A new modified theoretical model is advanced in this paper. The equivalent diameter of the pore of a fibre web is used to calculate the valid opening size instead of the maximum diameter of inscribed circle used, because the fibres in practical fibre webs are flexible elastomers with definite diameters and the pore of fibre web may produce deformation in screening teat and engineering usage. The results show that the theoretical calculations coincide well with the engineering measurements. This method offers a theoretical basis for computer simulation to the performance of filters of heatbonded nonwoven fabrics.展开更多
目的探讨基于跨理论模型的动机性访谈对老年2型糖尿病患者血糖及自我管理行为的影响。方法选取2014年1月—2015年3月在中南大学湘雅三医院老年科住院治疗的2型糖尿病患者162例,采用随机数字表法将患者分为试验组(80例)和对照组(82例)。...目的探讨基于跨理论模型的动机性访谈对老年2型糖尿病患者血糖及自我管理行为的影响。方法选取2014年1月—2015年3月在中南大学湘雅三医院老年科住院治疗的2型糖尿病患者162例,采用随机数字表法将患者分为试验组(80例)和对照组(82例)。对照组患者入院后采用常规护理和健康教育进行干预,试验组患者在常规护理和健康教育基础上采用基于跨理论模型的动机性访谈进行干预。干预前及干预后6个月,比较两组患者空腹血糖(FBG)、糖化血红蛋白(HbA_(1c))、餐后两小时血糖(2 h PBG)以及2型糖尿病自我管理行为量表评分(包含饮食控制、锻炼、遵医嘱服药、血糖监测、足部护理、高低血糖处理6个方面)。结果两组患者干预前FBG、2 h PBG、HbA_(1c)水平及干预后2 h PBG水平比较,差异无统计学意义(P>0.05);干预后试验组患者FBG、HbA_(1c)水平低于对照组(P<0.05)。干预前两组患者饮食控制、锻炼、遵医嘱服药、血糖监测、足部护理、高低血糖处理评分比较,差异无统计学意义(P>0.05);干预后试验组患者饮食控制、锻炼、遵医嘱服药、血糖监测、足部护理、高低血糖处理评分均高于对照组(P<0.05)。结论基于跨理论模型的动机性访谈能帮助老年2型糖尿病患者有效控制血糖,并改善其自我管理行为。展开更多
