摘要
目的介绍谱分析方法的原理,探索应用谱分析方法对医院患者住院时间规律进行分析。方法介绍谱分析方法的原理和计算步骤,并以伤害住院儿童为例,应用谱分析方法对医院信息系统中的患者住院时间序列资料进行分析。结果医院住院患者时间序列在频域范围内进行分析,儿童伤害住院人次数的时间规律呈现以6个月为周期的波动。结论利用谱分析能准确地提取周期信息,这对于时间序列数据的进一步处理有着重要的意义。
Objective To introduce the principles of spectral analysis methods and explore the application of spectral analysis methods for the analysis of hospital patients' hospitalized time. Methods Spectral analysis of the principles and methods of calculation steps was introduced, and children hospitalized with injuries were selected. By spectral analysis methods patients hospitalized time series data were analysed. Results Hospital time series in the context of frequency domain analysis, the number of people hospitalized children hurt in a time of six months for the cycle fluctuations, Conclusion Using spectral analysis, information cycle was accurately extracted. It was very important for the further processing of time series data.
