| Abstract: | A totally-enclosed experimental facility for experiments involving toxic, noxious, inflamable or explosive materials has been designed. In this thesis, to counter the shortcoming that the facility is complicated and is difficult to be mastered, the authors have improved the facility and made it simple and convenient. A facility auto-preventing the liquid from flowing backward has also been designed . The longstanding problem of liquid backward flow in the experiment has got resolved. |
