In April 2004, 30 Boleophthalmus pectinirostris samples were collected from the lagune in Xiepu Villege, Zhenhai Town, Ningbo City, Zhejiang Province. Polyarylamide gel electrophoresis was used to detect the expression of isozymes in liver tissue. LDH, FDH, GDH, GCDH, G6PDH, MDH, ME, SOD, CAT and EST were analyzed and the biochemical genetic results showed that, among the 10 isozymes in this paper, 9 of which obtained clear enzyme patterns except for CAT.

于2004年4月，在浙江省宁波市镇海区澥浦滩涂采集野生大弹涂鱼30尾，采用聚丙烯酰胺凝胶电泳方法，分析了乳酸脱氢酶、甲酸脱氢酶、谷氨酸脱氢酶、D-葡糖脱氢酶、葡萄糖－6-磷酸脱氢酶(G6PDH)、苹果酸脱氢酶、苹果酸酶、超氧化物歧化酶、过氧化氢酶和酯酶等10种酶在大弹涂鱼肝脏组织中的表达，并对同工酶表型进行了生化遗传分析。

Joseph Lister publishes his study of lactic fermentation of milk, demonstrating the specific cause of milk souring.

Joseph Lister发表了他关于牛奶乳酸发酵的研究，证明了是乳酸菌导致牛奶酸化。

The POLLA diblock copolymers were semi-crystalline copolymers, and the crystallinity was increased with the increase of LLA segments.

POLLA二嵌段共聚物具有结晶能力，且随着L型聚乳酸链段的增长而增强。

It was found that theintrduction of polar phosphatidylcholine to LLA chains had largely changed thehydrophilicity of the synthesized polymers. And from the research ofendothelioid cell (ECV304) compatibility and adhesion of blood platelet, wefound that the cells adhesion of ECV304 on the films of PLLA-PC-PLLA lagedcomparing to PLLA, but then could proliferate and cover the films in total,PLLA-PC-PLLA, the same as PLLA are not cytotoxicity and ECV304 canattach and proliferate on them, and PLLA-PC-PLLA can reduce the adhesion ofblood platelet.

结果表明：由于聚乳酸中磷脂酰胆碱结构的引入，使得该材料的亲水性得到很大的改善，并且随着聚合物中磷脂结构单元比例的增高其亲水性能就越好；通过对该材料进行细胞亲和性的实验研究，发现这种材料能够使细胞锚着并支持细胞的增殖；而血小板黏附的实验结果初步显示了该材料具有较好的抗血小板黏附的性质。

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。
