 note = {The existence of chondrules indicates that the flash heating events occurred in the early solar nebula. The shock-wave heating model is a plausible model for chondrule formation. In this model dust particles are heated by the gas frictional heating. So it is naturally expected that the dust particle starts melting from surface to inside and a state where the surface of the particle is liquid and the center is solid is realized (it is called the partial melting state in this study). Kato et al. (2005) and Kadono and Arakawa (2005) show that stripping of the liquid surface by the gas flow may determine the maximal size and size distribution of chondrules assuming that partial melting state is realized in a dust particle. In this study, we examined whether or not the partial melting state is realized in the dust particle by solving a three-dimentional time dependent heat conduction equation. We found that the partial melting state is realized in the shock-wave heating model, and especially for dust particles of 1 mm or larger in radius, it is likely that the partial melting leads to the stripping of the liquid surface., 資料番号: AA0063350006},
