PYQT5点击菜单栏弹出新窗口，解决窗口闪退的问题

需要通过self实例化为全局变量，不加self的话，一运行就会被收回，所以无法显示

    def rabbit_talk(self):
        try:
            from asrInterface import Ui_Dialog
			'''要加self'''
            self.Dialog = QMainWindow()
            Ui_Dialog().setupUi(self.Dialog)
            self.Dialog.show()
        except Exception as e:
            print(e)
