Second fiber was epoxidated by using epichlorohydriri as etherifying agent. Effects of reaction time and reaction temperature on degree of substitution and epoxy value of the modified fiber were studied. Tt was indicated that they increases with pro longing of reaction time or increment of reaction temperature under 70。C, The characteristic absorption peaks of epoxidated fibers were observed from TR spectrum, which showed a lot of hydroxy Is on the fiber surface were replaced by the methyl epoxy group of epichlorohydrin. The calculations based on XRT) photo showed the crystalliriity was reduced to 21 A0% with the increased gap between molecular chains of modified fiber. TGA analysis indicated that thermal stability of fibers decreased slightly after modification. Tt was concluded in this paper that the rate constant of epoxidation of second fiber was ordered by 0J 1，0,25，0.35 under reaction temperature of 60,70 and 80, respectively. Activation energy of fiber epoxidation was 48.14 kJ/moL. [ABSTRACT FROM AUTHOR]

In a traffic system with HOV lanes, considering two modes of driving alone and carpooling, we proposed three kinds of travel cost functions for potential commuters such as carpoolers in HOV lanes, driving alone users and carpoolers in general purpose lanes. Assume that all commuters will experience a random travel time with discrete distribution during their trip, this paper compared the commuters' equilibrium choices of travel mode and travel route under the framework of cumulative prospect theory and expected utility theory. In addition, the sensitivity analysis on the proportion of driving alone users, the individual preference such as the reference point were conducted. The resultant observations show that the individuals' risk preference and reference dependence definitely affect the commuters' choices on the travel mode and travel route. When the proportion of driving alone users exceeds a critical value, the carpooling users will be better than driving alone users since they have higher cumulative prospect value. However, this critical value will be slightly overestimated under the framework of expected utility theory. [ABSTRACT FROM AUTHOR]
