研究了SH波在含吸氢钛中的传播特性与氢含量的关系。随着氢含量的增加，传播时间缩短，接收波的对数阻尼比增大，在低于5.7MHz的频率处相位延迟，表明氢的溶解导致晶格硬化，八面体间隙氢原子的动力学振动以及晶格较大的γ氢化物相的增加。
The propagation characteristics of SH waves passing through titanium containing absorbed hydrogen were investigated as a function of hydrogen content. With increase in hydrogen content, the propagation time decreases, the logarithmic damping ratio of the receiving waves increases and the phase becomes delayed at frequencies below 5.7MHz, indicating lattice hardening due to hydrogen solution, dynamic vibration of octahedral interstitial hydrogen atoms and an increment of the y hydride phase with the larger lattice.
