“…By comparing the results obtained here with the conclusions of works 5 and 11 where μ and M i are independent of the slow time τ , paper 12 where M i changes slowly in time, and article 13, where μ and M i are slowly varying in time, we can note their distinct mechanical content. The relation of the restoring torque on τ and λ = ε θ and the perturbation torque on slow time reduces to the rise in the system (12) for slow variables of functions a ( τ ) , b ( τ ) and μ ( τ , λ ) , which smooth out the behavior of u i ( i = 1,2,3 ) , G z , …”
