Continuous spray lawn nursery method
The invention pertains to the environmental protection technical field, and in particular relates to a continuous silk spraying vegetation method. The continuous silk spraying vegetation method is applied to a high and steep rock slope for the construction of vegetation layers. The invention is characterized in that the vegetation layers are formed by the continuous and synchronous spraying on bacteria soil base materials and long woven silks under high-pressure air, and the bacteria soil vegetation layer is provided with mutually entangled fiber meshes. The overlaying of a fiber net and the bacteria soil layer enhances shearing strength and dynamic stress resistance, which can closely and firmly contact with rock surfaces and enhance the anti-erosion performance, thus effectively preventing the failure of slope protection caused by rainwater erosion. The base material is bacteria soil containing compound microbial bacterial fertilizer, wherein, the compound microbial bacteria can activate the soil, promote the growth and extension of roots, organically integrate with the fiber net and the bacteria soil, realize interception, promote precipitation, achieve water conservation and prevent water and soil erosion.

According to the Lenz's law mis-unplugging prevention socket for the illumination lamp, through cooperative use of a second electromagnet and a coil, when a plug is inserted into the socket, the second electromagnet is in a power-on state, magnetism generated at the top of the second electromagnet is an S pole, and when the socket tends to be separated, the coil and the second electromagnet attract each other according to the Lenz's law. And the plug is effectively prevented from moving towards the top, so that the effect of preventing mistaken pulling is achieved.

The invention discloses a preparation method of a graphene oxide coating metal laminated composite material. The method includes: dripping graphene oxide on the surface of a metal sheet, then carryingout vacuum drying treatment to obtain a metal sheet with a graphene oxide coating, then putting the metal sheet with a graphene oxide coating in a spark plasma sintering furnace, and conducting lamination and sintering treatment sequentially, thus obtaining the graphene oxide coating metal laminated composite material. According to the invention, by conducting lamination and sintering treatment on the metal sheet with a graphene oxide coating in a spark plasma sintering furnace sequentially, the graphene oxide coating and the metal sheet can generate a carbide under high temperature and highpressure conditions, so that the graphene oxide coating and the metal sheet can be tightly combined, thus realizing the structural function integration and high densification of the graphene oxide coating metal laminated composite material, and overcoming the defect of complex interface combination of conventional lamellar structure materials.
