Evaluating Aging Coefficient x in Age - adjusted Effective Modulus Method

1982~2000年间，河南省人口老化系数增长了1.27%，人口老龄化的速度明显加快、程度不断加深。

The speed of aging population accelerated obviously and faster than the national average level .

方法利用人口普查资料和卫生事业发展资料，计算老年人口系数和人口老化系数等，对河南省人口老龄化现状、特点进行分析。

Methods The situation of population aging in Henan Province was analyzed by using the census data and health service data .

采用这种方法对钟差，频率偏差和老化系数进行了计算仿真，同时对滤波前后的阿伦方差进行了比较。

Using this method , the time error , frequency deviation and aging is simulated . Mean while , the Allan variance after controlling is compared with Allan variance before controlling .

采用老化速率法、老化系数法、标准偏差与平均值的比值比较法、经验方程外推法等方法对6种建筑密封胶样品经热老化、氙灯老化试验后的试验数据进行处理，以研究其耐久性。

Data from six building sealant samples after heat ageing tests and xenon-arc light ageing tests by way of aging velocity , aging coefficient , ratio comparison of STDEV and Average , and extrapolation of experiential equation were processed to study its durability .
