The present application belongs to the technical field of glass fiber sizing agent, and particularly relates to an anti-creep glass fiber sizing agent and a preparation method thereof. The anti-creep glass fiber sizing agent comprises effective components and water, and the solid content of the anti-creep glass fiber sizing agent is 3-12%. The effective components comprise the following components according to weight percentage: maleic anhydride modified long-chain branched polyolefin wax 65.5-86.9 wt.%, coupling agent 5-10 wt.%, nucleating agent 1-8 wt.%, physical cross-linking component 5-12 wt.%, initiator 0.1-0.5 wt.%, and surfactant 2-4 wt.%. The present application can effectively solve the problem of insufficient anti-creep ability of the glass fiber reinforced polypropylene material in the prior art, and at the same time, the material has good mechanical properties and fatigue resistance, which plays an important role in improving the long-term dimensional stability of the polypropylene material.

This invention provides a multi-scale corn stalk cellulose-reinforced cementitious material and its preparation method. The multi-scale corn stalk cellulose-reinforced cementitious material comprises multi-scale corn stalk cellulose and cement. The multi-scale corn stalk cellulose has both micron-fiber and nanofiber structures. The micron-fibers have a diameter of 1-5 μm and a length of 500-3000 μm, and the nanofiber structures are mainly distributed on the surface of the micron-fiber structures, with a diameter of 1-5 nm and a length of 100-2000 nm. The multi-scale corn stalk cellulose-reinforced cementitious material provided by this application exhibits higher flexural and compressive strengths (10-30% increase) than the control group cement, and has broad application prospects in the field of construction engineering.

The invention discloses water floating type domestic sewage treatment water recycling equipment which is integrated on a floating body platform, and the total occupied area is less than or equal to 3m. The equipment comprises a pretreatment unit, a multi-stage A / O biochemical treatment unit, an intermediate precipitation unit, an MBR membrane deep separation unit, a clear water recycling unit and an intelligent control unit which are sequentially connected in the water flow direction. The biochemical treatment unit forms a high-load bioreactor by adding high-specific-surface-area biological filler; and an immersed ultrafiltration membrane component is arranged in the MBR tank. A trapezoidal rainwater collecting device is arranged at the top of the clear water tank, and intelligent filtering and automatic supplementing of rainwater are achieved through a liquid level sensor and a controller. The system also integrates photovoltaic power supply and mobile phone APP remote control functions, and can efficiently treat domestic sewage and realize cyclic utilization of water resources.

The invention provides a target code auditing method and device, and belongs to the technical field of computers. The method comprises the following steps: acquiring a rule file data set and a knowledge graph structure; generating a syntax tree rule plug-in according to the rule file data set; under the condition that the target code is received, based on the syntax tree rule plug-in and the knowledge graph structure, executing multi-level auditing on the target code to obtain a code auditing score; and determining an execution strategy based on the code auditing score, and processing the target code according to the execution strategy. In this way, multi-level auditing is conducted on the target code based on the syntax tree rule plug-in and the knowledge graph structure to determine the execution strategy, the problem that according to an existing code auditing method, due to auditing rule updating lag, a compliance blind area is caused can be solved, the problem that due to the lack of deep semantic understanding, service logic cannot be effectively verified, and code reuse cannot be effectively promoted can be solved, and user experience is improved. The real-time performance and accuracy of code auditing are improved, and the compliance risk is reduced.
