引力伴子必须足够轻，这样周围的引力伴子就不会产生太大的宇宙减速，或者足够重，这样几乎所有的引力伴子都会在氦合成之前衰变。第二种选择是允许超对称性破缺尺度高于模型相关的下限10/sup 11/至10/sup 16/ GeV。
The gravitino must be either light enough so that ambient gravitinos would not produce too large a cosmic deceleration, or heavy enough so that almost all gravitinos would have decayed before the time of helium synthesis. The second alternative is shown to allow supersymmetry breaking scales above a model-dependent lower bound of 10/sup 11/ to 10/sup 16/ GeV.
