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 relates to an in-situ electrochemical cell for combining an electrochemical quartz crystal microbalance and a fluorescence spectrum. The in-situ electrochemical cell comprises a polytetrafluoroethylene solution cell, a horizontal cell loaded at a horizontal section and an observation channel at a cross section, wherein the horizontal cell comprises a shockproof thickened base, a first detachable cover and a second detachable cover; the observation channel is loaded at the upper part of the electrochemical cell and comprises an incident light path, a reflected light path and a pyramid quartz window; the first detachable cover and the second detachable cover are provided with three electrode fixing blocks for respectively placing a working electrode, a reference electrode and acounter electrode so as to form a three-electrode system; a light through hole is formed in the second detachable cover so as to enable the working electrode to receive fluorescence spectrum lighting; and a light path conversion device is arranged in the cross section to enable signal light reflected by the working electrode to reach a signal receiver in the horizontal direction. The problems that a conventional in-situ electrochemical cell is incompatible with a fluorescence test system, and due to insufficient solution gravity and sealing performance, the electrochemical cell leaks liquid or is not suitable for testing a water-oxygen sensitive system are solved.

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 the technical field of electronic equipment, and discloses a folding display device, a mobile terminal and a display method. The folding display device includes a casing and a flexible screen. The flexible screen is used to display objects and includes a first part, a second part and a bendable screen. The third part; the housing includes the front of the housing, the first part is slidably supported on the front of the housing; the housing also includes a receiving groove extending parallel to the front of the housing, when the third part is bent, the second part can slide into the holding tank. A mobile terminal includes the above-mentioned folding display device. The display method includes detecting the state of the flexible screen; according to the state, respectively controlling the display of the first part, the second part and the third part. The invention can fold the flexible screen and store it in the accommodation groove to avoid contact with the outside world; by detecting the state of the flexible screen and controlling the display area of ​​the flexible screen, the display state of the flexible screen can be enriched.

The invention discloses a cold storage, comprising: a storage body, which is provided with a partition board inside, which divides the storage body into a refrigerator room and a quick-freezing room, a first opening is arranged on the side wall of the storage body, and a first electric door is arranged at the first opening The buffer chamber has a shared side wall, the first opening is located within the range of the shared side wall, the side wall adjacent to the buffer chamber and the shared side wall is provided with a second opening, and the second opening is provided with a second electric door, The top surface of the buffer chamber is provided with a third opening; a plurality of air outlet pipes are arranged on the top of the buffer chamber in parallel at intervals, and the plurality of air outlet pipes are connected to the air inlet pipe arranged outside the buffer chamber. A first blower fan and a dehumidification structure are arranged at intervals; an air induction cover has a large opening end and a small opening end, the large opening end cover is arranged at the third opening, and the small opening end is provided with a second blower fan. The invention reduces the heat exchange between the cold storage and the outside world and reduces the entry of external humid air into the cold storage by adding a buffer room, an air outlet pipe and an air induction cover.

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.
