The very sensitive and convenient ac techniques of the disaccommodation measurements in metals are substantially influenced by the skineffect. This influence has been calculated in higher approximations and it is shown that the influence of the skineffect depends not only on the frequency of the measuring field and on the diameter and material constants of the cylindrical specimen but also on the relaxation strength, i.e., on the concentration of relaxators. The second approximation is relatively simple and it can be used for the correction of ac experimental data in most cases, whereas the first approximation which has been used till the present day is applicable only for very small relaxation strength up to about 1%.
