1.引言石墨化过程中针状焦的不可逆体积膨胀,即所谓的气胀,一般认为其特点在于焦中孔隙率的发展,有人报道焦炭的结构是气胀的重要因素之一,以往通过比较针状焦和普通焦样品不同的热膨胀系数来讨论焦炭结构的影响,对焦炭结构的观测是在不考虑焦织构流线方向的情况下进行的。本文的目的是评价各种针状焦晶气孔的大小,弄清焦炭的结构性能对气胀的影响。

the purpose of this research was to assess money spent and calories consumed by college students from fast food restaurants located on and around a southern college campus. A convenience sample (n = 152) of undergraduate college students (aged 18 - 24) at a southern university participated in a survey that measured dietary intake from seven local fast food chains using a researcher developed food frequency questionnaire and a lifestyle behavior survey that collected data on health practices. A strong positive correlation was found between total monthly fast food expense and total monthly fast food caloric consumption (r(150) = 0.94, p t test comparing the mean monthly fast food restaurant expense males to females found a significant difference between the two groups (t(150) = 4.19, p the more money spent by college students contributed to a higher amount of calories consumed from fast food in a typical month. Future research needs to determine if college students are contributing to the high obesity rate and if limiting fast food restaurants on and around college campuses would help decrease fast food consumption in college students.
