 note = {In protoplanetary disk, dust grains grow through mutual collisions, gradually settle to the midplane of a disk. This process is initial condition of planet formation and it is very important process. In many of previous work, they assume that collisional fragmentation do not occur. In fact, the collisional fragmentation make small fragment and suppress the growth of dust grains. The outcomes of collisions are governed by collisional velocities. In this study, we examine the collisional velocity in the way of dust growth to clarify whether collisional fragmentation of dust grains occurs in protoplanetary disks or not and where collisional fragmentation occurs, as the first step of the development of the dust evolution model taking into account fragmentation., 資料番号: AA0063350010},
