以“半导体激光器 ”、“受激辐射”、“光学谐振腔”或在本小节内自选其他知识点为中心进行发散训练,制作思维导图。要求至少发散3层。要求每个节点均加入英文标注,并尝试开展演绎训练。尝试使用超星发现系统的发现球开展数据挖掘,把发现的新知识加到你的思维导图中来。 Divergence training centered on "Semiconductor laser", "stimulated radiation", "optical resonator"or other knowledge points selected in this section can be used to make mind maps. Require at least three layers of divergence. Each node is required to join the English annotation and try to carry out deductive training. Try to use the discovery ball of the superstar discovery system to carry out data mining and add new knowledge to your mind map.
