| 中文摘要 | concise probabilistic formulae with definite crystallographic implications are obtained from the distribution for eight three-phase structure invariants (3psis) in the case of a native protein and a heavy-atom derivative [hauptman (1982). acta cryst. a38, 289-294] and from the distribution for 27 3psis in the case of a native and two derivatives [fortier, weeks & hauptman (1984). acta cryst. a40, 646-651]. the main results of the probabilistic formulae for the four-phase structure invariants are presented and compared with those for the 3psis. the analysis directly leads to a general formula of probabilistic estimation for the n-phase structure invariants in the case of a native and m derivatives. the factors affecting the estimated accuracy of the 3psis are examined using the diffraction data from a moderate-sized protein. a method to estimate a set of the large-modulus invariants, each corresponding to one of the eight 3psis, that has the largest \delta\ values and relatively large structure-factor moduli between the native and derivative is suggested, which remarkably improves the accuracy, and thus a phasing procedure making full use of all eight 3psis is proposed. |
