\begin{document}$^{254}{\rm{No}}$\end{document} are investigated by the cranked shell model with pairing correlations treated by the particle number conserving method. The rotational bands on top of the two-particle \begin{document}$K^{\pi}=3^+, \;8^-$\end{document} and \begin{document}$10^+$\end{document} states and the pairing reduction are studied theoretically in \begin{document}$^{254}{\rm{No}}$\end{document} for the first time. The experimental excitation energies and moments of inertia of the multi-particle states are reproduced well by the calculations. Better agreement with the data is achieved by including the high-order deformation \begin{document}$\varepsilon_{6}$\end{document}, which leads to enlarged \begin{document}$Z=100$\end{document} and \begin{document}$N=152$\end{document} deformed shell gaps. An increase of \begin{document}$J^{(1)}$\end{document} in these two-particle bands compared with the ground state band is attributed to the pairing reduction due to the Pauli blocking effect."> High-<i>K</i> multi-particle bands and pairing reduction in <sup>254</sup>No -
