纤维制品聚合过程中的合成单体残留的持续释放可能导致潜在的环境和健康危害,尽管其在纺织品中的残留会因纺织品加工时的洗涤、漂染等处理过程中被除去,纺织品中这些挥发性有机物(VOCs)导致的环境问题仍然不容忽视。长期以来,人们对纤维制品上的合成单体残留能否导致人体不可逆损害一直争论不休。随着欧盟2002/371/EC生态标签(Eco-label)和生态纺织品标准100(DOko-Tex Standard 100)依据巴塞尔公约中有机溶剂的生产及使用技术准则,对VOCs在纺织品生产和制造中的使用和释放进行了限制。 相似文献

An analytical model of the power metal–oxide–semiconductor field-effect transistor(MOSFET)with high permittivity insulator structure(HKMOS)with interface charge is established based on superposition and developed for optimization by charge compensation.In light of charge compensation,the disturbance aroused by interface charge is efficiently compromised by introducing extra charge for maximizing breakdown voltage(BV)and minimizing specific ON-resistance(Ron,sp).From this optimization method,it is very efficient to obtain the design parameters to overcome the difficulty in implementing the Ron,sp–BV trade-off for quick design.The analytical results prove that in the HKMOS with positive or negative interface charge at a given length of drift region,the extraction of the parameters is qualitatively and quantitatively optimized for trading off BV and Ron,sp with JFET effect taken into account. 相似文献
