On one hand, it changes the distribution of meridional wind, thus the geostrophic vortivity develops in the ridge region on the south of the subtropical high at 500 hPa. On the other hand, it causes inhomogeneity of the vertical distribution of diabetic heating, triggering anomalous cyclonic circulation between two ridges and anticyclonic circulation in the ridge region on the south.

这一方面改变了经向风的分布，使500 hPa副高南侧脊线区域地转涡度平流项发展；另一方面引起非绝热加热垂直分布不均匀，在两脊线之间诱生一异常气旋性环流，在南侧脊线区生成异常反气旋环流。

It shows the cause and expression of the Dongpo"s broad-minded outlook on life; it also analyses the technique of expression and aesthetic effect of Dongpo"s broad-minded style of ci. Finally, it explains that all kinds of writers broad-mindedness shares general characters during Song Dynasty, but authors differs from each other in the degree of the broad-mindedness. It is said that only those who are as broad-minded as Dongpo can write ci like Dingpo.

指出东坡旷达人生观的成因及表现；分析东坡清旷词风的表现形式和审美效果；最后说明"旷"在宋代具有共时性特点，但不同士子"旷"的向度不同，"有东坡之心胸，始可为东坡之词。"

Therefore, the moist potential vorticity analysis associated with the mesoscale convective system was researched in the paper, so as to reveal the moist potential characteristics of mesoscale convective system in typhoon circulation. The results showed that, during the generation stage, convective instability characterized by MPV1 was a favorable condition for forming MCS, while the vorticity which was caused by the slantwise isentropic surface and the vertical shear of the horizontal wind characterized by MPV2 was an inspiring mechanism. The specific process was that, the atmosphere exhibited the feature of strong convective instability at the low level of convection areas and the southeast areas, which included plenty of erratic energy. The slantwise ascended the stream transfer the erratic energy to northwest, where the stratification stability was small. As decreased, the cyclonic vorticity increased. On the other hand, the vorticity caused by the slantwise isentropic surface and the vertical shear of the horizontal wind inspired the release of convective instability and as a result that the MCS formed. During the development stage, the cyclonic vorticity increased quickly with the persistent decreasing of . Meanwhile, the inclination of isentropic linewas bigger than the absolute momentum line at middle level, which exhibited the feature of conditional symmetric instability , then the conditional symmetric instability was forced to release by the vorticity resulted from the slantwise isentropic surface and the vertical shear of horizontal wind, and the MCS developed.

结果表明，在对流形成阶段，MPV1即对流不稳定为MCS的形成提供背景不稳定条件，由MPV2即湿等熵面的倾斜和水平风的垂直切变而引起的涡旋发展作为强迫机制：MCS形成的区域及东南区域中低层是强对流不稳定层，蕴含丰富的不稳定能量，倾斜上升运动把对流不稳定区具有强不稳定能量的暖湿空气向西北中层的中性层结区输送，由于的减小，气旋性涡度增强，有利于形成对流，另一方面，由于湿等熵面倾斜和低空急流加强而引起的涡旋发展作为一种强迫机制激发对流不稳定能量得到释放，从而形成对流；在对流系统地发展阶段，由于低层的对流不稳定性进一步减弱，进一步减小，气旋性涡度进一步增强，有利于MCS的增强，中层等θe 线的倾斜度比绝对动量M 等值线的倾斜度大，对应有条件对称不稳定区域，满足条件对称不稳定条件，在湿等熵面倾斜和台风低空急流作用下引起的涡旋发展强迫对称不稳定能量释放，从而使得对流得以维持和加强。

A theoretical analysis shows that the non-zonation of ACC in the region of Kerguelen Plateau is due to the changes in potential vorticity of the water column caused by the curl of the ratio of wind stress to topography. The bifurcation and turning of ACC is related to the curl distribution.

理论分析表明，凯尔盖朗海台区ACC的非纬向性主要是由风应力和海底地形的变化造成的，它通过该海台时的南北路径的分叉和转向与该海区风应力与水深之比的旋度的分布相吻合。

In granularity characteristic of sediment, after typhoon attacking, beach sediment incline to coarse, gravel content added, but part beach sediment show fine, sediment sorting becomes worse, skewness value minished, skewness changes to negative skewness direction, kurtosis value increased, the curves of sediment frequency distributing display double apices.

在沉积物粒度特征上，风后海滩沉积物以粗化现象为主，砾石含量增加，部分海滩沉积物出现细化现象，沉积物分选性变差，偏态值减小，偏态向负偏方向变化，峰态值增加，风后沉积物频率分布曲线多双峰分布。

The results showed that the upper section of the profile contains more coarse fractions and loessic fractions, with the presence of gravels, showing vertical changes in grain size. All of these suggested that the upper section is loessic material deposited by water.

研究结果表明：凤凰山剖面上部含有砾石，粗粒组分含量较高，且垂向变化均较大，分选性较差，但同时颗粒组成仍以风成沉积的两个主要粒级为主，为经流水作用改造的次生黄土。

Assumed that the coherence of the wind load in vertical is the same to the wind speed, the auto power spectrum and cross power spectrum of the wind load on the tower is formulated. Futhermore, the analysis shows that the contribution of the turbulence is about equal to the vortex shedding for the cross-wind motivation.

基于风荷载竖向相干性与风速相干性一致的假设，得到输电塔不同高度的风荷载自谱与互谱，并分析输电塔横风向激励的组成，识别出紊流激励部分与旋涡脱落激励部分约各占一半。
