Abstract
A theoretical relationship which expresses an oscillation frequency sh ift of an AT cut quartz resonator caused by adhesion of spherical part icles in a liquid is derived in terms of material parameters of the li quid and the quartz. The relationship is composed of two terms; one is related to a fluid-mechanical drag, and the other is related to a for eign mass attachment which is expressed by the intrinsically same form as Sauerbrey's formula. The latter contribution to the shift is much smaller than the former one. The theoretical equation has well agreed with the experimental data.
