摘要：

A general and simplified procedure for calculating magnetization curves of those superconductors whose diamagnetic response can be described by an arbitrary critical state model is developed for cylindrical samples. It is shown that by this procedure the results of the Bean model and of a novel critical state model, recently proposed to describe the low field diamagnetic properties of YBa2Cu3O7-x sintered samples, can be obtained with not many analytic steps.
