The invention provides a method for preparing vanadyl sulfate. According to the method, a technical process that ion exchange resin is adopted to selectively adsorb vanadium and reduce and desorb vanadium so as to directly prepare vanadyl sulfate is adopted, so that a middle process in which powder high-purity vanadium pentoxide is prepared is canceled. In addition, as the decontamination process is evolved into direct selective pure vanadium extraction, contamination and the labor and material consumption in the decontamination process are avoided, the operation procedure is greatly simplified. Compared with a conventional vanadyl sulfate preparation process, the method has the advantages of short procedure, high vanadium yield, low cost, no waste discharge and the like.

The invention discloses a degradation-image subjective quality material library construction method based on transmission. The method comprises the following steps of S1, defining and constructing material library correlation concept; S2, according to a definition, selecting a raw material; S3, acquiring a degradation material based on transmission; S4, grouping degradation images; S5, evaluating an environment and evaluating condition setting; S6, evaluating subjective quality; S7, carrying out evaluated data processing, which includes evaluated image and volunteer screening; and S8, determining the subjective quality corresponding to each image. The method is suitable for image quality evaluation and restoration under a communication background; a simulation mode is used to acquire the degradation images so that consumption of manpower and material resources during real transmission can be avoided; and simultaneously two kinds of schemes with different robustness are taken as a source compression mode so as to carry out channel transmission error code simulation, and an error code rate is arranged according to data acquired from a real communication experiment. Besides, a maximum probability principle is used to determine a final quality grade of each image so that an influence of an evaluation sample with a large deviation on a result is avoided.

The invention discloses a support cleaning device for preventing collapse of a blasthole in advance tunnel prediction and a use method thereof. The support cleaning device comprises a support device portion for supporting the pressure generated by gravel soil above a blasthole, a rail connection portion and a rock soil cleaning portion. The rock soil cleaning portion arranged between the support device portion and the rail connection portion can slide back and forth between the support device portion and the rail connection portion. The gravel soil in the blasthole is removed by pulling and slipping the rock soil cleaning portion. Therefore, a phenomenon that the depth of the explosive is too shallow due to the collapse of the blasthole when the explosive is placed is avoided; and thus theexperiment is down successfully and conveniently.
