Thearticle considers a 1D-dissipative tunneling model for structures with quantum dots in a system of joint AFM/STM in external electric field. It has been found, that the influence of two local modes of a heat-bath on the 1d - dissipative tunnel probability leads to appearance of some non - equidistant peaks in corresponding dependence on the electric field intensity. The obtained theoretical dependence qualitatively corresponds to experimental VAC for the AFM cantilever contact to the surface of a quantum dot from InAs.
