The application provides a method for inducing poly-podophylli rhizoma by using clump buds, comprising the following steps: S1, cutting stem segments from a podophylli rhizoma mother plant, soaking and cleaning to obtain explants; S2, disinfecting and cleaning the explants, inoculating into a clump bud induction medium to obtain podophylli rhizoma clump buds; S3, inoculating the clump buds into doubling liquid I, washing with a liquid clump bud induction medium after culture, and then transferring into doubling liquid II; S4, taking out the clump buds, cleaning, inoculating into a clump bud induction medium, and then inoculating into a bud proliferation medium; S5, waiting until 1-2 cm, screening out potential mutant strains through phenotypes, inoculating into the bud proliferation medium for subculture, and obtaining mutant plants; and S6, rooting culture of the mutant plants, and after root systems grow, planting and raising seedlings, and then poly-podophylli rhizoma plants are obtained. In the research, suitable concentration of colchicine is used for induction treatment twice, and through stage concentration switching and intermittent recovery strategies, the poly-ploid induction efficiency and explant survival are effectively considered.

The application relates to the technical field of disinfection equipment, in particular to an external disinfection cabinet, which comprises a cabinet body with a containing space and a plurality of drawer assemblies arranged in the containing space, and one or more of the drawer assemblies are disinfection drawer assemblies; after the disinfection drawer assemblies are pulled out of the cabinet body, disinfection tubes are exposed outside the containing space; the disinfection drawer assembly comprises a drawer part, sliding parts are arranged at the two ends of the drawer part, and a plurality of disinfection tubes are arranged on the drawer part; the disinfection tubes are arranged on the drawer part and irradiate the outside of the drawer part. The external disinfection cabinet can not only disinfect kitchenware and tableware stored in the cabinet, but also disinfect the environment outside the disinfection cabinet.

This invention relates to the field of pharmaceutical technology and discloses a novel freeze-drying process for the self-assembled peptide RADA16. This process addresses the problem that existing freeze-drying processes cannot achieve the ideal fluffy powder state for the self-assembled peptide RADA16. By optimizing the temperature, time, and operation methods of each step (pre-freezing, first-stage annealing, second-stage annealing, and freeze-drying), the freeze-dried self-assembled peptide RADA16 exhibits a fluffy powder state with significantly reduced internal moisture content, high long-term storage stability, and no impact on its basic properties. The novel freeze-drying process for the self-assembled peptide RADA16 provided by this invention shortens the freeze-drying time, improves product quality, and is suitable for the industrial production of the self-assembled peptide RADA16.

The utility model belongs to the technical field of range hoods, and particularly relates to a kitchen range hood which comprises a range hood body, a protective cover is fixedly connected to the bottom of the outer side wall of the range hood body; a plurality of first supporting columns are fixedly connected to the inner side wall of the protection cover. An oil net is fixedly connected to the outer side wall of the first supporting column; the bottom of the outer side wall of the protection cover is fixedly connected with a sliding groove. The inner side wall of the sliding groove is in sliding contact with a collecting box. The length of the sliding groove is half of the length of the collecting box. A second supporting column is fixedly connected to the inner side wall of the range hood body; the outer side wall of the second supporting column is in sliding contact with a connecting block. A cleaning plate is fixedly connected to the bottom of the outer side wall of the connecting block; the cleaning plate is in contact with the inner side wall of the collecting box; and by arranging a cleaning plate and a first threaded rod, oil stains adhered to the inner side wall of the collecting box are cleaned and scraped, the phenomenon that a user needs to use a brush and the like for secondary cleaning due to oil stain adhesion when the user pours the collecting box is reduced, and the time spent by the user in pouring the oil stains is shortened.

The application discloses basalt fiber-based strong penetration ceramic tile glue and a preparation method thereof. The ceramic tile glue comprises the following components: 40-60 parts of Portland cement, 50-80 parts of quartz sand, 0.5-1.5 parts of basalt fiber, 5-15 parts of redispersible latex powder, and 2-5 parts of water-retaining agent. The basalt fiber is subjected to phosphatization treatment on the surface. The redispersible latex powder comprises siloxane-modified vinyl acetate-ethylene copolymer and long-chain alkyl grafted polyvinyl alcohol at a mass ratio of 3-4:1. The siloxane-modified vinyl acetate-ethylene copolymer is prepared by free radical copolymerization of vinyl acetate-ethylene copolymer and alkenyl siloxane compound at a mass ratio of 100:3-6. The application aims to solve the problems of low bonding strength and easy hollowing and falling of the existing ceramic tile glue in a high-humidity environment.

The application discloses a kind of electroplating production line unloading link multi-carrier plate grabbing timing dynamic scheduling method, comprising: based on the expected time of carrier plate completion electroplating priority ordering, generate initial grabbing priority list;Using shortest path priority rule planning conflict-free grabbing order, obtain optimized grabbing timing sequence;Combining mechanical arm action time and moving time, judge and eliminate the time overlap or space interference of adjacent grabbing action;According to the execution grabbing timing sequence, assign initial unloading position to each carrier plate, so that mechanical arm can place carrier plate with the shortest moving distance after grabbing, generate unloading position mapping table;The execution grabbing timing sequence and unloading position mapping table are matched, and the mechanical arm execution instruction sequence is generated.The application can realize seamless connection and efficient flow of multi-carrier plate in unloading link, reduce mechanical arm empty running and waiting time, reduce carrier plate retention risk, improve the overall operation efficiency of electroplating production line.

This application discloses a method, device, equipment, storage medium, and program product for tunnel flooding early warning, relating to the field of tunnel early warning technology. The method includes: based on a simulation model, determining the tunnel passage time required for vehicles to pass through the tunnel when the tunnel flooding level reaches the maximum flooding threshold; calculating the current flooding level and the current congestion level to determine the current tunnel early warning level; if the current tunnel early warning level reaches the pre-alarm level, determining the maximum flooding warning time when the tunnel flooding level reaches the maximum flooding threshold using the simulation model; determining the actual warning time based on the difference between the maximum flooding warning time and the tunnel passage time; and deducing the flooding level corresponding to the actual warning time based on the simulation model; and issuing a final alarm when the tunnel flooding level reaches the warning level. This application improves the accuracy of tunnel early warning.
