Results: There was high detectable rate of Salmonella serotype Derby. Salmonella serotype Agona, and Salmonella serotype Anatum, in both kinds of specimens except high detectable rate of Salmonella serotype Typhi in clinical specimens.

Based on the theoretical analysis, theimitating experiments of the first-order and second-order autofrettage process proved the validity of the theory, the feasibility of the second-order autofrettage technique itself. This kind of technique can meet the autofrettage requirements of tubes with different bore and material.

在理论分析的基础上研究了一次、二次机械自紧模拟实验，证明了理论分析预示规律的正确性、二次机械自紧技术本身是可行的，可满足不同口径和材料性能身管的自紧要求。

We extend the second order elastic tensor of Husdon's and turn it to a matrix which makes the calculation of second order perturbation much more concise. Then the azimuthally phase and group velocity formulas of plane wave propagation in horizontal plane are deduced according to Christoffel equation, and the azimuthally dependent velocities in dry and water saturated cracked medium are calculated.

而后，根据Christoffel方程推导了由各向同性背景介质中含两组非正交的垂直裂隙而形成的等效单斜各向异性介质中，在水平面内随方位变化的相速度和群速度的计算公式，并对干裂隙和饱和流体填充裂隙介质两种具体情况进行了计算。

But perhaps the confidential bachel or clerks in Tel lson' s Bank were principally occupied with the cares of other people, and perhaps second-hand cares, like second-hand clothes, come easily off and on.

C.Dickens，A Tale of Two Cities 这或者许是由于他们该署台尔森银号信得过的独身职员，次要料理的是外人的事；而外人的事，或者许和买来的旧上装一样，穿脱都很随意，用没有着多动心理。

Kinds of Schiff base derivatives of 2-N-benzylidene Furanmethanamine have been designed. The Net Charges of main atoms, bond lengths, bond angles, dihedral angles, IR have been calculated by means of HyperChem6. 0 program. 36 kinds of Schiff base derivatives of benzylidene adenine have been designed. Also the net charges of main atoms, bond lengths, bond angles, dihedral angles, IR, the energy gap △E between HOMO and LUMO and the nonlinear second-order polarizability β have been calculated by means of HyperChem6. 0 program. The calculated results indicated that the nonlinear second-order polarizability β were up in accordance with the △E down.

设计了腺嘌呤缩苯甲醛36种衍生物，计算了这些分子的气相几何，腺嘌呤缩苯甲醛中各原子的电荷分布，最高占有轨道HOMO和最低未占有轨道LUMO的能量以及它们之间的能量差△E，同时还计算了这些分子的二阶非线性极化率β，我们发现腺嘌呤缩苯甲醛的二阶非线性光学系数与△E有近似一致的变化关系，随着△E的减小，二阶非线性光学系数有增大的趋势。

Students have grasped this kind of model in the primary stage, while apply it in practice they still repeat the theme of the former sentence, which means that Vietnamese students are not skillful at the discourse cohesion; in the middle stage, there are passive sentences and "catenulate"sentences, but some of the students bring on grammatical errors while assuring the cohesiveness of discourse; in the advanced stage, the second cohesive model disappears while amount of third cohesive way appears which even more than the second one, which shows that students no longer stand on the cohesiveness formally but to make the "zero"cohesive of discourse.

另外我们还在语料中发现了被动句的语体风格出现偏差的情况。在运用被动句的语篇衔接功能时，留学生普遍运用第一种主位推进模式。在初级阶段学生就已经基本掌握了这种模式，但有时会不必要地重复前句的主位，这说明留学生对汉语的语篇衔接还不够娴熟；有的学生不能够使用被动句完成语篇衔接，可能是受词汇量的影响。
