记录$$^{4}hbox {He}$$的许多特性的测量
通过充满固体$$^{4}hbox {He}$$的电池的质量通量
在马萨诸塞州大学和其他地方进行的审查。发现质量通量是温度的普适函数，具有作为驱动化学势的函数的非线性行为，如对于Luttinger液体所预期的那样，并且通量可以在浓度依赖的温度下通过$^{3}hbox {He}$$的存在而熄灭。
.强有力的证据表明，磁通量是由存在于固体中的位错的核心携带的。与量子流体的历史和固体氦的相关早期工作有一些联系，也与超固体概念和He中质量通量的理论有一些联系。

Measurements that document a number of the characteristics of $$^{4}hbox {He}$$
mass flux through a cell filled with solid $$^{4}hbox {He}$$
carried out at the University of Massachusetts and elsewhere are reviewed. The mass flux is found to be a universal function of temperature, to have nonlinear behavior as a function of the driving chemical potential as might be expected for a Luttinger liquid and the flux can be extinguished at a concentration-dependent temperature by the presence of $$^{3}hbox {He}$$
. Strong evidence indicates that the flux is carried by the cores of dislocations present in the solid. Some contact with the history of quantum fluids and relevant early work in solid helium is made as is contact with theory related to the notion of a supersolid and mass flux in $$^{4}hbox {He}$$
