The lens is made of the raw materials, parts by weight, consisting of the quartz sand of 52-58 parts, the alum of 4-8 parts, the sodium carbonate of 10-13 parts, the nanometer silicon dioxide of 4-6 parts, the modified graphene of 8-12 parts, the lithium hydrate of 4-6 parts, the hafnium boride of 7.5-8 parts, the potassium chloride of 8-10 parts, the vanadium pentoxide 5-8 parts, the iron carbide of 5-8 parts, the barium silicide of 4-6 parts, the tungsten silicide of 1-2 parts, the cobalt dioxide of 4-5.5 parts and the vitrification fiber of 2.5-3 parts. The lens is good in the diffraction to the ray of light and very low in optical return, is very suitable for the shooting usage in the highlight, and is low in the lens image drifting.

The invention discloses a Dendrobium officinale culture solution and belongs to the technical field of agricultural planting. The culture solution comprises the following ingredients: potassium nitrate, ammonium nitrate, magnesium sulfate, manganese sulfate, zinc sulfate, monopotassium phosphate, copper sulfate, potassium iodide, cobalt dichloride, boric acid, sodium molybdate, vitamin VB1, vitamin VB6, vitamin VB5, glycine, ferrous sulfate, disodium ethylenediamine tetraacetic acid, calcium chloride, naphthylacetic acid, mashed banana, mashed potato, white sugar, inositol, and powdered agar. The dendrobium officinale culture solution is reasonable in compatibility, can provide comprehensive nutrition for a Dendrobium officinale stem, fast promote the stem to grow out of a root, increase the polysaccharide content and the amino acid content in the Dendrobium officinale, shorten the time for culturing the Dendrobium officinale stem to a complete plant to about 25 days, and significantly improve the transplanting survival rate of the Dendrobium officinale.

The invention relates to a river revetment ecological pollution filtering structure, in particular to a UHPC combined structure multifunctional ecological revetment system. Including steps and drainage grooves, the steps and drainage grooves are hollow box-type structures, multiple steps are installed in the shape of steps, and the drainage grooves are installed obliquely on one side of the step-like steps; the side of the steps is provided with drainage holes II, and the sides of the drainage grooves are connected with the drainage Drainage hole Ⅰ is set at the position corresponding to hole Ⅱ; the water in the step flows into the drainage groove through drainage hole Ⅱ and drainage hole Ⅰ, and the water is discharged through the inclined drainage groove; the material of the step and drainage groove is mixed with dichloride Cobalt UHPC. This application uses white cement, recycled colored glass powder, recycled colored glass particles, cobalt dichloride, etc. to prepare colorful UHPC materials that can predict the weather. It has good decorative functions. Cobalt dichloride will turn pink in rainy days. When dry, it will turn purple or blue due to different air humidity. It has the function of forecasting weather and can provide weather warning for tourists.

A class of carborane viologen derivatives and metallosupramolecular polymers thereof, synthesis method and application of the present invention, with viologen as the central core structure, synthesize 1,2-bis(4-pyridine) through Sonagashira coupling reaction Acetylene, then decanaborane attacks its alkyne group to synthesize carborane viologen precursor A, or uses decanaborane to attack the alkyne group in bis(4-bromophenyl) acetylene to synthesize bis(4-bromophenyl) ) carborane, and then synthesize carborane viologen precursor B through Still coupling reaction, and finally obtain carborane viologen derivatives through carborane viologen precursor A or B. Subsequently, viologen is used as the central core structure, carborane viologen derivatives and ruthenium trichloride, cobalt dichloride or ferrous acetate are used as reaction raw materials, and acetic acid is used as a solvent for reflux reaction, and the product in the final reaction solution Carborane viologen metal supramolecular polymers were synthesized after separation and drying.

The invention discloses a nano-powder method capable of preparing spinel-structured nano-cobalt ferrite CoFe2O4 at relatively low temperature. The preparation method of the nano-cobalt ferrite CoFe2O4 with spinel structure of the present invention is: after weighing iron trichloride and cobalt dichloride in proportion, mix and prepare aqueous solution A, prepare NaOH or KOH alkali solution, stir to Add N2H4.H2O dropwise to obtain solution B; quickly stir the aqueous solution A obtained in step 1 at 20~40°C, and slowly add the mixed solution B prepared in step 2) into aqueous solution A to react to obtain black Precipitation of cobalt ferrite CoFe2O4 powder with spinel structure.

The invention provides a preparation technology of cobaltocene. The preparation technology comprises the following steps: (1) reacting cobalt dichloride with a metal compound containing alkyloxy in an oxygen-free first alcoholic solvent to obtain a cobalt compound containing alkyloxy; (2) reacting the alkyloxy-containing cobalt compound obtained in the step (1) with a cyclopentadiene monomer in a second alcoholic solvent to obtain a mixed solution containing cobaltocene, and carrying out distillation to remove the solvent to obtain a coarse product of cobaltocene; (3) dissolving the cobaltocene coarse product obtained in the step (2) into a non-proton solvent, filtering, adding an ether solvent into the condensed filtrate, and carrying out recrystallization to obtain cobaltocene solids. The raw materials used in the provided preparation technology all have a wide source and low price. The reagents, which need strict reaction conditions, such as metal sodium, amino sodium, and the like, are not used in the provided preparation technology. Moreover, the reaction conditions are mild, the operation is convenient and safe, the production cost is low, thus the preparation technology is very suitable for industrial production, and the cobaltocene product is high-purity solid crystals.
