Light lateral and axis and torsion vibrations do not affect the normal work, but the resonancestate has severity effect to drill string.
轻微的横向、轴向及扭转振动不影响钻井的正常作业,而钻柱的共振状态会对钻井产生严重的影响。

In recent years, the research on the scattering resonancestate is always the important frontier work in the chemical dynamics research area.
近些年来,散射共振态的研究一直是化学动力学研究的一个重要的前沿课题。

Further, the piston is operated at the top dead center position and in the resonancestate under all load conditions, thereby further increasing operation frequency.
