Wavelet multi-scale analysis is applied to the research on lunar gravity field and the explanation of lunar inner structure. In this paper, the nearside of the Moon with higher quality data is chosen as the test area, and free air gravity data from "Clementine" mission are used as original data to decompose gravity of some specific mare basins. With the results of numerical test, we also explain the hierarchical structure of the Moon, analyze the thickness of mare fillings and the Moho topography under mare basins, and verify the results by comparisons.

本文将小波多尺度分析引入月球重力场的研究，选取测量数据质量较好的月球近区作为实验区域，以"Clementine"探测器获得的自由空气重力异常作为原始数据对主要月海盆地进行了局部的重力异常分解，解释了月球内部基本分层结构，并利用主要月海盆地的实验结果分析了月海下部质量异常以及莫霍面的起伏形态，与已有研究成果进行比较证明了方法的适用性及结果的合理性。

Using the seale separation method, the meso-scale structure of Mcc occ- ured near the Delta Area of the Pearl River is studied. It is shown that there is a meso-scale cyclonic circulation at 1000 hpa level and a meso-scale anticyclon at 200 hpa level associated with the Mcc. The axis of the Meso-scale cyclone center tilts northwestward with height, stretching up to 400 hpa level.

用滤波方法分析了一例发生在珠江口附近地区的Mcc的中尺度结构，结果表明，在对流层下部有中尺度的气旋性涡旋与Mcc相应，涡旋的中心轴线随高度向西北方向倾斜，在地面涡旋的上方200hPa层上，是一中尺度的反气旋性涡旋，中尺度的辐合中心和上升运动中心偏于Mcc的西部，扰动温度场也是非对称的，在对流层上部没有中尺度的暖高压。

Shimeng realgar deposit in Hunan has the typical three floor texture modle:top is silicatite,breccia is on middle,orpiment and realgar is under,both of strata and structure control the deposit's forming.

湖南石门雄黄矿床，具有典型的三层结构模式，顶部为硅质岩，中部为角砾岩，下部为雌－雄黄矿体。

The problem this can create for you is that in a C++ compilation unit, try is a statement verb that pairs with catch to invoke a completely different exception mechanism that's part of the C++ language. C++ exceptions don't work in a driver unless you manage to duplicate some infrastructure from the run-time library.

这个可以为你创建的程序是：在一个C++编辑单元中，try是一个声明动词，它同捕获来调用一个完全不同的异常结构----C++语言的一部分。C++异常不工作在一个驱动中，除非你管理从运行时间库中复制一些下部构造。

M and RCC concrete below the elevation and with an upstream conventional concrete slab structure for impermeabilization,the authors develop an inhomogeneous multi laminate media element model for seepage analysis of RCC dams based on the research of the numerical procedure of nodal virtual flux and the technique of draining substructure for drainage holes.

基于长江三峡大坝碾压混凝土方案左厂房 12号坝段上部为常态混凝土、下部为上下游面均设有常态混凝土的防渗结构型式的碾压混凝土坝的特点，借助于渗流场求解的结点虚流量法及排水子结构技术，并提出&排水孔开关器&的概念和渗流非均质成层材料单元模型，对坝中设计时存在的主要渗流疑虑问题、大坝的防渗与排水设施渗控方案的特性进行了数值分析研究。
