摘要：This study shows the results of field experiments of soil particles saltation and laboratory experiments of imaging of the surface structure of dust particles. In the Gobi area, dust occurs when the wind speed at ground level exceeds 7 m/s. It has been reported that bacteria are attached to dust, but the details of its attachment are unknown. It is also expected that these bacteria will fly at the time of occurrence of dust, and fundamental research is important to clarify the relationship between dust components and bacteria.
