| Abstract: | Based on multiwavelength Pyrometry, a detonation temperature measuring system is presented. The spectrogram of detonation′s radiation and of the standard lamp can be acquired to computer by spectrometer and gated ICCD system, respectively. The detonation temperature as well as the spectral emissivity can be calculated by applied the regression analysis method to the spectral ratio of the spectrum. Experimental results of the detonation temperature, the spectral emissivity of the liquid explosive Nitromethane(N.M.)are given. The methods about how to reduce the measurement errors are also fully discussed in particular. |
