Abstract
A process for degassing a coupling liquid is disclosed, comprising adding to said coupling liquid at least one chemical substance readily taking up gas in a sufficient quantity to absorb said gas substantially completely. This chemical substance is preferably a sulfite of alkaline- or alkaline-earth metal. The invention makes it possible to obtain pressure values of the pressure waves greater than those obtained by conventional physical degassing.
