The present invention provides an optical connection structure and optical connection method for enabling a connection characterized by a simple structure, ability to retain optical fibers in an adhered state, easy installation and detachment / attachment, and excellent optical stability. The optical connection structure proposed by the present invention has a solid viscous connection member having refractive-index matching property disposed in a single layer state between the end faces of mutually opposing optical transmission media or between the end face of an optical transmission medium and an optical component that are mutually opposing. The solid viscous connection member should desirably be made of silicone resin or acrylic resin.

The invention provides a method for preventing and treating tobacco bacterial wilt, and belongs to the technical field of protecting of plants. The method for preventing and treating the tobacco bacterial wilt includes the first step, when tobacco seedlings are transplanted, Likujing (a kind of farm chemical) and water are mixed according to the weight ratio of 1:800-1200 to prepare Likujing pesticide liquid in a diluting mode, root-irrigation is performed on the tobacco seedlings with the Likujing pesticide liquid, and 40-60ml pesticide liquid is used for the root-irrigation of each tobacco seedling; the second step, in the early period of morbidity of tobacco plants, Baikang (a kind of farm chemical) and water are mixed according to the weight ratio of 1:500-1000 to prepare Baikang pesticide liquid, the Baikang pesticide liquid is sprayed on the rootstock portions of the tobacco pants in the morbidity, and 75-150ml pesticide liquid is sprayed on each tobacco plant. The method for preventing and treating the tobacco bacterial wilt has the advantages of being scientific, practical, easy and convenient to operate, easy to master, free of affecting production value and yield of tobacco leaves, free of negative affects on the environment and the like, and has good preventing and treating effect on the tobacco bacterial wilt, the occurrence rate of the tobacco bacterial wilt is obviously reduced after the method is adopted, and therefore the quality of tobacco can be improved, and the method is suitable for being popularized in a larger area.

A torque-limiting coupling may be used to provide a torsion drive between an engine or motor and a driven accessory. If an accessory should experience a catastrophic failure a torsion limit is exceeded and a spline breaks away from the coupling. This guarantees that the internal engine gearing used to drive the accessory is not compromised and interfering with essential moving parts inside the engine. Further, a misalignment compensation limits the side load and wear that occurs when coupling two precision shafts with little clearance on the bearings. With a misalignment coupling, the mount can be slightly out of parallel with no negative effects.

A method of making an inverted bottom-emitting OLED device, comprising: providing a substrate; providing one or more first electrodes driven by n-type transistors on the substrate; providing an electron-transporting layer over the substrate and first electrode(s), wherein the electron-transporting layer comprises an n-type inorganic semiconductive material with a resistivity in the range of 1 to 105 ohm-cm and a bandgap greater than 2.5 eV; providing an organic light-emitting layer over the electron-transporting layer; providing a hole-transporting layer over the organic emitting layer; and providing a second electrode over the hole-transporting layer.

The invention relates to a recombinant maple essence based on fragrance threshold, characterized in that the recombinant maple essence is composed of fragrance components, sugars and solvents, wherein the recombinant maple essence is calculated as 100%, and each component in the fragrance components Including methylcyclopentenolone, 2-acetylfuran, 5-hydroxymethylfurfural, furfural, acetylpyrrole, 2.6-dimethylpyrazine, β-damascenone, linalool, trigonelactone, α-angelica lactone, benzyl benzoate, vanillin, nonanoic acid, citric acid, fumaric acid; the weight ratio of each component in the sugar is: sucrose 0-1%, fructose 2-2.6%, Glucose 10-16%, maltose 20-32%; the balance is solvent. The recombinant maple flavor is applied to cigarettes, which can significantly increase the aroma and smoke concentration of cigarettes, enhance the aroma quality, and improve comfort, and has no negative effects such as burnt bitterness, sweetness and greasy feeling.

The invention provides a cleaning agent that can effectively remove coking and carbon deposits on the surface of needles in the transmission system of wood-based panel hot press equipment. Its components include 85%-95% of low viscosity base oil and 0.1%- nonionic surfactant. 0.5%, main cleaning agent 5%-10%, dispersant 0.5%-2%, detergent 0.5%-2%, wherein the low-viscosity base oil has a viscosity of less than 100mm at 40°C 2 / s; the main cleaning agent is isopropanolamide and ethylenediamine oleate; the nonionic surfactant is one or both of oleic acid diethanolamide and lauric acid diethanolamide , the non-ionic surfactant can enhance the solubility of the main cleaning agent in the base oil; the dispersant is polyisobutylene succinimide; the detergent is calcium sulfonate with high alkalinity. The cleaning agent of the present invention can achieve the cleaning effect of effectively removing coking and coking deposits of wood-based panel equipment at 40°C-80°C.

The invention discloses a wood modification liquid and a method for treating wood by using the same. The wood modification liquid consists of 0.5-5% activator, 5-50% low-molecular sugar, 0-3% It is made of catalyst, 0-0.5% stabilizer, 0.5-5% additive and water. The method of the wood modification treatment is: inject the wood modification liquid into the wood material under vacuum and pressurized conditions, and make the active functional groups in the modifier and the hydroxyl groups of the wood cell wall undergo a graft reaction under high-temperature drying conditions, thereby Fixed in the wood cell wall. The activator described in the present invention is a green environmental protection agent. In the process of activating the low molecular sugar, the activator can decompose itself into water and oxygen, or can be separated and recycled, and will not have negative effects on the wood modifier and the environment. It effectively solves the problem of release of small molecule volatiles such as formaldehyde, phenol, and acetic acid in the existing wood modification technology.

The invention provides a method for preparing a reconstituted tobacco leaf coating solution. The method is to add tap water to the mixture of tobacco stalks, tobacco powder and secondary tobacco leaves and mix them evenly, then dynamically countercurrent extract to obtain insoluble slurry and extract; filter the extract to obtain filtrate A and retentate A; use potassium dihydrogen phosphate Adjust the pH value of the retentate solution A, and add glycosidase to the retentate solution A after adjusting the pH value for enzymolysis, then add chitosan aqueous solution to the enzymolysis solution, stir and mix evenly, and take the supernatant after standing still. Filter to obtain filtrate B; combine filtrate A and filtrate B, concentrate under reduced pressure to obtain concentrate A, add sodium glutamate for Maillard reaction, add liquid fructose, stir evenly, and centrifuge to collect the filtrate. Coating solution for reconstituted tobacco leaves. The method in the present invention is energy-saving and environment-friendly, and the prepared reconstituted tobacco leaf coating liquid has a strong aroma, can enhance aroma quality, increase the fluttering feeling of smoke, reduce throat irritation, and improve oral aftertaste.
