With the Eu doping level increased to more than 1mol%, the content of B-site occupancies is increased and acceptor doping is to be dominant.

当Eu含量低于1mol％时，Eu在PZT晶格中主要占A位，起施主掺杂作用；随着Eu含量的增加，其在PZT晶格中占据B位的比例逐渐增多，受主掺杂作用逐渐增强。

Japonicus and analyzed the role of animal process of oocyte during ovulation and oocyte maturation. What's more, we studied the role of microtubules and microtubule organizing center upon GV migration. The oocyte of A. japonicus connects to the follicle via animal pole process. When placed in normal sea water, ovulation started spontaneously.

利用DTT诱导刺参卵母细胞成熟，综合运用光镜、电子显微镜及激光共聚焦技术观察卵母细胞成熟过程，分析了卵母细胞表面动物极突起在卵母细胞脱滤泡中的作用，以及卵母细胞动物极突起和微管组织在生发泡移动过程中所起的作用。

Optimum extraction conditions were selected by the condition experiments and the concentration of Cu, Pb, Zn in main components were also determined for revealing the distribution of the heavy metals in the suspended particulate matters. It was found that hydroxylamine hydrochloride (0.006 mol/L NH2OH·HCl+0.01 mol/L HNO3) can remove most of Mn oxides, and sodium dithionite 0.8 mol/L Na2S2O4

结果表明，0.006 mol/L NH2OH·HCl+0.01 mol/L HNO3萃取30 min可以单独萃取悬浮颗粒物中大部分的锰氧化物，0.8 mol/L Na2S2O4（pH=6.0）萃取40 min可以同时萃取铁、锰氧化物，而对非目的组分的影响较小；悬浮颗粒物对Cu、Pb、Zn重金属有明显的富集作用，其中Cu主要结合在悬浮颗粒物的有机质组分中，Pb主要富集在铁、锰氧化物中，锰氧化物和有机质对Zn的分布起主要的富集作用。

Effect of inoculation with phosphate-solubilizing bacteria and soil acidification on the growth of Stylosanthes guianensis Reyan No.2

我国地表水体污染普遍严重，水环境生态质量不断恶化，影响水体正常使用功能；另外，沉积物中磷的再释放是影响水体水质的重要原因，而沉积物中的磷细菌对磷的吸收、贮存和释放在磷循环中起着极其重要的作用，为此本研究针对地表水体水质改善技术及沉积物中磷细菌作用分别进行了研究，并选择在杭州市内河进行了水质改善的技术实践，主要成果如下：(1)在室内模拟条件下，分别设置了高溶解氧7。

In ancient prose times, it plays positive effect to the development and process of one nation, with instructing the behavior and forming value of people. It still brings into play of standardizing life and unifying education in modern times, and it implies profound pedagogy significance,embodying five facets, that is, helping to the cultivation of ethos, favoring the advance of the moral ambit, bearing the sole teaching means, vailing the medium of diffusing traditional culture, including of educational folk-custom.

不仅在古文明时代，对一个民族的发展和进步起着积极的作用，用以指导人们的行为举止，形成人们的价值观念；即使在现代文明社会仍然发挥着规范人生和统一教化的作用，蕴涵着深刻的教育学意义，体现在五个方面的：有助于民族精神的培养、有利于道德境界的提升、是具有独特教化手段的教育资源、是传统文化传承的媒介、包含丰富的教育民俗。
