1990-1992年广西5种主要死因年龄死亡的数学模型研究

Study on mathematical mode for 5 death causes of age - specific death rate in Guangxi, 1990 - 1992.

利用指数曲线模型Ｙ＝ｄｅ^（ｂｘ）模拟了脑血管病、气管炎肺气肿哮喘、恶性肿瘤、心脏病、肺结核５种死因在广西人群中的理论年龄死亡模型，模型均具有较好的拟合度。讨论并分析了５种模型的变化趋势及５种死因对人群年龄死亡模型的影响作用。

ln this paper , exponential model Y = de￣(bx) is used to simulate theoretically the age - spe- cific death rate for cerebrovascular disease , em- physematous asthma, malignant tumor, cardiopa- thy, tuberculosis of lungs in population of Guangxi , The mathematical model exhibits a good fitness. The changing trend of 5 models and the effect of 5 death causes on age - specific death rate model are also discussed and analysed .
