Nrs was strongly related to site conditions and depth , while the bnrs had better consistency among all strong motion records than the conventional nrs under the influence of site condition , depth and motion component
而不同场地不同深度不同分量方向的双规准反应谱之间差别甚小，双规准反应谱比规准反应谱表现出良好的一致性。
The long period attenuation relationship of acceleration response spectrum is developed using this database . the short - period attenuation equation is developed by using the analog strong motion records of western north america . by connecting the short period and the long period attenuation relationships together , the wide period ( 7 " = 0 . 04 - 20sec ) attenuation relationships for horizontal acceleration response spectrum of western north america are obtained
与用模拟式强震仪记录所得出的美国西部地区短周期( t = 0 . 04s - 4s )加速度反应谱衰减关系结合，得出了美国西部地区水平向基岩宽周期( t = 0 . 04 - 20s )加速度反应谱衰减关系。
