The temperature of flash heating is higher than approximately 1,500 C. Shock wave is considered to be the source of the flash heating. The shock wave may have caused various reactions of co-existing organic compounds during the chondrule formation. It is not well understood what kind of reactions occur on powder sample of organic compounds by flash heating generated with shock wave. Examined were shock wave reactions of powder sample of glycine. Shock wave reaction of single solid ice of aqueous solution of glycine was also examined. The results were completely different between the powder sample and the single solid sample. Although the heating temperature was very heterogeneous for single solid sample, the heating temperature was very homogeneous for powder sample., 資料番号: AA0047898008}, pages = {29--32}, 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 = {Alteration of powder samples of organic compounds by heterogeneous heating with shock wave}, year = {2004} }
