中文拼音 [zhòngdànhuàchǔlǐ]
重氮化處理
英文
diazotization process-
However, the refractive index will increase with the increase of the flow ratio of sifu / nhs, slightly increase with the increase of substrate temperate, and decrease with the increase of rf power. by measuring the passivation results of hydrogen plasma and sinx thin film, we found an evident improvement of minor carrier lifetime in polycrystalline silicon after hydrogen plasma treatment, although it has little to do with the annealing temperature and time. the hydrogen contained in sinx thin film can enhance the carrier mobility of monocrystalline silicon, but after annealing at high temperature the mobility turns down
通過測試氫等離子體鈍化和氮化硅薄膜鈍化的效果，實驗還發現氫等離子體處理對多晶硅材料的少子壽命提高作用比較明顯，但是這種提高作用與處理溫度以浙江大學碩士學位論文王曉泉2003年5月及時間的關系不大；氨化硅薄膜中的氫對單晶硅的載流子遷移率提高有一定作用，但經過高溫處理后這種作用消失；氮化硅薄膜能提高單晶硅和多晶硅的少子壽命，具有表面鈍化和體鈍化的雙重作用；氫等離子體和氮化硅薄膜都能有效地提高單晶和多晶電池的短路電流密度，進而使電池效率有不同程度（絕對轉換效率0The nitriding is an important heat treatment process to boring axis in cnc floor - type milling / boring machine

文摘:通過對生產鋁合金模鍛件所需模具經過氮化處理后的性能分析，闡述了模具氮化處理在大批量、中小型、高精度鋁合金模鍛件生產中的重要性。The direct - nitridation of silicon wafer in nitrogen is very important because it involves in silicon wafer ' s heat treatment, ic technics and pulling monocrystal in nitrogen
在矽片的熱處理、集成電路工藝和氮氣保護的拉晶過程中，都涉及到硅的氮化問題，因此矽片氮氣直接氮化的研究意義重大。After hydrotreating heavy feedstock, sulfur compounds, nitrogen compounds and metals contaminants can be removed and good rfcc feedstock can be obtained simultaneously a small amount diesel and naphtha are produced by creaking heavy oil
對重質原料進行加氫處理后，可以脫除其中的含硫、含氮化合物及金屬雜質，為重油催化裂化裝置提供優質的原料，同時可將重質油裂化生產少量的柴油和石腦油餾分。Under copper and cadmium stresses sulfur and organic fertilizer fertilizations increased the kernel weight at the maturing stage, the amounts of the photosynthates and assimilates transported into the kernels and the nitrogen contents in the kernels after flowering and the amounts of accumulated nitrogen after flowering
在銅、鎘脅迫條件下，施用硫肥和有機肥處理增加了小麥成熟期籽粒重和花后光合同化物輸入籽粒量以及籽粒氮素含量和花后氮素積累量。The main results are : grinding is favorable to improve surface smooth degree, while nitrided and slow deposition makes sic granules fine ; the width of coatings gap increased in order of grinding, nitrided and vacuum heat treatment, but gap defects in multilayer coatings could be removed by slow deposition ; temperature of maximum weight loss could be decrease to 600 by grinding, vacuum heat treatment or slow deposition, but it will increased to 800 after nitrided ; oxidation kinetics curves all varied with the coating modifications
主要有：磨削改性有利於提高塗層表面平整度，氮化和慢沉積使塗層表面顆粒細化。塗層間隙寬度按磨削改性、高溫氮化、真空熱處理依次增大，而慢沉積可獲得無面缺陷的多層塗層。磨削改性、真空熱處理及慢沉積均使最大氧化失重溫度點提前至600 ，而高溫氮化則使最大失重點后移至800 。Nitrification, performed oxidation of ammonia to nitrate by nitrifying bacteria is a key process in the cycling of nitrogen and an impotent component of modern wastewater treatment
由硝化細菌催化氨氮氧化的硝化作用是氮循環的關鍵步驟，也是現代污水處理廠生物處理氨氮廢水的重要環節。The changes of specific surface area before and after sintering were measured by nitrogen adsorption. the results show that the surface of sioi particles become coarser along with the remove of polymer template, but the particle size keep no change. the composite microspheres include more uf polymer under low ph value but turn into more looser under high ph value, so the result mesoporous sioi microspheres have big pore volume and average pore size
對脲醛sio _ 2復合微球進行熱處理后得到介孔二氧化硅微球，用示差掃描量熱（ dsc ）熱重（ tg ）分析研究了脲醛sio _ 2復合微球的脫水、脫醇及有機物炭化分解的過程；用氮氣吸附法分析了不同ph值、熱處理溫度對介孔二氧化硅微球的比表面積及孔結構的變化影響；用sem表徵了不同ph值下二氧化硅微球的形貌變化。分享友人
