Several technical problems in arc source design, including arc mode, arc polarity, ignition mechanism and arc confinement and macroparticle reduction were discussed.
讨论了真空电弧沉积中弧源设计的有关问题，如电弧运行模式、电弧极性、点火方式、电弧的约束方式以及宏观粒子抑制方式等。
Although small QW has smaller optical confinement factor and smaller ratio of carriers injected into QW, it can provide higher mode gain because of its smaller mixing between valence bands.
小阱宽的量子阱虽然光学限制因子和载流子注入比例都较小，但由于其价带耦合小于宽量子阱，从而具有高的模式增益，说明量子阱的能带结构对其光学特性有决定性的作用。
