Abstract: A battery shell includes a shell body internally provided with an accommodating cavity. At least one face of a shell body facing and/or facing away from the accommodating cavity is provided with heat dissipation recesses, so that the face has a non-penetrating “skylight” structure. The heat dissipation recesses extend in a thickness direction of the shell body without penetrating the shell body. A plurality of heat dissipation recesses are provided in the at least one face of the shell body. All the heat dissipation recesses are arranged at intervals.

Abstract: A method and a system for identifying a glacial lake outburst debris flow (GLODF) are provided. The method is obtained based on considering induced influences of slopes of channels and particle sizes of source particles on the GLODF. The method not only compensates for deficiencies in identifying the GLODF, but also realizes determination of the GLODF, which provides data basis for disaster prevention and control layout such as monitoring and early warning on a glacial lake and assists preventing and managing disasters caused by the GLODF. Meanwhile, multiple parameters used in the method are easy and convenient to obtain, and the parameters can be directly used on site, which saves engineering cost, improves working efficiency, and has high practical and promotional value in environmental protection and disaster prevention and mitigation.
