由于MgO衬底的存在，bcc固体/sup 3/He从液相连续成核被检测到。对于超流体/sup 4/He，没有证据表明hcp或bcc固体从衬底连续成核。实验对比了正方形MgO晶格与三角形石墨基底晶格的影响。讨论了固体/sup 3/He体系的孔凝聚现象。
The continuous nucleation of bcc solid /sup 3/He from the liquid phase due to the presence of a MgO substrate is detected. for superfluid /sup 4/He there is no evidence of continuous nucleation of either the hcp or the bcc solid from the substrate. The experiment contrasts the influence of the square lattice of MgO with the triangular lattice of a basal-plane graphite substrate. The phenomenon of pore condensation for solid /sup 3/He is discussed.
