This invention relates to the fields of computer data processing and database technology, specifically to an intelligent search system for business objects based on metadata. The system includes: a context request parsing module: receiving abstract search requests and extracting environment parameters and permission features to generate a dynamic context snapshot; a logical structure construction module: combining snapshot execution rule injection operations to generate a logical abstract syntax tree containing implicit filtering conditions; a multi-dialect compilation and execution module: translating the syntax tree into physical execution statements matching the target storage engine dialect according to physical mapping rules; and an adaptive optimization feedback module: monitoring execution latency data and dynamically correcting the index strategy definition. This invention solves the maintenance bottleneck caused by the tight coupling between business logic and physical storage in heterogeneous data source environments, achieving zero-code modification and hot deployment of business logic.

The present application provides a sunlight-resistant colored electrochemical energy storage fabric based on recycled cotton powder and a preparation method thereof, belonging to the technical fields of flexible electronic textiles and electrochemical energy storage. The preparation method first deposits a TiO2 film on the recycled cotton powder by ALD technology, and then performs mild hydrothermal synthesis to obtain a TMOs@TiO2@CP composite powder with a three-layer nested structure. Among them, the TiO2 film protects the internal recycled cotton powder from erosion during the hydrothermal reaction and is tightly combined with the TMOs functional layer through Ti-O-TM covalent bonds, improving the structural stability and interfacial bonding force of the composite powder. The present application uses the inherent color characteristics of different transition metal oxides to replace traditional black carbon-based materials, endowing the energy storage fabric with rich color choices and meeting the aesthetic and design requirements of high-end textiles. The process route of the present application avoids the damage to the inherent flexibility and structure of cotton fabrics by drastic means such as high-temperature carbonization.

This invention describes a modified silicate-polyurethane two-component grouting reinforcement material, comprising component A and component B, which are mixed in a 1:1 volume ratio before use. Component A, by mass percentage, consists of the following components: water glass: 94%; glycerol: 1%; glyceryl ester compounds: 1%; silane coupling agent: 1%; water: 3%. Component B, by mass percentage, consists of the following components: polymethylene polyphenyl polyisocyanate PM-200: 65%; dibutyl phthalate (DBP): 35%. This invention utilizes the synergistic effect of glyceryl ester compounds and silane coupling agents. The glyceryl ester compounds reduce the interfacial tension between the aqueous and oil phases and promote the uniform dispersion of the silane coupling agent. The silane coupling agent forms a chemical bridge between the inorganic and organic phases, enabling the originally incompatible aqueous and oily agents to form a homogeneous and compatible system. The resulting solidified body has a compressive strength of 24.6 MPa and a bond strength of 3.8 MPa, making it suitable for seepage prevention and sealing in underground engineering and for surrounding rock reinforcement.
