COV gathers can also be constructed through selecting traces from different cross spreads of a 3D survey. A simple and practical way of constructing COV gathers can he described as that 1 when a dominant receiver line direction is determined, the inline offset and crossline offset of every trace can be calculated; 2 the inline offset and crossline offset ranges fruit; negative to positive for the whole dataset can be well represented by the range of the receiver spread of a typical source; 3 the full range of inline offsets can be divided into several sob ranges using twice the source line spacing and the full range of crossline offsets can be divided using twice the receiver line spacing; and 4 one sod; sob-range inline offset and one such sob-range crossline offsets form a COV gather.

一个简便实用的构造COV道集的方法是：在给定检波线的走向后，计算出每一地震道的inline炮检距和crossline炮检距；用观测系统中一个具有代表性的炮点的检波器排列范围来确定整个数据的inline炮检距范围和crossline炮检距范围，用两倍的炮线间距把inline炮检距的范围分成若干份，用两倍的检波线间距将crossline炮检距的范围也分成若干份，一份inline炮检距和一份crossline炮检距就构成一个炮检距向量道集。

In his article entitled "On the manufacture of diffraction gratings and theoretical," the paper wrote,"If every inch with the same number of two engraved lines in contact with photographic copies of the state, the two grating The engraved lines are almost parallel will result in a set of parallel stripes, the direction of the two grating carved exterior angle between the line bisection, and their distance decreases with increasing inclination."

他在一篇题为"关于衍射光栅的制造和理论"的论文中写到"如果把每英寸具有同样数目的刻线的两个照相复制品处于接触状态，使两个光栅中的刻线几乎平行则就会产生一组平行的条纹，其方向将两个光栅刻线之间的外角二等分，而其距离随着倾角的减小而增大"。

According to theory analysis and example computation, the following conclusions are obtained.1. During the analysis on the cable shape in the suspension bridge"s completion state, the pre-displacement of saddle and the case that the cable and stiff girder commonly bear the second-stage dead load should be considered.2. When supposing the construction ideal initial state in the first time, if the initial state model is established according the cable"s span central sag in the bridge"s completion state, and the reasonable correction formulation is created in the iteration process, the result can converges fast.3. The cable shape in the bridge"s completion state is not parabolic, nor catenary. It is between parabola and catenary. Actually it is funicular polygon closer to the catenary.

通过理论分析和实例的计算表明：1在悬索桥主缆成桥线形分析过程中，须考虑主塔鞍座的偏位以及二期恒载由主缆和加劲梁共同承担的实际情况；2在第一次假设施工理想初态时，以成桥状态已知的主缆跨中垂度建立施工理想初态模型，同时在迭代计算的过程中，建立合理的修正公式，才能使收敛的速度快：3在成桥状态时主缆的线形既不是抛物线，也不是悬链线，而是介于抛物线与悬链线之间，更接近于悬链线的索多边形。

We also used the latent heat daily data、sensible heat daily data、relative humidity data and OLR daily data from NCEP-DOE Reanalysis2 which formed as 2.5-degree latitude x 2.5-degree longitude global grid with 144x73 points(1982～2005). The data of subtropic high ridge offered by Bational Climate Center . With singular value decomposition analysis, we studied key region of ocean-atmosphere interaction in the mid-latitudes in the Pacific. Second, by using wavelet analysis to study the character of the key regions of SST.Moreover the correlation analysis can help us to understand the reason of the cold water formed and the physical process of ocean-atmosphere interaction in the mid-latitudes in the Pacific. There are three mostly SVD modes which contribution reach to 70%,So the three mostly modes can reflect the mostly structure in the key region.
