Based on the extended Huygens-Fresnel principle and the quadratic approximation of phase structure function, we have derived the analyticl expression of the spatial degree of coherence for partially coherent flattened beams propagating through the slant turbulent atmosphere with the help of tensor integral, then analyzed the effects of different zenith angle, propagation distance, coherence of source and outer scale of turbulence on the spatial degree of coherence on the receiver.

基于广义惠更斯-菲涅耳原理和相位结构函数的平方近似，运用张量积分的方法导出了部分相干平顶光束通过斜程湍流大气传输后接收面光束空间相干度的解析表达式，分析了不同天顶角、传输距离、光源相干性以及湍流外尺度对接收面光束空间相干度的影响。

The biggest advantage of this mean is that don"t need to computer the perturbation matrix element by using zero level wave function, even don"t need to give out high rank amendatory result using infinite series to sum like the ordinary perturbation theory. Thus, it not only avoids many complicated integral operation, but also obtains high rank amendatory result that it is very difficult to get or cant get.

这种方法最大的优点就是不需要用零级波函数来计算微扰矩阵元，更不需要像普通微扰论那样用无穷级数求和给出高阶修正的结果，这样一来，不仅避免了许多繁复的积分运算，而且求得了普通微扰论很难得到或不可能得到的高阶修正的结果。

The integral group rings of finite abelian groups are of great importance in algebraic k-theory.

有限交换群的整群环是一类非常重要的环，计算它的相对K_1群在代数K-理论中具有重要的意义。

Its hydrophilic groups is the inside carbonyl and amine base, and its lipophilic groups is the inside hydrocarbon chain and outer methyl. PAMAM of integral generation basically has not the surface activity. Its reason is that its outer groups is acylamino groups having very strong hydrophilicity so as not to reduce the surface tension of water. PAMAM different from traditional surfactant, have not critical micelle concentration, and exist in the form of "unimolecule micelle" in water.

结果表明：半代的PAMAM水溶液的表面活性与其分子具有两亲结构有关，亲水基团是内部的羰基和胺基，亲油基团是内部的碳氢链和外层的甲基；整代的PAMAM水溶液基本上没有表面活性，其原因是其最外层基团是酰胺基，亲水性很强，不能降低水的表面张力；树状大分子与传统的表面活性剂不同，不存在临界胶束浓度，在水中是以&单分子胶束&形式存在。

The demulsification mechanism of PAMAM belongs to displacing mechanism. Acylamino groups of PAMAM of integral having strong polarity can take place chemical adsorption with the materials of strong polarity in the exterior of oil drop and be participated in into the membrane, which will result in adsorbed crude surfactant and other active materials to be partially displaced and reduce the intensity of interfacial film between oil and water.

其机理是由于整代的PAMAM具有强极性的酰胺基团，能与油滴表面的强极性的物质发生化学吸咐作用，参与成膜，能把原来吸咐的天然活性剂分子和其它活性物质部分顶替，削弱油水界面膜强度。

After the sea trial, the control algorithm is further improved by using H〓 integral control and μ-analysis respectively to solve the problem of the adscititious integrator and the selection of weighting functions

海上试验后，为实现样机产品化，分别用H〓积分控制和μ分析对原控制算法进行了改进，以解决原控制算法外加积分器和权函数选择的问题。

EBay expresses, because spending of afore-mentioned consumer of 3 big markets will decrease, adscititious on of market of integral electron business affairs add fast will slow down, predicting company will encounter a lot of difficulty this year.

eBay表示，由于上述三大市场消费者开支将会减少，外加上整体电子商务市场的增速将会减缓，预计公司在今年将会遭遇很多的困难。
