The removal of these impurities by three kinds of active carbon(coaly activated carbon,fruit hull activated carbon,woodiness activated carbon) are studied under different experimental conditions.The results show that the fruit hull active carbon is not suitable for the removal of the impurity in bittern of salt lake because its removing rate of COD and turbidity is ...

以去除盐湖卤水中COD和浊度为目的，选用煤质活性炭、果壳活性炭、木质活性炭3种不同活性炭进行净化除杂的工艺研究，结果表明：果壳活性炭对COD和浊度的去除率最低，加入量最大，不宜选用；木质活性炭在低温下(≤20℃)脱除COD效果较好，在常温下(28~45℃)去除COD和浊度的效率明显低于煤质活性炭；在震荡速度、吸附时间及吸附剂加入量均相同的情况下，煤质活性炭脱色除杂效果明显优于其余两种活性炭，在盐湖卤水的脱色净化工程中应优先选用。

南部喜马拉雅地区的壳幔形变主要受近垂直的边界转换断层和中地壳近水平的横向断层共同调节；高原内部则主要受近垂直的边界转换断层和壳—幔过渡带近水平横向断层的解耦联合制约。

In the Cryptocarya community, the reason for Cryptocarya concinna having high relative frequency and relative abundance is probably not it has wider range of resistance to soil variables but the range of its resistance has much wider spread in broad-leaf forest habitat, or it may just has a wider range of resistance to the limiting factor.

在厚壳桂群落，黄果厚壳桂之所以具有较高分布频度与多度，并非它对所有土壤因子具有较宽的容忍性，而可能是它能容忍的范围在阔叶林生境有较广的分布，或它仅对极限因子的容忍有较广的范围。

Nei'genetic distance showed Schima superba and Cryptocarya chinensis hadsmall genetic distance between every two subpopulations of each own,but Castanopsischinensis had high genetic distance between every two subpopulations of own.

Nei遗传距离结果表明，荷木和厚壳桂两两亚种群间都有非常小的遗传距离，而锥栗却有大的两两亚种群间遗传距离，表明荷木和厚壳桂亚种群间个体的差异小，有较少的位点频率发生变化；而锥栗亚种群间个体的差异大，有较多的位点频率发生变化。

The results of study show:1. White pulp and red pulp in parenchyma of spleen of embryo can be obviously discerned after 18 days. Periarterial lymphoid sheath and ellipsoid periarterial lymphoid sheath also can be obviously discerned in spleen of 4 days chicken. T, B lymphocytes in appendix basement of embryo emerge after 20 days. It is the initial shape of cecal tonsil. Crypt structure of conjunction of esophago and stomachus glandularis form obviously at 4 days. It is the initial shape of esophago tonsil. The germinal center firstly emerges in these three organs at 14 days. With the increase of day age, the characteristic structure peripheral immune organs gradually develop mature. Spleen achieve mature at 21 days and cecal tonsil at 35 days.2. IgM~+ and IgA~+ cells in spleen of embryo emerge at 15 days. IgG~+ cell, CD3~+ and CD8~+T lymphocytes of embryo emerge at 20 days. CD3~+, CD8~+ and IgM~+ cells in cecal tonsil of embryo emerge at 20 days. However CD4~+, IgG~+ and IgA~+ cells all emerge in 1 day age chicken out of crust. CD3~+, CD4~+, CD8~+, IgM~+ and IgG~+ cells in esophago tonsil of embryo all emerge at 20 days. However IgA~+ cells emerge in 1 day age chicken out of crust.3. The amount of T, B lymphocytes in peripheral immune organs increase follow with the increase of day age, and hold an upgrade tendency. The amount of T, B lymphocytes in spleen achieved stabilization at 21 days, and in tonsil of esophago and appendix at 35 days.

研究结果表明：1、在组织结构方面，脾脏实质内的白髓与红髓在胚胎18日龄后明显可辨，4日龄雏鸡脾脏中形成明显可辨的动脉周围淋巴鞘和椭球周围淋巴鞘；盲肠基部T、B淋巴细胞在胚胎20日龄时开始出现，即初步形成盲肠扁桃体；食管与腺胃结合处在4日龄时形成明显的隐窝结构，即食管扁桃体初步形成；14日龄时，三种器官中首次出现生发中心；随着日龄的增长，外周免疫器官特征结构不断发育成熟，脾脏在21日龄时达到成熟水平，盲肠扁桃体和食管扁桃体在35日龄时达到成熟水平。2、在T、B淋巴细胞出现时间方面，脾脏中IgM~+和IgA~+细胞在胚胎15日龄时开始出现，IgG~+细胞、CD3~+和CD8~+T淋巴细胞在胚胎18日龄时出现，CD4~+细胞在胚胎20日龄时出现；盲肠扁桃体中CD3~+、CD8~+和IgM~+细胞在胚胎20日龄时开始出现，而CD4~+、IgG~+和IgA~+细胞均在雏鸡出壳后1日龄时出现；食管扁桃体中CD3~+、CD4~+、CD8~+、IgM~+和IgG~+细胞均在胚胎20日龄时开始出现，而IgA~+细胞则在雏鸡出壳后1日龄时出现。3、在T、B淋巴细胞数量变化方面，外周免疫器官中T、B淋巴细胞的数量随日龄增长，整体均呈上升趋势。

同时认为，对于抽锭式重熔过程来讲，结晶器与钢锭之间的相对移动，实际上是接触钢锭表面的渣壳内侧渣璧相对于被拉裂的与结晶器接触的渣壳外侧渣壁的剪切运动。

The result shows that the chitosan can increase the the amount of effective tiller, then the yield of both of cultivars of Zizania caduciflora is enhanced markedly, and the concentration of 45mg/L of the chitosan has the best effect. The activity of POD in leaves and the content of sucrose in product can be increased after using the chitosan, and the change of the chlorophyl content could be abated and the effect has a long duration, and the furthersome effect of chitosan on the activities of the CAT and the APX lasts in the prophase and the midphase of growth.

结果显示壳聚糖的使用对单季茭和双季茭的有效分蘖数都有增加作用，从而明显提高茭白产量，并且均以45mg/L的浓度效果最好，其使用能显著提高两种类型茭白生长期叶片中POD酶的活性以及茭体中的蔗糖含量；壳聚糖对茭白叶绿素有缓和变化波动的作用且持效久，对茭白CAT、APX酶活性的促进作用只在处理前中期有效；而对株高和A.A。

The binding capacities of the water-soluble chitosan and its derivatives to taurocholate and glycocholate as bile salts were investigated in vitro.

修饰后的壳聚糖结合胆酸盐的能力增强，说明引入更多的胺基或铵基有利于对胆酸盐的结合，胺基上烷基与胆酸盐的甾环之间也应当产生疏水相互作用；同样我们在体外也研究了水溶性壳聚糖及其衍生物对硬脂酸钠和十二烷基硫酸钠的结合能力及其影响因素。
