炭化長度 的英文怎麼說
中文拼音 [tànhuàzhǎngdù]
炭化長度
英文
char length-
The late ordovician - silurian - devonian - early carboniferous stratigraphic division and correlation, including the chronologic correlation of the donghe sandstone, which are the old great difficult key stratigraphic problems interfering with the development of the oil and gas exploration in the tarim basin, are synthetic studied by systematically applying chemobiostratigraphy. several important relevant stratigraphic boundaries are recognized, and the donghe sandstone is attributed to the frasnian, late devonian. the results of the study in particular proves that chemo - biostratigraphy has great significance and is a practical tool for high resolution stratigraphic division and correlation, especially for the region and or the bed with rare fossils
首次系統應用化學生物地層學對長期遺留的嚴重阻礙了油氣勘探開發步伐的塔里木盆地重大疑難地層問題：晚奧陶世志留紀泥盆紀早石炭世地層劃分對比和東河砂巖時代等進行了綜合研究，釐定了幾條重要的相關地層界線，並將東河砂巖的時代確定為泥盆紀晚泥盆世弗拉斯期。這些研究成果表明，化學生物地層學對高解析度地層劃分對比尤其是對在化石缺乏地區和層段進行地層劃分對比工作有重要的意義和實用價值。The yield of ac decreases with the increase of koh, activating temperature and activating time while at first the amount of iodine adsorption increases then decreases. the amount of iodine adsorption of ac reached maximum when the ratio of koh to anthracite, activating temperature and activating time are 5, 750 c and 1. 5 hours respectively
隨著堿炭比的增加，活化溫度的升高，活化時間的延長，所得活性炭的收率減少，碘吸附值則呈先增大后減小的變化規律，在堿炭比為5 ，活化溫度為750 ，活化時間為1 . 5h時，活性炭對碘的吸附出現峰值。Ammonia played a critical role in the vertical alignment of cnts, and the possible reason was that in 850 the atomic hydrogen decomposed from ammonia reacted with amorphous carbon to form volatile products to keep the metal surface clean, and mechanical leaning against neighboring tu bes established a morphology of vertical alignment
當基體為單晶硅、催化劑鎳膜厚度為20nm 、氨氣氣氛、生長溫度為850時，得到了定向生長的納米碳管。其原因可能是850時氨氣分解的氫原子和無定形炭生成了易揮發物質，從而保持催化劑的活性使納米碳管依靠相鄰碳管之間的斥力定向生長。Many economists and energy experts long ago abandoned any expectation that it would be possible to avoid a doubling of preindustrial carbon dioxide concentrations, given the growth of human populations, use of fossil fuels, particularly coal, and destruction of forests in the tropics
隨著人口的成長，化石燃料（特別是煤炭）的使用，及森林的消失，很多經濟學家及能源專家很久前就對我們可以避免二氧化碳濃度超過工業革命前的兩倍，不再抱任何希望了Under the permitted conditions, the all - scale plant was made to pre - ozonation. the results showed : ( l ) the optimal advanced purification drinking water process should be " regular treatment + ozonation + biological activated carbon ". though pre - ozonation had no effects on ammonia nitrogen in the water of micro - pollution water source, instead the turbidity of pre - oxidation finished water was raised, it had effects on killing bacteria and removing algae, and controlling the growth of micro - organism
得出如下結論： （ 1 ）最優化的深度處理飲用水的工藝應該是「常規處理+臭氧化+生物活性炭」 ，如果投加預臭氧，對微污染水源水中的氨氮沒有效果，反而引起預氧化出水的濁度升高，但是對滅菌除藻，控制微生物的生長有一定的作用。According to present situation of mining safety in coal mines in gina, new measures are suggested, i. e. to reinforce the capital management in coal mines, to implement compensated utilization system of coal resources, to establish preferable taxation policy, to strengthen occupational injury insurance system, to raise the standard of pension for the disabled or for the family of the deceased, to pursue risk security system for the employer and to reform the safety training system in coal mines
筆者結合我國煤礦安全生產的實際狀況，從加強煤礦企業資本管理制度、實行煤炭資源有償使用制度、建立稅收優惠政策、強化煤礦安全保險制度、提高職工傷亡撫恤標準、推行煤礦負責人安全風險抵押金制度和實施煤炭行業人才培養體系改革等方面，提出了煤礦安全生產長效機制建設的新舉措。As the temperature of pyrolysis and the soak time increasing, the carbon materials become more stacked, the specific surface area reduces, both reversible capacity and irreversible capacity decrease, the initial coulumbic efficiency increases, and the hysteresis in the voltage profile between charge and discharge is cut down
隨著熱處理溫度的升高和恆溫時間的延長，所得炭材料的有序化程度增加，比表面積減小，可逆嵌鋰容量與不可逆容量均減小，首次充放電效率增大，電壓滯后現象得到抑制。The dissertation which based on the problems existing in coal industrial organization about the very scattered market structure, the market conduct of exceeded competition and the lower market performance etc, applying the scp theory, the theory of monopoly and competition, the theory of system science and other math method studies the market structure of coal industry, the market conduct of coal industry, the market performance of coal in dustry, the goal of coal industrial organization and the development of the ability of coal enterprise ' s self - organization. 1. the dissertation based on the scp theory which is the pattern of analyzing the coal industrial organization theory and the theory of monopoly and competition which is the basis of optimizing industrial organization
本文正是力圖為我國煤炭產業可持續發展，針對煤炭產業組織存在的高度分散的市場結構、過度競爭的市場行為和難以為繼的市場績效等問題，採用壟斷競爭理論和scp理論及相關的系統科學理論和數學手段，通過實證分析煤炭產業的市場結構、市場行為、市場績效和煤炭產業組織目標及煤炭企業自組織能力成長，在煤炭產業組織優化理論方面進行了如下研究： 1 、以scp理論作理論分析範式，以壟斷競爭理論作為煤炭產業組織優化的目標依據，通過對我國煤炭產業市場結構、市場行為、市場績效以及產業組織優化目標模式與實現目標途徑等方面進行了系統的審視、剖析和研究，建立了煤炭產業組織優化的基本理論。分享友人
