In the last part, we adopt the uniform questionnaire to analyse the incidence, itiology and symptoms of the DVI.The 225 related cases of DVI were studied. We carried on the statistic methods and got the conclusion:(1)Obviously the incidence on the left lower limbs is more serious than that on the right lower limbs of DVI, because of the special feature in anatomy.(2)The varicose veins is not an absolutely necessary symbol of DVI,but only a common symbol.(3)The hard physical labour, standing for a long time or sedentariness everyday for many years, DVT and coldness,wounded or operated, family history are all closely related to DVI.

第三部分通过对225例临床病例的总结，对下肢深静脉瓣膜功能不全的发病情况、病因、症状表现进行了分析，经统计学处理，结论如下：左下肢深静脉的返流程度明显重于右下肢；下肢浅静脉曲张是下肢深静脉瓣膜功能不全的常见症状，而非必有症状；重体力劳动、久坐、久站、DVT、受凉、外伤或手术、家族史与下肢深静脉瓣膜功能不全的发生及程度轻重有密切关系；特别是久坐，其对下肢深静脉瓣膜的损伤不亚于久站和重体力劳动。

Four research results in the research are provided on the basis of wholly absorbed attention behavior performance including eyes-gazing, concentration as well as completion of orders, attention-testing performance, and multiple attention-testing performance. The collected materials are analyzed throughvisual analyze and Tryon's C statistic. The results of this research are as follows: 1. Attention-training maintains and give rise to samples' attention behavior. 2. Attention-training makes samples' attention-testing performance better. 3. Attention-training has generalization effects on samples' self-instruction and strategies for monitoring and behavior. 4. Attention-training has different effects on samples of different genders.

本研究以专心注意行为表现、自编注意力测验表现、多向度注意力测验表现及班级教师访谈问卷四项结果作为依据，所得的资料以目视分析法及C统计进行分析，所得研究结果如下：一、三位受试者之C统计值达显著(P1.65)，显示注意力训练对受试者的专心注意行为具有提升与维持效果；二、三位受试者在四项分测验中，有三项测验之C统计值达显著(P1.65)，显示注意力训练对受试者在注意力测验的注意力表现具有提升效果；三、由班级教师访谈问卷分析中得知注意力训练对受试者的自我指导、监控策略与行为具有迁移效果；四、由自编注意力测验结果分析显示，注意力训练对不同性别学生能显现不同的训练效果。
