Many polarimetric target decompositions were explored, and support vector machine was applied to the classification of polarimetric SAR image. A new algorithm of target classification was presented based on polarimetric target decomposition and support vector machine. Finally, the effect of classification results was discussed by selecting different kernels and different parameters.

五系统地对各种极化目标分解方法进行了深入的探讨，并应用支持向量机对极化SAR图像进行分类研究，提出了一种基于极化目标分解和支持向量机的目标分类算法，并通过选择各种类型的核函数以及不同的参数，探讨其对地物目标分类结果的影响。

It is shown that the first hyperpolarizability β of barbituric acid deviratives strongly depends on the donor structure and the length of conjugate chain, but is not sensitive to the acceptor structure. The HOMO-LUMO calculations reveal that the first hyperpolarizabilities of barbituric acid deviratives are linear to the HOMO-LUMO energy gap △E.

It is found that the characteristic equations for right hand and left hand circularly polarized waves are identical.

在这种波导中，右旋和左旋圆极化波的特征方程是相同的，因此，它们的传播常数也是一样的；而当线极化波通过这种波导时，不出现极化面的旋转。

Of 92 acutely dissociated dorsal root ganglion cells recorded by current patch-clamp technique, 34% were discharged by FA application with the mean onset latencies of the first action potential being (367.34+/-32.96) s. All the FA-sensitive cells were identified as nociceptor cells by their distinguishable features of AP including longer duration, existence of a hump on the repolarizing phase, and longer after-hyperpolarization of APs.

运用电流钳记录的92个背根神经节细胞中，大约有34%的中、小细胞对甲醛溶液敏感，产生动作电位的发放，其产生动作电位的潜伏期是(367.34±32.96) s，并且单个动作电位复极化相具有伤害性感受器细胞的特征性，如动作电位间期较长、复极化相有&驼峰&以及较长的后超极化相。

Based on the analysis on the character of MPDI, the relationship between NDVI and MPDI is studied, and the threshold value of MPDI under densely vegetation covered, middle vegetation covered, sparse vegetation covered and nudation are built. MPDI＞0.12 means the surface is desert,sand or rocks; 0.01＜MPDI＜0.12 means the sureface is covered by middle vegetation, and MPDI＜0.01 means the earth is covered by densely vegetation. 4. Based on the expirical model relation between MPDI and vegetation optical thickness, the latter is computed by the modified algorithm.

在分析微波极化差异指数MPDI特性的基础上，分析了新疆植被指数NDVI和微波极化差异指数MPDI二者的相关关系，并建立了浓密植被覆盖、中等植被覆盖以及稀疏植被覆盖和裸露地表三种植被覆盖状况所对应的微波极化差异指数MPDI阈值。

UPS measurements show a decrease in work function with increasing thickness of NPB overlayer.

NPB在沉积过程中发生极化现象，在NPB膜约为单层时，极化达到最大。之后，随着NPB的进一步沉积，NPB分子间发生退极化。

In order to solve the problem of crevice corrosion resulted from the warping and cracking of the coatings, the feasibility of cathodic polarization with square wave pulse and the effectiveness of its control over wedgy crevice corrosion were explored.

在外加阴极极化的条件下，缝内极化电流相对较小，缝内极化电位比缝外金属略正；缝内Cl〓浓度降低，pH值显著升高；测定了这些参数在缝内的位置分布。

In the quasi-static area, the field distribution is almost the same as the static field; in the high frequency section, many high order modes occur, but the field uniformity is relatively better, and the field distribution is mainly the vertical polarization field; in the out of the vertical polarization area, the effect of high order modes is very serious so that the field distribution lost the property of vertical polarization.

在准静态区，场分布基本上与静态场相同；在高频区，出现了明显的高次模，但场均匀性较好，场分布主要是垂直极化场；在非垂直极化区，高次模影响非常严重，场分布失去了垂直极化的特性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
