分析了纤维布拉格光栅传感器（FBGS）埋入纺织复合材料中的可行性及有效性，结果表明FBGS埋入复合材料中不影响所测物体的应变场，在一定条件下，FBGS所测得的应变和温度能代表所测物体的应变和温度。

The crystallization behavior of polypropylene (PP) copolymer obtained by in situ reactor copolymerization with or without a nucleating agent and/or nano-CaCO3 particles was investigated both by thermal analysis and by polarized light microscopy. The Avrami model is successfully used to describe the crystallization kinetics of the studied copolymer. The results of the investigation show that a dramatic decrease of the half-time of crystallization t1/2, as well as a significant increase of the overall crystallization rate, are observed in the presence of the nucleatingagent. These effects are further promoted in the presence the nano-CaCO3 particles. The incorporation of the nucleating agent and nano-CaCO3 particles into PP copolymer remarkably improved the mechanical properties and heat distortion temperature.

It is first proposed that textile structures made of stainless steel (SS) fiber can be used to measure large strain under high temperature Four knitting structures are designed and applied as strain sensor In this paper, it is observed that the resistance of SS fiber fabric has a linear relationship with strain within a definite range Any change in fabric structure may cause changes of the linear range and sensitivity of the strain sensor The effect of the maximum strain of tensile cycle on the sensitivity has also been discussed Based on the experimental result, a strain sensor of SS fiber textile structure has been designed and tested The main mechanism of fabric sensing has been deduced to be the change of contact resistance between yarns during stretching. It is proved that this SS fabric can be used to monitor strain change in various technological areas

A modified equation for charge conservation in electrospinning is suggested, and a nonlinear relation between the electric current of charged jet and the solution flow rate is obtained.

在反应器原位分散共聚中加入成核剂和纳米碳酸钙制备了增强型聚丙烯共聚物。增强型共聚物的冲击强度、弯曲应力和热变形温度大幅提高，拉伸强度也有所增加。同时结晶峰温度显著升高，且半结晶时间明显减少。
