If the boy love some gril ,he would be root ,match,spacy and orniea put on the leaves present to her,the leaves syptom he have some words want speak to her,the root sypetom he is very miss her,the match means he's attitude very sure ,the spacy represention he love is ture ,and the ornia means he expect her's agreement.

小伙子爱上了某个姑娘，就用树叶包上树根、火柴、辣椒、大蒜送给她。树叶表示有很多心里话要说，树根表示思念不已，火柴喻态度坚决，辣椒喻爱得炽热，大蒜则希望同意。

Fourthly, it discusses the spectral image loss-less compression by applying thecorrelation and the entropy of the spectral image sequence. It gives and analyses three expressions of imaging spectrometer images, and tells the change in correlation coefficient and entropy for different expressions. At last, it puts forward D2PCM de-correlation method to reduce the spatial and spectral redundancy. This method improves the compression ratio and the compression efficiency, being easy and fast in operation.

Firstly, we use the mixed coordinates. More precisely, we use the spherical coordinates for independent variables in space, and so avoid the approximation of boundary conditions on the surface, which is required, if we use the Descartes coordinates.

我们所设计的求解Navier-Stokes方程的混合谱格式具有如下的一些特点：首先，我们采用混合坐标方法，即用球面坐标表示空间自变量，而用Descartes坐标表示速度分量。

In spherical polar coordinates, DRSC potential have supersymmetry and shape invariance for θ and r coordinates. By using the method of supersymmetry and shape invariance, exact bound state solutions of Schrodinger equation with double ring-shaped Coulomb potential are presented. The normalized angular wave function expressed in terms of Jacobi polynomials and the normalized radial wave function expressed in terms of the Laguerre polynomials are presented. Energy spectrum equations are obtained.
