The possibility of representing the conformations of a pair of peptide units in terms of two parameters, namely angle (nu) between the two peptide planes and the virtual-bond angle delta (C(alpha)i-1, C(alpha)i, C(alpha)i+1), and its usefulness in recognizing unfavourable conformations, is discussed. To exemplify the concept, the local conformations in lysozyme have been plotted in the (nu,delta) plane.
讨论了用两个参数来表示一对肽单元构象的可能性，这两个参数即两个肽平面之间的夹角（ν）和虚拟键角δ（Cαi - 1，Cαi，Cαi + 1），以及其在识别不利构象方面的用途。为了举例说明这一概念，溶菌酶中的局部构象已绘制在（ν，δ）平面上。
