在分析对外汉语专业建设的现状及普遍的缺陷的立足点之上,提出适合我院对外汉语专业建设发展的几点意见和构想。从课程设置、实践教学、就业问题及师资建设方面进行改革探讨,使对外汉语专业建设更有特色。     

Wet Permeability and Moisture Vapor Transmission Characteristics of Soybean Knitted Fabrics

Wet permeability of fibrous assembly is mainly influenced by the properties of liquid and the configurations of the fiber which consist of diameter of fiber, twist angle and fiber alignment in a yarn. It can be seen from experimental results that the knitted fabric made of soybean (SB) fiber has good properties both in wet permeability and vapor transmission so that the knitting technology and fabric characteristics can be improved.

Study on Wet Permeability Models of Yarns and Knitted Fabrics

Water transport through the pore structure of the knitted fabric can occur only in place where the fiber-water surface attraction force is greater than the water weight in the capillary. To investigate wet permeability of the knitted yarn in the fabric, a liquid transport model is established. The main factors which have significant influences on the liquid transport have been analyzed. It is derived from the argument that the optimal design for the knitted fabric with quick sweat transport property can be obtained.

The antipole evolution effect of immature-low mature organic matter

The low-temperature and low-pressure artificial hydropyrolysis experiment proves that at the immature-low mature thermal evolution stage of source rock, the condensation reaction and the thermal degradation reaction occur continuously and simultaneously in both soluble organic matter and insoluble organic matter. This process was called “antipole evolution”, which means transformation into two opposing extremes. The soluble organic matter and insoluble organic matter constitute an organic related integrity, transforming mutually in a dynamic equilibrium. Non-hydrocarbon and asphaltene are key intermediates between kerogen and hydrocarbon. Asphaltene is one of the major sources of immature hydrocarbons.
