doping level

These devices have optical waveguide structure, moderate doping level and active layer thickness.

该器件带有光波导结构并具有适当掺杂和有源层厚度.

More complex is the second argument: that doping perverts the noble spectacle of humans competing on a level field-that it is not fair play.

第二个理由比较复杂，用兴奋剂作弊玷污了人类公平竞赛的高尚场面；这种行为意味着不公平竞赛。

In case of no effects on the mechanical strength, the obtained composite membrane had higher conductivity than the PBI membrane with the same phosphoric acid doping level.

在不影响机械性能的前提下，与相同磷酸掺杂水平的PBI膜相比，PBI/ABPBI复合膜的电导率有一定程度的提高。

Experiments on diamond thick film and Boron-doping film were done by using of the computer control system, which showed computer control can enhance the stability of equipment, and increase the growth rate of diamond film to a high level.

在计算机控制下进行了CVD金刚石厚膜及掺杂实验，与手工控制相比，EACVD金刚石膜设备长时间工作的稳定性，金刚石膜的生长速度均有了明显提高。

Doping should be avoided at mid range level.

应避免在中音区使用搀杂剂.

When doping with the TM atom, the peaks of DOS shift to lower energy levels and there is significant spin splitting for TM 3d, B 2p, and N 2p electrons around the Fermi level.

因为杂质原子的引入，态密度向低能级移动并且TM3d，B2p和N2p电子态有强烈的自旋分裂。
