Micro-raman spectrum testing method for crystal quality evaluation of single-compound explosive

The invention relates to a micro-raman spectrum testing method for crystal quality evaluation of a single-compound explosive. The method comprises the following steps of: randomly selecting 6-12 single-compound explosive particles and placing on a slide of a laser confocal raman spectrometer; focusing by using a long-focus objective of 50 multiples, performing full-spectrum scanning on the single-compound explosive particles with laser wavelengths within wavelength ranges of 785 nm and 2,000-400 cm to obtain a raman spectrum of the single-compound explosive particles and selecting peak with high raman strength and without interference between spectral peaks as a characteristic spectral peak; and performing static scanning on the characteristic raman peak within a laser attenuation range of 1-100 percent in order to prevent possible damage caused to a crystal microstructure of a test piece by a laser thermal effect, performing static scanning on the characteristic spectral peak while determining that peak
