Discussion the Aseptic Examine Verified Technic of the Methanesulfonic Acid Ropivacaine Injection Liquid 甲磺酸罗哌卡因注射液无菌检查方法验证的探讨
New aseptic monomethyl fumarate was synthesized by esterification of fumaric acid and methanol in the presence of TiSiW12O40/ TiO2. The effect of the molar ratio of alcohol to acid, the quantity of catalyst, reaction temperature and the reaction time were tested through orthogonal experiment. 以TiSiW12O40/TiO2为催化剂,用富马酸与甲醇直接酯化合成了防霉剂富马酸单甲酯(MMF),通过正交试验确定了醇酸物质的量比、催化剂用量、反应温度和反应时间对反应产率的影响。
Taking the tender bud under the aseptic condition as the explant, experiments were carried out to study the effects of different exogenous hormones, cane sugar and ascorbic acid on proliferation of cluster buds. 以木本切花植物极美泰洛泊在无菌条件下发芽所得的幼芽为外植体,采用正交设计试验,研究了不同水平的6-BA、NAA外源激素,蔗糖、抗坏血酸对极美泰洛泊幼芽丛芽的增殖效果。
