Abstract: The present invention relates to a method for detecting moisture and volatile matter content in raw coal using the value of baseline drift, comprising the following steps: selecting a plurality of types of standard coal having different coal ranks and different ash contents, performing a Raman spectroscopy test and a proximate analysis on each type of standard coal, calculating the value of baseline drift in the Raman spectrum, and setting up the mapping relationship between the value of baseline drift in the Raman spectrum and the characteristic parameters of the moisture and the volatile matter content. The same method and reference are used to perform a Raman spectroscopy test on raw coal to be tested, so as to calculate the value of baseline drift in a Raman spectrum of the raw coal to be tested, and obtain the moisture and volatile matter content of the raw coal to be tested.

Abstract: Disclosed in the present invention are a chalcogenide phase change material based all-optical switch and a manufacturing method therefor, relating to the field of optical communications. The all-optical switch comprises: stacked in sequence, a cover layer film, a chalcogenide phase change material film, an isolation layer film, a silicon photonic crystal, and a substrate. The silicon photonic crystal comprises a nano-porous structure such that the silicon photonic crystal has a Fano resonance effect. When the all-optical switch is used, the state of the chalcogenide phase change material film is controlled by means of laser, and the resonance state of the silicon photonic crystal is modulated to implement modulation of signal light transmissivity; the modulation range is within a communication band from 1500 nm to 1600 nm, thereby implementing an optical switch. The all-optical switch of the present invention has the characteristics of high contrast ratio, high rate and low loss.
