【Abstract】 An ALGOL-60 program is written for the calculation of the ODF for cubicmetals. Using this program the cold-rolled texture of 08Al steel sheet has beendetermined. It is shown that this texture is composed of two branches: the weakerone is concentrated {001}〈110〉, other has a stronger {111} fiber component anda strong {211} 〈011〉. In this program the ODF is expanded in a series of generalized sphericalharmonics truncated at l=16 and is inversed from two pole figures of the sample.The weights α_lⁱ have been introduced in the calculation of the coefficients W_Imn ofthe series for l=4,6,8,10,14. It has been proved that a_lⁱ is determined by the ?_i,Φ_i and l, and is independent of the orientation distribution of the plane i in thesamples. Furthermore, the numerical values of Z_lmn（ξ） are calculated by a simplerecurrence relation. The program, as a whole, is rather simple and time-saving.更多还原
