VC实现自动关闭计算机

构和类又非常多的相似之处，如结构可以实现界面，和可以拥有和类一样的成员。结构与类也有一些重要的区别：结构是值类型，而不是引-conformation and category there are many similarities, such as the interface structure can be achieved, and can have and the members of the same category. The class structure are some important differences between the two : the structure is the type of value, rather than primers

驱动升压转换他关键原理是电感的倾向抗蚀电流变化通过创建和销毁的磁场。在升压转换器中，输出电压总是比输入电压高。升压功率级的示意图示于图1。（a）当所述开关被关闭时，电流通过产生的磁场流过电感器的顺时针方向和电感器存储一定的能量。电感器的左侧的极性是正的。（b）当所述开关打开时，电流将被减小的阻抗较高。先前产生的磁场会被破坏，保持朝向负载的电流。因此，极性将被反转（意味着电感器的左侧现在将是负的）。其结果是两个源将在串联导致更高的电压，以将电容器通过二极管D充电
