Abstract: The present disclosure relates to the technical field of culture materials for fungi and provides a solid medium for Coriolus versicolor, and a preparation method and use. Bran is used as a main component in the solid medium, and has advantages in economy and environmental protection, and provides high Coriolus versicolor growth rate and strong contamination resistance. The solid medium avoids the tendency to contamination of current media during an experimental process, and reduces culture cost. The solid medium provides higher biomass and stronger contamination resistance than a potato dextrose agar (PDA) medium.

Abstract: The Invention discloses a self-supplied hydrogen fuel cell system and a working method thereof, the system comprising a diesel tank, a gas separator, a fuel cell, a low-temperature separation reactor, a high-temperature separation reactor, an auto-thermal reformer, a water tank and a catalytic burner; With the high-temperature separation reactor, the low-temperature separation reactor and the auto-thermal reformer, diesel is cracked into H2 and CO; as the fuel for the fuel cell, H2 may react with O2 in the air and generate electric energy; the unreacted H2 and CO enter into the catalytic burner for combustion, ensuring that the water is heated; thus, it not only provides H2 to the fuel cell, but also provides high-temperature water to the auto-thermal converter to produce H2; electric energy can be generated without burning diesel; since no NOx or particulate matters but CO2 is generated, the goal of ultra-low emission is achieved.

Abstract: The present invention provides a cold-storage instantaneous heat pump water heater (HPWH). The HPWH includes a cold-water tank, a main evaporator, a compressor, and a hot water heat exchanger. In the present invention, heat of a working medium in the cold-water tank is absorbed by the main evaporator, and bathing water is rapidly heated by the hot water heat exchanger (condenser of the heat pump), thereby realizing instant heating with small input electrical power. Cold-water tank replaces the hot water tank of conventional HPWH avoiding energy loss during hot water storage. The working medium in the cold-water tank absorbs heat from the environment, to further improve energy utilization. In addition, there are three energy recovery evaporators to recover the waste heat of bathing.

Abstract: A method for recognizing polluted seawater areas based on high-resolution remote sensing images includes performing automatic sea and land classification on a remote sensing image by using a supervised learning algorithm. The classification result reaches a higher precision level by processized iterative clustering compared to conventional methods. The method further includes combining a chlorophyll-associated normalized difference vegetation index, a brightness-associated normalized difference water shadow index, a segmentation-based image interpretation thought and a human visual saliency-based mechanism in remote sensing interpretation by virtue of a chlorophyll concentration difference of a seawater polluted area and surrounding seawater and a brightness difference of pollutant shadows. The seawater polluted area is extracted by threshold segmentation. An area where the water quality is good and a heavily polluted area are extracted. A pollution transition area is further extracted. The method provides convenience and an accurate reference for prevention and control of marine pollution.
