另外，每天或每周要处理系统利用率的快照和LTP测试输出文件并得到数据分数，以确定系统在长时间运转中性能是否下降。

In addition, snapshots of system utilization and LTP test output files were taken daily or weekly to have data points to determine whether systems were degrading during long-period runs.

KH2PO4处理明显降低了甘蔗叶片水溶性蛋白质含量，而提高了中性转化酶活性。

The KH2PO4 treatment obviously decreased the water soluble protein content, but remarkably increased the neutral invertase activity in leaves.

So, actually we don't have to worry about this fact any time we're dealing with neutrals.

所以事实上当我们在处理,中性原子的时候我们不必担心。
