The invention discloses a vapor chamber having support posts with an inner-sintering structure. The vapor chamber is characterized in that: upper cover plate sintering capillary wicks and lower cover plate sintering capillary wicks are arranged in a cavity between an upper cover plate and a lower cover plate, a plurality of support posts and a plurality of stress absorption rings having a sinking structure are distributed at the inner bottom of the lower cover plate, the upper cover plate sintering capillary wicks and the lower cover plate sintering capillary wicks are provided with a plurality of mounting holes through which the support posts penetrate; and a plurality of bosses which are naturally formed during sintering, and correspondingly matched with sinking positions of the stress absorption rings are distributed on the lower surface of the lower cover plate sintering capillary wicks. The vapor chamber has the advantages that: the stress absorption rings of the vapor chamber can effectively absorb deformation; the regional support post distribution eliminates the influence of the support posts on the enhanced boiling structure of the lower cover plate; capillary porosity wicks in the support posts shorten the refluxing path of liquid working medium in condensing section, separate raising vapor generated by enhanced boiling and reflux falling liquid working medium in the vapor chamber, avoid a shearing effect generated by the contact between a vapor interface and a liquid working medium interface and improve heat-transfer capability.

The invention relates to a land soil improver, especially a green land soil physical property improver and its use method, which mainly includes the following components: organic waste compost, wood biochar, rice husk ash, coconut peat, attapulgite powder With microbial bacterial agent, the volume percentage is: organic waste composting: woody biochar: rice husk charcoal: coconut bran: attapulgite powder=40~55%: 2~4%: 2~4%: 2~4%: 0.5 ~1%; the present invention utilizes organic waste resource products, organic and inorganic materials, microbial agents and other materials to scientifically formulate a green space soil physical property improver according to a certain proportion, aiming at lawns, tree and shrub planting holes, road green belts, etc. Different types of green space habitats, combined with microbial agents, can effectively improve the degradation of soil physical properties such as green space soil bulk density, air permeability, infiltration rate, aggregate structure, and non-capillary porosity, and have a good long-term effect on the growth of green space plants The role of promotion is to improve the sustainability of green space ecological functions.

The invention provides a disaster warning method and system based on a hydrological connected structure index. The method comprises: dividing a target region into a plurality of grid regions, and obtaining a relative volumetric moisture content corresponding to each grid region by measuring the volumetric moisture content of the surface soil of each grid region and the non-capillary porosity; obtaining at least one connected region according to the relative volumetric moisture content corresponding to each grid region, and calculating a ratio of a total area of all connected regions to a totalarea of the target region as a first target index; adding the distance between each two grid regions in the connected region for any connected region, and obtaining the total distance corresponding to the connected region, and adding the total distance corresponding to all connected regions to obtain a second target index; performing disaster warning for the target area according to the first target index and the second target index. The method and system can quantify the hydrological connectivity structure, thereby accurately warning the disaster based on the hydrological connectivity structure index.

The invention relates to a drug patch and equipment with heating and cooling functions, and belongs to the technical fields of make-up and skin care products as well as medical equipment. The drug patch and equipment are utilized for nursing or treatment of the chest, abdomen, face, elbow joints, knee joints and several other parts of a human body. The equipment comprises the drug patch, a heating and cooling device, a DC power supply device, a feeding device and an intelligent control device, wherein the drug patch comprises two or more layers of closed film bag-shaped patches; closed channels are formed in the drug patch; a quick connector B is arranged at the lower end of the drug patch; tiny capillary porosities are formed in both the closed channels and the closed film bag-shaped patches; a drug can be separated out through the tiny capillary porosities, and permeate into a corresponding part of a user; a plurality of bulges are arranged on the drug patch and have a massage function, so that the drug using effect of the drug patch is improved. The drug path and equipment are rapid in cooling and heating, free of noise and low in energy consumption; through adoption of the drug patch, skin pores can be expanded or shrunk, so that the drug can be sufficiently absorbed, and the nursing or treating function of the drug can be more obvious.
