查询词典 polar axis

Storage battery is emergency power supply of DC operation electrical source system in electrical power system, whose good work state, is great important to operation of fixture. Because individual storage battery quickly abates due to dry, heat, polar plate lithification, weeping, lack charging, excessive discharging, internal resistance increasing, capability reduction, explosion etc., heavy accident of electric network impossible occur.

蓄电池是电力系统直流操作电源系统的后备电源，它的工作状态好坏，对于设备的运行至关重要，由于运行中个别蓄电池会因干涸发热、极板岩化、漏液、欠充、过放、内阻增大、容量降低、爆炸等原因而迅速失效，极有可能造成电网的重大事故。

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。

The chemical constituents of Huperzia serrata Trev. are mainly flavonoids, triterpenoids and alkaloids. In order to get further comprehension of lycopodium alkaloids, we studied the low-polar section of the alkaloids extraction of Huperzia serrata and 19 alkaloids were isolated by ways of silica gel, RP-18 and Sephadex LH-20 etc. All of their structures, including five new compounds and two known ones that were firstly found from this genus, were elucidated with the help of Mass, IR, NMR spectra and so on. The five new alkaloids (HS-07, HS-08, HS-09, HS-10 and HS-11) are belonged to lycopodine class. The other two ones that were new to this genus (HS-18 and HS-19) are belonged to miscellaneous group.
