量子观念：在量子观念中，电磁波与介质产生(微观)吸收(absorption)、自发射 (spontaneous emission)、受激发射(stimulated emission)，而产生能量等的交换，并造 成续发光子。 2.

自发射以来，工程师对飞行器各部件一直进行跟踪测试和验证。
Since the launch, engineers have been continually been conducting testing and verification of the spacecraft's components.
而且因为来自发射装置的发射框架两侧上振动更超过那二枚在中间的，路径交叉更明显。
And because vibration from the launch frame on both sides of the launcher was greater than those two in the middle, path crossing was more apparent.
比较了较高激发密度下的受激发射、自发发射和激光脉冲的时间特性，这些都证实了该发射是受激发射。
Time behaviors of the stimulated emission under relatively high pumping intensity, spontaneous emission, and laser pulses were compared, and hence the stimulated emission of ZnO thin films was proved.
