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: Provided are an image fusion method and apparatus, an electronic device, and a storage medium. The method includes the following steps: A shooting operation acting on a first page of a target shooting activity is received, where the first page is an H5 page; in response to the shooting operation, a camera is called through system shooting software to collect an original image; a fusion operation for the original image is received; and in response to the fusion operation, the original image is fused with a first target effect, a static target image that includes a static image obtained by fusing the original image with the first target effect and the first description information related to the static image is generated, and the static target image is displayed on a second page, where the second page is an H5 page.

Abstract: Embodiments of the present disclosure relate to a permission setting method and apparatus, a device, and a medium. The method includes: displaying a permission customization control, in response to a trigger operation on a permission setting object of task information, the permission setting object including a first information object and/or a second information object, the second information object being subordinate to the first information object; displaying a permission editing interface, in response to a trigger operation on the permission customization control, and receiving customization permission information via the permission editing interface; and displaying the customization permission information corresponding to the permission setting object. Therefore, a hierarchy structure based on the task information satisfies a setting need for content-based permission customization, and improves a permission management efficiency.

Abstract: Provided is a method for berth allocation of a multiline bus station and speed guidance of buses. The intelligent control center sorts all buses between the current station and the previous station to form the BusNumber table, and performs speed guidance for all buses in the BusNumber table. Whether the guided bus can pass through the signalized intersection is determined. The buses that cannot pass through the signalized intersection are guided by acceleration, and those that cannot pass through the signalized intersection by acceleration guidance method update their speeds based on the phase state of signal light, so as to pass through the signalized intersection without stopping in most cases. All buses are conducted through speed guidance methods, and the berths are allocated for all the buses under different conditions.
