英汉例句
- V and N. And I'll just write the result.
N不变，我只是写出结果。 - If I take dQ / d beta, keeping V and N constant, then I get derivative with respect to beta.
求导数dQ/dβ,同时保持V和N不变，就得到了对β的导数。 - Accordingly, the I-V characteristics of N and P type DBRs due to three kinds of current mechanisms:the drift-diffusion, pure drift and thermionic emission currents, have been analyzed theoretically.
并以此为依据，从理论上分别分析和比较了多子漂移扩散、纯漂移和热电子发射电流机制所起的作用。
