Comparison of Two Modes in Engineering Drawing Teaching: Traditional Teaching and Multimedia NetworkTeaching Y.Tao Engineering academy, South China Agricultural University, Guangzhou, 510030,P.R.China tylptc@21cn.com Key words: Engineering drawing, Traditional teaching, Multimedia network teaching Abstract: In order to explore good teaching methods, the traditional teaching model and online teaching mode were compared and their own characteristics were analyzed.
Engineering drawing is a skill required of the basic course for engineering students.
Now, Let us compare the two modes of teaching materials, teaching methods, assessment modes, effects and other aspects.
Comparison of the two teaching materials.From the physical and psychological points, two types of materials were analyzed.
The monotony of traditional color materials, generally "black and white", are easy to make students feel bored and tired.

A Study on Tribological Behavior of Engineering Ceramics – Representative Metals WANG Pengxiaoa , TIAN Xinlib, ZHANG Baoguoc, WANG Longd Science and Technology on Remanufacturing Laboratory, Academy of Armored Forces Engineering, Beijing, China, 100072 awangpx2008@126.com, tianxli719251@sohu.comb, czhang_baoguo@126.com, dwanglong201@126.com Keywords: Engineering ceramic; optimal friction pair; oil-less lubrication; friction and wear.
In order to obtain the optimal engineering ceramics- metals pair with the best tribological performance, the tribological orthogonal tests for engineering ceramics such as Si3N4, SiC, ZrO2 and representative metals such as 45steel, CCr15 bearing steel, tin bronze QSn4-3 and tin-based babbit ZChSnSb8-4 with oil-less lubrication were carried out by using UMT-3 wear machine and SEM.
Introduction Owing to the excellent properties such as low density, high hardness, superior chemistry stability and great temperature strength, Si3N4, SiC, ZrO2 and other engineering ceramic materials are increasingly being used for critical components in friction pairs [1, 2].
There were four factors in the orthogonal experiment such as: the material of the above ceramic sample (refer with Material #1), the material of the below metal sample (refer with Material #2), load, and relative velocity [7].

This special edition presents a collection of contemporary research and technological developments across several key areas of materials science and engineering.
The four chapters of this edition highlight both fundamental studies and innovative approaches that drive modern advancements in composites, metallic materials, catalysis for environmental engineering, and particle system behaviour.
The edition can serve as a valuable resource for researchers, engineers, and students seeking to deepen their understanding of materials development, their processing strategies, and the functional application.

It is crucial to choose the appropriate green building materials, because it acts as a key factor to the development of green building.
Until now, the building materials which have been certificated by ecolabel are only the hard floor materials (2002/272/CE) and indoor paints, varnishes materials (2002/739/CE)
(2) It has weak guidance to the materials manufacturers.

The PPC scaffolds may be useful in vascular tissue engineering if they were further modified chemically or with appropriate therapeutic molecules.
Generally, nature materials have better biocompatibility, and synthetic ones have better mechanical performance.
Experiment. 2.1 Materials Poly (propylene carbonate) (PPC) was purchased from Mengxi Hightech Co.
Like other synthetic materials, PPC fibers have good mechanical performance to support the scaffold.

During the recent years, there are some new optoelectronic materials which have been developed for using in apparel design, such as optical fiber, LED yarn, colored solar cell, etc. [1-5] The apparels using optoelectronic components have been an important issue for research.
Huang [11] used the theory of inventive problem solving (TRIZ) to design a kind of apparel with function of kinesiology, including material, style and tailoring.
However, these opportunities should be confirmed before implementation, i.e. the key design issues are needed to be verified the correctness.
In this study, the Delphi method was used for verification of key design themes.
