note = {Premixed flames in highly turbulent flow have been investigated by a cyclone-jet combustor. The velocity field has been measured using LDV (laser-doppler velocimeter) to analyze the experimental conditions on the combustion diagram. Especially, the requirement for determination of turbulence scale has been examined. In conventional data-sampling, the interpolated velocity data does include errors so that the auto-correlation coefficient is higher, resulting in the larger integral time scale of turbulence. Slot-Correlation method is useful to examine the velocity fluctuation based on randomly sampled data by LDV. For determining integral time scale, the data number of the order of 10^5 is needed within 10％ error. The flow field is changed by combustion and the turbulence is reduced, with the turbulence scale smaller. On the combustion diagram, the condition of Um < 15 m/s belongs to the flamelet regime, and that of Um > 20 m/s belongs to the distributed reaction zone regime.},
