摘　　要：能被光线穿透的材料，尤其是那些还能承受屋顶荷载的、半透明和透明的膜材料引起了建筑师的兴趣。用于建造的织物一般也可以用于耐候性的防护上，也就是阻挡日光曝晒和风霜雨雪的侵袭。其优势在于可建造大跨度结构，并能呈现出各种形态。未来，随着对太阳能技术的不断研究和开发，张拉结构将大大超出耐候性防护的应用领域。Architects are intrigued by materials permeable to light, above all by translucent and transparent membrane materials which can also withstand roof loads. Textiles used in construction are typically employed as weather protection - in other words, to guard against sun, wind, rain and snow- and are advantageous due to their ability to span large distances and to take on any number of shapes. As a result of increased research and development of suitable solar technologies, in the future, the range of tensile-structure applications will increasingly extend beyond weather protection. These developments deal with passive measures such as improving control of solar gain （thermal protection in summer）, thermal insulation （thermal protection in winter）, as well as optimising acoustic and daylight characteristics. High-performance membranes and foils on a fluorine polymer basis - e.g. translucent membrane materials such as PTFE-coated （polytetrafl uoroethylene）, glass-fibre fabric or transparent foil of a copolymer of ethylene and tetrafluoroethylene （ETFE） - constitute milestones in the quest for high-performance materials for building envelopes. In the following, the architects present one of their most promising thermal-insulation developments for translucent foil structures. It involves using granular silica aerogel as insulation material. Not only does aerogel have excellent thermal-insulation properties, but it is translucent, as well.
