VARIAN中锁场时对话框中的lock level代表什么?

虽然不知道lock level具体意思，但现在知道应该是成梯形时表示场被锁住。

应该代表的是磁场的稳定程度

因为锁场就是为了使磁场稳定不漂移

只是我个人理解

可能是扫描时场频会发生微小的变化，锁场后使信号也随之变化不致产生偏差，特别在长时间扫描后累计分辨率不会下降。

The lock level should be related to the lock power and lock gain parameters. Usually when you start to lock a signal, you can set the lock power to a relatively higher value, e.g. 35, when the lock level approaches 100 or something, you can adjust the lock power to a lower value, please keep in mind that the values of lock power and lock gain should be similar.
If the lock level is negative, you should adjust the lock phase.
