吸烟过程数学模型定性分析-毕业论文.docxVIP

北京信息科技大学毕业设计（论文）题目：吸烟过程的数学模型定性分析学院：理学院专业：信息与计算科学学生姓名：袁铁明班级/学号信计1201/2012012535指导老师/督导老师：左军起止时间：200年月日至200 年月日摘要目前，世界上的吸烟人数众多，而中国亦是受吸烟问题困扰的重灾区之一。我国的吸烟人约在3亿，而约有7.4亿不吸烟者正在遭受二手烟的危害，每年因吸烟死亡的人数逾百万，所以控烟形势刻不容缓。本文通过数学模型的建立，研究人们在吸烟过程中有害物质传播的途径及其传播的相关因素。在原有的基础上，研究这些相关因素的内外相关性。由此建立数学模型定性分析人体吸入毒物量与哪些因素有关，并进行数学模型的分析。本文一共分为四个章节：查阅资料，论述一下课题研究的背景及重要意义。包括中国及其它国家吸烟人口规模，控烟现状分析，采取控烟措施的重要性。查阅资料详细分析烟草的有害成分，哪些疾病与吸烟有关，吸烟对健康导致的各种危害，亟待解决的问题有哪些以及国外控烟采取的一些有效措施，目前我国控烟采取的措施，取得的效果等。在已有的研究基础上，提出吸烟过程的数学模型建立，分析人体吸入毒物量与哪些因素有关，以及他们的数量表达式。其中定性分析吸烟过程的危害，建立数学模型细致分析，得出有效结论和建议。总结本文的主要结论，告示人们控烟过程任务艰巨，需进一步提高人们对吸烟有害健康的认识。通过本文，说明了仅仅靠一些吸烟过程的预防措施来减少吸烟的危害是有限的，最后还要告知人们，吸烟有害健康。关键词：吸烟传播控烟成果定型分析AbstractAt present, there are a lot of people in the world，the China is also one of the hardest hit by the problem of smoking. The smokers in our country are about 300 million, about 740 million non-smokers are suffering from secondhand smoke, the annual number of deaths due to smoking of more than one million, so the tobacco control situation urgent.In the first chapter, we have access to information and discuss the background and significance of the research topic. Including the size of smoking in China and other countries, analysis of the current situation of tobacco control, take the importance of tobacco control measures.In the second chapter,we should access to information to analyze the harmful components of tobacco, what are the diseases associated with smoking and all the health hazards of smoking causes. There are some problems to be solved and the effective measures which take the foreign tobacco control, at present, Chinas tobacco control measures, achieved results etc.. In the third chapter, based on the existing research, the mathematical model of smoking process is established , analysis of inhaled poison quantity and what factors, and their quantitative expressions. The qualitative analysis of the harm of smoking, to establish the mathematical model of detailed analysis, draw valid conclusions and recommenda
