1. Sometimes do not know what they were doing, as if the purpose of uncontrolled indulgence myself. 有时不知道自己在干什么，仿佛是漫无目的的放纵我自己。
2. By doing so, you can prevent the uncontrolled consumption of valuable system resources such as CPU time. 进行限制后，可以防止用户对重要系统资源（例如CPU时间）的不可控的消费。
3. At last, the methods that repress reflection noise in high density, uncontrolled-impedance digital circuit package are given based result of simulation. 最后基于仿真验证结果，给出了高密度、不可控阻抗的数字电路封装中抑制反射噪声的方法。
