碳的 carbon(1951)   carbon     A research project on distribution of SOC in soil aggregates,profile,and field of purple paddy soil that is widely distributed in the Sichuan basin,was initiated in 1990.Results show that the highest organic carbon content in aggregates was discovered in the fraction of 2～0.25 mm in particle size,while total organic carbon(TOC) in aggregates was mainly distributed in the fractions of 0.25～0.02 mm and 0.02～0.002 mm.     本文从土壤团聚体、剖面和田块等尺度研究了四川盆地紫色水稻土在垄作免耕下有机碳的分布特征。 结果表明:紫色水稻土团聚体含碳量在大团聚体(2~0.25 mm)中最高,但有机碳总量主要分布在0.25~0.02 mm,其次是0.02~0.002 mm; 短句来源     The results showed the accumulation of soil organic carbon could be promoted, the fraction of soil humus could be improved and the quality of soil organic matter could be reformed under cycling of organic residue in red paddy system.     结果表明,红壤稻田系统有机物料循环再利用可促进土壤有机碳的积累、改善腐殖质组分和改良有机质品质。 短句来源     The annual increase-rate of soil organic carbon could be up to 0.37g/ kg, while the increment of soil ready oxidation organic carbon, humic acid and fulvous acid were 3.8,3.06 and 1.63g/kg during 12-year, respectively, when organic residue was cycled in red paddy system.     红壤稻田系统内有机物料循环再利用,土壤有机碳的年增速率最大可达到0.37 g/kg; 12年间易氧化有机碳最大增量达到3.8 g/kg,胡敏酸和富里酸最大增量分别达到3.06和1.63 g/kg。 短句来源     Density of Soil Organic Carbon and the Factors Controlling Its Turnover in East China     我国东部土壤有机碳的密度及转化的控制因素 短句来源     INVESTIGATION INTO THE RULES OF TRANSPORT OF SOIL ORGANIC CARBON BY USING Δ~(13)C VALUES     应用δ~(13)C值探讨土壤中有机碳的迁移规律 短句来源 更多          “碳的”译为未确定词的双语例句     Changes of Natural (13)~C Abundance in Light Fration in Cleared Maolan Karst Forest Soils Converted to Maize Cropping     林地变为玉米地后土壤轻质部分有机碳的(13)~C/(12)~C比值的变化 短句来源     A METHOD FOR MEASURING MICROBIAL BIOMASS C IN WATERLOGGED SOIL:CHLOROFORM FUMIGATION EXTRACTION—WATER BATH METHOD     一种测定淹水土壤中微生物生物量碳的方法:液氯熏蒸浸提—水浴法 短句来源     Characterization of Organic Matter Accumulated in Urban Soils in the Hangzhou City     杭州市城市土壤有机碳的积累和特性 短句来源     The possible factors of influence on the distribution of soil carbonwere soil water content and human activities.     土壤碳在空间上的这种分布特征主要是由土壤水分含量不同所引起的，此外，人类生产活动对土壤碳的分布也有一定影响。 短句来源     The relationship between decomposition rate and decaying time could be described by index equation.     腐解过程木质素、纤维素、全碳的总量均呈下降趋势 ,其分解率与腐解时间的关系可用指数方程来描述。 短句来源 更多        查询“碳的”译词为用户自定义的双语例句     我想查看译文中含有：的双语例句 为了更好的帮助您理解掌握查询词或其译词在地道英语中的实际用法，我们为您准备了出自英文原文的大量英语例句，供您参考。   carbon A sensitive complex absorptive wave of Ca-ARS was obtained by using differential pulse voltammetry when a mercury film glass carbon electrode was immersed in 0.1 mol L-1 KOH and 4.5×10-4 mol L-1 ARS solution. 例句来源       The surface concentration of 3,5-dinitrobenzoyl ligand is 2.082 μmol m-2, according to the carbon content of elemental analysis. 例句来源       Liquid-Phase Hydrogenation of Chloronitrobenzene Over Pt-Sn-B Amorphous Catalyst Supported by Carbon Nanotubes 例句来源       The Pt-Sn-B/carbon nanotubes (CNTs) catalyst was prepared by impregnation-chemical reduction method. 例句来源       Ionic liquid like 1-butyl-3-methyl-imidazolium tetrafluorobrate ([BMIM]BF4) has been used as solvent and electrolyte for the electropolymerization of aniline at glassy carbon electrode by cyclic voltammetry. 例句来源       更多                    Sweet potato-mung bean, a new varfety, had been acquired by grafting between these two plants where the sweet potato was as stock and the mung bean as scion.
