82 Times as high as the flow rate at the inlet; the velocity profile in the lower region is relatively uniform, and changes at the exit from a parabolic shape towards a plug flow as Re increases; The strong circulating flow in the upper region is very favourable to evaporization of heated fluid because it not only forces all the heated fluid to flow through the liquid surface and, therefore, to evaporate effectively, but also causes a large part of fluid to recirculate to the liquid surface and, therefore, to get a second opportunity of evaporization. In addition, the uniform velocity profile in the lower region is also favourable to crystallizing process.

轴向进料蒸发室进口管侧上方有强烈的循环流存在，循环流流量为进口流量的1.48～1.82倍；循环流下部流速分布较均匀，出口区流速在低Re时为抛物线分布，高Re时接近活塞流；强烈循环流的存在不仅迫使加热流体全部流经液面及其附近进行充分蒸发，而且之后还使相当部分流体再次循环回到液面及附近进行二次蒸发，对蒸发操作十分有利；蒸发室下部流速的均匀分布亦有利于蒸发结晶过程。

A series of mono-, sesqui-, di- and tri-terpenoids with various structural types, which produced by bio- oxidation, hydrogenation, hydrolyzation, esterification and cyclic cleavage toward-limenone, were analyed by GC-MS.

经GC-MS分析发现该两细菌对-柠檬烯有显著的生物催化转化作用，能对底物进行不同程度的氧化、还原、水解、酯化、开环等反应，并产生丰富的系列结构不同的其它萜类化合物：包括单萜、倍半萜、二萜、以及三萜等。

Because of the high magnification camera, we have to extract the laser streak from the obtained images fist, then we can get the line position of laser streak by using Otsu's method , morphology, skeletonization and Hough transform from the images of inspecting object. The system shows a good performance of getting only 5% error to the reconstructed surface of the standard board.

本系统采用放大倍率较大的镜头，因此在取像之后，必须先做雷射条纹形状的萃取，再运用Otsu演算法做二值化运算，搭配型态学影像处理，骨架化与Hough转换，计算雷射线的相隔距离，再透过前述的公式转换待测物体的厚度值。

This separates the magnetosphere's two main compartments: the crown, a round projection that stretches sunwards by about five times the diameter of the Earth, and the tail, which is shaped as its name suggests and runs far into space on the Earth's night time side.

这样也就把磁气圈两个主要部分就被分离开来：一为首部－圆形的凸出部分朝着太阳伸出5倍地球直径的距离；二是尾部－它的形状就像一条尾巴并在地球夜晚时的那一面伸向宇宙空间。

For the past twenty years, the Chinese economy has achieved a growth rate averaging nearly 10 percent per year, resulting in a quintupling of output per person.

过去的二十年里面，中国的经济以每年接近10%的平均速度增长，造成了每个人的生产量翻了5倍。

According to WIND data showed on November 17, which is limited to the sale of shares on the day before the lifting of the ban, South China's car on the exchange rate as high as 32.84 percent and the volume of 78813.05 Million shares, the volume of transactions 3,424,669,900 yuan.

根据风的数据显示，11月17日，这是有限的一天，出售股份前禁令，南中国的就高达32.84倍，体积汇率车取消的78813.05亿股，交易量三十四万二千四百六十六点九九万元。

Acting as an antenna molecule in the supramolecular system, Mg(superscript 2+)-HA remarkably enhances the photoinduced electron transfer efficiency between C60 and an electron donor, N, N-dimethylaniline.

作为超分子体系中的光捕获分子，Mg(上标 2+)-HA能显著地提高C60与N，N-二甲基苯胺的光诱导电子转移反应效率，生成的C60负离子自由基的电子自旋共振光谱信号强度比未加入Mg(上标 2+)-HA时增强了9倍左右。

This dissertation has deeply studied the tashes of the process of producing green laser according to the theory of velocity equation, the theory of second harmonic generation, the theory of fold cavity etc. In the meantime, a new system of green laser has been designed combining the discussion of the characteristics of activation media and doubling frequency crystals.

本文根据速率方程理论、二次谐波产生理论以及折叠腔等方面的理论，对绿光激光产生过程的诸环节进行了理论分析，同时在此基础上，结合对激活介质、倍频晶体特性的讨论，设计了新的绿光激光系统。

The simulation of the bandgap reference using ideal resistents shows that It's precision is 16.6 ppm.The dynamic range of the sensor is increased by 2~N using multi-sample. The FPN is cancelled using CDS. The pipeline ADC has the good tradeoffs of resolution, sample rate and area.

像素阵列的扫描方式使用多采样技术可以提高传感器动态范围2~N倍，相关二次采样技术消除了像素单元之间的固定模式噪声，使用流水线式的模数转换器可以实现好的分辨率、速度和面积等的折衷。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
