That vector is called a "null vector".
那种矢量就叫做”零矢量“。
Lastly, the memory allocated to the vector is also freed and NULL vector is returned to the caller.
最后，还要释放分配给向量的内存并把NULL向量返回给调用者。
This routine initially checks to see if NULL manager entry point vector, mgr_epv, was passed.
这个例程首先检查传递的管理器入口点向量mgr_epv是否是NULL。
Else, it goes through the binding vector array looking for a non-NULL pointer to binding handle.
否则，它循环遍历绑定向量数组，寻找非null的绑定句柄指针。
In this paper the focal mechanism of the major shock and several aftershocks has been studied and the strike of seismic fracture has been also determined by means of null vector data.
本文研究了主震与若干余震的震源机制解，并应用零矢量方法确定了地震破裂面的走向。
