项目摘要
For low-temperature vapor-deposition experiments, we havemodified the adiabatic calorimeter and x-ray diffractometer in our laboratory, andconstructed a precise vapor-deposition line. We have measured the heat capacities of glassycarbon tetrachloride, propene and propane which are the simplest of the glassy molecularsubstances whose heat capacities have been measured before. Clear excess heat capacitiesat low temperatures and glass transitions were observed in these samples. The inelasticneutron scattering experiments revealed that the excess heat capacity is due to the bosonpeak characteristic to amorphous solids. The x-ray diffraction measurements ofvapor-deposited glassy water, propanol, and 1-pentane have clarified the relation betweenthe annealing effect around the glass transition temperature and hydrogen-bond structure.
对于低温蒸气沉积实验,我们在实验室中介绍了绝热量热仪和X射线衍射仪,并结构了精确的蒸气沉积线。我们已经测量了四氯化物,丙烯和丙烷的热容量,这是以前已经测量过的热能力的玻璃分子润滑剂中最简单的。在这些样品中观察到了低温和玻璃转变的清除。无弹性内部散射实验表明,过量的热容量是由于无定形固体的孔孔造成的。蒸发沉积的玻璃水,丙醇和1-戊烷的X射线衍射测量已经阐明了围绕玻璃过渡温度和氢键结构的退火效应的关系。
