摘要
为了解决过低估计测验的信度问题．本文探讨了几个计算测验信度的方法，讨论了不同场合下信度公式的合理使用，并对所有方法提供了充分的理论依据．
For solving the questions of underestimating the test reliability,some methods ofcalcuating the test reliability were approached,reasonable uses of reliability formulas indifferent situation were discussed,and full theory Basis of all methods was provided inthis paper.
