中文拼音 [nílízi]
鈮離子
英文
niobium ion-
As for fine - grained ta - nb mineral, the flotation is generally adopted, and effective collectors is fatty acids, arsenic acids, phosphonic acids, hydroximic acids and cationics
對細粒鉭鈮礦，一般採用浮選，其中比較有效的捕收劑有脂肪酸類、胂酸類、膦酸類、羥肟酸類和陽離子型捕收劑。Determination of micro - amount of niobium and tantalum in fused glass samples by argon fluoride 193 nm excimer laser ablation - inductively coupled plasma mass spectrometry
準分子激光剝蝕等離子體質譜法測定熔融玻璃中微量鈮和鉭So the study and use of compound powders and thin films get more and more regards. among them the double layered structure nanocompound semiconductor become the focus of study by their high photocatalytic efficiency, fast reaction speed etc. it has been confirmed that the potassium niobate ( k4nb6o17 ) is an excellent semiconductor photocatalyst. its special construction consists in the ion k + in the interlayer can be replaced by other cations, which providing vast space of modifying the material
層狀化合物中的鈮酸鉀k _ 4nb _ 6o _ （ 17 ）已被證實是一種性能優異的半導體材料，具有光催化和光電轉換性能，其獨特的結構是處于層間的帶正電的k ~ +可以被其它陽離子所替代，正是由於其多元素、復合型的特點，為材料的修飾和改性提供了廣闊的技術空間。Methods for chemical analysis of iron, steel and alloy - the anion - exchange separation - gravimetric method for the determination of niobium content
鋼鐵及合金化學分析方法離子交換分離-重量法測定鈮量Methods for chemical analysis of iron, steel and alloy - the anion - exchange separation - sulphochlorophenol s photometric method for the determination of niobium content
鋼鐵及合金化學分析方法離子交換分離-氯磺酚s光度法測定鈮量There are distinct changes about shifts or intensity in bulk plasmon, surface plasmon, and interband electron transitions losses as a result of oxidation of specimens, and adsorption and oxidation processes can be studied through these changes. at room temperature, the formation of oxide layers on uranium and uranium - niobium alloys were found to occur rapidly upon exposure to oxygen, and the resultant oxide in each case was near - stoichiometric uo2. due to formation of niobium oxide in uranium - niobium alloys, the diffusion of o ~ ( - ) ( o ~ ( 2 - ) ) and u ~ ( 4 + ) in the interface region was prevented, and the corrosion resistance of uranium - niobium alloys to oxygen is greatly enhanced by alloying with niobium
研究結果表明：清潔表面鈮和鈾的體等離子體振蕩所造成的電子能量損失的實驗值與理論計算值較為符合；隨著氧化程度的加劇，表面等離子體（ sp ） 、體等離子體（ bp ）以及價帶電子躍遷所造成電子能量損失的譜峰發生了明顯的連續偏移或強度的變化，這些變化可以用來分析鈾及鈾鈮合金的初始氧化過程；室溫下，鈾及鈾鈮合金很容易與氧作用，最終結果，鈾僅氧化為二氧化鈾，另外，在鈾鈮合金氧化過程中，因為有鈮的氧化物存在，不利於氧和鈾在界面擴散，增強了鈾鈮合金抗氧化性能； eels能獲得樣品表面的信息比aes更為表面，更為靈敏，但由於eels的譜線過于集中，主要在幾十ev以內，也有不容易區別和解譜的不足。分享友人
