This paper introduces the design requirement and calculation of the important components of circular knitting machine such as cam, needle, and so on, by means of the relations between the knitting unit and the knitting technology.

As a crucial component of the machine,the design- ing and calculating way of the cam's parameters,such as incline angle,height and minimum width is researched from the viewpoint of mechanics.

Index extension of the triangular inequality;

Based on the region growing algorithm of triangular,the paper manages the information of the point,edge and face of triangular mesh by list,and paints the Delaunay triangular mesh using the double-buffer technology of OpenGL language.

This article has dealt vrith the relationships between complex number and triangle,geometry,inequality and binomial and their applications in related exercises.

Objective To observe the cavernous sinus via orbital and pars zygomatica approach in frontal and temple region,we can obtain the microanatomical data of the bouncary,area,content and relationship about important structure of the commonly used triangle in cavernous sinus in order to offer microanatomical reference for operation in cavernous sinus.

Perspective to the Textile and Clothing Industry in the Yangtze River Delta: from Comparison Superiority to Competitive Advantage;

Research on International Competitiveness of Shipbuilding Industy in the Yangtze River Delta;

On Development Mode and Strategy of Shipbuilding Industrial Cluster in Yangtze River Delta;

For solving the problems of conventional low twist yarns due to their low tenacity,a specially designed false twister was installed between the front rollers and yarn guide on a conventional ring spinning frame for increasing fiber migration and entanglement in the spinning triangle,leading to a reinforcement of yarn strength.
