The application relates to the technical field of network security and software testing, and discloses a generative fuzzy testing method for a PDF reader, which has the technical effects of reducing the cost of syntax modeling, improving the coverage of the model, and effectively suppressing the hallucination of a large language model by designing a polymorphic object syntax reduction template and automatically constructing a POG reduction library by combining a retrieval enhancement generation technology; wherein the POG template encodes the complex semantics of the PDF specification into a machine-interpretable structured skeleton by introducing inheritance, polymorphism and dynamic generation instruction fields; the RAG technology combines the specification text, the table and the prior knowledge of the large model to automatically extract accurate object definitions from the ISO standard document; and finally, the POG reduction library with high coverage and high fidelity is constructed by combining the breadth-first iterative extraction and manual checking, thereby fundamentally solving the problems of high cost of traditional manual modeling, poor structural consistency of the deep learning method and hallucination caused by direct generation of the large language model.

This invention discloses a method for automatically generating evidentiary documents for a document management system manual. First, the chapter requirements of the evidentiary document to be generated are obtained, and relevant knowledge is retrieved from a corpus containing ISO standard texts, organizational background documents, and historical evidentiary documents. A chapter-entity-relationship knowledge graph is constructed by parsing ISO standard clauses. A three-level progressive retrieval strategy is used to match specific instance information from the corpus, and the standard requirements and instance information are integrated to generate dynamic prompt words. After generating preliminary content using a large language model, a multi-level rule-based verification system is used to verify grammatical format, standard compliance, and organizational adaptability layer by layer. If a verification fails, a feedback loop is triggered for correction. Key corpora are stored on a blockchain to ensure the traceability of the generated content. Finally, revision opinions from reviewers are obtained and feedback is used to optimize the generation strategy. This invention achieves automated and compliant generation of evidentiary documents, significantly improving generation efficiency and content quality.

This invention discloses a special silica sand for cement strength testing, belonging to the technical field of standard materials for cement performance testing. It is suitable for non-ISO method cement mortar strength testing, requiring no additional components and made solely from natural siliceous mineral particles through physical processing. This silica sand achieves uniform performance through precise control of chemical composition, continuous three-gradation particle design, physical properties, and stability indicators, relying on a fully physical preparation process, thus avoiding the defects of existing technologies and the limitations of ISO standards. Through quantitative indicators and dedicated testing methods, it optimizes particle sphericity, surface roughness, and packing characteristics, improving the interfacial bonding force with cement paste and the density of the mortar. This invention solves the problems of large testing deviations, poor adaptability, and unstable performance of existing silica sand, making it suitable for testing various grades of cement, significantly improving the accuracy and repeatability of test results, facilitating industrial production and control, and showing broad application prospects.
