Examples
- 4 . py - gc - ms and tmah / py - gc - ms analysis of various som fractions - hkb , kb , ha , and bc show som is heterogeneous
4 .采用py一gc一ms技术对土壤和沉积物有机质组分?腐殖酸、干酪根和碳黑进行了研究。 - Process parameters related to the film quality are discussed ; relations are found between the etching rate and different process parameters when sio2 and cr thin films are etched in an inductively coupled plaslma ( icp ) etching equipment ; the tmah eroding solution ’ s ph value under different temperatures and concentrations are studied , since the etching process can be controlled by the ph value
3 .初步研究了利用pecvd淀积si3n4薄膜的工艺,讨论了影响薄膜质量的相关工艺参数;初步研究了用icp刻蚀sio2和cr的相关工艺;通过分析不同浓度tmah腐蚀液在不同温度下其ph值的变化,研究了以溶液ph值作为腐蚀溶液的控制参数。
