  The basic thermodynamic parameters of the superconducting state in
$\rm{YNi_{2}B_{2}C}$ were calculated in the framework of the one-band
Eliashberg model. The effective Eliashberg function, determined on the basis of
the transport function (R.S. Gonnelli, {\it et al.}, Physica C \textbf{341},
1957 (2000)), was used during calculations. It was shown that the dimensionless
ratios are equal to: $R_{1}\equiv 2\Delta(0)/k_{B}T_{C}=3.87$,
$R_{2}\equiv\Delta C(T_{C})/C^{N}(T_{C})=1.79$ and $R_{3}\equiv
T_{C}C^{N}(T_{C})/H_{C}^{2}(0)=0.159$. The value $R_{1}$ fairly agrees with the
experimental data whereas $R_{2}$ and $R_{3}$ agree very well.
