There were no significant difference between diabetics in hospital and diabetics who had participated diabetes education in gender,age,marital status,occupation, education level and the form of medical expenses.It is suggested that the two groups come from the same patients. 2.According to the result of content validity and retest reliability,questionnaire of compliance has a good validity and reliability.According to the result of consistence test,collection validity,discrimination validity and construct validity,SF-36 has a good validity and reliability.3.We used self paired comparison to analyze the data of the treatment compliance from the patients who had participated diabetes education and the patients in hospital who hadn\'t participated diabetic education.The results suggest that the treatment compliance of patients is improved as the number of times that these patients participated diabetes education was increased.The treatment compliance of the patients in hospital is improved just in a short-term period,who hadn\'t participated diabetes education.

研究结果1、住院糖尿病患者与参加健康教育的糖尿病患者在性别、年龄、婚姻、职业、文化程度、医疗用度承担形式上均无统计学差异，说明两组人群来自同一整体。2、根据内容效度和重测信度的结果证实允从性问卷具有良好的信度和效度；根据内部一致性检验、集合效度、区分效度和结构效度的结果证实SF-36量表具有良好的信度和效度。3、对参与健康教育的糖尿病患者进行的允从性跟踪调查结果进行自身配对前后比较，并与未参加健康教育的住院糖尿病患者的允从性得分进行比较，发现糖尿病患者治疗允从性随着参加健康教育次数的增多而进步；未参加教育的住院患者治疗允从性在进院和刚出院的短期内有一定进步，但随后逐渐下降至进院前水平。

A new cyclic constitutive model for sands which can describe the deformation behavior of sands under combined variation of principal stress axes and magnitudes was developed based on the above physical fundamentals. And its effectiveness under the complex stress paths including cyclic rotation of principal stress axes is verified by a good comparison of model simulation with test results for sands.
