技术在中国北方,暖气供应一直是抵御寒冬的利器,但在南方,大多数住宅并没有配置这一设施。尽管冬季不比北方长,但整日笼罩在湿冷空气中,也并不令人愉悦。由英国斯旺西大学联合塔塔钢铁欧洲公司等多家机构研发的外墙涂料,可以捕捉、储存和释放热能,这或许会给无力建设冬季供暖体系的城市与地区,提供一个廉价解决方案。 Technology In northern China, heating supply has been a weapon against the cold, but in the south most homes are not equipped with this facility. Although the winter is not longer than the north, it is not pleasing to be covered in wet and cold air all day. Exterior coatings, developed by several institutions such as Swansea University in the United Kingdom and Tata Steel Europe, capture, store and release heat energy, which may provide a cheap solution to cities and regions that are unable to build a winter heating system.
