各位大侠,我在看英文资料时,发现个问题,就是在有关开关管的导通和截止时,英文单词弄的我好晕
closed open这两个哪一个才是开关管的导通和截止呢?
请教:开关管导通和截止的英文?

In this case, the illumination system is designed in such a way that the current discharge interacting with the transformation ratio of the transformer T generates, after the closing of the switch T.sub.Q, a sufficiently high external voltage across the discharge lamp L in order to allow the latter to arc through.
In the case of the forward converter, a current flow through the primary winding W1 is generated initially in a conventional manner, the turns ratio of the transformer T being designed such that the current flow through the primary winding W1 induces an ignition voltage in the secondary winding W2 and thus indirectly across the discharge lamp L. If the switch T.sub.Q is opened by the control device SE, then energy at least in the form of a residual magnetization of the transformer T remains in the secondary circuit S.

就凭最后一句 - If the switch T.sub.Q is opened by the control device SE, then energy at least in the form of a residual magnetization of the transformer T remains in the secondary circuit S. 可知 open 是关断.
