通过模型实验，对大空间中强热源诱导含尘气流（即二次扬尘）控制问题进行了研究，研究发现，采用抽吸气流的全面通风控制二次扬尘是可行的，找出了最佳排气罩形式、安装高度和最佳排风量。为类似工程的设计提供了实验和理论依据，并为相关的设计手册提供了基础数据。
Through the model experiment, the control of the dust-containing gas flow (ie secondary dust) induced by the strong heat source in large space was studied. It was found that it was feasible to control the secondary dust by the full ventilation of the suction gas flow, Gas mask form, installation height and the best exhaust volume. It provides the experimental and theoretical basis for the design of similar projects and provides the basic data for related design manuals.
