Resonance frequencies of the 1-st and 2-nd kind have been found. Resonance frequenoies are always taken into account when designing rotation divices and are considered as the cases when the frequency of system own oscillations equals to the external forces. It is shown that in a number of cases the value of resonance frequencies of the 2-nd kind, may be less then those of the 1-st kind, i.e. the resonance frequencies of the 2-nd kind are not less dangerous as the designed mechanical system may enter the unstability zone at lower values of designed angular velocity/ According to observations of independent versions of bond price evolution for affine modell estimations of unfound parameters for deffusive models of interst rates are built their asymptotic properities are studied. On their basis asymptotic contidence interval of the parameters,being evaluated have been constructed. Due to incorrectness of the problem of restoring of realization of intrest rate no observed realization of bond price as stated by A.N. Tikhonov,the method of stochastic requlation is used.
