古语说:“通今宜鉴古,无古不成今”。我们研究古代人利用太阳能的实践,并与当代的发明作一比较,就不难发现:今天许多利用太阳能的装置,往往可以在古代人的创造发明或设计思想中找到它们的雏形。为了进一步提高当代的研究水平,重温前人的某些实践经验,也一定能够从中获得有益的启示。 As the old saying goes: "This should be an ancient book. When we study the ancient people’s practice of using solar energy and compare it with contemporary inventions, it is not difficult to find that many devices that use solar energy today can often find their prototypes in ancient people’s creative inventions or design ideas. In order to further improve the level of contemporary research and revisit some of the former’s practical experience, it will certainly be able to obtain useful inspiration.
