Abstract: Embodiments of the present disclosure disclose a class file processing method and apparatus, a device, a medium, and a product. The method includes: obtaining respective anonymous inner class files generated after performing class file merging and compiling on respective class files in an AAR file of a target application program, and parsing file name identifying information of the respective anonymous inner class files; determining associated code resource bundles of the respective corresponding anonymous inner class files based on parsing results of the file name identifying information; and in response to that the associated code resource bundle of one anonymous inner class file is inconsistent with a code resource bundle where the one anonymous inner class file is currently located, dispatching the one anonymous inner class file into the corresponding associated code resource bundle.

Abstract: Disclosed are a method, an apparatus, a device, a medium and a product for application package generation, wherein the method comprises: acquiring a code resource file of a target application, and parsing attribute information of a code resource in each class file in the code resource file; distributing each class file into a corresponding sub-code resource package in accordance with the attribute information; generating a target application package in a target format based on each sub-code resource package; wherein the code resource file of the target application is an AAR file of the target application program.

Abstract: A spectroscopic analysis device based on Brillouin dynamic grating and its analysis method, which provides high resolution and large measuring range at the same time. The device includes a laser device (1), a fiber optic coupler device (2), a first fiber amplifier device (3), a first isolator (4), a first polarization controller (5), a second polarization controller (6), a single-sideband modulation modulator (7), a second fiber amplifier device (8), a second isolator (9), a third polarization controller (10), a single-mode fiber (11), a polarization beam splitter (12), a circulator (13), a photodetector (14), a data acquisition card (15), a fourth polarization controller (16) and a microwave source (17). The method utilizes the Brillouin scattering of two beams of pump light in optical fiber forming Brillouin dynamic gratings as the spectral element and achieve a sub-MHz resolution.
