根据定容燃烧气体状态方程和火药几何燃烧定律，推导出一种确定钝感发射药特征量的计算方法，并对某种火药进行钝感处理和计算，结果与火药切片的电扫描结果相符。

We did not define a const version of the increment and decrement operators. Why?

没有定义自增和自减操作符的 const 版本，为什么？

If the keyword volatile is placed after const , then this allows external routines to modify the variable.

如果关键字 volatile 放在 const 之后，这使得外部命令可以修改变量。

We can define a non const variable in one file andassuming an appropriate declaration has been madecan use that variable in another file

我们可以把一个非 const 变更定义在一个文件中，假设已经做了合适的声明，就可在另外的文件中使用这个变量

When Const is used in got-up member function, we should make sure he is Logical Constness as far as possible.

const用在修饰成员函数时，我们要尽可能保证他是logical constness。

And, as the Vatican Council has said,"the Church herself, is, by her marvellous propagation, her wondrous sanctity, her inexhaustible fruitfulness in good works, her Catholic unity, and her enduring stability, a great and perpetual motive of credibility and an irrefragable witness to her Divine commission" Const.

此外，由於梵蒂冈会议已表示，教会自己，是中，她的绝妙的繁殖，她惊异的神圣性，她取之不尽，用之不竭的成果，在好的作品，她的天主教团结，和她的长期稳定，一个伟大而永恒的动机，信誉和一个不可争辩的见证，她的神委员会

Although staff_size is initialized with a literal constant, staff_size itself is a non const object. Its value can be known only at run time, so it is illegal as an array dimension.

虽然 staff_size 是用字面值常量进行初始化，但 staff_size 本身是一个非 const 对象，只有在运行时才能获得它的值，因此，使用该变量来定义数组维数是非法的。

In Section 2.2 (p. 40) we first used string literals and learned that the type of a string literal is array of constant characters. We can now be more explicit and note that the type of a string literal is an array of const char. A string literal is an instance of a more general construct that C++ inherits from C: C-style character strings .

在 第 2.2 节中我们第一次使用了字符串字面值，并了解字符串字面值的类型是字符常量的数组，现在可以更明确地认识到：字符串字面值的类型就是 const char 类型的数组。C++从 C 语言继承下来的一种通用结构是 C 风格字符串，而字符串字面值就是该类型的实例。

A reference that may be bound only to a non const lvalue of the same type as the reference.

只能绑定到与该引用同类型的非 const 左值的引用。

A non const lvalue may be read and written.

非 const 左值可以读也可以写。

The work of this paper is as follows: 1. Looking back the progressing history of the linear motor, introducing the features of the elevator driven by linear induction motor, radicating the topic of this paper "the digital frequency variable control of the elevator bi-side direct driven by linear induction motor". The research of this paper covers the conventional VVVF control, space vector based VVVF control, vector control and DTC.

本文主要开展了以下几个方面的工作： 1 回顾了直线电机发展历史，电机的驱动技术演变，特别是针对直线电机的驱动，简要介绍了直线感应电机驱动电梯的优点和不同结构类型，对传统的v／f控制，基于空间矢量法的v／f控制，矢量控制，和基于电压空间矢量的直接转矩控制进行了比较，确立了本课题的研究主题：直线感应电机双边直推式驱动电梯的全数字变频控制。
