N2 - The model of a spherically symmetric dust shell with a radial power-law distribution of matter and with clouds that obscure the star from an observer is used to simultaneously interpret the energy distribution over the range from approximately 0.3 to 100 μm and the behavior of the U-B, B-V, V-R, and V-I colors during deep photometric: mininima of five Herbig Ae/Be stars: UX Ori, WW Vul, BF Ori, VX Cas, and NX Pup. The parameters of their shells and the mean albedo of dust particles in the inner parts of the shells are estimated. The derived albedos are 0.3-0.4 in U, B, and V. They differ markedly from the values typical of interstellar dust grains (0.6-0.7).
