beyond a reasonable doubt指“排除合理怀疑”，排除合理怀疑是英美法系国家一致公认的刑事诉讼证明标准，所谓“排除合理怀疑”，首先意味着检控方对被告人有罪的证明并不需要达到排除“一切怀疑”的程度，它所要求的只是排除“合理的怀疑”。这并不是从正面对证明被告人有罪的标准所作的解释。如果从正面解释的话，这一标准可以变为“内心确信的证明”。但这已经不再是“排除合理怀疑”的本意。

 “合理的怀疑”。它主要有四层涵义：1.合理怀疑是有根据的怀疑，而不是无根据的怀疑，怀疑者本人能清楚地说明怀疑的根据是什么。2.排除合理怀疑的证明并不排除所有的可能性，而是排除那种没有根据的可能性。3.排除合理怀疑的证明要求法官对指控的犯罪事实形成内心确信，深信不疑。4.在存在合理怀疑时，法官应当作出有利于被告人的认定结论。

为了更好的理解该词，以下是其英文释义：Beyond a reasonable doubt is a legal standard of proof required to validate a criminal conviction in most adversarial legal systems. It is a higher standard of proof than the balance of probabilities (commonly used in civil matters) and is usually therefore reserved for criminal matters where what is at stake (e.g. someone's liberty) is considered more serious and therefore deserving of a higher threshold.
