利用基于拉普拉斯谱划分的递归二分法将电力网络进行支路切割，然后将支路切割转换为节点撕裂。
By means of Laplacian spectrum recursive bisection partitioning method, firstly the power network is partitioned into branch-cut form; then the branch-cut form is changed into node-split form.
具有阻抗匹配和振幅检测等多项功能，电声转换效率高，发热少，切割速度快。
Because it has many functions such as Impedance matching and amplitude detecting, the system has high electroacoustic transformation efficiency, low heat and rapid cutting ability.
现代科技中，在钢和有色金属转换和生产中会出现切割问题。
Modern technology in the production and converting of steel and non-ferrous metals unfortunately causes cutting problems.
