Theoretical deduction says that in a borehole penetrating elastic formations, pseudo Rayleigh wave does not take shear-wave velocity, but its group velocity may be very close to shear-wave velocity.
推演说明在弹性地层的井眼中，伪瑞利波不可能以横波速度传播，但其群速度与横波速度可以非常接近。
If sampling length doesn't adapt rotative velocity, the results of calculation by FFT or periodogram analysis will lead to pseudo-periods, which distorts the principal value function terms.
若采样长度与回转速度不吻合，将会出现伪周期，使主值函数项中提取周期成分后的信号失实。
It is found that the input energy and momentary input energy spectra with a damping factor of 5% can be estimated from the pseudo-velocity spectra with damping factors of 0.5% and 10%.
研究发现，阻尼比为5%时的地震动总输入能量谱和最大瞬时输入能量谱的等价速度谱可以分别用阻尼比为0.5%和10%下的拟速度谱来近似获得；
