Abstract: Disclosed are a device of complex gas mixture detection based on optical-path-adjustable spectrum detection and a method therefor, and the device includes: a light source configured for generating an incident beam and emitting the incident beam into an optical gas cell; the optical gas cell, including a cavity configured for accommodating a gas sample, and a reflection module group configured for reflecting the incident beam and a track arranged in the cavity, where the track is consistent with a light path of the light beam in the cavity; a detector module that is connected with the track in a relatively movable manner and is configured for receiving light beams and obtaining spectral data, where an optical path is changed by moving the detector module relative to the track; and a data acquisition unit that is configured for acquiring the spectral data obtained by the detector module.

Abstract: A compressor includes a housing, and an anticorrosive coating covering a surface of the housing. The anticorrosive coating includes a base layer applied on the surface of the housing, and a surface layer applied on the base layer. Both the base layer and the surface layer are organic coatings. Thus, the housing of the compressor is effectively separated from the external environment by means of the two organic coatings, so as to ensure that the compressor is not corroded; moreover, the anticorrosive coating does not contain a metal coating, thereby preventing the problem of the compressor being severely corroded due to an exposed metal coating.
