摘要：
An axial heat flow, steady state method for thermal conductivity measurements above 80 K on poor conductors is described. A split shield (one part held at the sink temperature and the other kept at the hot-end temperature) is shown to be successful for the correction of radiation errors. Measurements on poly(methyl methacrylate) (PMMA) are reported.
