【摘要】 本课题主要是通过调查方式研究气候因素对耳石症是否有显著影响,从而找到耳石症的病因。根据灰色关联计算得出舒适度与病例数的关联度r=0.7437属于强关联,通过类平均系统聚类分析对数据的特征提取,即病例数对应的天气特征提取,从而得出病例数与气象因素存在着明显的周期关系,在舒适度为[50, 70]即人体最佳舒适度范围内,病例数为一年当中最少,其他数值呈现出两极化,最后通过ARIMA模型,预测1年期的病例数,得出科学结论并给出合理的建议。更多还原

【Abstract】 This paper is to investigate whether climate factors have significant influence on otolithiasis, so as to find out the etiology of otolithiasis. Calculated based on grey correlation comfort and r = 0. 7437 belong to strong correlation of correlation between the number of cases, through the class average system clustering analysis of the data feature extraction, the number of cases corresponding weather feature extraction, thus it is concluded that the number of cases and meteorological factors exist obvious cycle relationship, in comfort as [ 50, 70 ] the best comfort within the scope of the human body, the number of cases for a year at least, other numerical presents the polarization, finally by ARIMA model, predict the number of cases of one-year, scientific conclusion and give reasonable Suggestions.更多还原
