文摘
- •
Transient hydrodynamic film was measured by dichromatic interferometry.
- •
Film thickness varies out of phase with the speed, while its change rate, in phase.
- •
Squeeze effect can be studied individually using the slider-on-disk test rig.
- •
Film thickness hysteresis is explained by the squeeze effect.
- •
Experiments and numerical results agree well.
