Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.

本研究观察了从鸡胚到出壳后的不同生长发育阶段法氏囊的组织结构，结果表明：胚胎13日龄时，法氏囊开始发育，粘膜上皮下形成结节状细胞集团；胚胎15日龄，聚集的细胞集团形成初始的淋巴滤泡；胚胎18日龄到出壳后1日龄，滤泡内淋巴细胞数量增多，多数滤泡髓质和皮质界限仍不明显；7日龄雏鸡法氏囊髓质皮质分界清晰，滤泡数量显著增多；21日龄到35日龄，滤泡由多边形逐渐转变成长方形；在35日龄时，粘膜上皮细胞逐渐增多，排列紧密，细胞核紧密排列成直线位于基底部。

The paper are studied dynamics characteristic of IR smoke under entironment to vacuum and micro-gravitation,based maths-model of thermodynamic onflow pervasion by smoke formed, the experiment proves that the movement speed of smoke gradually minishes along with hoist of vacuum.The process after smoke formed analysed ,which proves that its movement rule relates hilum of particle.

本文对真空和微重力环境下的红外烟幕进行了动力学特性研究，建立了烟幕形成过程中的热力湍流扩散数学模型，通过实验表明随著真空度的升高，烟幕的运动速度逐渐减小；并对烟幕形成后的过程进行了分析，结果表明其运动规律跟粒子的粒径有关。

By using the analogy of star formation in open clusters in NGC 1313 we can infer that stars formed in a similar manner in the Milky Way and so can help us better understand the way the Sun was formed.

通过类比棒状星系NGC 1313中疏散星团的情况，我们可以推测出银河系恒星的类似形成过程，并且能让我们更好地理解太阳的形成。

Furthermore, we believe that the general rules for understanding the superstructures formed within boundary areas are correlated directly with different overlapping or connecting operation with respect to building units of flattened hexagons and P-B polygons. These rules are as following:I The adjoined domains at least have their basic structural units a side-shared (that is, sharing two column clustersП) The basic structural units in both domains have overlapping area as large as possible.3 For theξ-Al-Ni-Rh phase formed in the as-cast Al75Ni15Rh10 alloy, phase transition processes induced by electron beam irradiation with different amount of dose were studied by in-situ observations in an electron microscope.
