The main results are:(1) The cumulate cause-effects model was demonstrated at both macro and micro level data. The problem of data fitting of hypertension prevalence data was solved well enough with the cumulate cause-effects model. The parameters of the model were meaningful for the practice.(2) Taking the hypertension developing speed as an indicator of health equality of hypertension between urban and rural residents in China and discovered the macro level determinants of it.(3) The causal network was testified by the structure equation model.(4) It is found that the major determinants of hypertension prevalence in China is population ageing, overweight, lifestyle changing due to high economic developing speed and the lagging behind of health education.
主要的研究成果有:(1)首次观测到我国高血压的患病率曲线符合累积风险效应模型,解决了高血压患病率资料数据拟合中长期存在的方法学问题,并对模型中参数的实际流行病学意义给出了合理的解释,能够对疾病的发病率进行间接的估计;(2)提出了用高血压的发展速度作为衡量我国城乡高血压造成的健康不平等的重要指标,解决了我国高血压患病率评价中长期存在的一些错误性认识,揭示了我国高血压城乡发展不平衡的宏观决定因素;(3)利用结构方程模型对构建的网络模型进行拟合分析,证明了模型的有效性;(4)揭示了目前影响我国高血压发展趋势的决定因素,主要包括人口老龄化趋势加剧、超重人口比例增加、经济的快速发展带来生活方式的转变和健康教育的相对滞后等几个方面。

The design is key slot, shaft coupling, gear and bearings for the design parameters of the design process, the application of the Access database, inlay in Auto cad 2004 and the Auto lisp VBA procedures, the main design concepts : using VBA common structure for the selection and design, Access databases and enquiries generated through relevant parameters instead seek out a large amount of information generated readable final text documents (including the document mapping the relevant data used), and then using Auto lisp procedures required readable text documents commonly used in the design of the structure direct mapping.
谁能帮忙翻译一下!谢了!!本设计是对键槽、联轴器、齿轮和轴承进行参数化设计,设计过程中,应用了Access数据库、嵌于Auto CAD 2004的VBA和Auto LISP程序,主要设计思想是:利用VBA对常用结构进行选择和设计,并通过查询Access数据库生成相关参数,而不用再去查找大量资料,最后生成可读文本文件(文件中包括绘图用到的相关数据),然后利用Auto LISP程序调用可读文本文件对设计的常用结构直接进行绘图。
