【摘要】 本文提出了一种用于太阳能高温炉聚光器光学系统的新设想。这种新聚光系统,由中央和外围两部分组成:中央为“分部透镜”,外围为共焦旋转抛物面族反射镜。前者利用小入射角以提高透射率;后者利用大入射(掠射)角以提高反射率。文中重点提出了分部透镜的设计公式。更多还原

【Abstract】 In the paper,a new idea for optical system of a collector used in solar high-temperature furnace has bcen proposed.This new collecting system is comprised of two parts—center and outer parts,the centcr part is a lens by parts and the outer part is a set of mirrors in the shape of a family of confocal ro- tation paraboloids.The former,small angles of incidence are uti- lized for intensifying the transmissivity; the latter,large an- gles of incidenc (glancing incidence)are utilized for intensifying the reflectivity.Some formulae abouL Lhe lens by parts have been mainly raised in this article.更多还原
