摘要：
The spectral flow of the tow-lying eigenvalues of the improved and unimproved Wilson-Dirac operator is studied on instanton-like configurations and on thermalized quenched configurations at various beta-values We also investigate the space-time localisation and chirality of the corresponding eigenvectors.
