change can be divided into three phases through fatigue process. It has response relation between resistivity and interior structure. The change of resistivity is inversely proportional to unit volume carrier concentration. The mechanism of self-monitoring is caused by the change of the number of electronic carriers. Key words: asphalt concrete; self-monitoring; indirect tensile test; resistivity......
Synergistic action of non-solvent induced phase separation in preparation of poly(vinyl butyral) hollow fiber membrane via thermally induced phase separationQiu Yun-ren(邱运仁), Qi Jing(漆静), Wei Yu-qing...(vinyl butyral) hollow fiber membrane via thermally induced phase separation (TIPS) has been carried out. The results show that the hollow fiber membrane prepared at air gap zero has no skin layer......
