参考地区 meaning in Chinese

reference locality

The empirical attenuation relationship for horizontal acceleration response spectrum in reference region is developed by regression , and the relationships for eastern china and western china are obtained by transform method and the data from china . the western north america is set as the reference region
在方法上，采用了经验统计方法回归参考地区的反应谱衰减关系，用转换方法并加入中国数字地震台网记录得到中国东部地区和西部地区的反应谱衰减关系。
754 horizontal - component digital broad - band records in western north america are processed . the acceleration response spectra are calculated and used as part of the database . the response spectrum values are estimated by the earthquake magnitude definition and are used as another part of the database
将美国西部地区作为参考地区，对美国南加州地区的数字宽频带记录进行了搜集与处理后作为观测资料，共754条水平向记录，与利用震级定义所估计的反应谱值一起，用统计回归的方法建立美国西部长周期加速度反应谱衰减关系。
