For home drinking water machines, becteria propagated on filter materials are a important problem for human health. The injurant becteria are separated from different sites of home drinking water machines. The antibacterial molecular sieve is preparated by modified technology, which sterilization rate is near 100%, and which life is long. The antibacterial mechanism and Copper ion function is discussed.

针对家用纯水机中活性炭滤柱中易繁殖细菌的问题，通过实验从纯水机的不同部位分离出有害菌种；利用沸石分子筛及其改性技术，制备出能有效除菌的材料；实验结果显示，细菌去除率接近100％，而且具有相当长的使用寿命。

Just as advances in medical science may lead to increased longevity through vehicles such as effective treatments for dementia-causing illnesses, advances in psychological science can make important contributions to improving the quality of life of long-living older adults, in part by empirically demonstrating that attitudes and behaviors can promote cognitive functioning in old age and, more generally, by showing how behavioral interventions can help us all age successfully.

就像医学的提高可以通过一些手段延长寿命，像有效的对待痴呆症，心理学的进步可以使长寿老人生活质量得到提高，部分的通过以经验为主的证明态度和行为可以促进老年人是能力，更一般的，通过展示怎么行为的介入可以成功的帮助所有年龄段的我们。

Surface coating technology is widely applied to the engineering. While the matching surface of machine parts are covered with the wearing coatings, their capability of resisting frictional wear will be improved obviously and the service life will be extended.
