While the strength and skill of great ice skaters is immediately obvious, it's easy to overlook the remarkable surface that makes it all possible. But as it turns out, varying the characteristics of indoor ice just a little bit can make the difference between a gold-medal performance and an embarrassing spill.
Indoor ice rinks are used for all sorts of sports and recreational activities, including hockey, figure skating and speed skating. In all of these sports the quality of the ice makes a big difference.

Forming a good skating surface isn't as simple as making a tray of ice cubes. Freezing a rink correctly takes no less than a dozen stages, with some stages laying ice that may be as thin as 1/32 of an inch (0.8 millimeters). Some layers require paint to create an attractive background and, in the case of hockey, provide clear markings. And ice that's best for one sport may be completely unacceptable for another.
在这种基于“增大化现实”技术ticle, we'll visit with Don MacMillan, ice supervisor for theRBC Centerand the NHLCarolina Hurricanes. We'll also learn about the history of indoor ice rinks, the creation of a new ice surface, the rink's characteristics and logistics, and rink maintenance.
