The invention provides a method for rapidly reproducing high quality germchit with dendrobium officinale, which is characterized in that: (1) folded sprouts of the dendrobium officinale are taken andsterilized, and stem apexes are inoculated to a solid culture medium to establish a non-bacterial system; (2) the stem sections or small basal tissue blocks of the young seedlings of the non-bacterialsystem are cut for inducing protocorm based on suitable hormone combination and a culture medium; (3) the protocorm is cultured alternatively on liquid and solid subculture mediums for rapid multiplication to form protocorm masses; (4) the protocorm masses are cut apart and transferred on a solid planting medium for disuniting plants into small seedlings; (5) the small seedlings are transferred on a solid strong seedling culture medium for strengthening the seedlings and taking roots to culture complete plants; (6) the non-bacterial strong seedlings are fixedly planted in suitable seedling adapting substrate to obtain the high quality germchit. The method can be used in large scale industrialization and the explants have the advantages of high soil removal efficiency, high multiplicationrate, low variability, strong germchit, good quality, high survival rate after being transplanted, strong growth potential, etc.

The invention discloses a combined multifunctional flowerpot. An upper cover (1) is fixedly arranged on an outer barrel (7); a preserved hole (13) is formed in the middle of the upper cover; the outer edge of the upper cover and the preserved hole (13) are both of geometrical shapes; an inner barrel (3) is arranged in the preserved hole (13) and is placed on a lug boss (73) on the bottom of the outer barrel; a water-sucking component is arranged at the bottom of the inner barrel; a vent (33) is formed in the bottom of the inner barrel; a water filling nozzle cover (4) covers a water filling nozzle (12); a flower tray (8) is arranged on a flower tray placing table (34) on the side wall of the inner barrel; a water-drawing component (A) is arranged on the flower tray; a sealing component (C) seals the water-sucking component and the vent (33). The combined multifunctional flowerpot is simple in structure, and a user can plant a big plant or a small plant at pleasure because of the arrangement of the flower tray; the flower tray is placed to place the small plant, water in the barrel slowly flows to soil because of a water-sucking device, and flower and grass can also be guaranteed to well grow without frequently watering; the combined multifunctional flowerpot is easy to assemble and transport and convenient to store; each part of the combined multifunctional flowerpot can be replaced independently, so that the cost is reduced.

End parts of liquid storage grids of a safety-type immunohistochemical wet box are matched with splash proof covers; a bottom plate and four clapboards encircle to form each splash proof cover, the upper end of the splash proof cover is provided with an opening, the internal of the splash proof cover is hollow, the end surface of the bottom plate end is square, the area of the bottom plate is less than that of the cross-sectional area of the liquid storage grid, lower end parts of the four clapboards are in one-to-one correspondence connection with four sides of the bottom plate, upper end parts of the four clapboards encircle to form a square end port equal to the cross-sectional area of the liquid storage grid, each clapboard is provided with run-through security holes, the end port position of a security hole located on the outer wall of the clapboard is higher than the end port position of a security hole located on the inner wall of the clapboard, the periphery of the bottom plate is provided with a liquid storage grove, and a liquid return hole is arranged between the end part of the liquid storage grove and the side wall of the bottom plate. When the liquid level of moisturizing water sloshes due to the effect of external factors during use of the safety-type immunohistochemical wet box, splashed and scattered droplets does not have enough speed to ''splash'' to the upper side of the bottom plate due to presence of the security holes, and to-be-moisturized object pollution cause by splashing of the moisturizing water can be avoided.

The invention discloses a single part used for a fuel cell. The single part is a multi-phase and multi-component composite film, wherein the composite film comprises five components of polyvinyl alcohol, anion exchange resin, perfluorosulfonate resin, a transitional metal oxide and a transitional metal hydroxide, wherein the polyvinyl alcohol and perfluorosulfonate resin are mixed uniformly to form a film substrate; the anion exchange resin is embedded in the film substrate in a granular way; and the transitional metal oxide and the transitional metal hydroxide are uniformly dispersed in the film substrate in a nanoparticle form. The invention also discloses a preparation method for the single part; a gel film coating method is adopted; the preparation method is simple and easy to control, and suitable for large-scale application; the single part provided by the invention is assembled with a flow field, a clamping plate, a pipeline and other auxiliary parts to form the fuel cell; the fuel cell can realize power generation to the outside by pumping fuel and oxygen; and therefore, the single part can replace a positive electrode-electrolyte film-negative electrode sandwich structure of the conventional fuel cell, so that the battery and the production assembling process can be greatly simplified.

The invention discloses a method for drying ceramic blank. The method comprises the steps of leading a thermal medium to a drying kiln, mixing the thermal medium with steam, and mixing the steam with the thermal medium before the thermal medium enters the drying kiln. After optimization, humidity of the thermal medium is adjustable; and the humidity of the thermal medium is decreased progressively along with the drying degree of the ceramic blank. The invention further discloses the energy-saving rapid drying kiln used in the method.

The invention discloses an amphoteric ion exchange membrane for a fuel cell. The amphoteric ion exchange membrane employs polyvinyl alcohol and perfluorinated sulfonic acid resin as a membrane substrate, wherein negative ion exchange resin is intercalated into the membrane substrate in a particle mode, and nickel oxide hydroxide is loaded in the negative ion exchange resin particles. The invention also discloses a preparation method of the amphoteric ion exchange membrane. The preparation method comprises the steps of loading the nickel oxide hydroxide in the negative ion exchange resin particles, preparing gel of the membrane substrate comprising the polyvinyl alcohol and the perfluorinated sulfonic acid resin, forming the gel of the negative ion exchange resin intercalated into the membrane substrate in the particle mode, and further forming the amphoteric ion exchange membrane, wherein the additive proportion of the substrate membrane and the negative ion exchange resin is controlled by calculating positive ion conductivity s<positive> of the substrate membrane and negative ion conductivity s<negative> of the negative ion exchange resin particles during the preparation process. With the amphoteric ion exchange membrane prepared according to the method, the problems of low ion conductivity and fuel permeation of the negative ion exchange membrane are solved, and meanwhile, the problem that a proton exchange membrane shall employ precious metal as a catalyst is also solved.
