We research about Japanese sparkler 'senkoh-hanabi' combustion under microgravity. Present 'senkoh-hanabi' studies report only qualitative analysis. Then we develop method of quantitatively analyze about 'senkoh-hanabi'. This method can show 'senkoh-hanabi' spark distribution by integrating video image. Using this method; we clear 'senkoh-hanabi' spark distribution is symmetry around fire ball.
Microwave emission was found when materials were destroyed by a static pressure. This paper describes the experimental setup to observe the phenomena, the obtained terms and results and the method to convert to power. According to the obtained experimental results, the cause of microwave emission is inferred to be the dissociation of atoms or molecules, but is not yet completely confirmed. Currently, the phenomenon is expected to be applied to geophysical explorations in the earthquake detection.
