The space efficiency afforded by efficient check-in is greatly increased in cases where the amount of change between versions is relatively low (as was the case in the development system under test).

如果各个版本之间的差异较小(例如所测试的开发系统)，则高效签入的空间效率则会大大增加。

The major reason for such low values is the fact that most crop plants display their maximal photosynthetic efficiency for relatively brief periods of time during the life cycle of the plant.

这样低值的主要原因是，大多数作物只能在整个生命周期中相对短的时期内表现出最大的光合效率。

It involves relatively low overhead on the server, so you might query it periodically on a production server to check the overall efficiency of the compression feature.

它在服务器上涉及的损坏是比较低的，因此可以定期查询来检查压缩特性的整体效果。

And, although the authors report relatively low efficiency so far, in the context of someone who does not have any banked sperm to fall back on, these odds are probably very encouraging to make this kind of approach worthwhile.
