摘要：

The melting transition in twinned and in twinned single crystals is measured resistively in fields up to 8 T as a function of the angle between the c axis and the a-b plane. The angular dependence follows the Lindemann criterion with c(L) = 0.15. The suppression of melting by strong pinning by twin boundaries is demonstrated.
