Based on fuzzy characteristics in durability failure criterion of concrete structures durable life was estimated , in which process survival analysis method was considered with fuzzy theory and the contribution of statement of truncation data was taken into account 结合混凝土结构在耐久性评价中包含许多模糊性因素的特点，将模糊数学的思想融入到生存分析法中。基于结构的耐久性失效准则，并考虑删失数据的状态对混凝土结构耐久寿命的贡献，对混凝土结构的耐久寿命进行了统计分析。
Methods by defining defaulting as a failure event and time from treatment starting to defaulting as survival time , we applied survival analysis technique with a real data to estimate a so called adherent rate and a median adherent time for evaluation of treatment adherence for patients with tuberculosis 方法将退出疗程作为所关心的结局事件，将从登记治疗开始到退出疗程的时间作为坚持治疗时间，利用生存分析统计技术估计坚持治疗率和中位坚持治疗时间以评价结核病患者的治疗依从性。
