Universal Equipment for Borehole Ultrasonic Surveysontinuous logs, which permit a detailed study of the variation in velocity of longitudinal waves about a well bore; and b) full wave-form logging, which allows the determination not only of the velocity of longitudinal waves but also of that of transverse waves, and of the attenuation constants α. and α..止痛药 发表于 2025-3-29 06:04:01
Spectral Analysis for Recognition of Wave Formsion is also made in this presentation. Earlier approaches are generalized in this development by restricting neither the number of interfering waves nor the ratios between their delay times. It is assumed only that the number of interfering waves is finite.摆动 发表于 2025-3-29 10:05:21
Shear Waves Reflected from a Thin High-Speed Layeren paid to the PS wave reflected from the boundary at 280-m depth (t.), inasmuch as quite good data were obtained for it. We have studied the PS wave from the layer at 1350-m depth (t.) to a lesser extent.健谈的人 发表于 2025-3-29 12:24:47
