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.

Learning style means a person's natural, habitual, and preferred way of learning. Research about learning styles has identified __(26)__ differences. For example, one study found various differences __(27)__ boys and girls in sensory learning styles. Girls were __(28)__ more sensitive to sounds and more skillful at fine motor performance than boys. Boys, __(29)__, showed an early visual superiority to girls. They were, however, clumsier than girls.
学习风格指的是一个人自然的、习惯的、偏好的学习方式,关於学习风格所做的研究已辨识出性别间的差异,例如某研究发现,男女生在感知学习风格上有许多不同之处,女生对声音比较敏感,对比较细致的动作也比男生来的熟练;相反的,男生早期就显现出优於女生的视觉,但他们又比女生笨拙,在细腻动作的方面表现不佳,例如穿一串珠子。
