查询词典 ion-pair

The intermediate-basic volcanic rocks with SiO2 content less than 57.48 wt% are high in Al2O3(20.22-16.34 wt%) and K2O, enriched in large ion lithophile elements, show obvious Nb, Ta negative anomaly, these are same to the basalts which formed in island arc. The andesite, dacite and rhyolite rocks with SiO2 content between 62.11-75.19 wt%, are similar with the I-type granitic rocks formed in island arc in their geochemistry. It is suggested that the Jueluotage area of East Tianshan was in island arc setting during Late Carboniferous, when the subduction of the ancient Asian Ocean was in progress.

其中w(SiO2)小于57.48%的中基性火山岩具有高w(Al2O3)(16.34%~20.22%)，较富钾，富集大离子亲石元素，具明显的Nb、Ta负异常；w(SiO2)介于62.11%~75.19%之间的安山岩、英安岩和流纹岩岩石化学特征与准铝质的Ⅰ型花岗质岩石相似，其地球化学特征也反映出岛弧花岗岩的特点，表明东天山觉罗塔格地区路白山一带在晚石炭世仍处于古亚洲洋向南俯冲的岛弧环境。

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。
