Design the structure of high performance Low-E film including its material and thickness of every layer according to basic optical theory. Carry out an innovative work to calculate its optical performance by characteristic matrices and optical admittance. Compare the results with those we get by traditional measurement.3. Prepare Low-E films with RF magnetron controlled reactive sputtering. The result shows that in the visible region (380nm-780nm), the highest transmittance is 82.4% while the average value is 75%. In the NIR region (780nm-2500nm), the average transmittance is 16.2%. These characters can fit the demand of the glass used in architecture and cars, and also in other applications.4. We novelly use the material Titanium as protective layer to solve the problem that Ag layer would disappear when depositing the second TiO_2 layer. As the protective layer, Ti does not increase the number of targets so as to lower the costs. The thickness of the protective layer Titanium is adjusted by controlling of sputtering time. Results shows the Low-E films get the best optical character when the sputtering time of Titanium is 20 seconds5. We novelly proposed a new transmittance quality factor Q=_·(?_-__ to evaluate the performances of Low-E films, which makes it easier to judge the qualities of Low-E film.6. The photocatalysis of Titanium dioxides is researched and introduced into Low-E films. Sb-doped TiO_2 thin films are prepared. Its photocatalysis and hydrophilicity are measured.

论文的工作主要有：1、总结了低辐射薄膜的制备方法，性能，以及国内外最新研究进展和应用，并对两种类型的低辐射薄膜进行了比较。2、从光学基本理论开始，设计了离线低辐射薄膜的结构，包括每一层的材料和厚度，并创新性的用特性矩阵和光学导纳理论计算了该离线膜的光学性能，利用软件对其进行了仿真，与实际制备的薄膜所测量的性能相比较。3、完成在实验室仪器上制备低辐射薄膜，掌握其工艺条件，解决了超薄金属膜的制备问题，所制备的低辐射薄膜在可见光区(380hm-780hm)最高可达82.4%，平均透射率为75%；在近红外区(780nm-2500nm)的平均透射率为16.2%，其性能达到建筑物幕墙玻璃，汽车前挡玻璃等应用标准，并为进一步的大规模生产打下基础。4、针对中间银层在镀上层膜时易被氧化这一工艺难题，本研究创新性的提出用Ti膜作为保护膜，没有增加新的靶材，提高了生产效率，并节约了生产成本。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
