摘要翻译：
计算机模拟表明，超过22个分子的超流{It对}-氢团簇可以通过用较重的{It邻}-氘同位素取代一两个分子而变成绝缘的“固体”。用取代的{邻位}-氢观察到的效应要小得多。取代的{It邻位}-氘分子通常位于团簇的内部，而{It邻位}-氢杂质主要位于外壳，靠近表面。讨论了纯{it对}氢团簇超流性的含义。

英文摘要：
It is shown by computer simulations that superfluid {\it para}-hydrogen clusters of more than 22 molecules can be turned insulating and "solidlike" by the replacement of as few as one or two molecules, with ones of the heavier {\it ortho}-deuterium isotope. A much smaller effect is observed with substitutional {\it ortho}-hydrogen. Substitutional {\it ortho}-deuterium molecules prevalently sit in the inner part of the cluster, whereas {\it ortho}-hydrogen impurities reside primarily in the outer shell, near the surface. Implications on the superfluidity of pure {\it para}-hydrogen clusters are discussed.
