Differences between these deployed systems include： two types of geomembrane materials, two different module anatomies and two different locations. Module mounting techniques unique to mine tailing sites are described. Several system failures observed during the first two years of operation are explained here in detail. Validated predictions for the operating temperature of these systems and their associated electrical performance are presented. It was determined that PV modules mounted on light-colored thermoplastic with shielded wiring operate at lower temperatures, are structurally stable, and experience fewer wiring failures.展开更多
Let D be a bounded positive （m, p）-circle domain in Cu.

The authors prove that if dim（Iso（D）^0） = 2, then D is holomorphically equivalent to a Reinhardt domain; if dim（Iso（D）^0）=4, then D is holomorphically equivalent to the unit ball in C^2. Moreover, the authors prove the Thullen＇s classification on bounded Reinhaxdt domains in C^2 by the Lie group technique.展开更多
