two-level system meaning in English
二位准系统
Examples
- Much better to stick with a two - level system of pass and fail , or ( if you will insist on such elitism ) one extra level of “ pass with distinction ” for the top quartile
最好还是继续两级方案，即通过和不通过，或者（若坚持精英主义）再为顶尖者增加“优秀通过”这个额外的级别。 - The modeling problem of the two - level system exposed to open environment is mainly investigated based on the lindblad quantum master equation described in terms of the density matrix
