two-state

双态,双稳

Thus, the only two magnetic fields for which we have any significant historical record are bitable. 这样，我们己有重要历史纪录的惟一的两个磁场是双稳态的。

The crystals are bistable, which means that they can remain in either a reflective or non-reflective state without any power. 这种液晶是双稳态的，意即没电时能保持反射状态或非反射状态。
