PYQT5點擊菜單欄彈出新窗口，解決窗口閃退的問題

需要通過self實例化為全局變量，不加self的話，一運行就會被收回，所以無法顯示

    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)
