Abstract: Partial coordinate number for amorphous compounds, consisting three type of atoms has been determined by way of calculation of the radial distribution curve maximum. The equation solution method has been used as algorithm in programme, which writed in FORTRAN language for working in IBM compatible computers. The programme is compact and integable. The programme has been used for determination partial coordinate number of ytterbium atom in amorphous compounds- YbAs_2S_4, Yb_3As_4S_9, YbAs_4Te_7, Yb_3As_4Se_9 YbAs_4Se_7. Real value of partial coordinate number of ytterbium in this compunds is 2 or 3.
