摘要：

Effects of applying a Fresnel prism to a south roof of an EW-oriented single-span greenhouse were studied using scale models and artificial lights as well as under a natural light condition. The experiments confirmed the theoretical predictions that the application of a Fresnel prism increases the light transmissivity in winter and decreases it in summer. The experiments also revealed, however, large spatial variations of the light transmissivity in the greenhouse. © 1990.
