    Abstract:

    Along with the development of exploration in deep sky research, the stylists pay mote attention to the influence of Lunar dust and Martian dust on spacecraft. In this paper, with the technique of quartz crystal microbalance(QCM), a research of measuring the space fine dust mass accumulation is introduced. A model of adhaesion coeficient betweenthe surface of the quartz crystal pole and the mass of dust particles was establisted. As a result, when the adhesion coeficient is k>m棕02, dust particles accumulation and the frequency of quartz crystal accord with Sauerbrey function. Based onthis theory,by spreading sticky film on the surface of the pole of QCM, fine dust particles mass accumulation can be measured.
