And by applying the linear dispersion relation of wave, all the properties of wave refraction including wave rays, constant phase lines, phase function and crest lines etc., can be expressed in explicit functions. By introducing an orthogonal curvilinear coordinate along the wave ray and the constant phase line, and with an estimated scale factor, the refraction coefficients along any wave ray can then be determined. The present results are verified by ordinary wave ray theory and some previous numerical results.

就此特例情况在波浪的线性分散关係的应用下，前进波浪折射现象的整体特性，包括波向线、等位相线、位相函数与波峰线皆被导述出明確显然的函数表示；同时引入由沿著波向线与等位相线所构成的完全符合波浪折射几何通性的正交曲线座標，求出其尺度因子后，由能通量守衡原则定出沿著任一条波向线上的折射係数；並由之对往昔纯依两相邻的波向线间的几何类比所给定的折射係数给予导証之。

November 11,"Singles Day" in this special day, a few number of entertainment of the "bachelor" or JobHunting, or Nagusa ownerless, hey, really is a lot.

Based on a general parametric eigenstructure assignment result proposed for descriptor linear systems via proportional plus partial derivative state feedback and a result for generalized eigenvalue sensitivity problem of matrix pairs, parametric representation of the closed-loop eigenvalue sensitivities to the perturbed elements in the open-loop system matrices is obtained. An effective algorithm for eigenvalue assignment with minimum sensitivity in descriptor linear systems via proportional plus partial derivative state feedback is then proposed.

The statistical difference of proinsulin rather than HOMA index was found among the patients of various Gensini's score group (Gensini's score was examined as a categorical variable classified by tertile values) and significantly stenosed vessels group by means of the results of analysis of covariate variance after adjusting for age, sex and body mass index (p＜0.05), and the partial correlation coefficient between proinsulin level and Gensini's score, the number of significantly stenosed vessels after adjusting for age, sex and body mass index was 0.3156 (P＜0.01) and 0.2752 (P＜0.05) respectively. Multivariate linear regression analysis indicated that the level of proinsulin was positively correlated with the Gensini's score (P＜0.01). The results of multivariate stepwise Logistic indicated that the proinsulin was the independent risk factor for the coronary heart disease, and the odds ratio (95％ confidence interval) was 2.268 (1.253～4.105)(P=0.007), however, the HOMA was refused by the final model.

年龄、性别与体重指数为控制变量的协方差分析结果显示，胰岛素原的水平在不同的Gensini评分组、冠状动脉病变血管数分组中分布有统计学差异(P＜0.05)，偏相关分析示胰岛素原的含量与Gensini评分与病变血管数显著正相关，其偏相关系数分别为0.3156(P＜0.01)与0.2752(P＜0.05)，而HOMA指数与两种评分的相关未有统计学意义；多因素线性逐步回归分析结果示胰岛素原水平与Gensini评分独立正相关(P＜0.01)；多因素Logistic回归分析显示，胰岛素原的水平为冠心病的独立的危险因素，其OR值及其95％可信区间为2.268(1.253～4.105)(P＜0.01)，HOMA指数未进入模型。

And in the process of producing the concepts of the total derivative and the partial derivative are confused.

而且在整个推导过程中，对于全导数和偏导数的概念没有分清楚。

When we use boundary element method to solve problems of fluid structure interaction, large amount of calculation of Green's function and its partial derivative is required.

The later questionnaire mainly includes information of paterfamilias, like gender, age, education background, family members, family income and expenses, the number of working labors and schooling kids/drop-outs, attitudes to gender difference in education, women's status at home and in society, comments and suggestions to the compulsory education.

农民/家长问卷，调查内容主要涉及：性别年龄职业文化程度、家中人口和子女个数、家中打工人数、家中上年经济收支情况、读书子女数、失学子女数及原因、对男孩女孩受教育的态度、当地妇女在家庭社会中的地位与以前的比较、对农村义务教育和女童受教育的建议和看法等方面的内容。

Along with increment of mean photon number, there is no change in the oscillation period of the squeezing curve, but its scope increases obviously and its stability begins to reduce; when the mean photon number and the field mold structure fixed, the speed of moving atom has a great infection on the extent and period of the radiation squeeze. With the speed of moving atom increasing, not only the complete squeezing effect would be archived, the stability would also enhance.

随着平均光子数的增加，压缩曲线的振荡周期没有明显的变化，压缩曲线的振荡幅度明显增大，压缩的稳定性变小；在平均光子数和场模结构参数一定时，原子运动速度对光场压缩的深度以及压缩周期影响程度较大，增大原子运动速度，不但可以实现完全压缩光场，而且压缩的稳定性得到提高。

Benched on Saturday after enduring a lengthy skid, Robinson Cano stepped in and blooped a two-run double down the left-field line, part of what would end up as a three-RBI day. Cano also had a pinch-hit RBI single in the eighth inning on Saturday and suddenly has three hits in his last five at-bats after enduring an 0-for-17 skid.
