光学元件的广义光线传递矩阵可用初始型像差的矩阵形式表达。

Aberrations of the primary type, expressed in their matrix forms, are used to write the generalized ray transfer matrix of an optical component.

在常量表达式，比如枚举型常量、位域的宽度或是静态变量的初始值，是不允许使用在这种声明中的。

Embedded statements are not allowed in constant expressions, such as the value of an enumeration constant, the width of a bit-field, or the initial value of a static variable.

,目前为止我所做的,都是沿着这曲线，如果把它们都拿掉，如果这是理想型弹簧，它就会回到初始长度，它是这样表现的。

so what I've done is I effectively went along this curve, and if I take them off, if it is an ideal spring, then it goes back to its original length, which it does.

So this declares an integer, a variable of type int called I, 0 and initializes it to zero.

所以这里声明了一个整型数，一个叫做I的整型变量，把它初始化为。
