1·If we wait until the end of the sprint to do this, any diverging code will be discovered at precisely the wrong moment - when we have the least time to fix it.
如果我们等到sprint结束再做，任何分叉的代码就会在错误的时刻发现——此时我们能够用来修复问题的时间最少。
2·Diverging code (merging conflicts).
分叉代码(合并冲突)。
3·Radii stop converging as they approach the event horizon, are parallel at the horizon, and begin diverging in the interior.
当它们接近活动视界时候半径阻止了收缩，是与视界平行，而开始在内部分叉。
