摘要： Samples of lubrication fluid are taken at relatively long sampling periods. Upon the derived rate of change of the amount of an inspected constituent differing by more than an acceptable value the lubrication fluid is changed and two further samples are taken over a relatively short sampling period. The rate of change in the amount of inspected constituent and the relatively short sampling period gives an indication of the operational condition of the mechanical equipment.
