The function is not good , the pump rotation rate is partial to height since device system operation is unreasonable and the pump entrance vapor erodes, that the vapor erodes , the vapor erodes the entry occurrence part in the pump the day afer tomorrow happened , is able to have air bubble in the water, that it may pound machinery on one hand seals off the outside surface soft and floury , makes it's surface damage appear on; That another aspect may make fitting that astiring sound is encircled by also contain air bubble in flow soft and floury film, can not form the stable flow film , brings about the trunk friction that fitting that astiring sound is encircled by face , makes machinery seal damage.

功能不是很好，泵转速，以高度的部分设备系统运行以来是不合理和泵入口蒸汽侵蚀，侵蚀的水汽，水汽侵蚀入境发生在泵一天afer明天发生，能够有气泡的水，它可以英镑机械密封一方面从外表面柔软，粉状，使得表面上出现的损害，这另一个方面可作出恰当的astiring声所包围也含有气泡流软和粉状电影，不能形成稳定的流动电影，带来的躯干摩擦，恰当的astiring声音所包围的脸，使机械密封损坏。

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种对分形侵蚀安全域进行控制的方法，那就是应用具有最优频率的参数周期扰动对于已受到分形侵蚀的安全域加以控制，在理论分析中得到这种控制分形侵蚀安全域的方法实质上延缓了鞍点同宿相切的发生，同时考虑了外加噪声对控制后安全域的影响，得到这种控制方法具有很好的鲁棒性。
