Abstract: The present disclosure provides a strip flatness prediction method considering lateral spread during rolling. The method includes: step 1: acquiring strip parameters, roll parameters and rolling process parameters; step 2: introducing a change factor of a lateral thickness difference before and after rolling and a lateral spread factor by considering lateral metal flow, and constructing a strip flatness prediction model based on the coupling of flatness, crown and lateral spread; step 3: constructing a three-dimensional (3D) finite element model (FEM) of a rolling mill and a strip, simulating strip rolling by the 3D FEM, extracting lateral displacement and thickness data of the strip during a stable rolling stage, calculating parameters of the strip flatness prediction model based on the coupling of flatness, crown and lateral spread; and step 4: predicting the flatness of the strip by the strip flatness prediction model based on the coupling of flatness, crown and lateral spread.

Abstract: The present disclosure provides an ultrasonic-microwave synergistic extraction method of total saponins in beautiful millettia root, comprising the following steps: S1, material treatment, S2, cold soaking, S3 enzymatic hydrolysis, S4 extract extraction, and S5 ultrasonic-microwave synergistic extraction. The extraction method of the present disclosure extracts relatively high content of total saponins, and has relatively high yield of saponins and low content of impurities, and each step acts synergistically to solve the problems of relatively low total saponin content, more impumayrities and bubbling in the extraction process.

Abstract: A method for producing ?? T cells modified by a chimeric antigen receptor, comprising: transfecting K562 cells with shFPPS targeted to FPP synthase by means of a lentiviral vector, such that the expression of FPPS in the K562 cells is lowered and a K562-shFPPS cell line with reduced FPPS expression is constructed; adding the K562-shFPPS cell line into a ?? T cell culture system for co-culturing with the ?? T cells, wherein it is found that the K562-shFPPS cell line can facilitate in vitro differentiation and proliferation of the ?? T cells; and adding a CAR-expressing lentiviral vector to the ?? T cell culture system comprising the cell line for co-culturing, wherein it is found that the K562-shFPPS cell line can further effectively improve the transfection rate of CAR genes. The provided solution effectively overcomes the technical challenge of the large-scale production of CAR-?? T cells, and has a good application prospect.
