静态内存

数据区域同时包括静态分配的内存（比如全局和静态数据）和动态分配的内存（通常称为堆）。

The data region includes both statically allocated memory ( such as global and static data ) and dynamically allocated memory ( often called the heap ) .

用十字链表存储导纳矩阵元素，可有效地克服以往静态数组浪费内存的缺点.当网络结构改变时，导纳矩阵的动态存储结构能够快速地实现导纳矩阵的修改，从而减少整个潮流计算的时间。

At the same time , when the power system structure is changed , the new dynamic method can rapidly modify the element of conduction matrix , and reduce the time of load flow .

新方法中，先建立程序的函数动态调用树，其中包含程序分配释放内存的信息，再在调用树中总结程序的静态性质，为内存泄漏定位提供有价值的信息。

In the new approach , dynamic function calling tree with data about memory allocation and release of the running program is constructed first , then the static property of the program is extracted from the dynamic tree which provides some valuable information for memory leak detection and location .
