It can't be avoided for the proofreader s to be faced the difficulties in telling true or false.

做不到这一点，校是非就无从谈起，读校活动也就失去了意义。

For a broader usage of theorem 2, a further research is conducted to any infinite group as long as its proper subgroup is p -.

将上面定理2进行推广，即对任一真子群为p -群的有限群进行了研究，当IP -群是非p -群时，既是通常讲的内p -群。

Whether an NTB is protectionist is sometimes difficult to identify in the presence of market failure.

是不是是非关税壁垒的保护主义是一种有时难以确定，在存在市场失灵。

The non linear regression applied to relation of the proton change number of acid with the proton concentration may improve the precision of pKa determination.

它首先牵涉到有机酸在溶剂中的电离形式[1]，然后是电离平衡常数中活度系数的测定[2]，再者是非水质子溶剂或有机-水溶液中质子浓度的精确测定。

This version is of great worth in the study of the Psalter.

An analytical model of non-linear shock response of the equipment using shock isolator with displacement restrictor is established and the pseudo-force approach is used for the first time to solve the response.

带有限位器的浮筏隔振系统是非线性系统，该文建立了这一非线性系统的模型，利用伪力(pseudo-forces)法计算了带有限位器的浮筏隔振系统模型的冲击响应，分析了限位器参数对冲击响应的影响。

An analytical model of non-linear shock response of the equipment using shock isolator with displacement restrictor is established and the pseudo-force approach is used for the first time to solve the response.An experimental model of the equipment using shock isolator with displacement restrictor is made.
