地下玻璃固化体中元素迁移模型研究

scending flows, existing in the crust widely, can act on the vitrification, which is disposed underground. A imitative model of ascending flows was used to study the behavior of elements transportation in the underground vitrification. The result of the experiment demonstrates that with the effect of ascending flows, the elements vitrified in vitrification can transfer out in the form of nano-scale particles and accumulate continuously in the adsorber above the vitrification. In addition, the transportation speed of these elements increases according to the difference in temperature increasing.
