摘　　要：在设计填空题答案的过程中,存在着试题答案不完整的问题,这会影响到考试的信度。正则表达式是一种描述字符串结构模式的形式化表达方法,在字符串处理上有着强大的功能。利用正则表达式,可以判断一个字符序列(答题结果)是否与一个模式(试题答案)相匹配。在填空题试题答案设计和计算机自动评分过程中,运用正则表达式实现填空题的计算机自动评分,取得了理想的结果。In the process of designing the answer to fill in the blank, there is a problem that the answer is not complete, and it may affect the reliabihty of the test. The regular expression, which is a formal expression method to describe the structure of the string pattern, has a strong function in string processing. The regular expression can be used to determine a sequence of characters （that is, the results of the candidates answer） and a pattern （that is, the answer to the question） to match. In the design of the answer to fill in the blank and the computer automatic marking, the regular expression is used to realize the automatic marking of the filling problem, and has achieved the desired results.
