本文提出了一种引入非定常因素的设计思想，即这样来设计叶型，使尾迹非定常扫掠过程中出现的最严重的扩压过程不发生气流分离。

Species richness and Pielou evenness index were used to measure species diversity. Species richness in polluted area was 32-67, while in control area it was 47-82. Pielou evenness index of tree layer was 0.1161-0.8509, while those of shrub layer and herb layer were 0.1763-0.3249 and 0.0443-0.2601, respectively. The results showed that both species richness and Pielou evenness index were influenced by the point source pollution. Species importance values showed significant differences between polluted area and control area. Dominance of different species had changed, and some species even disappeared under the pressure of pollution, indicating a process of species replacement in plant communities. Such species replacement can provide a scientific basis for species selection for restoration of human-damaged ecosystem. The natural regeneration of Quercus variabilis was insensitive to pollution, while Cupressus funebris was effected seriously.

仅在污染区中出现的物种数量远低于仅在对照区中出现的物种数量；(2)可分出4种基本的群落类型：马尾松林、柏木林、栓皮栎林和马尾松＋栓皮栎林，各群落特定层次的物种丰富度指数以及Pielou均匀度指数在污染区与对照区之间存在显著差异；(3)污染胁迫下，物种在群落中的生态优势度发生了变化，反映了群落中不同物种相互替代的过程，这种物种的替代可为今后受损生态系统人为恢复过程中物种的筛选提供一定的理论参考；(4)对群落中王要物种更新的调查发现：栓皮栎林对污染不敏感；柏木林污染区与对照区幼苗数量及分布格局均有明显差异，污染条件下群落未来演替受到严重干扰。

On the assumption that the boiling point is changing sequentially in the distillation progress, the Engler distillation curve is simulated a function of temperature, and the vapor pressure of liquid paraffin is a function of temperature and ratio of carrying out.

假设石蜡油在连续蒸出时，沸点连续变化，将恩氏曲线回归成函数，液体石蜡油的蒸汽压可以看成是温度和带出量的函数，利用烃类特性因数、沸点与蒸汽压的关系计算机迭代求解，计算可得到设定温度下的石蜡油不同馏出体积比时的蒸汽压。

Followingly, an interfacial acoustic pressure level at a certain point on the vibrating plate is found with this equation.

以脉动半球声源和固定圆板的一阶振型假设为基本物理模型，导出了不同频率下的振声转换公式，由此求出振动板上某一点处的界面声压级。

People were noticing a significant decline in returns on their stock portfolios," Harmel says."I can't point to iStockphoto and say it's the culprit, but it has definitely put downward pressure on prices.

人们发现他们的库存图片收入大大减少，&马克说，&我无法把这归罪于 iStockphoto，但它的确给价格造成了压力。

This doesn't matter from the point of view of the charity; indeed, if people give money more through peer pressure than big heartedness they are likely to dig deeper and more often, which is a good thing.

从慈善的角度来看，这无所谓；实际上，如果人们拿钱出来更多是出于同仁的压力而不是因为大方，他们倒有可能捐得更多、更频繁，这是好事。

This doesn't matter from the point of view of the charity; indeed, if people give money more through peer pressure than big heartedness they are likely to dig deeper and more often, which is a good thing.

第一条是，它必须有点伤筋动骨——给一点对你无关痛痒的东西不算。

On base of analysis to simulation result, it was point out the main cause making dissimilar metal"s bonding so difficult was metal"s inharmonic plastic deformation. The distribution and changement of stress and strain on interface and in workpieces were analyzed.Making use of experiment and simulation result, main factors that influence welding property of cold pressure welding were discussed.
