The right is the top bid, which is adwords sponsored links, to run this ad only can be put into the background, he was point per Hit a number of accounting for the cost of money. google ranking is on the left refers to the left side of the designated sites in the google page rank search results, which is quite different from the right side. google rank him on the left is a natural ranking, google to improve the user experience is set up, he was among the network all of the pages google user input keywords with relevance, importance, timeliness for scoring derived row order of the results. This order is not the same as the right can get paid ranks.

右边是竞价排名，也就是adwords赞助商链接，要投放这个广告只需要进后台进行投放就可以，他是按每被点击一次多少钱来核算费用的。google左侧排名是指将指定网站出现在google左侧排名搜索结果中的首页，这与右侧有有很大的差别。google左侧排名他是一种自然排名，是google为提高用户感受而设立的，他是google根据网络当中所有网页与用户输入的关键词的相关性、重要性、及时性进行打分得出的排顺序结果。

The results showed that:(1)IRBB21 was resistant to all the strains except T7147,astrain from Japan belonging to the Japanese racial group 2,whereas Minghui 63 and 6078 weremoderately susceptible to most of the strains tested;(2) The resistance reactions of the hybrids derivedfrom IRBB21 appeared to be the same as that of IRBB21,whereas that of the hybrids derived fromMinghui 63 and 6078 were more susceptible to BB than the two restorers.

结果表明，IRBB21除不抗日本的T2菌系群外，对所有其它供试菌株均表现高抗，恢复系明恢63和6078对供试菌株多为中感，以明恢63或6078配组的杂交稻的抗性极差，而源于IRBB21的杂交稻的抗性与IRBB21基本相同，因而证实Xa21基因确为在我国极具应用价值的抗性基因，完全可以用于杂交水稻的白叶枯病抗性改良。

From Maxwell's equations, with material constitutive relation of optically active crystal and boundary conditions of electric field on the boundary between isotropic media and crystal, through coordinate transformation, the formula of the direction of refracted wave for arbitrary direction incident monochromic plane wave was derived. Furthermore, based on the unit vector of direction of refracted wave, eigen waves of electric field, electric displacement vectors and direction of energy flow can be easily obtained.

从麦克斯韦方程组出发，结合旋光晶体的物质方程以及单色平面波从各向同性介质入射到晶体界面时电场的连续性边界条件，通过晶体主轴坐标系和界面坐标系的坐标变换，推导了任意入射方向的单色平面波在晶体界面上的折射方向的求解公式，进而利用所得的折射方向求解晶体中折射波的电场本征模、电位移矢量本征模和光线方向。

First, total resistance is derived by summing different resistance components. The relationship between resistance of still plane bed and energy slope has been proposed from the similarity between sediment incipient motion and still bed resistance. And this relationship can be used in computing grain resistance.

一是从不同的床面阻力单元出发，利用泥沙起动与定床阻力之间的相似性研究了静平整床面的阻力，建立了静平整床面阻力与能坡之间的关系式，并将此式用于沙粒阻力的计算。

Second, based on the spherical vector wave function in uniaxial anisotropic medium, and the first, second, third and fourth spherical Bessel functions satisfy the same differential equation and recursive formula. The scattering fields in terms of spherical vector wave function from a uniaxial anisotropic spherical shell and an anisotropic uniaxial-coated conducting sphere by a plane wave are derived. The electromagnetic fields in uniaxial anisotropic medium and free space can be expressed in terms of spherical vector wave functions in uniaxial anisotropic media and isotropic medium.

二、在建立均匀各向异性单轴介质球矢量波函数理论的基础上，利用二阶线性偏微分方程的性质和第一、第二、第三和第四类球Bessel函数满足相同的微分方程和递推关系，我们分别研究了单轴介质球壳和单轴介质涂覆导体球对平面波的电磁散射特性，首先给出了各个区域的电磁场用球矢量波函数来表示的解析表达式，进而利用电磁场在边界上满足电磁场切向连续的边界条件和球谐函数的正交性，得出了各向异性单轴介质球结构中电磁场用球矢量波函数表示的系数所满足的矩阵方程。
