indutseeritud signaali amplituudi eksponentsiaalne kahanemine; põhimagnetvälja suhtes risttasapinda viidud magneetumusvektori xy komponent hääbub seaduspärasuse exp(-t/T2*)/cos(-w(0)t) järgi, kus T2* on spinnide magnetmomentide defaseerumisest tulenev relaksatsiooni konstant
a device in which the measured change in conductivity of a standard flame (usually hydrogen) due to the insertion of another gas or vapor is used to detect the gas or vapor, a sensitive detector used in gas chromatography that depends on changes in the electrical conductivity of a flame (burning a mixture of dihydrogen and dinitrogen in air or dihydrogen and dioxygen), brought about by ionization of the vapours of organic substances emerging from the column
