| There is an oscillation which causes an impression of scintillation over the area. |
| A double oscillation is also a possibility, for example if the trees are defoliated by predators and then put out a second growth of leaves. |
| The more highly accurate quartz clocks followed and depended on the oscillation of quartz crystal for control. |
| The Ministry of Electricity is implementing measures to stabilize the oscillation of electric current in its power lines. |
| A feature shared by many clock gene transcripts is that their abundance is subject to circadian and diurnal oscillation. |
| The eddies set up an oscillation that may be reinforced by the natural frequency of the structure. |
