摘　　要：虽然NASA相关标准和美国军标对最高预示环境的统计意义和用途进行了明确的规定,但是由于缺少足够的说明材料,很多技术内容不能被很好地理解,给实际应用带来了困难。文章结合实际应用经验,对最高预示环境的定义、统计意义、不确定性因素等进行理解和分析,最后根据分析结论,给出了最高预示环境量值确定的方法和过程,并利用实例进行说明。Although the statistical content and purpose of Maximum Expected Environment （MEE） is specified in the test criteria issued by NASA and USAF, it is difficult to apply in practices because many technical contents are not well understood for insufficient explanatory material. Based on practical experiences, the concept, statistical content and uncetainty of MEE are summarized and analyzed. Based on analytical conclusion, the method and process on MEE level prediction is given, and an example is given for description of the process, This research can give some referrence for the designers of spacecraft dynamic environment.
