The application relates to a sodium titanate nanofiber / reduced graphene oxide composite electrode material and a preparation method and application thereof. The composite electrode material has a two-dimensional sheet structure, the particle size is 1-6 mu m, the thickness is 10-20 nm, is composed of a few-layer reduced graphene oxide and sodium titanate nanofibers with a diameter of 5-10 nm loaded on the reduced graphene oxide, and is prepared by taking the few-layer reduced graphene oxide as a template, uniformly loading titanium dioxide particles, and then carrying out hydrothermal treatment in an alkali solution. Compared with the prior art, the synthesis method is simple in process, easy to scale up, and high in controllability. As a negative electrode of a sodium ion battery or a positive electrode of a sodium battery, the sodium titanate nanofiber / reduced graphene oxide composite electrode material has the advantages of high initial coulomb efficiency, low working voltage, high capacity, excellent rate characteristics and cycle stability, and has a broad market application prospect.

The application discloses a high-entropy oxide loaded lanthanum ferrite gas-sensitive material and a preparation method and application thereof, and comprises the following steps: preparing lanthanum ferrite powder; dispersing the lanthanum ferrite powder in water, adding citric acid, and then performing ultrasonic treatment under ice water bath conditions to obtain a surface-modified base suspension liquid; under ice water bath and stirring conditions, dropping a high-entropy complex mother liquor into the base suspension liquid, then adding urea, and performing hydrothermal reaction to obtain a precipitate; washing and drying the precipitate, and then performing stepwise temperature increasing calcination in air. The sensor prepared from the gas-sensitive material has a low baseline resistance of 11 MΩ at an optimal working temperature of 180 DEG C, a response degree of 45.24 to 50 ppm of acetone, and an optimal working temperature which is reduced by 75 DEG C than that of a pure LaFeO3 sensor; the response and recovery times are shortened to 23.38 seconds and 8 seconds respectively, and the sensor exhibits excellent kinetic characteristics.

The invention is applicable to the technical field of building machinery, and provides prefabricated part hoisting equipment and a control system, and the prefabricated part hoisting equipment control system comprises a counterweight control module, a dynamic state observation module, a control module and a control module, and is characterized in that the counterweight control module is connected with the dynamic state observation module; the processor is configured to process the initial height, the real-time swing amplitude, the real-time swing angular velocity and a preset stable threshold value based on a preset counterweight lowering distance control model so as to generate and output a target lowering distance of the counterweight mechanism; wherein the target lowering distance is used for driving the executing mechanism to adjust the vertical position of the balance weight mechanism on the lifting rope so as to restrain swinging of the prefabricated part in the lifting and moving process. According to the prefabricated part hoisting equipment control system, the counterweight control module can be tightly matched with the dynamic state observation module, and fine and self-adaptive adjustment of the position of the counterweight mechanism is achieved through real-time and accurate swing data provided by the counterweight control module.
