starting length的意思|示意

For example, to describe a rectangle, you specify the starting point for the top left corner, and then the length of the two sides.

比如矩形只需要给出左上角作为起点，再加上两条边的长度就行了。

A good starting point would be 512mb, then move up or down to determine optimal value, measure throughput or response times, and analyze GC logs to understand frequency and length of scavenges.

一种不错的做法是，从512 MB开始，然后逐步向上或向下，以确定最优值、测定吞吐量或响应时间，并分析gc日志，以了解进行清除操作的频率及时间。

For a seemingly trivial example, imagine a frog making repeated jumps of the same length in the same direction, starting from the corner of a square on an infinite checkerboard.

举个看似平凡的例子，假设一只青蛙从无限大棋盘上一个方块的角落出发，以相同步长朝相同象限方向一再重复跳跃[3]。
