氷の昇華、小さな構成グレイン上への粒子の破壊、吸収、複素屈折率、そして光の波長程度のサイズを持つ不規則形状粒子による光散乱における充填密度の影響に関して研究を行なった。ダストを形成している彗星ジェットとcircumnuclear haloesの物理パラメーターを明らかにする事を目的に得られた結果を彗星へ適用した。

In China, in recent years, the size of particles, absorption, refractive rate of complex elements, and the degree of optical wave length are highly dependent on irregular-shaped particles, dispersion of light, filling density research and so on. The result of the formation of a comet is that of the comet, the circumnuclear haloes, the physics, the physical, the, the.
