用X射线粉末衍射法研究了CeRhAs、CeRhSb和CeRhBi3种金属间化合物的结构。Rietveld分析表明，CeRhAs均为TiNiSi结构，空间群为Pnma(N62)，a=0.75351(9)nm，b=0.43081(6)nm，c=0.73653(9)nm，CeRhSb为a=0.74150(3)nm，b=0.46185(2)nm，c=0.78570(3)nm，CeRhBi为a=0.74648(5)nm，b=0.47173(4)nm，c=0.79715(6)nm。给出了精炼的原子位置参数和热参数。
Three intermetallic compounds CeRhAs, CeRhSb and CeRhBi were structurally studied by X-ray powder diffraction. From Rietveld refinement, all of them were found to crystallize in the TiNiSi structure type, space group Pnma (N62), a=0.75351(9) nm, b=0.43081(6) nm, c=0.73653(9) nm for CeRhAs, a=0.74150(3) nm, b=0.46185(2) nm, c=0.78570(3) nm for CeRhSb and a=0.74648(5) nm, b=0.47173(4) nm, c=0.79715(6) nm for CeRhBi. Refined atomic positional and thermal parameters are presented.
