白噪声源与模拟计算机配合使用，是分析复杂地震动作用下结构和确定产生变形概率的方便方法。建议用“白色”地面加速度表示“标准大地震”，其谱密度为0.75 ftU ~ 2 N/secU ~ 4 N/cps，持续时间为1/2 min。
White-noise source used in conjunction with analog computer is convenient method of analyzing structures subjected to complex ground motions and of assigning probabilities to deformations arising; it is suggested that "standard large earthquake" be represented by "white" ground accelerations having flat spectral density of 0.75 ftU2N/secU4N/cps and duration of 1/2 min.
