The Research Progress of Stab-Resistant Material
Advanced Materials Research, 2011Co-Authors: Da Wei, Rui Wang, Shu Jie ZhangAbstract:The text summarizes raw Material, manufacture method, stab-Resistant mechanism, stab-Resistant effect and the problem of the hard stab-Resistant clothing, semi-soft Stab-Resistant clothing and soft stab-proof clothing, and evaluates the advantages and disadvantages of various stab-Resistant clothing. Base on the analysis of the development course and status of stab-Resistant clothing, it explores and discusses the developing trend and research emphases of the stab-Resistant clothing according to requirements of the industrialization of the stab-Resistant Materials. This paper also put forward the suggestions and ideas about manufacture stab-proof textiles by composed yarn technique.

small ring testing of a creep Resistant Material
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2013Co-Authors: Christophe J Hyde, T H Hyde, Steve Nardone, E De BruyckeAbstract:Many components in conventional and nuclear power plant, aero-engines, chemical plant etc., operate at temperatures which are high enough for creep to occur. These include steam pipes, pipe branches, gas and steam turbine blades, etc. The manufacture of such components may also require welds to be part of them. In most cases, only nominal operating conditions (i.e. pressure, temperatures, system load, etc.) are known and hence precise life predictions for these components are not possible. Also, the proportion of life consumed will vary from position to position within a component. Hence, non-destructive techniques are adopted to assist in making decisions on whether to repair, continue operating or replace certain components. One such approach is to test a small sample removed from the component to make small creep test specimens which can be tested to give information on the remaining creep life of the component. When such a small sample cannot be removed from the operating component, e.g. in the case of small components, the component can be taken out of operation in order to make small creep test specimens, the results from which can then be used to assist with making decisions regarding similar or future components. This paper presents a small creep test specimen which can be used for the testing of particularly strong and creep Resistant Materials, such as nickel-based superalloys.

Genetic Transformation of Sweet Potato and Progress in Antiviral Transgenic Sweet Potato
Journal of Henan Agricultural Sciences, 2011Co-Authors: Zhang ZhenchenAbstract:Virus disease is a severe constraint in sweet potato production.Traditional breeding for disease resistance can not meet the requirement of production,due to lack of Resistant Material and demand for long breeding cycle.The development of transgenic technology provides a new way for breeding of antiviral sweet potato.This paper reviews recent research progress of genetic transformation and antiviral gene engineering of sweet potato.
