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 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.
