鈣球體 的英文怎麼說
中文拼音 [gàiqiútǐ]
鈣球體
英文
calcospherite-
These investigations have found strong evidence for the former presence of 26al in the so - called refractory inclusions : tiny mineral assemblages, rich in calcium and aluminum, embedded in chondritic meteorites alongside the chondrules
這些研究發現了強而有力的證據，顯示鋁26曾經存在於所謂的耐火包體（富含鈣和鋁的細小礦物組合體，與球粒一起鑲埋在球粒隕石內） 。It is interesting that pma plus calcium ionophore a23187 can inhibit pma - induced pta1 expression, and this effect ca n ' t be reversed by calcmeurin inhibiter fk506. pta1 mabs can inhibit ctl activation and differentiation in mixed lymphocyte culture system when added at the beginning of the culture but can induce platelet activation and aggregation in the fc dependent manner. in 1997, pta1 cdna was cloned from cdna library of tpa activated jurkat cells, which belongs to immunoglobulin superfamily ( igsf ) with two v - like domains of extracelluar region of pta1
Il - 2 、 tnf - 、 pma可以使t細胞pta1表達上調， tgf -可以下調pta1的表達，而pma加上鈣離子載體a23187可以顯著抑制pma的上調作用，且這種抑制作用不被calcineurin抑制劑fk506所逆轉， 1997年burns教授從pma活化的jurkat細胞cdna文庫中克隆了pta1cdna全長，證實pta1是一個新分子，屬于免疫球蛋白超家族，胞膜外區有兩個v樣結構域。Abstract : by utlizing abundant local resource of ytirium and combining the characteristics of magnesium, barium, calcium and silicon, a sort of composite nodulizer - ytirium - based heavy rare earth nodulizer was developed which is characterized by its good desulphurizing and deoxidizing rate effect, excellent effect to neutralize anti - nodulizing effect of trace elements, strong nodulizng effect and degeneration - resistance, good effect to fine matrix structure, decreased chilling tendency and wide scope of applicatiom using this nodulizer to produce some important castings such as water - cooled wall of blast furnace and roller could increase mechanical properties of central area and casting yield
文摘:利用江西省豐富的釔基重稀土，結合鎂、鋇、硅、鈣等元素的特性開發了釔基重稀土復合球化劑，該球化劑具有脫硫、脫氧、抗干擾元素、球化和抗球化衰退能力強，細化基體組織，白口傾向小，適用范圍寬等特點，應用於高爐冷卻壁，軋輥等關鍵鑄件上可提高心部力學性能和工藝出品率。
