In order to reflect the toxicity of cadmiumin the two different systems: overlying water system and water-sediment coexistence system, the toxicological parameters such as metal body burden, MT and mortality in a freshwater cladoceran Daphnia magna after exposure were quantified.

选择大型溞作为受试生物，以大型溞体内金属积累量、金属硫蛋白含量和死亡率作为测试指标，考察了上覆水体系与水柱-沉积物共存体系中金属镉的毒性状况，探讨了水体沉积物中重金属的生物毒性作用机制。

The profile distributions of silicate, phosphate and nitrate suggest that the organic material decomposition in area is mainly through nitrification during early diagenesis. Based on benthic fluxes of nutrients calculated using Fick's first law, benthic fluxes of silicate, phosphate and nitrate are -886.45~42.62 mol/(m^2d),-3.04~5.83 mol/(m^2d) and -189.43~21.05 mol-(m^2d), respectively, and perhaps silicate and nitrate are one of the major sources of nutrients for bottom water. Our results also reveal temporal and spatial variations of benthic fluxes for silicate, phosphate and nitrate, which may be related to sedimentation environment changes caused by global climatologic change.

在水－沉积物介面附近矽酸盐、磷酸盐和硝酸盐都存在著极陡的浓度梯度，Fick扩散定理的计算结果表明，研究区内矽酸盐、磷酸盐和硝酸盐的海底扩散通量分别为-886.45～42.62mol/、-3.04～5.83mol/和-189.43～21.05mol/，且矽酸盐和硝酸盐主要是从沉积物向底层水体扩散，是底层水体营养盐的来源之一；研究区内矽酸盐、磷酸盐和硝酸盐的海底扩散通量存在著一定的时间和空间变化，这可能与因全球气候变化而导致的沉积环境的改变有关。

In this study the clubroot resistant CR DH line, susceptible inbred line 94SK of Chinese cabbage, the resistant and susceptible DNA bulks constructed from F2 individuals of CR DH line and 94SK were used to select the adaptive AFLP primer combination. AFLP analysis was performed with 256 Pst Ⅰ/Mse Ⅰ primer combinations.

为了筛选出大白菜适宜的AFLP引物组合，研究以抗根肿病大白菜双单倍体CR Shinki、感病自交系94SK及其后代F2构成的纯合抗病和纯合感病DNA混合池为材料，利用256对Pst Ⅰ/Mse Ⅰ引物组合进行了AFLP分析。

And VTMS is added in late stage of polymerization, in this situation the system has the lowest coagulum. When the hydroxyl value of such polymer increases, the coagulum decreases; and solid content of such polymer increases, the coagulum increases greatly, so it is difficult to get higher solid content emulsion.

采用正交实验方法，通过对有机硅改性丙烯酸乳液聚合过程中凝聚物含量、乳液粘度影响的研究，确定的最佳的反应条件是：以SLS/OP为乳化剂、比例为4/6、用量为2％、丙烯酸单体的用量1.5％、反应温度为75℃、改性剂VTMS用量是1.5％、改性剂后加入方式下聚合反应过程中有最低的凝聚物含量。

More levels of nano-SiO〓 lead to larger particle size. An increase in polymerization reaction temperature causes the decrease in coagulum and increase in viscosity and particle size, and the nano-SiO〓 has same effects at certain temperature. When the levels of hydrophilic monomer acrylic acid and hydroxylethyl methacrylate in core composite are increased, the particle size of emulsifier-free emulsion decreases, in spite of the presence of nano-SiO〓.

无皂乳液具有单分散性好、表面洁净、成本低廉、不影响产品性能的特点，首次研究了含或不含纳米粒子的含羟基和羧基的丙烯酸无皂乳液聚合，发现含或不含纳米粒子的无皂乳液聚合后的粒子粒径较大，具有单分散性；较多的纳米粒子导致较大的乳液粒径；反应温度升高，凝聚物含量下降，而乳液粘度和乳胶粒粒径增加，在相同的反应温度下，纳米粒子降低了聚合过程中的凝聚物含量，增加了乳液聚合物的粘度和粒径；不论纳米粒子是否存在，当无皂乳液核组成中亲水单体AA和HEMA用量增加时，乳胶粒粒径均减少。

With the increase of temperature, cobalt removal can be improved considerably.

研究结果表明，温度不同时，表面沉积物的结构也不同，表面沉积物的结构影响置换的速度。

RESULTS:①Cytocompatibility of PEG-PLA-PGL membranes with HUVECs: The observation result of phase contrast microscopy showed that, endothelial cells planted on the PEG-PLA-PGL membranes began to attach and stretch after being planted 4-6 hours. Three days later, cells grew in colonies rapidly, after 5 days, colonies began to fuse and seemed like cobble-stone. The cells were shuttle or polygon in shape after passages.

结果：①人脐静脉内皮细胞与聚乙二醇-聚乳酸-聚谷氨酸三嵌段共聚物膜片的细胞相容性：相差显微镜下种植在聚乙二醇-聚乳酸-聚谷氨酸三嵌段共聚物膜片上的细胞4~6 h后即开始贴壁、伸展，3 d后细胞开始呈集落样生长，生长较快，5 d后细胞集落开始融合，呈现特征性的鹅卵石样形态，经多次传代后，细胞呈长梭形或多角形，与对照组相比无明显差异。
