说明：  一般的IE浏览器并不支持java Applet，运行java Applet只需浏览器关联jre，安装程序后不需任何配置就可以在IE浏览器上体验强大的java Applet的功能。
(General IE browser does not support java Applet, the browser simply running java Applet associated with jre, install the program without any configuration in the IE browser to experience strong java Applet function.)
