The invention discloses an intermediate roll setting method, device, equipment and medium, and the method comprises the following steps: according to the width of to-be-rolled strip steel, determining a first distance between the edge part of the to-be-rolled strip steel and the taper angle of a first intermediate roll when the to-be-rolled strip steel is placed among a plurality of first intermediate rolls of a sendzimir mill; adjusting the first distance according to a target factor to obtain a second distance; the target factors comprise at least one of the thickness, the type, the coil shape and the target plate shape of the to-be-rolled strip steel and the roll shape of a working roll in the Sendzimir mill; and according to the second distance and the cone body length of the first middle rollers, the roll shifting values corresponding to the first middle rollers are determined when the Sendzimir mill rolls the to-be-rolled strip steel in the first pass. The roll shifting value determined ...

Phosphorylated and/or glycosylated protein or peptide one-step enrichment modification determination method

The invention discloses a phosphorylated and/or glycosylated protein or peptide one-step enrichment modification determination method. The method includes the following steps: 1) modification on end alkynyl or triazon of protein or peptide; 2) resin capturing of protein or peptide with modified end alkynyl; 3) cutting of the peptide/protein with modified alkynyl on resin. The protein or peptide enrichment modification determination method provided by the invention not only can enrich and purify the modified protein or peptide after translation but also can add one molecule segment on the protein or peptide, and the molecule segment has the functions of mass spectrum label and mass spectrum signal gain. The method has wide application prospect in the science analysis field.

Anticorrosive, abrasion-proof and rolling-resistant ground for garbage discharging hall, and construction method of anticorrosive, abrasion-proof and rolling-resistant ground

The invention relates to an anticorrosive, abrasion-proof and rolling-resistant ground for a garbage discharging hall, and a construction method of the anticorrosive, abrasion-proof and rolling-resistant ground. The ground comprises a reinforced concrete structure layer (5) at a bottom, wherein an emery abrasion-proof layer (4), a middle cement-based crystallization layer (3), a carbamide resin-based layer (2) and a carbamide resin surface layer (1) are also arranged on the reinforced concrete structure layer (5) successively. The construction method comprises the following five steps in a layered construction manner from bottom to top: performing pouring, levelling, jolt ramming, calendering and forming at a time on the reinforced concrete structure layer (5); before prehardening, spreading dry nonmetal emery to form the emery abrasion-proof layer (4); performing brushing or roll painting with cement-based crystallization permeable crystallization paint to form the middle cement-based ...

Buffer distribution method and apparatus

The method includes following steps: setting up default space of buffer memory; obtaining length of data to be stored, and available buffer space; when length of data to be stored is larger than available buffer space, expanding default space of buffer memory according to prearranged expanding rules; when length of data to be stored is smaller than available buffer space, reducing default space of buffer memory according to prearranged reducing rules. The disclosed device includes following units: parameter maintenance unit, unit for capturing buffer space, comparing unit, buffer adjustment unit, buffer allocation unit. The invention avoids overflow of data and waste of space of buffer memory, and reduces frequency of dynamic adjustment so as to raise integral efficiency of system.
