Above all, Staphylococcus aureus, Streptococcus agalactiae, and Escherichia coli are the main pathogens causing bovine subclinical mastitis; the bovine clinical mastitis is usually caused by Streptococcus agalactiae. Antibiotics such as Enrofloxacin, Erythromycin and Kita sermonic show effective on treatment; the preparation of Chinese traditional medicine has great potential on bovine mastitis treatment and should be widely spread.

实验结果说明：引起奶牛隐性型乳房炎的主要致病菌类型为无乳链球菌、金黄色葡萄球菌和大肠杆菌，引起临床型乳房炎的主要致病菌是无乳链球菌；抗生素中的恩诺沙星、红霉素、庆大霉素用来治疗奶牛乳房炎效果较理想，中药制剂在治疗乳房炎上应用潜力很大，应大力推广。

The temperature, moisture, pH value and titratable acidity, contents of protein and fat in whey and curd were measured, and the efficiency and yield were calculated.

试验结果表明：在排乳清和粉碎加盐阶段，干酪凝块中的水分含量变化幅度最大，排出乳清中的蛋白和脂肪数量明显增加；干酪的脂肪回收率达到92.22％。

Using DNA extracted by CTAB silicon-based method from leaves and endosperm of Torreya grandis, a silver staining-based AFLP system was established for leaves and endosperm respectively.

以香榧的叶片和胚乳为材料，利用改进的CTAB-硅珠吸附法提取DNA，分别就叶片与胚乳建立了香榧的AFLP银染反应体系。

The PVT emulsion as a kind of flocculants was applied to waste water treatment of paper mill, and the precipitation time and transmittancy were measured.

将 PVT乳液用于造纸废液的沉降处理，通过对沉降时间和透光度的测定可知，PVT乳液的用量为 0 。0 0 8%时，处理效果最好

There was correlation between blood urea nitrogen and milk urea nitrogen,so the changing of milk urea nitrogen could reflect the accommodate condition of rumen degraded protein,rumen undegraded protein and energy.

由于乳尿素氮含量和血浆尿素氮含量之间具有一定的相关性，众多研究表明，通过乳尿素氮含量的变化可以反应出瘤胃降解蛋白、过瘤胃蛋白及能量的供应情况。

Steeped corn endosperm and unsoaked corn endosperm were used respectively for zein extraction. The results indicated that steeping was helpful for the extraction.

分别用浸泡过的整粒玉米和胚乳及未经浸泡的胚乳提取玉米醇溶蛋白，结果表明，浸泡有利于醇溶蛋白的提取。

Results After six passages in BHK-21 cells, cytopathic effect was observed by microscopy. The rescued virus was rejuvenated once in unweaned mice, and then came back to cell passage. We found that the poly tract of rescued virus was shortened when the virus was passaged twice in BHK-21 cells. Although the data of LD50 in mice and TCID50 in BHK-21 cells showed that the virulence and infectivity of genetic engineering viruses were lower than its parental virus, no significant difference was observed between the genetic engineering viruses with the different length poly tract.

我们发现，基因工程毒在BHK-21上连续传代至第6代时，可见明显的致细胞病变效应(cytopathic effect，CPE)；在经过一代乳鼠接种之后再重新适应到BHK-21细胞的过程中，poly区段出现了缩短现象；乳鼠致病性试验和BHK-21细胞TCID50测定结果表明，尽管基因工程毒与母本毒相比毒力偏低，但含有不同长度poly的基因工程毒之间并无显著差异。
