The invention discloses a preparation method of an in-situ synthesized carbon nano-tube modified SiCN ceramic matrix composite material so as to solve the technical problem that CNTs (carbon nano-tubes) and an SiCN ceramic matrix cannot be generated synchronously in existing CVD / CVI (chemical vapor deposition / chemical vapor infiltration) methods. According to the technical scheme involved in the invention, a CVD / CVI process is adopted, respectively, SiCl4, SiHCl3 or CH3SiCl3 is taken as a silicon source, CH4 or C3H6 is taken as a carbon source, NH3 is taken as a nitrogen source, H2 is employed as a bubbling carrier gas and reducing gas, and Ar is adopted as a diluent gas. By adding Fe(NO3)3.9H2O, Co(NO3)2.6H2O or Ni(NO3)2.6H2O and other metal salt catalysts, the Fe, Co, Ni nanoparticles produced by metal salt reduction can be utilized to capture a large number of free carbon atoms existing in the Si-C-N system, so that the purpose of synchronous synthesis of CNTs and the SiCN ceramic matrix on a base material can further be achieved.

The invention belongs to an organic metal oxide-TiO2 photocatalyst preparing process, especially relating a synthesizing method of low temperature-crystallizing nanometer TiO powder and sol with high catalytic activity. And it obtains n-titanic acid deposit by making alkali neutralization and dilution hydrolyzation or heating hydrolyzation on titanic solution, and implements synthesizing related system nano crystal materials with normal-pressure and low-temperature liquid phases by such a processing process of re-dispersing the deposit by oxydol. And it largely reduces the cost of raw materials and avoids using titanium tetrachloride with strong corrosivity, reducing equipment requirements.

The invention discloses a method for preparing a refined celery extract, relates to a method for preparing an extract from chemical ingredients in a plant and solves the problems of low ingredient purity and poor application effect of a flavonoid in the conventional celery extract. The method for preparing the refined celery extract comprises the following steps of: 1, preparing a crude celery extract; 2, adsorbing the prepared celery extract by using AB-8 macro-porous resin; and 3, drying the celery extract in vacuum so as to obtain the refined celery extract. In the refined celery extract, a flavonoid ingredient has high purity and good application effect. The method is widely applied to the extraction and separation of the chemical ingredients in the plant and is an effective method for separating and purifying plant ingredients.

The invention relates to a method for producing flavor fermented blank bean. The flavor fermented blank bean comprises the following raw materials in parts by weight: 50-60 parts of original-flavor fermented blank bean, 1-5 parts of white spirits, 5-15 parts of edible salt, 1-5 pars of dried momordica grosvenori, 1-5 parts of glycyrrhiza uralensis, 0.25-1.25 parts of white sugar, 0.05-0.25 part of monosodium glutamate, 1-5 parts of radix puerariae, 1-5 parts of honeysuckle, 5-15 parts of red peppers, 5-15 parts of a ginger juice, and 10-15 parts of mashed garlic. With the raw materials and the improved fermented blank bean process, the prepared fermented blank bean has good taste and strong and pervasive bean fragrant, is suitable for different groups of people, and also can clear heat and remove toxicity.
