查询词典 activity

The immunoregulation activity of SPG-1 mainly existed in the part of sugar chain, but keeping its molecular structure intact had some effects on its immunoregulation activity; SPG sulphation had reducing effects on the immunoregulation of SPG-1, whereas, after medium and low acetification of SPG, the immunoregulation of SPG was enhanced. Conversely after high acetification, the immunoregulation of SPG-1 decreased, that is, after introducing sulfuric and acetic acid base in SPG-1, its immunoregulation changed. All of these indicated the structure of SPG-1 was closely connected with its immune activity.⑤.

甘薯糖蛋白SPG-1的免疫调节活性主要在其糖链部分，但保持分子结构的完整性对其免疫调节的活性有一定的作用；甘薯糖蛋白硫酸化对甘薯糖蛋白SPG-1的免疫调节有降低作用，而中、低度乙酰化后，可提高甘薯糖蛋白的免疫调节作用，高度乙酰化后则降低其免疫调节作用，即甘薯糖蛋白引入乙酰基和硫酸基团后，其免疫调节活性发生了改变，这些均表明了甘薯糖蛋白的结构与其免疫调节活性有密切的关系。

Combining the performance evaluation (activity, selectivity and stability) and the characterization of the catalysts (XRD, TPD, FTIR and the pore structure measure), it can be concluded that :(1)The activity of modified β is higher than MCM-22, but the selectivity of ethylbenzene is lower about 3% than that of MCM-22;(2)The mounts of diethylbenzene and the other by-products are higher 1.7 times and 1.5 times than these of MCM-22 respectively;(3)The catalytic performance of zeolite mixture is nearly equal to modified β, but the selectivity of ethylbenzene is higher about 0.5% than that of modified β;(4)The catalytic activity of zeolite is mainly correlated with the number of acid sites, strength and distribution, and the distribution of products is determined by the binding energy of ethylbenzene and the pore structure, while the stability of catalyst is affected by the amount of poly-ring aromatic alkylate and the pore structure.

以性能评价和特性表征（XRD、TPD、FTIR和孔结构测定）相结合的方式，对上述三种催化剂性能比较的结果表明：（1）改性的活性明显高于MCM-22，但乙苯选择性却低于MCM-22绝对差约3%；（2）改性(上二乙苯和其他副产物的生成量分别约为MCM-22上对应值的1.7和1.5倍左右；（3）混合型催化剂的性能与改性相仿，但乙苯选择性提高0.5%左右；（4）对乙苯合成，沸石催化剂的活性主要取决于其B酸中心数、酸强度及酸分布，产物分布则取决于催化剂表面的乙苯脱附能垒值和孔道结构，而稠环芳烃的生成量和催化剂孔道结构是影响催化剂稳定性的主要因素。

As the necessary choice of modern cultural creation, self-conscious symbol design always emerges as a specific cultural creation activity by human dealing with the relation to the outside objective symbolic world under specific historical conditions, which is a functional transcendent activity, a programmed cultural creation activity seeking for concreteness against abstractness, and it is also a cultural creation activity with self-discipline, compatibility, and pre-examination value with the ability of self-reflection, self-criticism, self-transcendence and self-creation, therefore, it is a choice of cultural practice which is helpful for us to guide contemporary human cultural creation according to complex situations and it is also one to further control the future and development trend of our culture.
