该文研究了河南省不同年龄组的历史发展趋势和65岁以上人口未来发展趋势以及影响老龄化相关因素的问题。通过对不同时期的人口数据的分析和预测,从一个经典的模型入手,建立了三个不同的模型,分别 模型、 模型和关联分析模型,然后采用统计分析的方法来解决这些问题,预测出了河南省未来老龄化人口的发展。(This paper studies the different age groups in Henan Province of historical development trends and population over the age of 65, as well as the impact of future development trend of aging-related factors. Different stages of the analysis of population data and projections from a model of the classic, the establishment of three different models, namely, model, models and associated analysis model, and then using statistical analysis methods to solve these problems, predict the Henan Province, the future development of an aging population.)

dcbraking
DC dynamic braking is obtained when the stator of an induction motor running at a speed is connected to a dc supply.dc current flowing through the stator produces a stationary magnetic field.Motion of rotor in this field induces voltage in the rotor winding.Machine therefore works as a generator.Generated energy is dissipated in the rotor circuit resistance,thus giving dynamic braking.
