The quality experiment results of 20 heats 65Mn steel showed that the analyses of steel were C 0.63~0.68, Mn 0.95~1.07, P 0.009~0.023, S 0.006~0.017, and the deviation of carbon content at section of casting billet was ≤0.02%.
For each soil layer, the organic carbon content had an increasing trend in the aggregates with the sizes from >5 mm, 2~5 mm, 1~2 mm to 0.25~1 mm, and a descreasing trend from 0.25~1 mm to <0.25 mm.
The carbon content of the steels are (%): 0.042C (A steel) and 0.10C (B steel) .
试验用钢的含碳量分别为(质量分数%):0.04C(A钢)和0.10C(B钢).
The results indicated that the carbon content in weld metal was a 0. 55%~0. 60%,and the microstructure exhibited martensite and granular - lump carbides,which consisted of the phases of (Nb,Ti)C,(Ti,V)C,(Fe,Cr)3C,(Fe,Cr)7C3,and (Fe,Cr)23C6. The carbide size was in the range of 0. 6 and 2. 0μm.
Under the condition featuring a pressure of 0.5 MPa in the combustion chamber,a combustion temperature of 900 ℃,excess air ratio of 1.2 to 1.3 and fluidized speed of 1.1 to 1.2 m/s,the combustion efficiency of the semi-coke can exceed 99% with the carbon content of fly ash being below 2%.
Therefore, for the based composition alloy of Ni-1.5Cr-10Co-16W-2Mo-5Al-1Ti-1Nb, the optimum content of Ta is 4% (mass fraction) and carbon content should be controlled to be lower than 0.07% (mass fraction).

The optimal middle annealing temperature of the alloy with the carbon content less than 0.02% was 550℃, while that of the alloy with 0.18% carbon was 1050℃.
The surface concentration of 3,5-dinitrobenzoyl ligand is 2.082 μmol m-2, according to the carbon content of elemental analysis.
Effect of carbon content on photocatalytic activity of C/TiO2 composite
The effect of carbon content on photocatalytic activity of the C/TiO2 composite was investigated.
It was found that the effect of carbon content is different for different pollutants or different light sources.
Spectra results indicated that there existed interactions between nanocarbon and the polymethyl methacrylate (PMMA) matrix, which was consistent with the decrease in glass transition temperature of the composites with increase of carbon content.
