Especially establishing reserves in key universities is the key step of new mode, which is the primary mode of sports team at high level in ordinary universities. To research the situation of key sports team construction at high level, from the degree of competitive sports sustainable development, we research and analyze the cultivation mode of Chinese sports talents and influence factors, aiming at building a talents cultivation mode suitable for Chinese professional competitive sports development and exploring the sustainable way for athletes sports in theory.展开更多

In this work,four IPCs were investigated by atomic force microscopy-infrared(AFM-IR) to assess the phase compositions in situ, based on which in conjunction with the chain microstructure information obtained ex situ the distributions of the copolymer components were derived for each alloy. For the IPCs whose EbP comprises long P and long E segments, the EbP fraction was found to phase separate from the rubber and the PP matrix to form the cores of the disperse particles with the E-P segmented copolymer(EsP). In contrast, in the IPC with EbP composed of long P and short E segments, the EbP fraction formed an outer shell for the rubber particles with the cores comprising the EsP alone, and this IPC, containing a lower E comonomer content than its counterpart, exhibited both better impact resistance and higher flexural modulus. These results clarify how the chain structure of EbP governs the phase morphology in IPC, which in turn impacts the properties of the composite material.展开更多
