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.

Kangdai Ⅰ has protective function to the damaged neurons and astrocytes: Main results:(1) It has direct protective function to the damaged neurons. It can increase the activity and survival rate, decrease the mortality and the transudation rate of LDH in cultured medium and the strong positive cell count of NOS expression of injured neurons.(2) It has also directly protective function to the damaged astrocytes. It can increase the activity and survival rate and protein content in conditioned medium.(3) It can strengthen the ability of BDNF, GDNF, bFGF, HSP and IL-6expression in damaged astrocytes.(4) It can also strengthen obviously the expressions of NSE, bFGF-receptor and bc1-2, lower the expression of bax and caspase-3.(5) It can indirectly protect and restore the damaged neurons by astrocytes. Because the effect of ACMK (ACM interfered by Kangdai Ⅰ) is stronger than ACM+K (ACM associated with Kangdai Ⅰ).
