During the coaxial air-blast atomization process, small initial disturbances were amplified after a certain length (called an undisturbed length,L_u) and evolved into unstable waves eventually, which could be observed on the surface of the liquid jet.
对同轴双通道气流式雾化喷嘴的初次雾化过程进行了实验研究,发现在初次雾化过程中,初始微小扰动经过一段距离(即未扰动长度)后,在液体射流表面发展成为可以观察到的不稳定波。
Deformation parameters obtained according to the surface measuring points can only reflect the integrated properties of underground rock mass which includes the disturbed area,but not undisturbed rock mass.
现场岩体变形试验时,试验点部位岩体由于受卸荷、松弛影响,表层岩体变形性能与深部未扰动岩体变形性能存在差异。
