The application provides a missile engine storage availability evaluation method, namely a missile engine storage availability evaluation method based on a two-stage sampling scheme and historical sampling data, and the implementation steps are as follows: 1, parameter estimation according to historical sampling data; 2, calculation of the two-stage sampling probability of the missile engine; 3, iterative calculation of the instantaneous availability evaluation value of the engine; 4, calculation of the average availability evaluation value of the engine; the application realizes the evaluation of the storage reliability and storage availability of the missile engine without additional experiments, the evaluation value is derived from actual data, has authenticity, accuracy and stability, the iterative method is simple, the requirement for historical data is low, the operability is strong, and not only the average availability of the missile engine can be evaluated, but also the instantaneous availability of the missile engine can be evaluated.

This invention provides a road network-level pavement technical condition detection path planning method, comprising: determining the current mileage marker coordinates corresponding to the road network to be detected based on the number of detection vehicles; determining all detection road segments corresponding to the current mileage marker coordinates based on the current mileage marker coordinates; determining recommended detection road segments from all detection road segments; traversing all remaining mileage marker coordinates, and determining the planned path corresponding to the road network to be detected based on the recommended detection road segments. The road network-level pavement technical condition detection path planning method provided by this invention divides the road network to be detected into several detection road segments with mileage marker coordinates as nodes, and uses these detection road segments as basic traversal units to traverse all detection road segments, ultimately determining the final planned path. This method avoids the drawback of detection vehicles traversing numerous backtracks, reducing detection time and labor costs; furthermore, this method is more scientific and efficient.

The gas-liquid fertilizer mixing system and mixing method belong to the technical field of agricultural equipment, and are composed of a water storage device, a liquid fertilizer generating device, a gas-fertilizer separation device, an electrolysis device and a gas-liquid mixing device. The corresponding salt solution and acid are put into the liquid fertilizer bin to generate ions and carbon dioxide. The water tank is communicated with the liquid fertilizer bin through a medicine mixing pipeline and a medicine outlet pipeline. The water tank is opened and closed according to ion concentration detection, and the liquid fertilizer is mixed to increase the solvent content and adjust the ion concentration. The electrolysis device generates hydrogen and ions. The ions are dissolved in the fertilizer bin solution, and hydrogen and carbon dioxide float into the gas fertilizer bin. The carbon dioxide acts on the plant leaves through a separate pipeline, and the hydrogen and oxygen gas are mixed with the liquid fertilizer in the medicine mixing pipeline through another pipeline to form gas-liquid fertilizer drip irrigation for the plant roots. The application can meet the needs of plants for different elements or ions and realize precise fertilization.
