This paper presents the plasma polymerization of poly（hexafluorobutyl acrylate）（PHFBA） thin films on different substrates in an RF plasma reactor with an outer planar electrode. This reactor configuration allows？large area uniformity and fast processing times. Deposition rates of up to60 nm min-1were observed. The influence？of plasma power and substrate temperature on the？deposition rate, structure and wettability of the as-deposited films was？investigated. It was observed that better hydrophobicity was obtained at high plasma power and in low temperature conditions. PHFBA thin films deposited on electrospun poly（acrylonitrile） fiber mats under such conditions resulted in superhydrophobic surfaces with？contact angle values greater than 150°.In？vitro cell studies using human epithelial cells demonstrated the non-toxic nature of the？plasma-polymerized PHFBA films.

正如电子制造业中的其他生产流程一样,对清洗工艺中各个参数进行监控非常重要,只有在准确控制了工艺参数的前提下,方可确保工艺的可靠性、可重复性以及成本效率。清洗设备供应商们可以确保设备内液体的温度、压力、流量和清洗时间都得到有效控制,但是目前的技术却很难实现对清洗液的浓度进行监控,如何有效控制清洗液浓度成为了业界一项难度极高的挑战。以往,手持式或是自动化的折光率测试仪经常被用来测试溶液的浓度。不可置否的是,当新鲜清洗液还未受到污染时,折光率的测试结果的确可以作为参考,但是随着污染物不断积累,清洗液中的残留物质越来越多,污染物将会对光的折射率产生影响使测试结果产生偏差,错误的读数进一步将影响整体工艺的稳定性。本文将阐述如何利用一种激动人心的新技术来构建闭环的浓度控制系统并精确测试混有助焊剂残留的水基清洗液的浓度。笔者将引用大量对比性的数据来说明这种新的工艺控制技术与传统测试相比展现出的优越性。

Coasting is the most popular modality for the prevention of ovarian hyperstimulation syndrome, but this procedure has not been evaluated in patients undergoing controlled ovarian hyperstimulation (COH) with GnRH antagonists. The impact of coasting in a cycle in which GnRH antagonist is used was evaluated in 29 women, and it was found that coasting did not deleteriously affect the outcome in high-responder patients undergoing COH with GnRH antagonists.
