The invention provides a compound spray for treating a cardiovascular and cerebrovascular diseases, which is prepared by mixing pharmaceutic adjuvant to ethanol solution of raw material drug to prepare solution; the raw material drug includes 25 to 68 percent of red sage root extract, and 32 to 75 percent of panax notoginseng saponins in weight percentage; the medical assistant includes a solubilizer and a propellant, wherein the solubilizer is 1 to 10 percent the total weight of the solution; and the solubilizer is one or more of polysorbate, fatty acid sorbitan, polyoxyethylene aliphatic ester, polyoxyethylene fatty alcohol ether, and polyoxyethylene-polyoxypropylene copolymer. The compound spray uses the panax notoginseng saponins and the red sage root extract as the main drugs for quickly treating the cardiovascular and cerebrovascular diseases; the compound can exert coordination effect, particularly during the acute exacerbation period of the cardiovascular and cerebrovascular diseases, the compound spray works fast, so as to reach the expected treatment effect and have obvious treatment effect.

The invention discloses a special-shaped gear with an internal shaping layer and its processing technology, belonging to the technical field of gear processing. A special-shaped gear with an internal shaping layer includes a special-shaped gear body, and a self-fitting gear is provided inside the special-shaped gear body. Tooth surface tube, self-fitting tooth surface tube includes a self-fitting tube and a reinforcing fixed tube, the outer end of the self-fitting tube is wrapped with a self-lubricating ring and a selectively permeable film layer, a selectively permeable film layer and a self-lubricating ring There are many small oil pockets between them. After the last process of traditional gear processing, a self-fitting tooth surface operation is added. A self-fitting tooth surface tube is added on the inner side of the gear, and the self-fitting tooth surface tube is used to fit tightly Protect the gear teeth on the surface of the gear teeth, reduce the wear of the gear teeth during transportation and movement, and ensure its precision. In addition, through the setting of the self-lubricating ring on the surface of the self-fitting tooth surface tube, the gears can be adjusted when using the gears. The surface of the teeth produces comprehensive lubrication, which eliminates the separate oiling steps in traditional installation operations.

The invention belongs to ornamental horticultural seedling raising technology, in particular to a method for quickly releasing dormancy of sweet-scented osmanthus seeds. The steps include: from late April to late May, when the sweet-scented osmanthus fruit turns blue-purple, harvest, remove the pulp, clean and dry the seeds; pick out a large, plump, pest-free seed, and use permanganate Soak in potassium solution for 30 minutes, pour off the solution and suffocate for 10 minutes, wash the seeds and dry them; rub the two ends and four sides of the osmanthus seeds with sandpaper; soak the mechanically treated seeds with a mixed solution of gibberellin and lanthanum nitrate; Mix the soaked seeds with wet sand, put them into a container, cover the surface with plastic wrap, punch holes, and carry out low-temperature stratification. The operation method of the invention is simple and easy, has low cost and high germination rate, and is suitable for both test and production needs.
