Observations on Ovine Immune Effects of FMDV O-Asia 1 Type Bivalence Vaccine ( A Preliminary Report) 口蹄疫O-AsiaⅠ型二价疫苗对羔羊免疫效果的观察(初报)
Applying principal of topotactic reaction in the same crystal class, in the presence of bivalence metal ion and preventing from air oxidizing, the dust was transferred to spinal ferrite MnFe_2O_4. The magnetic properties of spinel ferrite MnFe_2O_4 were studies, but magnetic hysteresis loop were determined. 在有二价Mn2+离子存在及避免氧化的条件下,将平炉尘转化为超细尖晶石型铁酸盐MnFe2O4。并对其磁性进行了研究,测定了磁滞回线。
Succeeded in using mice replacement of rabbit to test bivalence vaccine efficacy, and this method can reduce reduce test cost, and more sensitive, specific, objective and simple. 以实验动物小白鼠代替本动物进行二价疫苗效力检验取得成功,本效力检验方法可降低检验成本,具有更敏感、更特异、更客观、更简便等特点。
The first section, revolving around four points of contention between Davidson and Dummett, that is theoretical starting point, radical interpretation or not, attitude toward the principle of bivalence and kernel concept choice, offers a thorough analysis. 第一节分析研究戴维森、达米特意义理论的争论点。论文从构建意义理论的出发点、意义理论彻底解释与否、对二值原则的态度及核心概念的选择这四个争论点进行剖析。
Ranelic acid, an organic acid with strong polar and without pharmacological activity, can form stable chelate compound with bivalence Sr ion. 雷尼酸是强极性的有机酸,无药理活性,但能与二价锶离子形成稳定的螯合物。
