查询词典 aging analysis

And it is expected to replace the expensive organic polymer coagulants which were often suspected of being dangerous to human.The preparation technique of HSPSAS was introduced in this paper. The parameters of the process were discussed by the method of orthogonal design, such as molar ratio of Al/Si, the pH of polysilicate, the aging time of polysilicate, the pH of PSAS, the aging time of PSAS, intake of PSAS, and so on, and then an optical technology was obtained.

本文介绍了聚硅酸硫酸铝絮凝剂的制备工艺，并利用正交设计的方法，对其中Al/Si摩尔比、硅酸熟化pH值、聚硅酸熟化时间、药品熟化pH、药品熟化时间、投药量等制备参数进行了分析和讨论，得到优化的制备条件，确定了更为合理的制备工艺。

This is a paper of probative Study about demographic aginggenerally,we call it population aging or aging of popu...

这是一项关于人口老龄化理论与现实的探索性研究。

In this part, the concepts of the aged and the population aging are explained distinctly, the development traits and trend of population aging in world and China are stated reasonedly.

然后分析了世界和中国人口老龄化的发展特点及趋势，为后文对山东省人口老龄化的分析奠定理论和实践基础。

Aging mechanism of wood-plastic composite was: light and heat break down the long molecular chains of wood flour and plastic; the free radicals reacted with the oxygen, which generated carbonyl groups, hydroperoxides and so on; the free radicals also had cross linking reaction, which generated alkoxy; Water destroyed the interface of wood flour and plastic, hydrolyzed ester additives, extracted the small molecule additives and degradation products; Microorganism degraded cellulose, semicellulose, lignin and ester additives; degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.

木塑复合材料的老化机理为：光和热引发木塑复合材料中木质组分和塑料组分大分子链断裂，产生的自由基与氧气作用，发生链支化反应生成羰基、氢过氧化物等，发生交联反应生成烷氧基等；水分破坏木-塑界面、水解酯类添加剂、抽提小分子添加剂和降解产物；微生物分解纤维素、半纤维素、木素和酯类添加剂；木塑复合材料中各组分的降解产物相互促进老化，PVC降解产生的HCl溶于水，促进了纤维素和半纤维素的水解。

Results: The ratio of I and Ⅲ collagen fibers in the sinoatrial nod increased with aging. Type I was the majority while type Ⅲ decreased during aging.

结果：窦房结胶原纤维随年龄的增高有增高的趋势，发现胶原纤维以1型为主，3型胶原纤维随年龄的增高有减少的趋势。

Erwinieae, Plesiomonas, Aeromonas bacteria lived as endophytic bacteria during the first three period, these dominantbacteria led to important action in the chemical components degrading of sugar, starch , protein, pectin and the conversion from nitrate to nitrite, and this was the basic of aging. The dominant bacteria during aging was sporeformer which had high resistance.

欧文氏菌属、邻单胞菌属、气单胞菌属细菌作为内生细菌在前三个时期一直存在，这些优势菌在烟叶这三个时期的糖类、淀粉、蛋白质、果胶质、等化学成分的降解和硝酸盐到亚硝酸盐的转化中可能起到重要作用，对烟叶陈化初期质量打下基础。

Methods40 SD rats were divided into 4 groups at random: normal group, aging model group, Tiannianyin group and negative control group, each group had 10 rats. The subacutely aging model rats were made by injecting D-gal into abdominal cavity continually.

方法40只SD大鼠随机分为4组，正常组、衰老模型组、天年饮用药组及阴性对照组，每组均为10只。D半乳糖连续腹腔注射制作亚急性衰老的大鼠模型。

Methods40 adult male SD rats were used in this study and divided into 4 groups at random: normal group, aging model group, TNY treatment group, and negative control group, each group had 10 rats. The subacutely aging rats were made by injecting Dgal into the rats' abdominal cavity continuosly. The learning and memory ability of rats in each group were detected with Morris water maze. The monoamine transmitter contents in hypothalamus and hippocampus were detected with HPLCECD.

方法选用成年雄性SD大鼠40只，随机分为4组，每组10只：正常组、衰老模型组、TNY用药组、阴性对照组。D半乳糖连续腹腔注射制作亚急性衰老的大鼠模型，采用Morris水迷宫检测各组大鼠的空间学习记忆能力及采用高效液相色谱电化学法检测各组大鼠下丘脑、海马NE，DA，5HT的含量。

结果表明，随着钴盐用量的增大，在未老化、热空气老化及盐水老化条件下，胶料与钢丝的粘合强度有所提高；在湿热老化条件下，粘合强度由于热量和湿气的交互作用而发生较大幅度的下降，但钴盐用量在10份时粘合强度的下降为最小。综合胶料初始和老化后的应力应变性能和粘合强度，以10份钴盐用量为最佳。
