它表明，空间为基础的引力波探测器，如DECIGO和/或大爆炸观测器将为我们提供宝贵的信息，宇宙膨胀后的热历史，他们将能够确定再热温度T{sub R}，只要它位于宇宙学引力子问题，T{sub R}{approx}10{sup 5-9} GeV的范围内。因此，强烈希望这些建议尽快付诸实施。
It is shown that space-based gravitational-wave detectors such as DECIGO and/or the Big Bang Observer will provide us with invaluable information on the cosmic thermal history after inflation, and they will be able to determine the reheat temperature T{sub R} provided that it lies in the range preferred by the cosmological gravitino problem, T{sub R}{approx}10{sup 5-9} GeV. Therefore it is strongly desired that they will be put into practice as soon as possible.
