Taking the active network as a research task, the input accessibility, the Coates graph of matrix and graph transmission etc are used to analyze the relation between reducibility of the coefficient matrix of the state equation and the electric separability of the network or the electric accessibility of the network for the first time, acquiring sufficient and necessary conditions that coefficient matrix of the state equation is reducible. Network Graph Theory, Matrix Theory and System Theory over F etc are used to derive the structural controllability criterion of the passive network over F for the first time. Then according to these theoretic results, the structural controllability problems of the active network over F are studied, acquiring several structural controllability conclusions of the active network.

Conceiving of battery is that one fills the electricity kettle to full, if capacities are 5000 mAh , this 1000 mA are the machine power consumption, therefore thinking that your note type computer consumes power when for 30 Wh , your battery specification is that 14.4 V , 3600 mAh , you battery sigmatism time is about but , if every sends out the electricity hour with 1000 mA discharging speed therefore approximately 5 hours of battery electricity is finished readjusting oneself to a certain extent right away: 14.4 V * 3.6 Ah/ 30 1.728 hours of Wh =.

想像电池是一装满电的水壶，若容量为5000mAh，若每小时以1000mA的放电速度将电放出，所以大约5小时电池的电就被放完，此1000mA就是机器的耗电量，所以当您的笔记型电脑耗功率为30Wh时，而您的电池规格为14.4V，3600mAh，您的电池的使用时间约为：14.4V * 3.6Ah / 30Wh=1.728小时。
