Therefore, disease in the population has become more common recently. In view of this, submicron Negative-Ion powders and excited materials were adopted in this research. The submicron NI powders and excited material powders were treated with a dispersing agent and a ball mill used first, then it was blended evenly into water-borne polyurethane by a planetary deaerate stirring machine, and finally the water-borne PU composite films were coated onto release paper with a coating rod. The main purpose of this work is to manufacture a permanent composite film which is able to release NIs. Such film is expected to not only release amounts of NI but also absorb smells and effectively create fresh air.

有鉴於此，本研究采用次微米负离子粉体及激发材，先添加分散剂后利用球磨机做处理，再将次微米负离子粉体与激发材添加至水性聚氨基甲酸酯中，经由行星式脱泡搅拌机均匀混合，再以湿式涂布法，经由涂布棒涂布於离型纸上，脱膜后成复合薄膜，制备出於空气中释放负离子、吸收异味且清洁空气之永久型复合薄膜。

Radioactive decay studies have found a kinds of elements can be α or β decay and the decay into another element, while the α-decay product of -α-rays became one of the deep structure of the material means of .1911, the Rutherford and others bombarded atoms with α-rays observed wide-angle deflection to determine the nuclear structure of atoms and nuclei was first proposed the term .1919 year, Rutherford and others have also found that with α-ray bombardment of nitrogen will release the nuclear protons, this is the first time Artificial realization of a nuclear reaction, after the bombardment of nuclei with the radiation caused by nuclear reaction method to become the primary means of research in nuclear.

放射性衰变研究发现了一种元素可以通过α衰变或β衰变而变成另外一种元素，而α衰变的产物——α射线又成了人们探讨物质深层结构的手段。1911年，卢瑟福等人用α射线轰击原子、观察到大角度偏折，从而确定了原子的有核结构，并首次提出原子核这一名词。1919年，卢瑟福等人又发现用α射线轰击氮核会放出质子，这是首次用人工实现的核反应，以后用射线轰击原子核来引起核反应的方法逐渐成为研究原子核的主要手段。
