The invention belongs to the technical field of bearing materials, and discloses vinyl hyperbranched polysiloxane, a polyvinyl composite material bearing and a preparation method.The preparation method of the vinyl hyperbranched polysiloxane comprises the following steps that a first siloxane monomer containing at least four vinyl groups and a second siloxane monomer containing sulfydryl are mixed, then adding a photoinitiator, uniformly mixing, and performing ultraviolet irradiation to obtain an intermediate; and slowly dropwise adding an aqueous medium into the intermediate, adding a catalyst at the same time, and then reacting at 60-90 DEG C for 4-8 hours to obtain the vinyl hyperbranched polysiloxane. According to the invention, an efficient and mild vinyl hyperbranched polysiloxane synthesis system is constructed, and the controllability and storage stability of the product structure are improved. According to the invention, high-efficiency compatibility of inorganic filler and a polyethylene matrix is realized by virtue of the synthesized vinyl hyperbranched polysiloxane, and the comprehensive performance and service reliability of the polyethylene-based composite material bearing are greatly improved.

The invention discloses a natural person identity encryption real-name authentication method and system, and relates to the field of identity and data security. The method is based on a'natural person-encryption terminal-authentication server 'closed-loop encryption architecture, an identity identifier capable of directly recognizing a natural person is not collected, and the core comprises five steps of information collection, authentication initiation, identity authentication, dynamic identity password generation, closed-loop verification and result synchronization. The system adopts a three-level distributed architecture and is composed of an encryption terminal and an authentication server, and the encryption terminal and the authentication server cooperate to achieve secret key fragmentation management, encryption communication and auditing tracing. According to the method, the principle of minimum necessary collection is followed, the national secret algorithm, secret key fragment storage and block chain evidence storage technology are combined, identity authentication is unforgeable, uncounterfeitable and traceable, sensitive information leakage is eradicated from the source, compliance cost is reduced, the method is adaptive to multi-field and multi-terminal scenes, related laws and regulations are met, and high safety and practicability are achieved.

The invention relates to the field of petrifaction, and discloses a green refining method of crude caprolactam, which comprises the following steps: S1, mixing crude caprolactam with a crystallization solvent, carrying out primary crystallization, carrying out solvent removal, heavy component removal and light component removal on a primary mother solution obtained by separation, mixing the recovered solvent and caprolactam with crude caprolactam, and recrystallizing; or removing the solvent from the primary mother liquor, recovering, concentrating, performing secondary crystallization, and separating to obtain secondary crystals and secondary mother liquor; carrying out solvent removal, heavy component removal and light component removal on the secondary mother liquor, mixing the recycled caprolactam with the primary mother liquor for secondary crystallization, separating to obtain secondary recycled crystals, mixing the secondary recycled crystals with secondary crystals and crude caprolactam, and then carrying out primary crystallization again; and S2, adsorption refining. According to the method disclosed by the invention, efficient and green refining of the crude caprolactam can be realized, the finally obtained caprolactam has high purity, low chroma and high yield, and the method has obvious advantages in production of high-end caprolactam products with extremely high chroma requirements.

This invention addresses the problems in existing transmission tower leg landslide monitoring technologies, such as difficulties in sensor deployment, poor long-term reliability, difficulty in capturing system-wide coordinated deformation, and a disconnect between monitoring data and structural stability assessment. It proposes a method for identifying the slippage state of transmission tower legs based on tension monitoring data. The method includes: determining the soil parameters at the site of the transmission tower; performing frequency domain signal analysis on the collected cable tension signals to obtain the static cable tension value; and inputting the static cable tension value into a mapping relationship between static cable tension and leg landslide amount to obtain the leg landslide amount. This method achieves direct monitoring of leg slippage by constructing a mapping relationship between static cable tension and leg landslide amount.
