纤维和纱线断裂机理及属性指标再认识

目前对纤维和纱线断裂饥理的阐述多是从受力角度考虑的，其属性指标习惯用断裂强力和断裂伸长率表示，而实验发现：同一纤维或纱线，在不同的拉伸条件下．得到的断裂强力、断裂伸长率并不是常数．进一步分析得出断裂功近似于常数．从而推出断裂功应是合理的属性指标．     

刀额新对虾脑部胶质细胞和神经鞘

本文用透射电镜观察了刀额新对虾（Ｍｅｔａｐｅｎａｅｕｓ　ｅｎｓｉｓ）脑部神经胶质细胞和神经纤维髓鞘；结果表明。这些胶质细胞呈圆形或椭圆形，直径约６４００ｎｍ。在胞质中，没有观察到有线粒体，高尔基体等细胞结构，细胞核大电子致密的异染色质位于核边缘且连成块状，髓鞘直径约６４００—９３００ｎｍ。鞘层厚约５００—６７０ｎｍ。在髓鞘层中存在着微管结构，微管直径约８３ｎｍ。     

On ratio estimators in two phase sampling under size stratification and estimation over two successive occasions

Adopting size stratification when the auxiliary character is approximated by a continuous uniform distribution, a double sampling ratio strategy has been suggested. this sampling strategy has been compared with some of the known sampling strategies. the applicability of this strategy to sampling on two successive occasions has also been investigated     

Algebraic foundation of mathematical statistics 2

In the paper fibre processes are considered, i.e. discrete sets of curves distributed at random in the plane. For translation invariant fibre processes the PALM distribution of the angle in a typical fibre point is defined, and point processes are studied which are obtained by intersection with lines. As a special case motion invariant, i.e. translation invariant and isotropic, fibre processes are treated. Finally weighted fibre processes are considered. As example segment processes are investigated.
