摘　　要：分析软件故障暴露率与软件测试次数之间的关系,提出在保证可靠性测试结果客观准确的前提下,有效减少验证测试次数的方法。结合软件可靠性和体系结构相关理论,提出基于组件的软件失效率定量计算方法。研究并利用软件可靠性度量方法,提高了软件可靠性测试效率和可靠性评估准确性。This paper analyzes the relationship between the rate of software fault exposure and software testing times. On the premise of objective and accurate results of reliability testing, several methods of how to reduce the total number of testing times are proposed. Based on the theory of software reliability and software architecture, a quantitative computation method of component-based software failure rate is presented. The efficiency of software reliability testing and the accuracy of reliability estimation are improved by the research of software reliability measurement.
