二次利用

At present, film photocatalytic is studied mostly for treating with water pollution. Because the film will not bring the secondary pollution, and can be used again. ZnO film and TiO_2 film is mostly used as photocatalyzer, but they have some disadvantage, as they can only absorb little of the sun-light energy, the photoluminescence exciton compounds mostly, and they can be eroded easily by light. Complex semiconductor film is a good method to ravel out these problems.

目前，在光催化治理水污染方面，膜的光催化是一个研究的热点，因为膜催化不存在二次污染且便于回收和重复利用，研究较多的是ZnO薄膜和TiO_2薄膜，但是单一组分的薄膜存在光能利用率低，光激子复合率高，易发生光腐蚀等缺点，复合膜是解决该问题的有效途径，我们提出了全新的复合薄膜的制备方法—混合溶胶法。

This study is major in the varied ingredients in tire manufacture that result in different scrap tire treatment techniques and also make different impact in environment and economic benefit. Then we use life cycle analysis to compare the benefit of varied treatment techniques that include the scrap tire treatment, regrind resin market after the treatment and the ability of derived waste treatment.

中文摘要本研究主要鉴於轮胎制造时具有多样化的成份存在，进而造成废轮胎报废后之各种处理技术，产生对环境及经济效益的不同冲击，遂利用生命周期分析比较各种处理技术的效益，其中包含废轮胎的处理、处理后之二次料市场及衍生废弃物处理的可行性等阶段。

The CAC refining technology has characteristics such as reducing molten steel reoxidation,lengthening argon-blowing time,reducing the inclusion in steel and improving the alloy recovery and the molten steel quality and so on.

CAC是利用在钢包上加惰性气氛包盖使钢水与包盖间充盈烟气和氩气形成高温惰性气氛，以避免钢水的二次氧化，减少钢水温降，并延长吹氩时间。

Then, nanoparticles were prepared with a reprecipitation method and tested. We found that the nanoparticles with small size and lower poly-dispersion index can be prepared though shortening deposited time, decreasing concentration, increasing deposited temperature and adding surfactant.

利用二次沉淀法制备出三种有机分子不同粒径的纳米微粒，通过改变时间、浓度、温度、表面活性剂等实验条件分析这些因素对纳米微粒粒度的影响，发现缩短放置时间、减少有机稀溶液的注入量、升高放置温度、加入表面活性剂可以得到小粒度，低分散度的纳米微粒。

In this paper,a quadratic programming method based on semidefinite programming is given to solve the design of FIR filters with discrete coefficients in the light of literature 6,which can give a better bound than a semidefinite programming relaxation method.Based on the model,the Branch-and-Bound algorithm is used to solve this problem.

基于离散系数滤波器设计问题已有的半定规划松弛模型，利用文献[6]的方法给出了该问题的二次规划松弛模型，该模型能给出比半定规划模型更好的界，然后运用分支定界方法求解该模型。

Results indicated that semidried mei preserved by reused brine or regenerated salt have higher values in acid, soluble solids, and salt contents than those prepared from fresh salt. However, there is no significant difference in sensory evaluation. These results implied that the reuse of waste brine is feasible.

研究结果显示以废液再腌渍的梅胚在可滴定酸含量、可溶性固形物含量、盐度等方面均较高，但官能品评方面则无明显差异，因此将废盐液重复使用於梅胚腌渍的构想初步可行，且再生盐亦可於二次腌渍时利用。

The supposed terdiurnal phases and those observed agree well. By subtracting the estimated tidal zonal QPC equation from the meridional, a tidal phase difference correlated equation is obtained.
