Two-phase flow and evaporation heat transfer in climbing film flow pumped by steam nozzle were studied experimentally in a transparent electrically-heated quartz tube. 本研究包括对蒸气喷射升膜流动状态的观测和恒热通量条件下喷射蒸发传热的实验研究。
The air having been pumped out, the tube is reduced to a vacuum. 空气抽出后,管子已处于真空状态。
Technical problems in compounding the pumped high-property concrete filled steel tube are stated. 阐述了配制高性能泵送式桥梁钢管混凝土需要解决的技术问题。
Transient temperature rise in a repeat pulse pumped solid-state laser tube 重复脉冲泵浦管状固体激光器的介质温升
A CW optically pumped FIR waveguide laser with gold-coated glass tube 连续波光泵远红外玻璃镀金波导激光器
Preliminary Research on the Compound of Pumped High-property Concrete Filled Steel Tube in Bridge Building 高性能泵送式桥梁钢管混凝土配制的初步研究
Research purposes: Based on the steel tube concrete construction of Yanyan Yellow River Bridge, the research was made on pumped lift-up steel tube concrete in order to solve the difficult problems in steel tube concrete construction. 研究目的:根据雁盐黄河大桥钢管混凝土施工,对泵送顶升钢管混凝土进行研究,解决钢管混凝土的施工难题。
