本文给出了Kr/石墨(石墨箔)体系中一层和两层之间热容的研究结果。对应于可公度-不可公度转变、可公度-流体转变和以前未观察到的不可公度-流体转变的热容异常界定了登记相的高覆盖范围。根据热容数据提出的相图表明了一种新类型多临界点的可能性。
The results of a heat-capacity study of the region between one and two layers in the Kr/graphite (Grafoil) system are presented. Heat-capacity anomalies corresponding to the commensurable-incommensurable transition, the commensurable-fluid transition, and a previously unobserved incommensurable-fluid transition delimit the high-coverage extent of the registered phase. A phase diagram proposed on the basis of the heat-capacity data suggests the possibility of a new type of multicritical point.
