The model is perfect aggregative. When imput of system is more complex than pulse function and jump function, this model provides response more accurately than other perfect aggregation models.
该模型是完全集结，当输入函数比脉冲函数、阶跃函数复杂时，比其它完全集结模型的响应拟合好。

Constructing fast response policing system is a necessary trend of the modem policing mechanism. It should depend on the aggregative advantages of all kinds of police by uniform command.
