Jsp Struts javascript树形菜单附代码
Jsp Struts javascript树形菜单附代码,号称史上最完美的jsp版树形菜单效果，附有代码和用法说明，基于dtree内核，本过本实例现了动态的树形菜单，就是将树型菜单的节点保存在数据库表中，通过数据访问对象将其从数据库中查出后放在一个集合对象中，并将该集合对象传递给客户端。
当然，在实际项目中，节点的信息往往并不是放在一个单一的表中的。比如：在一个权限管理系统中，这些信息可能分别放在用户表、角色表、功能表等表中，只要设法让查询出来的结果与下面给出的表格的内容相似就可以了。只要稍微有些数据库方面的知识做到这点并不难。

pwm_inverter
说明： 逆变器将直流电转化为交流电，若直流电压较低，则通过交流变压器升压，即得到标准交流电压和频率。对大容量的逆变器，由于直流母线电压较高，交流输出一般不需要变压器升压即能达到220V，在中、小容量的逆变器中，由于直流电压较低，如12V、24V，就必须设计升压电路。(The inverter converts DC into AC. if the DC voltage is low, the standard AC voltage and frequency can be obtained by boosting the voltage through the AC transformer. For large capacity inverters, because of the high DC bus voltage, the AC output can reach 220V without transformer boosting. In medium and small capacity inverters, because of the low DC voltage, such as 12V and 24V, the boost circuit must be designed.)
