 note = {Glass beads have often used to simulate the planetary regolith. Effective thermal conductivity has been measured for spherical glass beads in several diameters. There are some data which were obtained at low air pressures (about 1 Pa) to evaluate heat transfer rates through the contact regions of adjacent solid particles, and at pressure from 1 to 10(exp 5) Pa, to ascertain the effects of free molecule conduction. Geometrical considerations were used to develop equations for predicting the effect of pressure on effective conductivity. Masamune and Smith (1963), which involve only one arbitrary constant, agreed well with available data. However their theory cannot predict the thermal conductivity of the other data in the ambient pressure (approximately 10(exp 5) Pa). Nakagawa (1995) modified this theory by introducing a new parameter to describe the gas effect around the contact points between the particles. We could show that this modified model is possible to be applied to the all of experimental data of the powdered materials not only spherical glass beads but also lunar simulant or another sand materials., 資料番号: AA0063350017},
