摘　　要：为了直观地观测流体的流动状况,将所研究的流体对象的流动可视化.根据流体力学相关的理论知识,对采用固体粒子显示气流的跟随特性进行了理论分析,并选用碱式MgCO3白色粉末作为直接投入物,用实验的方法进行了比较和验证.结果表明:直接投入MgCO3粉末来显示气流具有良好的可视性和可记录性,是一种有效的实验方法.By visualizing the fluid object in question, the fluid flow status can be observed directly. According to the relative theory in fluid dynamics, it analyzes the following characteristic of solid tracer elements used to display the air current. The white powder of MgCO3 as tracer elements was directly put into the air stream, and the results of the experiment were compared with those of the theoretical analysis. The results show that it is an effective way to display the air current with powder of MgCO3 as tracer elements directly put into the air stream, and that this method has good visualization and easy track.
