Moreover,in this dissertation,a method ispresented to control safe basin with the fractal erosion,that is by the application ofthe weak parameter periodic perturbation with an optimal frequency to control thefractal erosion basin,and the analytical study shows that the essence of the methodis that the parameter periodic perturbation can be used to delay the occurrence ofhomoclinic tangencies.

并且在本文提出了一種對(duì)分形侵蝕安全域進(jìn)行控制的方法，那就是應(yīng)用具有最優(yōu)頻率的參數(shù)周期擾動(dòng)對(duì)于已受到分形侵蝕的安全域加以控制日韩一级毛一片欧美一级ww，在理論分析中得到這種控制分形侵蝕安全域的方法實(shí)質(zhì)上延緩了鞍點(diǎn)同宿相切的發(fā)生国产精品JIZZJIZZ，同時(shí)考慮了外加噪聲對(duì)控制后安全域的影響，得到這種控制方法具有很好的魯棒性黄色片黄色的视频。

The anticlastic curvature caused by bending is 1700 times as long as the sagittal curvature, and the incident angle error is only 2.2 μrad. The Von Mize stress on the bender is about 806 MPa. When Beryllium-Cu is selected as the material of the bender, the linear relationship between the curvature of crystal in 0.57~1.72 m and the driving forces in 8~2.67 N is obtained.
