语源
  1. late Middle English: from Latin decimat- 'taken as a tenth', from the verb decimare, from decimus 'tenth'. In Middle English the term decimation denoted the levying of a tithe, and later the tax imposed by Cromwell on the Royalists (1655). The verb decimate originally alluded to the Roman punishment of executing one man in ten of a mutinous legion
