• To elucidate the extinction mechanism of the flame, further detailed considerations are necessary about the mutual relations among the flame shapes, the hydrodynamic features such as velocity distributions and the temperature characteristics within the flames close to both the upper and lower stability limits, in addition to the results indicated in the preceding reports. From such a view point, the velocity distributions and the axial and radial temperature profiles are minutely measured for three typical flames and two serieses of flames respectively. According to the comparison of the experimental results obtained with each visual flame shape, some special features are found, which seems to be relative to both extinctions at the stability limit and the transition of flame shape. From these results the validity of the excess-momentum radius as a characteristic length of the flame is confirmed, and a step to solve the extinction mechanism is obtained.
