In this thesis, the study results of the basic characteristics of laser-ablation Cu plasma are given, Following are the details, The research of laser induced Cu plasma emission spectra in airUsing Nd:YAG laser (with a wavelength of 1064nm and a pulse width of 10ns) ablate copper target in air to observe the emission spectra of plasma.

本论文采用光谱方法对激光烧蚀产生的Cu等离子体的基本特征进行了实验研究，主要内容有：空气中激光烧蚀Cu产生等离子体发射光谱的研究利用Q-开关Nd∶YAG激光器产生的1.06μm、10ns的脉冲激光聚焦在空气中的Cu靶上，观测了激光诱导的Cu等离子体发射光谱。

Because the disease is in the Aizelasi in game is big onshore grow like a weed, low level player cannot receive treatment in time, the player loves do the job, search treasure and dozen wait for daily activity quite cannot on the rails, blizzard because this faces a large number of criticism.

由于疾病在游戏中的艾泽拉斯大陆上迅速蔓延，低等级玩家无法及时得到治疗，玩家喜爱的做任务、寻宝和打怪等日常活动无法正常进行，暴雪因此面对大量批评。
