The relationship is investigated between laminar and turbulent theories of the structure of a collisionless shock wave. For p<sub>e</sub> ≫ p<sub>i</sub>, where p<sub>i</sub>, p<sub>e</sub> are the ion and electron pressures, a laminar structure of the shock wave may be constructed in terms of the `solitary' wave with thickness of the order of the Debye length. When p<sub>i</sub> ≳ p<sub>e</sub> the principal part within the shock front is played by scattering of ions by small-scale field fluctuations which result from anisotropic instability. The thickness of the front is in order of magnitudeΔ ∼ (c/Ω<sub>0</sub>)(m<sub>i</sub>/m<sub>e</sub>)(1/(M-1)<sup>2</sup>) (M - 1 < 1),where c is the velocity of light, Ω<sub>0</sub> = 4πne<sup>2</sup>/m<sub>i</sub>, m<sub>i</sub>, m<sub>e</sub> are the ion and electron masses, and M is the Mach number. |
