The invention relates to underwater robot technology and aims to provide a control method for a four-rotor spherical underwater robot. During the operation of the underwater robot, the motor drive module is connected to the battery, the control board and the motor of the thruster through wires to drive the propeller. heading, and transmit the signal to realize PID control to the motor drive module. Based on the control method of the underwater robot described in the present invention, the corresponding control algorithm can be used to realize the thrust distribution of the propeller, and then realize the motion of the underwater robot with no less than four degrees of freedom, including hovering at a fixed depth, going straight, rotating, and moving sideways ability.

The invention provides a Chinese medicinal composition for promoting mature of internal arteriovenous fistula and reducing complications, an application and a using method thereof. The Chinese medicinal composition comprises a component A and a component B, wherein the component A is composed of rheum officinale, mirabilite, borneol and paris polyphylla, and the component B is composed of ligusticum wallichii, Chinese angelica, borneol and leech. The Chinese medicinal composition is prepared by adopting the following steps: baking and crushing the component A, and screening through a 100-mesh screen; gradually adding water, and stirring to obtain a paste medicament; immersing the component B with water, decocting for three times, and filtering the filtrates of three times and concentrating to obtain an ointment medicament, wherein an interval is not needed in each time of decoction. The paste medicament is applied to the hand back each time before sleep, and is washed after wakeup in the morning three days before an operation; 2ml of the ointment medicament is applied to the affected part one time a day after suture is taken out after 7-10 days of the operation; 14 days is taken as a course of treatment, and 1-2 courses are used. The Chinese medicinal composition is convenient to obtain materials and easy to manufacture, is convenient to use, economical and practical, has the advantages of low cost, no toxicity or hazard, remarkable use effect and the like, and is mainly used for a patient who is subjected to uremia arteriovenous fistula plasty. The Chinese medicinal composition avoids the adverse response caused by internal administration, and plays an active and effective effect in the process of treating chronic renal failure.

The invention discloses a fingerprint developing agent based on a fluorescent colloid particle solution, a preparation method and an application. The PPV precursor solution was prepared by the Wessling sulfonium salt precursor method. After adding an anionic surfactant, branched polyethyleneimine was used as a catalyst to obtain a solution containing branched polyethylene by self-assembly of the polymer chain during the elimination process. imine in PPV colloidal particle solution. Use the soaking method to visualize sweat latent fingerprints and blood latent fingerprints on different objects. Clear and bright fingerprint lines can be observed under ultraviolet light, which is suitable for fingerprint identification. The PPV colloidal particle imaging agent solution provided by the invention has simple preparation process and convenient operation, can overcome the interference of complex background patterns, and visualize sweat latent fingerprints and latent blood fingerprints on different objects; and the imaging agent is an aqueous dispersion, which is environmentally friendly , and can be used multiple times, saving cost, and suitable for industrial production and routine fingerprint display work.

A traditional Chinese medicine composition for promoting post-cesarean incision healing of elderly parturient women and reducing complications comprises the following medicinal materials: 10-15 parts of magnet, 3-5 parts of panax notoginseng, 6-10 parts of hairyvein agrimonia herb, 1-3 parts of sangusis draconis, 5-8 parts of olibanum, 5-8 parts of myrrh, 8-12 parts of callicarpa nudiflora, 3-5 parts of lamiophlomis rotata, 8-12 parts of euphorbiae maculate, 8-12 parts of leonurus, 3-5 parts of aloe, 3-5 parts of carbonized hair, and 1-3 parts of astragalus mongholicus or 8-12 parts of astragalus mongholicus. The composition is convenient in material drawing and easy to prepare; two traditional Chinese medicine formulae are used jointly; the composition has the advantages of convenience in use, low cost, economy, no toxicity or hazard, definite use effect and the like; for the characteristics of protracted post-cesarean incision, postoperative pain and the like of some elderly parturient women, the pure traditional Chinese medicine preparation is adopted; and the composition has effects of stopping bleeding, promoting blood circulation, alleviating the pain and consolidating the constitution, can obviously relieve the pain and the complications of elderly parturient woman patients and accelerates the incision healing.

The invention relates to the technical field of underwater robots and aims to provide an underwater unmanned aerial vehicle with fixed wings. Propellers are mounted on a driving shaft of a brushless motor, and the brushless motor is fixed at the front end of a fuselage; lateral wings and wing flaps are respectively composed of components which are symmetrically arranged at two sides of the fuselage, and the wing flaps are positioned at the rear sides of the lateral wings, wherein the lateral wings include a left side wing and a right side wing which are respectively fixed on the side surfacesof the fuselage, the cross section of each lateral wing is in a drop shape, and the tail end of each lateral wing faces towards the direction of the tail of the fuselage; the wing flaps include a leftwing flap and a right wing flap which are connected with a left steering engine and a right steering engine respectively through a left steering engine arm and a right steering engine arm, and the steering engines are fixed on the side surfaces of the fuselage; tail wings are connected with a rear steering engine through a rear steering engine arm, and the rear steering engine is fixed at the tail of the fuselage; and the connecting line of the propellers, the brushless motor and the tail wings is parallel to or coincident with the axis of the fuselage. The underwater unmanned aerial vehicleprovided by the invention is small in size, light in weight, simple and convenient in operation and easy to control, has no need of other auxiliary devices, has definite purposes and use values, and is convenient to popularize, and the price is low.

The invention provides an externally-used traditional Chinese medicines formula for preventing chronic subdural haematoma postoperative complications and a preparation method. The externally-used traditional Chinese medicines formula consists of hematoxylon 3000 g, rhizoma bletillae 2000 g, large-leaved gentian 1000 g, radix aconiti preparata 1500 g, radix clematidis 1500 g, flowers carthami 1500 g, schizonepeta 1000 g, radices sileris 1000 g, mirabilite 200 g, borneol 50 g and muskone 20 g. The preparation method comprises the steps of decocting the previous eight medicine materials for two times, mixing decocted fluids to be concentrated, adding the mirabilite to perform sterile filling so as to obtain a decocted medicine fluid; solving the borneol and the muskone in 75% of ethanol solution to be mixed evenly so as to obtain the ethyl alcohol solution.
