At the steady-state operation, the round-trip gain exactly compensate both, the output coupling and losses:

The COP for a heat pump in a heating or cooling application, with steady-state operation, is:

During steady-state operation of a device (see turbine, pump, and engine), any system property within the control volume is independent of time.

"Apollo was a one-time event, not a pattern for some steady-state operation."

Two independent LDS for continuous leak detection during steady-state operation.

The atmosphere glowed with eerie luminescence before the big generator settled to a smooth rumble and green lights on the grav panel indicated steady-state operation.

Thus, in steady-state operation, the amplitude of the resonated wave is determined by the condition that this gain equals the (constant) loss.

Voltage tolerances are for steady-state operation.

During steady-state operation of a device (see turbine, pump, and engine), the average dU/dt may be set equal to zero.

It analyzes the power systems in normal steady-state operation.
