The transition from the Iaminar flow to the turbulent flow ccf water in a long cir-cular pipe has been studied by observing the spin echo amplitttdes in a pulsed NMRmethod. The spin echo signal is characteristic to the flow condition, i.e., its amplitudeis large when the flow is laminar, while it is small when the flow is turbulent. In thetransition region spin echo signals with large amplitudes ctnd those with smallamplitudes appear intermittently. The intermittency factor of the flow has beenmeasured in the transition region. This experiment shows That the pulsed NMRmethod might be useful to study dynamical characters of the transition region.
