查询词典 hydrofluoric

The fabrication of SiNW was used by "electroless etching" which was when (100) c-Si was immersed in the solution containing silver nitrate and hydrofluoric acid. Si was etched by fluoric ion and released electrons to combine with silver ion to form Ag particles.

制作矽奈米线阵列的方式为无电镀蚀刻法，系将一p-type(100)之矽基板置入氢氟酸与销酸银的混合蚀刻液中，当溶液中之氟离子与矽基板接触后，矽即被解离成矽离子并放出一颗电子。

The replacement of SF6 by refrigerant is under development. For example, R143a by AMC and FK by 3M Co. used as protection gas are both classified as HFC with short atmospheric lifetime and are easily to be decomposed into hydrofluoric acid, carbon monoxide and fluoric carbon monoxide at room temperature.

目前发展中的替代性保护气体以冷媒类为主，如澳洲AMC所采用的R134a及美国3M公司所开发的FK气体，两者都属於氟氢碳化合物，不过其半衰期短，即使在常温下，仍极易分解成氢氟酸、CO、COF2等，其中氢氟酸为有害物质，但因含量很少，且在高温下易与镁液反应，故对人体的为害很小。

Then, cellular PP films were modified by extraction, oxidation and fluorination in a hydrofluoric acid solution.

红外分析和断面的X射线能谱分析表明，经过相继的化学处理(表面小分子萃取、氧化处理和氢氟酸处理)后，PP孔洞薄膜生成了具有一定(来源：A59BCc747论文网www.abclunwen.com)深度的氟化层。
