摘    要：用试验方法分别测定了含 NaCl,CaCl₂,MgCl₂3种卤化物的粉尘试样在自然环境中昼夜周期吸湿、放湿的行为,并统计分析了试样吸湿率与吸湿剂含量、空气中的温度、湿度 等因素之间的关系.其研究结果对卤化物抑制路面、地面和各种散体堆放场等的扬尘具有重要的实际意义.

Abstract: In this paper, dust was compounded with solid NaCl, CaCl₂ and MgCl₂ respectively according to different designed contents. These prepared samples were put in a group of evaporation pans and laid barely in atmosphere. The water absorbing rate in the samples was tested every day in a whole year under variable climate conditons. Based on a great number of achieved data and the statistic method, the periodic behaviour on water absorbing and releasing during day and night and the relationships among water absorbing rate, air temperature,humidity and chloride content, etc., in the samples were fully investigated. These research results are very significant for the chlorides to be used in controlling dust pollution in many fields, such as roadway, construction site, and large open bulk material stores, etc.
