Abstract: The present disclosure provides an in vitro proliferation medium, an in vitro culture kit and an in vitro proliferation culture method of umbilical cord blood (UCB)-derived natural killer (NK) cells, and relates to the technical field of cell in vitro culture. In the present disclosure, the in vitro proliferation medium does not include animal serum to reduce immune responses when being used, with better safety. The in vitro proliferation medium is used to proliferate the UCB-derived NK cells in vitro, with simple and easy operations and low cost, and without coating, sorting and trophoblast cells. The medium does not include animal-derived ingredients, and has desirable safety and stability. The medium can be used for direct culture of peripheral blood mononuclear cells (PBMCs) isolated by Ficoll, and harvest more NK cells that meet clinical use standards.

Abstract: Disclosed in the present invention are ABS rubber powder with a low impurity content, a preparation method therefor, and an ABS resin. The ABS rubber powder is treated by using the following steps: washing the ABS rubber powder with a washing solution I, and monitoring the content of soluble organic carbon in the ABS rubber powder until the content of soluble organic carbon in the ABS rubber powder is less than or equal to 9000 ppm, so as to obtain the ABS rubber powder with the low impurity content. In the present invention, by controlling the content of soluble organic carbon or the contents of soluble organic carbon and iron ions in the ABS powder, the ABS resin with a low yellow index of less than or equal to 18 is obtained.

Abstract: The invention discloses a drill bit design method based on rock crushing principle with local variable strength, including: drill bit is divided into local crushing feature regions; strength mode factors of the local crushing feature regions are calculated; a difference among strength mode factors of the local crushing feature regions is obtained to obtain a vector sum of horizontal cutting forces of the drill bit tooth corresponding to the same group of cutting tooth on the drill bit; treating the difference among the strength mode factors of the local crushing feature region as a target control condition for drill bit design. Based on the rock crushing principle with local variable strength, after dividing the symmetrical cutting tooth into groups, the strength variation factors of the symmetrical position are adjusted and balanced, so that the rock crushing strength of different local crushing feature regions can be changed in a targeted manner.
