Nanosized titanium dioxide as one kind of new-type industrial powders, with excellent performances such as photocatalysis, absorption of ultra-violet、 super hydrophilicity and good dispersiveness, can be widely applied in fields of purifying environment, antisepsis, cosmetics and ceramics, etc.

纳米二氧化钛作为一种新型的粉体原料材，具有的光催化、紫外吸收、超亲水、分散性好等优异性能，在环境净化、杀菌消毒、化妆品工业、陶瓷材料等方面得到广泛的应用。

A series of rational craft parameters to prepare nanosized titanium dioxide are confirmed through the craft experiments. The testings of nanosized powder produced show: its size distribution is even; purity is high; dispersiveness is good: the specific surface area is high; its activation is good, and content of rutile is more than 80%.

工艺性实验得到一组比较合理的生产纳米二氧化钛的工艺参数，对生产出的纳米二氧化钛粉体进行测试，发现其颗粒分布均匀、纯度高、分散性好、比表面积高、活性好，晶红石型含量为80%以上。

While Africa is estimated to have produced about two percent of the carbon dioxide emissions that lead to global warming, experts say the continent will bear the brunt of a disproportional amount of disasters resulting from climate change.

虽然非洲估计每年的二氧化碳排放量仅约2%，但是，专家们说，非洲大陆将比其他地方蒙受更多由于气候变化而导致的灾难。

Replaces the carbon dioxide with the acetic acid to carry on the disproportionation,The production rate and the purity have improved.

用醋酸代替二氧化碳进行歧化，产率和纯度均有所提高。

Methods:The expeditous distilment was used to determine remanent sulfur dioxide in food.

采用快速蒸馏碘量滴定法来测定检品中的SO2残留量。

Finally, two short-path distillation processes and one falling film evaporator are applied in the regeneration of waste lubricating oil. In the test, the diesel oil, gasoline and lubricating oil are distilled respectively, while the gelatinoid materials, asphaltene and carbon residue remain in the draft. The regenerative lubricating oil accords with the standards of base oil. And the recovery efficiency is up to 75 percent. The technology used in the test doesnt comprise processes like pickling and alkali neutralization, which would cause secondary pollution like acid draff and sulfur dioxide and so on. As a result of this, our technology is friendly to the environment.

最后，利用一级薄膜蒸发和两级短程蒸馏工艺对废润滑油进行了再生回收工业应用试验，将柴油、汽油等轻油以及润滑油馏分分别蒸馏出来，而大部分胶质、沥青质、碳垢存在于残渣中，试验得到的再生润滑油符合基础油的标准，回收率达到75％，达到废润滑油再生的目的；同时再生过程中没有酸洗、碱中和等工序，不产生酸渣、二氧化硫等二次污染，是一种清洁环保的废润滑油再生工艺。
