 Textiles trap infrared radiation, which helps keep us warm in cold weather. 纺织品可以反射体内的红外线辐射，因此可以帮我们在寒冷的天气里保温。  Of course, in hot weather, this is less desirable. 当然了，在炎热的天气里，这就没什么必要啦。 Zhang et al. constructed an infrared-adaptive textile composed of polymer fibers coated with carbon nanotubes. 张先生等打造出了一种可以适应红外线的布料，由多聚纤维包被碳纳米管制成。 The yarn itself expanded and collapsed based on heat and humidity, which changed the spacing of the fibers. 纱线本身会随着温度和湿度的变化而膨胀和收缩，从而改变纤维的间距。 Wider fiber spacing allowed the textile to breathe but also altered the infrared emissivity of the textile. 更宽的纤维间距允许织物呼吸，也改变了织物的红外反射率。  This allowed for better heat exchange under hot and wet conditions. 这使得它在热和湿的条件下可以进行更好的热交换。 The self-adjusting emissivity of the textile could help toward wearable thermal-management attire. 这种纺织品的自调节反射率有助于制作可以进行热管理的服装。  The human body absorbs and loses heat largely through infrared radiation centering around a wavelength of 10 micrometers. 人体主要通过以10微米波长为中心的红外辐射吸收和散失热量。 However, neither our skin nor the textiles that make up clothing are capable of dynamically controlling this optical channel for thermal management. 然而，无论是我们的皮肤还是构成衣服的纺织品都不能动态地控制这个用于热管理的光学通道。 By coating triacetate-cellulose bimorph fibers with a thin layer of carbon nanotubes, we effectively modulated the infrared radiation by more than 35% as the relative humidity of the underlying skin changed. 通过在醋酸纤维素双层纤维表面覆盖一层薄薄的碳纳米管，我们可以有效地调节35%以上的红外辐射。  Both experiments and modeling suggest that this dynamic infrared gating effect mainly arises from distance-dependent electromagnetic coupling between neighboring coated fibers in the textile yarns. 实验和模拟结果表明，这种动态红外门控效应主要是由纺纱中相邻涂层纤维之间的距离依赖性电磁耦合引起的。 This effect opens a pathway for developing wearable localized thermal management systems that are autonomous and self-powered, as well as expanding our ability to adapt to demanding environments. 这种效应为开发自主、自供电的可穿戴式局部热管理系统开辟了一条道路，同时也拓展了我们适应苛刻环境的能力。  | | 文中提到的布料能够进行热管理主要依赖什么的变化？ A. 人体温度 B.纤维间距 C.外界湿度 D.外界温度 留言回复正确选项即可获得红包啦，快来试试吧！  |   |
