Due to the complexity of the structures, their modeling and simulation needs to be solved in three-dimensional (3D) CAD developments. In this paper, 3D loop geometrical models of weft knitted fancy structures, including tuck stitch, jacquard stitch, transfer stitch and fleecy stitch, were developed based on an improved model of plain loop, and their central axes as some 3D space curves were achieved by using Non-Uniform Rational B-Splines (NURBS). The 3D visual simulation programme was written in C++ programming language using OpenGL, which was a function library of 3D graphics. Some examples of weft knitted fancy fabrics were generated and practical application of 3D simulation was discussed.展开更多

The investigated complex structure fancy yams have a multithread structure composed of three components core, effect, and binder yams. In current research the precondition was accepted that the cross-sections of the both two yams of the effect intermediate product in the complex structure fancy yam remain the circles shaped, and this shape does not change during manufacturing of the fancy yam. Mathematical model of complex structure fancy yarn is established based on parameter equation of space helix line and computer simulative is further carried out using the computational mathematical tool Matlab 6.5. Theoretical structure of fancy yam is compared with an experimental sample. The simulative system would help for further the set of informative in designing of new assortment of the complex structure fancy yarns and prediction of visual effects of fancy yams in end-use fabrics.展开更多

Therefore, in view of its advantages, many higher vocational colleges in Hebei Province have offered this course. Its purpose is to enable students to have good physical quality under this training, but at the same time, the sport is difficult, and because of the limited quality of students at this stage, students often have great fear of the course, which leads to the ineffective implementation of roller skating. Based on this, this paper mainly takes Hebei higher vocational colleges as an example to analyze how to overcome the fear of flatland fancy roller skating.展开更多

The story revolves around a sack of gold that every one of the 19 principal citizens in the"most honest and upright town"Hadleyburg desires to claim by any means, fair or foul. The vivid description reveals the bourgeois hypocrisy of the capitalist society. This article intends to study the story from the perspective of binary opposition and finds out three pairs of opposition, they are honesty vs. hypocrisy; trust vs. trap; fancy vs. fact, which makes the story more sarcastic and full of sight and wisdom.展开更多
