The invention discloses a flip-chip type semiconductor luminescent device structure and a manufacture method thereof. The flip-chip type semiconductor luminescent device structure comprises a supporting base plate, a luminous epitaxial layer and a light-transmitting growth substrate, wherein the luminous epitaxial layer is located on the supporting base plate and is sequentially formed by a p-shaped semiconductor layer, a luminous active layer, an n-shaped semiconductor layer and a buffering layer, and the light-transmitting growth substrate is located on the luminous epitaxial layer. The flip-chip type semiconductor luminescent device structure is characterized in that a regular graphical air interlayer is located between the light-transmitting growth substrate and the luminous epitaxial layer and has optical matching thickness. By means of the graphical air interlayer located between the light-transmitting growth substrate and the luminous epitaxial layer and having the optical matching thickness, the effects of light transmitting and radiation can be achieved.

The invention relates to an early-bearing and high-yield Camellia oleifera cultivation method and belongs to the technical field of economic forest planting. The method comprises steps as follows: (1) establishment of forest land: selection of nursery stocks, land preparation, application of base fertilizer and planting; (2) management of a young forest: application of fertilizer, tending and weeding as well as tree shape pruning; (3) disease and pest control: disease control and pest control; (4) transplantation. With the adoption of the Camellia oleifera cultivation method, 60 kg of camellia oil is averagely produced per mu in the fifth year after planting, compared with the traditional yield of 10-15 kg of the camellia oil per mu, the yield is increased by 3-5 times, and the method is an important early high-yield and high-efficiency technology for Camellia oleifera. A Camellia oleifera high-yield forest has an area of 23 mu, 61.25 kg of the camellia oil is averagely produced per mu in 2015, and 1408.75 kg of the camellia oil is produced totally.

Provided is a member for displaying a projected image, including: a first base material; a second base material; and an optical member, in which at least one optical member is disposed on a surface of the first base material or the second base material, the optical member includes a plurality of cholesteric liquid crystal dots, the cholesteric liquid crystal dot is formed of a liquid crystal material having a cholesteric structure, the cholesteric structure imparts a striped pattern formed of bright portions and dark portions in a cross-sectional image of the cholesteric liquid crystal dot taken by a scanning electron microscope in a direction perpendicular to a substrate, the dot includes a portion where the height thereof successively increases to the maximum height thereof from an end portion toward the center thereof, an angle between a normal line with respect to a line formed by the first dark portion from the surface of the dot on a side opposite to the substrate and a line representing the surface of the is in a range of 70° to 90° in this portion of the cross-sectional image, and a reflection center wavelength of the dot is in a range of 400 to 1000 nm.

The invention discloses a preparing method for a hydroxypropyl methyl cellulose crosslinked membrane. According to the method, collected corn stigmas are subjected to air drying, clipping, grinding and screening, powdery raw materials are obtained, the screened corn stigmas are scattered in a TBAA/DMAc ionic solution, cellulose nanocrystalline is dissociated and subjected to the esterification reaction with dripped acetic anhydride, and cellulose acetate nanocrystalline is prepared; the above modified cellulose nanocrystalline and the hydroxypropyl methyl cellulose DMAc dissolving solution are mixed, glutaric anhydride is added, after forming in a die and low-temperature drying film forming, the heating esterification cross-linking reaction is conducted, a product is cleaned, and after cold drying, the corn stigma modified cellulose blended film is obtained. A mulching film prepared through the method is a transparent film, high tensile performance and pull-up performance are achieved, and good waterproof performance and oxygen isolation performance are achieved.

The invention belongs to the technical field of glutamic acid fermentation, and discloses a glutamic acid fermentation method and a monosodium glutamate production method. Corn steep liquor is concentrated and is subjected to enzymolysis at proper temperature, pH value and time; and activated carbon is added for adsorption decoloration, and a decolorizing liquid is used for glutamic acid fermentation to provide a nitrogen source and inorganic phosphorus so as to replace the nitrogen source and phosphate in an original culture medium. The baume degree of the concentrated corn steep liquor is 20-25. The hydrolase comprises phytic acid complex enzyme and protease. The corn steep liquor is subjected to enzymolysis, so that the content of available free phosphorus and amino acid is increased, inorganic phosphorus and part of protein hydrolysate in glutamic acid fermentation ingredients are completely replaced, the resource utilization rate is increased, the production cost is reduced, dipotassium phosphate is saved by 9.09 kg/ton in unit glutamic acid, and 1.5 kg/ton defoaming agent is saved. Resin decoloration replaces decoloration of granular activated carbon in the original process,the light transmittance of a neutralization solution can be improved to 93%-98%, and 75% of washing sewage can be reduced compared with the original process.
