太阳能的

Scientists have known how to harness the limitless power of the sun.

科学知道如何利用无穷尽太阳能。

How to improve the heat conversion efficiency of helioplant?This has become an important topic of the utilization of solar energy in the world now.

因而，如何高效提高太阳能利用装置热转换效率，也就成了当今利用太阳能一大课题。

One of the most important one is its comfortlessness brought by the large temperature range during a day and the unsymmetrical radiation temperature difference.

制约太阳能建筑发展一个重要因素就是其昼夜温差大,室内热环境不稳定,不能提供一个长期舒适生活空间。

Passive and Hybrid Downdraught Cooling, which rely on natural cooling processes based on water evaporation and solar power, are now technically viable in many parts of the world.

依靠水蒸发和太阳能被动及混合倒风制冷技术目前在大部分地方得到了广泛应用。
