It is possible to let the " this " reference escape without the word " this " appearing in your program ; publishing a nonstatic inner class instance has the same effect , because an inner class holds a reference to its enclosing object s " this " reference 如果“ this ”这个词不会出现在程序中,就可让“ this ”引用转义;发布一个非静态内部类实例可以达到相同的效果,因为内部类持有对它包围的对象的“ this ”引用的引用。
In chapter two , using the hydrodynamical equations for electrons and maxwell equation and through complicated calculation , we finally obtain a set of equations which describe the non - steady and nonlinear interactions between plasma and field in the wake region of a moving body in space 第二章是从描述电子的磁流体方程和麦克斯韦方程出发,通过计算,最后得到了一组在考虑非静态极限下描述空间飞行器远尾区内等离子体与场之间的非稳态非线性相互作用耦合方程。
Reference in a static variable or data structure is clearly a no - no , but there are more subtle ways to allow a reference to escape construction , such as publishing a reference to a nonstatic inner class , or starting a thread from within a constructor which almost invariably entails publishing the reference to the new thread 引用保存在静态变量或数据结构中,但是有更微妙的方式允许引用逃避构造,如公布对非静态内部类的引用,或者从构造函数中启动一个线程(这几乎总是公布对新线程的引用) 。
