Spectrum technology in coal quality detection has become a research hotspot with the maturing of spectral technology and the continuous development of spectral imager. This article mainly analyzed and summarized the progress and research status of scholars at home and abroad based on the coal quality index (moisture, ash content, volatile matter, fixed carbon and sulfur content).According to the coal quality index, we demonstrated spectrum technology has considerable prospects in coal quality testing by analysis the application of spectrum technology in detection of other material's corresponding index.

Abstract-Spectral analysis has a very high sensitivity and accuracy, widely used in qualitative and quantitative analysis of textile fibers. This paper described the mechanism of spectroscopy in qualitative identification of textile fibers. Then it gave a systematic review and summary on the research of qualitative or quantitative analysis of textile fibers. It discussed the mechanism of spectroscopy in silkworm cocoon sex identification. And then it summarized the research status of spectroscopy in silkworm cocoon sex identification. It analyzed the existing problems and deficiencies of spectrometry in testing. Finally, it put forward the further research direction of spectroscopy detection and composed out the outlook of the application of hyper spectral in silkworm cocoon sex identification.
