血清菌苗

Formalin and phenol and heat killed cells of Vibrio harveyi were prepared to show immunogenicity to Caressius auratus gibel by examination of agglutinating antibody litres of serum as well as phagocytic activity of blood leucocytes.

结果表明，3种方法制备的V.harveyi菌苗注射接种异育银鲫后第29d，受免异育银鲫血清中凝集抗体效价均不同程度地上升，其中以F一VH免疫组最高，P一VH免疫组其次，再次为H一VH免疫组。

Gibel carp were inoculated with formalin killed Aeromonas hydrophilaand fed with diets supplemented with appropriate amount of yeast β-glucan. 28 days after the inoculation, the infulence of dietary yeast β-glucan on the resistance of gibel carp against Aeromonas hydrophila were determined by examing their gained weight, agglutinating antibody titer, lysozyme activity, phagocytic activity and relative percent survival by challenging with live A.

在饲料中添加定量的酵母β-葡聚糖，投喂经注射接种福尔马林灭活的嗜水气单胞菌(Aeromonas hy-drophila)菌苗的异育银鲫28 d后，通过测定供试鱼的增重量、血清中凝集抗体效价、溶菌酶活性、谷丙转氨酶活性、血清总蛋白含量、白细胞吞噬活性以及活菌攻毒后的免疫保护率，探讨了酵母β-葡聚糖对受免异育银鲫免疫应答的增强作用。

The serotype of 66 strains of Vibrio harveyi isolated from large yellow croaker(Pseudodciaena crocea Richardson) infected by vibriosis was tested in this study. The juvenile large yellow croakers, which cultured in the cage in Xiangshan Bay , were vaccinated with formalin killed V.harveyi of the virulent strains by immerse route , The results were summarized as follow.

本文研究了从患病大黄鱼体内分离66株哈维氏弧菌(Vibrio.harveyi)的血清学性状，并选取了其中的强毒菌株制备成福尔马林灭活的V.harveyi菌苗，对象山港网箱养殖大黄鱼进行了浸泡免疫试验，探讨了V.harveyi的浸泡免疫保护效果，得到了如下研究结果。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
