The property of the algorithms on linear problems is studied and the Broyden's methods have been proved that they are not descant. More precisely, the distances between the sequences obtained by solving the linear problems and the solutions of the linear problems do not decrease under any vector norm.

笔者研究了将该方法用于求解线性方程组时的内在性质，否定了一个自然的推测，指出它在解线性方程组时不是一个下降的算法，即所得到的点列与方程组的解之间的距离在任何向量范数意义下都不具有单调下降性。

Crime desistance is the rejection of temporary deviation from requirements of social norm during juvenile stage.

犯罪断念是抛却未成年阶段暂时性偏离社会规范要求的行为模式变化。

In fact, in today's society, devaluation of content is becoming the norm.

The routine design method of the dike dam is, which is borrowed the experience of deviser, followed the relative criteria and requests, and set up the engineering instance after making choices of the dam, to carry on the dam arrangement and figure designation. Then it should carry on the seepage analysis inside the dam and the stable calculation of the dam slope. It also needs to check whether to satisfy the norm request of design, then gets a feasible scheme.

常规的堤坝设计方法是在选定坝址后凭借设计人员的经验，遵循有关规范和运行要求，并参照已建工程实例，进行坝体布置和体形设计，然后进行坝内渗流分析和坝坡的稳定计算，以检查所选的方案是否满足设计规范的要求，如果满足，即得到一个可行方案。

Density Functional Theory in connection with accurate LCAO basis sets and norm-conserving pseudopotentials were used to study two issues which are (1) The Selective Functionalization of Single-Walled Carbon Nanotubes with Diazonium Radical and (2) The Molecular Dynamic Simulated IR Spectrum of Adsorbed C3H3 and I on the Ag(111) Surface.For the first, we investigated (1) NO2C6H4 direct addition (2) NO2C6H4N2 dissociative addition reaction on semiconductor (8,0), metallic (9,0)and(5,5) carbon nanotubes.

第一部分模拟的结果显示，在半导体性质(8，0)和金属性质(9，0)、(5，5)奈米碳管上，硝基苯自由基(NO2C6H4)的直接加成反应於不同导电性质的奈米碳管间不具有选择性，而硝基苯重氮化合物自由基(NO2C6H4N2)的解离吸附反应会选择性的与金属性质奈米碳管发生反应，因为在金属性质的系统中，奈米碳管於过渡态时会藉由电荷的转移来稳定过渡态的结构，进而帮助反应更快的进行。
