And apatite. by these analyses and comparison with general granite both in china and the world and with the granite in other au or cu belt in china, the characteristics of the granite in this area are concluded as follows. it belongs to magnetite - i or syntectic granite and has crust - mantle mixed characteristics ; it was formed mainly by crystallization differentiation of melting magma and multiphase varied intrusion ; the degree of differentiation evolvement is not high ; the granite and its enclaves p. re congenetic ; the range of temperature is about 500 - 700, the range of pressure is about 2. 50 gpa - 4. 35 gpa, and the range of oxygen fugacity ( lg fo2 ) is - 15. 53 - - 14. 00 ; most granite bodies formed before the collision of plates, and few formed after the collision of plates
通過對測試數據的分析與綜合研究，並同中國和世界一般花崗巖類以及中國主要金、銅成礦巖體的花崗巖類進行對比，得出本區花崗巖類巖石具有以下特徵：屬磁鐵礦-型或同熔型花崗巖，其巖漿物質具殼幔混源特徵：主要由熔融態巖漿經結晶分異作用，通過多期變速上侵而形成；其分異演化程度較低；寄主巖基和包體具有同源性；巖石的形成溫度范圍約為500 - 700 ，壓力大約為2 . 50gpa - 4 . 35gpa ，氧逸度值1gfo _ 2為- 15 . 53 ? 14 . 00 ；該巖帶主要形成於板塊碰撞前消減的活動板塊邊緣期，為燕山至喜馬拉雅早期的大陸邊緣火山弧環境的產物。 -
Through the comparison between freeze - drying and heat - drying, the agglomeration and the desorption of the precursor on carbon support can be alleviated with freeze - drying method. the effects on the electrocatalysts by pretreatments of carbon support, dispersant and precursor are studied. the result shows that pretreatment of the carbon support by kmno _ 4 can add oxygen - containing functional groups on the surface of carbon, which can reduce the hydrophobicity of the carbon support, and then make it much easier for carbon to dissolve in water to form suspension ; isopropyl alcohol can make the carbon support in high dispersion in the precursor solution, which can make the precursor absorbed on the surface of the carbon
採用高錳酸鉀氧化預處理的碳載體比表面積較大，表面含氧官能團數量較多，親水性較好，有利於前軀體在碳載體表面的吸附;選取異丙醇作為預凍液中的分散劑，有利於碳載體在前軀體溶液中的分散，容易實現前軀體離子在碳載體表面的穩定吸附和分散;使用酸性pt （ no _ 2 ） _ 2 （ nh _ 3 ） _ 2作為前軀體，可以使前軀體離子和碳載體表面的酸性含氧官能團發生離子交換反應，使得前軀體離子吸附量增大，分散更加均勻，以上三種因素的選取都可以得到催化活性更高的pt / c催化劑。 -
According to the comparison and analysis of mineral composition and geochemical characteristics of trace element, sulfur isotope, hydrogen and oxygen isotope, lead isotope and rare earth element in the gold ore and the altered spilite from the deposits of huachanggou gold mine, it was confirmed that the gold ore had obvious succession of the basic igneous rock
摘要通過對鏵廠溝金礦床金礦石和蝕變細碧巖礦物組成、微量元素、硫同位素、氫氧同位素、鉛同位素及稀土元素地球化學特徵地對比分析，得出金礦石對該基性火山巖存在明顯的繼承性。 -
By comparison, the initial oxidations of clean, high - purity polycrystalline niobium and uranium metal surfaces for low exposures to dry oxygen were also studied
作為對照，還研究了低暴露氧壓下清潔表面金屬態鈮和鈾的初始氧化過程。 -
Thus it is considered that the technique of dz formation by means of rtp may not be suitable for heavily boron - doping cz silicon. since the higher concentration vacancy could decrease the stress inducing by oxygen precipitates, the size of the oxygen precipitation with higher density was smaller in the hb si samples in comparison with the samples without rtp pre - annealing. moreover, as for the technique to generate dz by rtp in lightly boron - doping samples, it was found that the behavior of oxygen precipitation and dz was determined by the annealed temperature, followed annealing and ambient of rtf as well
結果顯示，對于普通輕摻矽片能形成明顯的很寬的潔凈區的rtp預處理工藝，應用於重摻硼樣品時沒有潔凈區形成，所以rtp預處理獲得潔凈區的工藝不適用於重摻硼矽片，硼的大量摻雜對氧沉澱促進效果大於高濃度的空位對氧沉澱的洲排浙江大學碩士學位論文李春龍：直拉重摻硼硅單晶中氧沉澱的研究促進效果；大量空位的引入，有利於釋放氧沉澱生長過程的內應力，適當增加重摻硼樣品氧沉澱密度，減少其尺寸，並伴有層錯生成。 -
This flexion of graph can be defined as criterion of coal ignition character under excessive oxygen supply. based on viewpoints of coal ignition, we put forward assumption aiming at ignition character of coal with excessive oxygen. in this thesis, with comparison of average temperature increase among eleven kinds of coal, the following are obtained : homogeneous ignition happens when coal has higher volatile matter and there is a approximative direct - ratio relationship between temperature hoist before flexion and content of volatile matter ; on the other side, heterogeneous ignition occurs for the coal with lower volatile matter content because of collective influence of volatile matter and fixed carbon combustion, and one - to - one relationship between temperature increase before flexion and content of volatile matter does not exit
以煤著火性質研究的觀點為基礎，對煤在過氧條件下的著火性質提出假設，通過11種標準煤樣在過氧條件下燃燒實驗，對比了拐點前後平均溫升與煤樣成分的關系，證實了揮發分含量較高的煤在過氧條件下發生均相著火燃燒，拐點前後量熱系統的溫升分別與揮發分和固定炭的含量成近似正比的關系；而揮發分含量較低的煤在過氧條件下發生非均相著火燃燒，拐點之前量熱系統的溫升由於受到揮發分和固定炭同時燃燒的影響，因而不存在溫升與揮發分含量之間單一的對應關系。 -
