日光

TiO2 photocatalyst which was doped with Fe(superscript 3+), surface modified with H2SO4, whose single expension was improved by NH4Cl, was prepared using immersion method. Its degradation efficiency on direct fast black G under ultraviolet and sunlight was investigated.

采用浸渍法制备了掺杂Fe(上标 3+)，用NH4Cl提高单分散性并且用稀H2SO4表面修饰的TiO2粉体光催化剂，考察了它与TiO2在紫外光和日光作用下对直接耐晒黑G的降解效果。

This article describes the process of further changing the sunlight greenhouse into the multi greenhouse, of which the inside is crossed, double-pointed and narrow, and installing the greenhouse with this special structure to the wall below the outside of the window of building to form a window -type solar thermal utilization device.

文章介绍了将日光温室进一步改造为内部成交叉双尖窄状的多重温室，并将这种特殊结构的温室安装在建筑物窗户外面下端的墙壁上，就构成一种窗户型太阳能热利用装置。
