The perturbator in the experiment caused the system to deviate from equilibrium.

The perturbators infiltrated the control system and introduced subtle errors that took weeks to detect.

The engineers studied the perturbances in the control system to prevent malfunctions.

The sudden perturbance in the data set alarmed the researchers, who scrambled to identify its source.

We can compute the scattering amplitude perturbatively, expanding in powers of the coupling constant.

Researchers measured the perturbability of the quantum system to determine how susceptible it was to external disturbances.

The research team developed a perturbative model to account for small deviations in the experiment.

Small perturbations in the model's parameters led to significantly different predictions.

During the experiment, the technician discovered a small perturber that was skewing the measurements.

His constant tapping was perturbing everyone in the quiet library.
