摘要：

The water content in a rock material can significantly change the thermal neutron diffusion parameters with respect to those of the dry medium. The effect has been studied for dolomite, CaMg(CO3)(2), by Monte Carlo simulations of the variable buckling experiments for 10 series of samples. The density-removed diffusion cooling coefficient C-M varies hyperbolically by two orders of magnitude with water content in the range of 0-20%. (C) 2004 Elsevier Ltd. All rights reserved.
