In this paper, we first analyze the mechanism of action potential propagated alongan unmyelinated fiber, and present a hypothesis that the velocity of transmembranecurrent is the equivalent of the propagation velocity of action potential. Then usingthe H-H model and the cable equation we obtain the formula of the velocity. Insuccession, we apply a similar method to analyze the mechanism of action potentialpropagated along a myelinated fiber. Using the McNeal model and the CRRSS model,we obtain the formula of the velocity.

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。

With two methods, plate cultivation and the novel semi-solid in situ cultivation method, strains belong to Family Leptothrix were isolated. XRF showed that the amorphous iron and manganese were two major metal elements of the precipitation formed by one strain of Leptothrix spp..

研究发现，铁细菌2号培养基为合适的分离培养基；采用平板涂布法分离出的2株氧化铁和锰的细菌，经系统发育地位的分析确定为纤发菌属；对运动纤发菌的产物分析确定无定形铁和锰为其主要金属元素；形态观察确定霍氏纤发菌呈树枝状鞘结构，而运动纤发菌呈蛛网状鞘结构。

This observation provided a strong support to the point that most leaves export the most of assimilates in the light time. Plasmodesmal densities between SE/CC, CC/PP, PP/PP and PP/BSC (bundle-sheath cell) decreased in weak light. Plasmodesmata were observed between CC/SE (nacreous-walled sieve element), PP/BSC in branch veins in normal light intensity, but not in weak light. Thus apoplasmic pathway may be the main mode of transport of assimilates in weak light, however symplasmic pathway may be the main mode of transport of assimilates in normal light intensity.

在筛管/伴胞、伴胞/韧皮薄壁细胞、韧皮薄壁细胞/韧皮薄壁细胞和韧皮薄壁细胞/维管束鞘细胞之间的胞间连丝密度都在弱光条件下下降，在正常光照强度下支脉筛管/伴胞和韧皮薄壁细胞/维管束鞘细胞之间可以观察到胞间连丝，而在弱光下几乎观察不到胞间连丝的存在，所以同化物的运输在弱光条件下可能以质外体运输为主，而在正常光照强度下，共质体运输可能是主要的运输方式。
