Concurrency in the java.util.concurrent collection is enabled via re-entrant read-write locks and is now supported natively inside Terracotta 2.4.
concurrent中的集合的并发性是通过再入读写锁实现的，现在已经得到Terracotta 2.4的原生支持。
This can happen if XML documents are parsed infrequently, or if the number of threads within your application varies widely (Xerces-C++ parsers are not re-entrant).
如果不经常解析XML文档，或者应用程序中的线程数量变化很大（Xerces-C++解析器不支持再次进入），就会出现这种情况。
Thus re-entrant section of code usually must use local variables only in such a way that each and every call to the code gets its own unique copy of data .
因此，代码的可重入区域通常必须使用局部变量，也仅以此方式，每个对这些代码的调用才会有独属于自己的一份数据副本。
In view of the multiple re-entrant characteristics of wafer manufacturing systems, this paper presents some concepts such as cycle time per layer and logical layer number.
针对晶圆制造系统的多重入特性，提出了层周期、逻辑层数等概念。
A mechanical model of two-dimensional cellular materials with negative Poisson's ratio, composed of partly re-entrant and partly regular hexagons, was proposed based on rotation mechanism.
基于旋转机制，提出了一种具有负泊松比效应的、由部分内凹以及部分规则六边形组成的二维多胞材料力学模型；
