In this paper, we studied the effect of sterilization on different bacteria and cyanobacteria in variant water sample of micro-electrolysis and high voltage electrostatic field, and the effect of physiological activity on E.coli and the characteristic optical absorption peak of phycocyanin of micro-electrolysis. The mechanism of sterilization and algae killing was approached.

Through experiment on the nutrient contribution in fish diet,thefeeding custom of dolphins was concluded,that was in winter,dolphinslike to eat fish with high energy,such as houttuyn;in summer,dolphinsturn to like fish with low energy,such as ribbonfish and polynemidae.Based on it,scientific feeding system and other relatively husbandrymethods were preliminary formed.

2通过对海豚的每一批饵料鱼体营养成分的测定分析(粗蛋白、粗脂肪、灰分、水分和总细菌数)，进而通过对海豚的食性、日食量及食前反应、食后反应等方面的研究，发现了海豚的季节性饮食喜好规律，即海豚在冬天喜欢采食鲐鱼等高能量型鱼类，在夏天喜欢采食带鱼等低能量型鱼类，首次建立了海豚的饵料投喂、营养补充物质的适量添加及定期进行驱虫、接种疫苗和体格检查等科学饲养管理方法体系。

After further screening, these sericin degradation bacteria can be used to treat the waste water of a reeling mill.

分离这些丝胶蛋白降解细菌是为了进一步筛选后用于制丝厂的废水处理。

Aphids in the process of inhaling plant sap virus particles and auxiliary proteins also be inhaled, thus completing the process by poison, which also supports the field citrus aphid is non-persistent decline disease vector of disease, while the citrus Huanglongbing is phloem restricted by the bacteria caused the main pathogens present in the phloem, the fleas only by phloem feeding in diseased plants, pathogens in the body through the back to complete the salivary glands in the course of the next through the sieve tube feeding in the secretion of saliva the pathogens into the healthy tree, Citrus Huanglongbing different characteristics with aphid-borne diseases, Huanglongbing to persistent disease.

蚜虫在吸入植物汁液的过程中病毒粒子和辅蛋白同时也被吸入，从而完成获毒过程，这也支持了田间蚜虫是柑桔衰退病等非持久性病害传播介体，而柑桔黄龙病是由韧皮部限制性细菌类引起，病原体主要存在于韧皮部中，木虱只有通过在病株韧皮部取食，病原在体内完成循回到唾液腺中，在下一次取食过程中通过在筛管中分泌的唾液将病原体带到健树，柑桔黄龙病与蚜虫传病特点不同，黄龙病为持久性病害。

Urease may reach as much as 10% of total bacterial protein.

尿素酶占细菌总蛋白的10％左右。

P 0.05. Total ruminal bacteria, proteolytic and amylolytic bacteria, and protozoa in rumen enumerated by culture method all increased (P 0.05) in the Trial period. Real-time PCR analysis was used to compare Pre-trial and Trial populations of cellulolytic species, including Butyrivibrio fibrisolvens, Ruminococcus flavefaciens and Ruminococcus albus, which were increased by 7.0, 4.5 and 9.6%(P 0.05), respectively. Two starch-fermenting bacteria species, Streptococcus bovis and Ruminobacter amylophilus, were increased by 25.4% and 14.6%(P 0.05), respectively.

3.02，P 0.05。传统培养法结果表明，与对照期相比，BSN2处理期奶牛瘤胃中瘤胃细菌、蛋白分解菌、淀粉分解菌和原虫数量显著增加；实时定量PCR结果表明，试验期奶牛瘤胃纤维分解菌，包括溶纤维丁酸弧菌、黄色瘤胃球菌和白色瘤胃球菌数量分别提高6.97%、4.51%和9.6%(P 0.05)，两种淀粉分解菌，牛链球菌和嗜淀粉瘤胃杆菌分别提高25.4%和14.6%(P 0.05)，乳酸利用菌埃氏巨球型菌也提高8.85%(P 0.05)。

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