In this paper, we study nonlinear perturbation analysis of mesoscale verticalcirculation and evolution equation by means of f plane, non-hydrostatic balance andfilter model. Outstanding nonlinear characteristic of mesoscale disturbance invertical direction, we obtain nonlinear symmetric disturbance equation anddisturbance amplitude s evolution equation by use of multi-scale and singularperturbation technique.

中文摘要：本文采用f平面、非静力平衡、滤声波模式，讨论了大气中尺度非线性动力学方程，通过尺度分析重点突出了扰动在垂直方向上的非线性特征，从而得到了对称扰动非线性方程，运用多重尺度方法和摄动分析讨论了对称扰动非线性重力惯性波的演化过程，得到非线性重力惯性波振幅演化服从广义的非线性Schrdinger方程。

The dish washer includes one washer body with inside washing tank, rotary door in the front of the washer body, and one sealing latch set between the washer body and the door to raise the sealing property of the door. The sealing latch includes one hook unit set inside the hole on the washer body side, one sealing unit exposed outside the washer body and contacting closely to one side of the door in close state, one central slot for telescoping the hook unit, and one expansion joint in the joint part to avoid concentration of stress.

本发明包括洗碗机内部具备了洗涤槽的本体，设置在本体的前面转动的门，设置在本体前面和门之间，当关闭门时提高门和本体前面的封闭性的碰销；其中碰销包括：在本体前面一侧形成的插入孔中设置的挂钩部，露出于本体外部，在门关闭时，紧贴门一侧面的密封部，为了使挂钩在插入孔内直径方向伸缩，而在其中央部位形成的切缝，其特征在于密封部上形成了与切缝相通，防止挂钩伸缩时应力集中到挂钩部和密封部之间结合部位上的伸缩槽。

The characteristics of Gujiao clean coal are introduced,its caking index is analyzed,coal blending is suggested for power coal.

The expedition had taken with them an elderly Arab whose main qualifications as a guide were that he had crossed the sand sea twice before in his lifetime, once as a young lad. To the expedition's amazement , he had kept the vehicles at an exact compass bearing right across the sand sea, apparently based solely on his recollection of minor features in the landscape (a hump on the horizon or a patch of unusual red sand) that he had seen only twice many years before.

该远征队随行带上了一位年长阿拉伯人，他作为向导的主要资格就是他平生曾两次穿过这个大沙海，其中一次他还是个年青小伙子，令远征队叹服的是，他带领车队迳直横穿沙海时与罗盘方向完全吻合，显然他全靠回忆那些只在多年前见识过两次的细小的地貌特征(如地平线上的一个土丘或者一片非同一般的红色沙漠)。

Under the guide of the theory of dynamic system of entrapment, the main methods applied here are multidisciplinary analysis and comprehensive study. The characteristics of compaction curves, the evolution of organic matter, the direction of migration and assignment, conduit system, fluid potential are studied It is concluded that the low maturity of the source of the Eogene age is the main factor to control the entrapment.

Hence guiding residents consumption is meaningful to upgrade of consumption and industry structure. The article first give out a conclusion that consumption structure of Chinese urban residents is on the stage of comparatively well-off ; Making use of Extended Linear Expenditure Systemand utilizing time series analysis、cross data analysis、angle index analysis and elasticity analysis,we find the following characters in consumption structure of Chinese urban residents in transition age: the generally comparatively low consumption level,evolving to optimization in general consumption structure,paying more attention to material consumption but less attention to culture consumption and service consumption,crosswise duality,consumption identically.

文章对目前我国城镇居民消费结构所处阶段作出了判断，认为已经处于总体小康型消费阶段；借助扩展线性支出系统模型，运用时间序列分析、横截面数据分析、恩格尔系数分析和弹性分析等手段，我们发现转型时期我国城镇居民消费结构具有总体消费水平偏低、运动方向逐步趋于优化、重物质消费、轻文化和劳务消费、横向二元化、雷同化等特征。

This research beginning with industry link does systematic research to the development of the dairy industry of our country and strives to accurately summarize the characteristics of each link during the course of development.

在课题研究的过程中，按照不同的环节对我国奶业的发展历程展开全过程的分析和纵向透视，并将各环节划分为不同的发展阶段，对各个阶段的特征进行总结、归纳和概括，在此基础上，提出了我国奶业的发展方向。

The features of authority orientation in customers are varied with the times, and with the state laws getting increasingly perfect, the development direction of advertisement will certainly be adjusted, only in this case can the advertisement industry stand up in the ever-varying environment.

Numerical simulation shows that the location and intensity of the modeled high and low pressure centers is consistent with the observation. The pressure gradient intensity of cyclone closes to observation. The regional distribution, transportation direction, centers of the cold, worm advections have similar characters with fact. On the other hand, the temperature stratosphere simulation result is slightly bigger than the fact.

数值模拟结果表明，模拟高压、低压中心位置和强度与实况较为吻合，气旋的气压梯度强度与实况较为接近；冷暖平流在分布区域、输送方向、强中心位置上也与实况具有较相似的特征，但是温度平流模拟的结果在量值上略大于实况。
