real gradient的意思|示意

The practical examples indicate that real earthquake occurrences better correspond to the trends of high gradient zone of gravity variation.

实例表明，实际发生地震的情况和重力变化高梯度带的走向对应较好。

In the gradient image, only the summits of main peaks corresponding to real edges are extracted, where as the little sharp maxima in edges' vicinity caused by noises would not be chosen.

并且它仅选取出梯度图中相应于边缘的极大值点，在其附近由噪声引起的小的极大值点不会被选取出。

The gradient projection algorithms are constructed for the real-time computation of trajectory optimization, and the concrete steps of the algorithms are also given.

为了轨道优化的实时计算，构造了一类梯度投影下降算法，并且给出实际应用的具体步骤。
