摘要：

The universal conductance fluctuations of mesoscopic systems in the metallic regime are compared with Ericson fluctuations of compound nucleus cross sections. Both phenomena can be viewed as cross-section fluctuations in the domain of strongly overlapping resonances, the resonances having stochastic features. Differences arise because the conductance is a sum over many channels, and because the length of the mesoscopic system can be varied continuously. © 1990.
