A time-varying mechanical perturbation will propagate as mechanical waves which in a solid body can be compressional waves or shear waves 在动态方法,时间变化的力量被应用于组织,它可能或者是短的瞬变机械力量或振动力量与fixed频率。 时间变化的机械扰动将繁殖作为在固体可以是压缩波或切变波的机械波浪 [...
A speaker unit has a plurality of sound sources each outputting a sound wave. The compressional, sound wave output from the speaker unit arrives, or vibrat... T Matsumoto - 《Journal of the Acoustical Society of America》 被引量: 3发表: 2010年 Cable Vibration- Methods of Measurement Test ...
The two compressional waves will interfere to produce a dipole shear wave in the earth surrounding the well. The dipole shear wave arrival is detected at two locations in the fluid spaced longitudinally along the well from each other and from the plate. The ratio of the time interval between ...
The present invention relates to a submarine signaling device and more particularly to a device for transmitting and receiving compressional waves under wa... 被引量: 0发表: 0年 A principal object of our invention is to provide new and improved apparatus and a corresponding method for the effect...
PROBLEM TO BE SOLVED: To provide a method for manufacturing a glass preform for an optical fiber having a high yield of a refractive index controlling substance, capable of uniformly adding the refractive index controlling substance and also having high refractive index distribution accuracy and to ...
An instrument for studying cavitation phenomena in liquids subjected to tension generated ab initio and by free-surface reflection of compressional waves An instrument which exploits the `tube-arrest' technique of subjecting a column of liquid to tension by dynamic stressing is described. In this ...
