The invention relates to the light reflection material technology field and provides a micron order prism pyramid monomer and a manufacturing method thereof. The prism pyramid is capable of accommodating both the light flashing and light reflecting effects, and can exist independently without being attached to a carrier film. Only with adhesive glue, oil painting, hair glue and nail polishing oil and other colorless or colored transparent fluid or liquid media, it is possible to let the prism pyramid monomer to be attached on objects such as films, cloth, wires and plates requiring to be added with light or to realize light flash so that these materials can present the lighting effect. The monomer can be applied widely in great practical use, and the manufacturing method for the monomer is also simple and easy to implement. Therefore, with the method, batched monomer can be produced and used.

The invention provides a pre-lithiation method and device for negative pole pieces of a lithium-ion battery. The method comprises the steps as follows: firstly, the negative pole pieces and metal lithium pieces are sequentially immersed into an electrolyte at intervals in an inert atmosphere condition; the negative pole pieces correspond to the metal lithium pieces one by one but are not in contact with the metal lithium pieces; the negative pole pieces and the metal lithium pieces are connected with a positive electrode and a negative electrode of a power supply through leads respectively; the negative pole pieces are charged; the charging current is 0.05-2.0C; and the negative pole pieces are taken out and dried to obtain the pre-lithiated negative pole pieces. According to the pre-lithiation method and device, 'wet pre-lithiation' is adopted; the cost is low; the production security is high; the pole pieces can be evenly pre-lithiated; and the first efficiency and the energy density of the battery are improved.

The invention provides a production method of low-alloy and high-strength thick plates, and the production method comprises the following steps: after electric furnace smelting is performed, carrying out LF (Ladle Furnace) refining and VD (Vacuum Degassing), controlling the casting temperature and casting time of a body and a cap, after steel ingots are cooled, quickly demoulding the steel ingots, carrying out heat preservation on the cap by using a heat-holding cover, and cooling the steel ingots in a cooling device; putting the steel ingots into a furnace when the furnace temperature is 600-700 DEG C, after tightly covering the steel ingots for 5-8 hours, heating the steel ingots to 1150 DEG C at a speed of 40-60 DEG C / h and carrying out heat preservation on the steel ingots, and freely heating the steel ingots to1180-1220 DEG C 5 hours before rolling; carrying out axial rolling on the steel ingot firstly so as to eliminate tapers, wherein the starting rolling temperature is greater than 1150 DEG C, the finish rolling temperature is 850-950 DEG C, the total reduction rate is greater than 50%, the slow cooling stacking temperature is not less than 500 DEG C, and the slow cooling time is not less than 48 hours; carrying out normalizing treatment on rolled steel plates at a temperature of 880-920 DEG C, and carrying out heat preservation on the steel plates at a speed of 1.9-2.25 mm / min. The mechanical properties, especially Z-direction properties, of super-thick steel plates produced by using the method disclosed by the invention completely meet the requirements, the yield strength Rel of the steel plate is greater than or equal to 300 MPa, the percentage reduction of cross sectional area Z is greater than to equal to 50%, the qualified rate of flaw detection is over 90%, and the production cost of the steel plate is low.

The invention discloses a lower alcohol detecting probe, and a preparation method and application of the detecting probe, and belongs to the technical field of analytical chemistry detection. The lower alcohol detecting probe has a general formula shown in the description, in which R1 represents a hydrogen atom, R2 represents a nitrogen atom or a group shown in the description and R3 represents a hydrogen atom or a methoxy group. Probe molecules of the lower alcohol detecting probe are made into a detecting plate, the detecting plate turns red or pink after being reacted with lower alcohol, and the phenomenon is obvious and can be recognized by naked eyes; the lower alcohol detecting probe is convenient for use and low in cost, can be directly used for detecting lower alcohol in a solution, can detect lower alcohol rapidly and in real time, is suitable for being used in large scale actual production, and has a good application prospect in the environmental protection field; and the lower alcohol detecting probe avoids the problem that professionals need to use professional tools and software for a long time to obtain results by means of large-scale equipment.

The invention discloses a method for inducing the development of natural tetraploid loach male nucleus in a cold shock way. The method has the advantages that the ovum inactivation and the chromosome doubling treatment are not needed, the male nucleus development diploid loach can be fast and efficiently produced, and in addition, the hatching rate is high. The method is sequentially implemented according to the following steps that the natural male tetraploid loach and female diploid loach are taken for hastening parturition, the semen of the male tetraploid loach and the ovum of the female diploid loach are respectively taken, the obtained semen is diluted by Kurokura's solution for 100 times for use, the diluted semen is mixed with the ovum to form fertilized ovum, and the fertilized ovum is placed into ice water being 3 DEG C to be soaked for 60 minutes and is then placed into normal temperature water for hatching.
