1·High conductivity and gas tightness are the basic requirements for bipolar plate materials.
高电导和气密性是双极板材料需有的基本性能。
2·The gas tightness of the sealing mechanism is effectively guaranteed through the design of the sealing mechanism.
通过以上密封机构的设计，有效保证了其密封机构的气密性。
3·Gas tightness and water tightness ensure Goldcommon door and window system to produce healthy and comfortable living conditions.
柯曼门窗系统创造健康、舒适的居住环境，离不开优良的气密性和水密性。
4·One of the fundamental measures to simplify a boiler enclosure and to improve its gas tightness is to use the welded broad-fin tube wall construction.
