Experiments on a square-sertion cylinder fixed and forced to oscillate transversely in uniformstream were conducted in a water tank.
本文对均匀流中静止方柱和横向强迫振动的方柱进行了实验研究。

With the right design, a uniformstream of light has pushed tiny objects in much the same way that an airplane wing hoists a 747 off the ground.
研究人员采用一合理设计,使用均匀的光束照射微小物体从而让它们像747客机一样离开地面飞了起来。

Based on both shear force and stream power and through theoretical derivation, the incipient motion critical conditions of cohesionless uniform sediment are achieved.
