Compared to the other functional methods , post - functionallization are more widely researched and applied 與另外兩種功能化方法相比,后功能化法的研究和應(yīng)用較為廣泛。
But some famous jurists such as zweigert and koetz argued that it was not a useful tool for a functional method like comparative law 但在比較法上,對是否規(guī)定法律行為存在很大的爭議。
In the proof , by the subsystem which makes the discussion more convenient , we get more brief sufficient conditions . we also use the comparison theorem , liapunov functional method and razumikhin function method 在以上的證明中,考慮了系統(tǒng)的獨立子系統(tǒng),使問題更加簡單,條件更加簡捷,并且使用了比較原理、 liapunov泛函方法、 razumikhin函數(shù)法。
The results extend those of autonomous systems to case for no autonomous systems . 4 . the stability and the existence of periodic solutions for ecological systems of reaction - diffusion type are discussed by using of smoller invariant domains principle liapunov functional method comparison principle and fixed point theorem 四、研究了用偏微分? ?積分方程描述的生態(tài)系統(tǒng)平衡位置的穩(wěn)定性、漸近穩(wěn)定性及周期解的存在性、穩(wěn)定性,采用smoller不變區(qū)域原理、比較原理,不動點原理及l(fā)iapunov泛函方法。
