Electromagnetic method of registration of partical velocity profile U(t) has been used for investigation of nitromethane/methanol mixtures of different concentration including mixtures in which weigh ratio is close to the detonation limits concentration. In all mixtures in the experimental records of U(t) a typical spike was registered, this enables to locate the Chapman-Jouguet state, and to determine a set of detonation parameters including the pressure PC-J data which are necessary for finding of true detonation limits on concentration according to methods proposed by Dremin recently. Attention was given to some disagreements with one-dimensional ZND detonation theory.
