Simple, effective and safe flame retardants are required to improve flame retardant properties of polymer ***, traditional additive flame retardants, such as halogen-flame retardants and intumescent flame retardants, are likely to cause phase separation of functional phases due to their poor dispersibility and compatibility, or are difficult to be suitable for the high temperature processing conditions of melt-spun fibers. Here, in an effort to develop a practical flame retardant system in which zinc diphosphinate（DEPZn） and D-glucose（DG）were selectively incorporated into polyethylene terephthalate（PET） fiber was developed. As a result, the dense nano-scale zinc phosphate microspheres were formed on the surface and inside the residual carbon during combustion. Thus, PET fibers were endowed with excellent flame retardancy through a thermal barrier and enhancement of physical strength for the carbon layer. Moreover, a synergistic flame-retardant effect was found between DEPZn and DG. DG reduced the size of the zinc phosphate nanosphere from 200 nm to 50 nm, making the carbon layer denser and smoother. As a result, the peak heat release of the resultant PET composite fiber decreased to 410 k W/m2compared 1276 k W/m2for neat PET fiber. Moreover, the total smoke release also dropped from 71 MJ/kg of neat PET fiber to 64 MJ/kg for PET composite fibers. These results provide a promising strategy for the production of industrialized PET flame retardant fibers.

作者： Xiao Xian the Institute of international Studies at the Yunnan University

Although China and Turkey established diplomatic relations in 1971, political, economic and cultural exchanges were few during the Cold War period. The geopolitical map of Central Asia and the Middle East changed dramatically after the end of the Cold War and bilateral relations between China and Turkey also improved rapidly. China and Turkey, two emerging powers, are now entering a new stage of strategic cooperation. Meanwhile, several new problems have emerged. Thus there is considerable need to strengthen this strategic partnership which will require systematic effort from both sides.

作者：罗艳华 the School of international Studies Peking University

In China, there are many human rights organizations, because of their focuses and priorities related to human rights. China Society for Human Rights Studies(CSHRS) is the largest of them, which focuses on human rights research, popularizing and international exchanges. This paper takes CSHRS as an example to show the role of the human rights organizations play in China. From the practice of CSHRS, we can see the human rights organizations in China play a kind of constructive role through involving in very broad fields and engaging in the various activities of human rights protection. Their works include participating in drafting the National Human Rights Action Plans, giving constructive suggestions, working in human rights education, engaging in international exchanges and cooperation, taking part in the work of UPR, raising fund and implementing projects, and so on. They are trying hard to contribute to improve human rights situation in China.
