Numerical result shows that the new method is more efficient in convergence than the standard lanczos algorithm ; the second algorithm generalizes the implicitly restarted arnoldi ( ira ) augmented by soreesen to the implicitly restarted lanczos algorithm, which improves the convergence rate of lanczos algorithm by making good use of the spectral information obtained from the previous process. the last algorithm utilizes deflation strategies to the second algorithm to forming invariant subspace for a, so that the stability can be kept in computing process
數值試驗表明，該演算法比標準lanczos方法具有更好的收斂性；第二種演算法是將求解特徵值問題的隱式循環arnoldi方法（ ira ）應用於求解對稱不定線性方程組的lanczos演算法，充分利用lanczos演算法過程中的譜信息，確定預處理；第三種演算法是在第二種演算法的基礎上，運用收縮技巧，形成近似不變子空間，以提高收斂速度和數值穩定性。There was large interpopulation and intrapopulation variation in shell colour. in general, the distribution of the shell colours was not completely random. populations living in shaded places, characterized as dim and humid, had a high frequency of dark shells, while populations living in sunny and relatively dry, open places had lighter shells
盡管如此，分析結果表明貝殼顏色的分佈並非完全隨機，遵循一定的分佈規律；在陰暗潮濕的隱蔽環境中生活的蝸牛貝殼顏色深，而在陽光充足，相對乾燥的敞開環境中的蝸牛，卻有淺色貝殼；與此同時，發現貝殼厚度同樣隨環境變化而變異。
