摘　　要：当无验前信息可用时,本文导出了再入飞行器最大飞行距离的似然比检验统计量,由此构造出的置信区间优于由非中心t分布构造的对称截尾置信区间.最后,对两个常用的最大飞行距离的概率水平.0.95和0.99.以及对不同的子样数和置信水平,列出了构造这种似然比置信区间所需要的常系数,c_1和c_2的取值表.When no prior information is available, the likelihood ratio statistics for testing the maximum range of a reentrant vehicle are derived. The confidence intervals based on these statistics are better than the confidence interval obtained by symmetrically trimming the tails of some non-central t-distributions. Finally, for two commonly used probability levels of the maximum range, 0.95 and, 0.99, various sample sizes and confidence levels, constant coefficients, c1 and c2, which will be used in constructing this kind of likelihood ratio confidence intervals, are tabled.
