The present invention discloses a low dielectric constant filter membrane based on biological enzymes. The preparation method includes drying the low dielectric constant filter membrane, dropping biological enzymes onto the surface of the dried filter membrane and then freeze-drying. After the moisture has completely evaporated, the low dielectric constant filter membrane based on biological enzymes is obtained. At the same time, the present invention also discloses the application of the low dielectric constant filter membrane based on biological enzymes in a waveguide gas sensor. After fixing the low dielectric constant filter membrane based on biological enzymes on the resonance window of the resonator in the waveguide gas sensor, the sensor is assembled and tested. By using a filter membrane with a small volume that is convenient for installation and disassembly, the present invention is conducive to repeatedly testing the same sample multiple times, has good reusability, and the low dielectric constant filter membrane based on biological enzymes has good air permeability, which can enable the enzymes to fully contact with the gas, further improving the sensitivity of the sensor.

This invention provides a linear electronic fence calculation method based on path planning, comprising: obtaining the vehicle's navigation path; setting the basic radius R0 of the electronic fence according to the navigation path; determining each road segment in the journey based on neighboring nodes on the navigation path; and obtaining the positioning accuracy R at each node on the navigation path. x Positioning accuracy R x This represents the positioning error distance of the vehicle's positioning system at the current node due to the influence of the surrounding environment; two circles with radius R are drawn, centered on the two nodes of each road segment. The radius R is the base radius R0 and the positioning accuracy R... x The method involves drawing two common external tangents to two circles on the same road segment. These two tangents, combined with the two circles, form a smooth, pocket-shaped region. Connecting these smooth, pocket-shaped regions end-to-end across all road segments creates a linear electronic fence. This method can quickly generate high-precision linear electronic fences, enabling timely and accurate detection of vehicle deviations.

The application relates to the field of biotechnology, and particularly discloses a mutant strain Cbg61-T37, a co-expression strain Cbg61-T37-MPR1 and a construction method and application thereof. The mutant strain Cbg61-T37 is preserved in the China General Microbiological Culture Collection Center on August 18, 2025, has a preservation number of CGMCC No. 35649, and is classified and named as Pichia pastoris. Pichia pastoris The mutant strain Cbg61-T37 provided by the application has an enzyme hydrolysis activity of 62.9 U / mg, which is increased by 43.8% compared to the original strain. Therefore, the mutant strain Cbg61-T37 is more conducive to catalysis and synthesis of the rare ginsenoside CK.

This invention provides a method for preparing an adsorbent, comprising: obtaining a first raw material, which is ginkgo leaves; pretreating the first raw material to obtain a raw material to be treated; pyrolyzing the raw material to obtain a pyrolysis product; grinding the pyrolysis product to obtain a ground product; obtaining a second raw material; ultrasonically treating the second raw material; reacting it with an alkaline solution to form a precipitate and stirring to obtain a mixture; passing the mixture and the ground product into a hydrothermal reactor for a hydrothermal reaction to obtain a hydrothermal reaction product; and post-treating the hydrothermal reaction product to obtain an adsorbent. This method solves the problem of zirconium oxide's inability to absorb SO4 in the prior art. 2‑ There are issues with the potential for loss during the process and the need to add additional solid-liquid separation equipment.
