种成分发生化学反应时，您已经离拥有一个硬化、致密、防尘的优质工业地坪不远了，这个过程将会持续几个月。

In the presence of high concentration of detergent DOC, the higher-order form dissociated to dimers.

此higher-order结构在高浓度清洁剂DOC下，会发生解离，成为dimer型式。

Separation effect and retention time of organic acids could be improved byreducing pH values of the eluent and column temperature.

降低流动相的pH，可有效抑制有机酸分子的解离，延长保留时间，提高有机酸的分离效果，但流动相的pH不应低于2.0，否则会导致色谱柱填料的水解，损坏色谱柱。

I think they would have cheered her had she been a little nearer to us; but, as it was, we ran up our flags in answer to her, adding our position and comparing our chrono- meters, then dipping our ensigns and standing away.

我想，如果快帆船离我们再近一点，他们准会欢呼起来；可是，事实上，我们升船旗对她做出回应，确定了我们的位置，核准了经纬仪，降下了各种色彩旗，然后站开。

When they arrived home, they saw a bird cage hanging under the eves of their house.

这个电影让我幼小的心灵了解到，爱和幸福是必须努力追寻的，追寻以後会发现它离自己其实不远。

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