The invention discloses a process for producing bead ferronickel by a rotary hearth furnace through coal-based reduction of red soil nickel oxide ores, which is capable of reducing the production cost and belongs to the technical field of production of iron alloys. The process comprises the following steps of: a, after finely crushing, dosing, mixing and pelletizing raw red soil nickel oxide ores, reducing coal and a flux, drying to obtain dry balls; b, reducing the dry balls into the rotary hearth furnace, and carrying out water quenching, cooling, crushing and magnetic separation on the discharged high-temperature clinker so as to obtain a bead ferronickel alloy and slag. According to the invention, the rotary hearth furnace is taken as a reducing device, non-coking coal with cheap price and wide resource distribution is directly taken as a reducing agent, and coal gas is taken as main energy, so that the production cost is low, the process is applied to a construction plant of a mine region with power resource scarcity, the restriction condition of higher transportation cost of raw materials of the conventional factory is overcome, the process is simple and easy to operate and put into large-scale production application, and the obtained bead ferronickel has high nickel grade and high metal recovery rate, and is a high-quality raw material for producing stainless steel.

The invention discloses a pharmaceutical composition for preventing and treating osteoporosis and a preparation method thereof. The pharmaceutical composition is prepared from epimedium extract and glossy privet fruit extract. The pharmaceutical composition has the advantages that (1) the traditional Chinese medicinal extract composition selects epimedium and glossy privet fruit extract for mild tonifying kidney and balancing yin and yang as study objects regarding the characteristics of OP (osteoporosis) pathogenesis, namely deficiency in kidney-essence and deficiency of yin and yang, so that basis is provided to development of a novel anti-osteoporosis medicine of effective components of epimedium and glossy privet fruit capable of mild tonifying yin and yang; (2) the bulk drug for the traditional Chinese medicinal composition preparation is wide in resource distribution and low in toxic and side effect, and can be taken for a long time; (3) the traditional Chinese medicinal composition is concise in prescription, definite in effective component, exact in curative effect and controllable in quality, does not need the traditional Chinese medicine decocting process, and is convenient to take.

The invention relates to the technical field of new energy and discloses a solar panel with convenience in angle adjustment. The solar panel comprises a base, wherein a rectangular inner chamber is formed in the base, two positioning grooves are formed in the inner bottom wall of the rectangular inner chamber, first bearings are fixedly mounted in the two positioning grooves, a first rotating rodis fixedly mounted in the first bearing on the left side, and a first gear is fixedly mounted on the outer side of the first rotating rod and inside the rectangular inner chamber. According to the solar panel with convenience in angle adjustment, the first gear is driven to rotate by a drive motor and drives a second gear to rotate, so that a mounting plate can rotate for 360 degrees, demands of the solar panel for light in different directions are met effectively, and work efficiency of the solar panel is increased greatly; meanwhile, compared with traditional manual adjustment, the solar panel has the advantages that labor intensity can be reduced effectively, and angle precision is improved effectively.

The invention relates to the field of natural medicines, and particularly discloses an active component with a diuretic effect extracted from akebia trifoliata, a preparation method and an applicationof the component. The active component is extracted from akebia trifoliata, and the method includes the following steps: (1) preparing an extract; (2) extracting a solvent; (3) washing and concentrating the extract; and (4) purifying by silica gel column chromatography. The active component obtained by the above method steps contains 40-90% of total saponin by mass; the total saponin comprises four saponins of Saponin PH, Akemisaponins E, Saponin PJ1 and Scheffoleoside A, and the four saponins account for more than 60% of the total saponin in the active component by mass; and the active component extracted from akebia trifoliata contains the four saponins which have mutual synergistic effects, do not need component separation and purification, and are directly used for preparing diureticdrugs.
