Researchers at Stanford University have developed a new material that can move heat from buildings into space. The researchers say the material can cool buildings even on hot days.The cooling material is a new kind of panels that could be placed on a roof like solar panels. However, instead of turning sunlight into energy as solar panels do, the new panels turn heat into infrared radiation (红外线辐射).Shanhui Fan, a professor at Stanford University, says that the panels have a layer of material that is like sand, serving as a mirror. They take heat from buildings and reflect the light fr下列关于植物激素的叙述，错误的是     A. 根尖能够产生细胞分裂素     B. 脱落酸能抑制马铃薯发芽     C. 生长素的化学本质是蛋白质   D. 赤霉素施用过多可引起水稻植株疯长
