The invention belongs to the technical field of soil remediation, and specifically relates to a method for periodic compound repair of arsenic-contaminated soil, which mainly includes the following steps: transplanting centipede grass to form and prepare a repair layer, and at the same time, electrochemically repair the soil, and harvest after a period of repair Centipede Grass is tested, and according to the test results, it is judged that the repair is completed or the electrochemical repair is performed again or the natural repair is carried out. In the method of the present invention, each step is closely connected, and the cycle mode is judged according to the detection value, so as to avoid unnecessary waste of time and cost; the repair device and equipment are compactly arranged, and the pH of the soil and the electrode chamber is adjusted in real time, and the acid and alkali are adjusted by the automatic control device The ratio of the liquid storage tank is high in stability and flexibility. The cycle mode can be changed according to the test results, and the arsenic is completely repaired, and the final repair can reach more than 98%.

The invention provides a stepless speed change tractor control system and a control method thereof. The control system comprises an engine, a hydraulic mechanical stepless speed changer, a vehicle speed sensor, a traction force sensor, an engine electronic control unit, a speed changer electronic control unit, and a speed changer hydraulic control unit. The stepless speed change tractor control system adopts NT / gT to characterize traction production efficiency-economical efficiency comprehensive optimum at maximum; an optimal speed changing ratio and an engine rotary speed, which meet the traction production efficiency-economical efficiency comprehensive optimum, are calculated through optimizing the speed changing ratio of the speed changer, so that the tractor has good fuel oil economical efficiency under the condition that the relatively large production rate is obtained.

The invention discloses an automatic control method for a transformation process of a supercritical or ultra-supercritical unit from a hygrometric state to a dry state. Currently, the dry-hygrometricstate transformation of a / an (ultra-)supercritical unit mostly adopts a manual operation mode. The technical scheme adopted by the automatic control method is characterized in that firstly a reasonable state transformation node is determined; a theoretical coal feeding amount increment required by a boiler is calculated according to process parameters of stable operation of the unit at a hygrometric state before state transformation; the boiler coal amount is gradually increased according to an optimum coal feeding amount changing rate which is determined through a unit feature test in the state transformation process until the theoretical coal feeding amount increment is reached; and at the initial period of the state transformation, in consideration of the delay feature of the boiler, the water feeding amount at the inlet of a coal economizer is reduced by lowering the water feeding flow, so that the state transformation process is accelerated. By adopting the automatic control method, stable transition of the working conditions in the state transformation process is realized; and the change of the unit parameters is slow, so that abnormal phenomena of equipment failure, overheating of heated surfaces or tripping caused by frequent switching of dry-hygrometric state transformation and acute fluctuation of unit parameters are avoided.

The invention discloses an anti-shaking control method for a container shore bridge hanger. When the hanger is lifted, an anti-shaking controller acquires parameters of trolley speed, trolley position, hanger lifting speed, hanger swing length and hanger swing angle acquired by corresponding sensors and converted in real time, and the anti-shaking controller compares the swing angle of the hangerwith a preset value and performs the following anti-shaking control when the swing angle is greater than the preset value: the anti-shaking controller selects a control model and a swing length representative value corresponding to a judgment interval according to the judgment interval of the hanger swing length or the swing length variation, and the anti-shaking controller calculates the trolleyspeed regulating parameter according to the swing length representative value and the real-time acquired hanger swing angle parameter under the selected control model and then provides a speed regulating signal for a trolley travelling controller to perform trolley acceleration so as to inhibit the swing angle of the hanger to realize anti-shaking control.
