Abstract: The present invention provides a method for realizing high stability of micro-nano optical fiber sagnac loop output by means of filter mode control, and belongs to the field of photoelectric detection technologies. In the present invention, the optical filter is combined with the micro-nano optical fiber Sagnac interference structure so as to control the Sagnac in-loop working mode by use of the mode selection characteristics of the filter. In this way, the interference mode is suppressed to better concentrate energy on the working mode, thereby improving the spectrum output uniformity and stability of the Sagnac loop. Further, the reflection and transmission modes of the optical filter do not participate in interference spectrum output and thus the performance of the system will not be affected. By designing and changing the parameters of the optical filter, the output characteristics of the interferometer can be dynamically controlled.

Abstract: The invention relates to a method for person re-identification based on deep model with multi-loss fusion training strategy. The method uses a deep learning technology to perform preprocessing operations such as flipping, clipping, random erasing and style transfer, and then feature extraction is performed through a backbone network model; joint training of a network is performed by fusing a plurality of loss functions. Compared with other deep learning-based person re-identification algorithms, the present invention greatly improves the performance of person re-identification by adopting a plurality of preprocessing modes, the fusion of three loss functions and effective training strategy.

Abstract: An aircraft Ultra-High-Temperature Sterilization Air Conditioning System (UHTS-ACS) and a sterilization method are provided. An ultra-high-temperature sterilization recirculated air device is added on the basis of a traditional aircraft air conditioning system. The recirculated air device includes an ultra-high-temperature sterilization recirculated airline (9), a heater (26), a high-temperature injection mixing chamber (27) and a primary heat exchanger (12) bypass. The recirculated airline is connected to the high-temperature injection mixing chamber (27). After being mixed with high-temperature engine bleed air (I) under the injection action of an injector (28), the mixed high-temperature gas enters a compressor (15) through the primary heat exchanger (12) bypass to be compressed and heated, is regulated to a suitable temperature through cooling of a secondary heat exchanger (13) and a turbine (16), and then is supplied to an aircraft cabin.
