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。

Based on the theory of shrinkage, capillary force theory, the influence of road concrete additives in common use on surface tension of water is studied, and the results show that the influence of water reducer is very small whereas shrinkage-reducing agent and air entrainer can reduce surface tension of solution significantly. The relation between surface tension and additive dosage are non-linear relation. Each additive has an obvious critical micelle concentration.

从混凝土收缩的基本理论——毛细管张力理论出发，通过道路混凝土外加剂对水的表面张力的影响研究发现，减水剂对水的表面张力的影响很小，而减缩剂和引气剂可以大幅度降低溶液的表面张力，溶液的表面张力随外加剂的掺量呈非线性形式降低，而且都存在临界胶束浓度。

Adeline's father, stepmother and their two children were the upper class, whereas Adeline and the four other step-children by the first wife were considered second class.

And the result is that, whereas the _Iliad_ or _Odyssey_ supplies materials for only one, or at most two tragedies, the _Cypria_ does that for several, and the _Little_ _Iliad_ for more than eight: for an _Adjudgment of Arms_, a _Philoctetes_, a _Neoptolemus_, a _Eurypylus_, a _Ulysses as Beggar_, a _Laconian Women_, a _Fall of Ilium_, and a _Departure of the Fleet_; as also a _Sinon_, and _Women of Troy_.

然而结果是《伊利亚特》和《奥德赛》只能为一部，至多两部悲剧提供素材，而《塞浦路斯人》可以提供好几部，《小伊利亚特》可以多至八部：《甲胃的审判》、《菲罗克忒忒斯》、《涅俄普托勒摩斯》、《欧律皮洛斯》、《乞丐奥德赛》、《拉哥尼亚妇女》、《特洛伊沦陷》和《船队离港》，甚至还可以写出《西农》和《特洛伊妇女》。

The results indicated:0.1 mg/L 2,4-D or 0.1 mg/L 2,4-D+0.2 mg/L KT was optimal to induct the callus of carrot hypocotyls.The majority of the callus induced on the medium containing 0.1 mg/L 2,4-D regenerated embryoid,whereas,the callus induced on the medium containing 0.1 mg/L (2,4-D)+0.2 mg/L KT produced adventive buds.During the growth of regenerated plant,MS medium is available for rooting of seedling,and seedling regenerated on B5 medium must be placed on the B5 medium containing 0.1% IBA to develop root.

试验结果表明：0 1mg/L2，4 D或0 1mg/L2，4 D+0 2mg/LKT的激素组合有利于胡萝卜下胚轴的愈伤组织诱导；在0 1mg/L2，4 D的培养基上形成的愈伤组织主要以胚状体的形式再生，而在含0 1mg/L2，4 D+0 2mg/LKT激素组合的培养基上形成的愈伤组织主要以发生不定芽的方式再生；再生过程中，B5基本培养基上的苗子不易生根，需要附加0 1mg/L的IBA，而在MS培养基上苗子可直接形成根。
