We consider nonsteady shock case which is raised by gas clumps infalling on the disk nebula and found ranges of clump mass and size which can make the disk temperature rise to the dust evaporation temperature (about 1,500 K) and corresponding gas heating time. From our obtained relation between clumpy clouds and shock strength, the clumps estimated by some observations seems difficult to rise the nebular temperature high enough for dust evaporation., 資料番号: AA0063352021}, pages = {81--84}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Clumpy cloud accretion on the disk and the chondrule formation}, year = {1995} }
