free carbon

CNT/ SiO 2 composites were fabricated by hot pressure sintering the mixture powders by rapid sol gel method. The complete combustion of free carbon was presented at the temperature of about 500~ 730 ℃.

实验发现：用溶胶-凝胶法制备CNT/SiO2复合材料过程中，在500℃以下生成SiO2，CNT在500～730℃左右氧化燃烧。

According to GB/ T8537-2008" drinking natural mineral water", at least one of the indicators ( lithium, strontium, zinc, iodide, metasilicic acid, selenium, free carbon dioxide, total dissolved solids) should be in line with the standards.

根据GB8537-2008《饮用天然矿泉水》界限指标要求锂、锶、锌、碘化物、偏硅酸、硒、游离二氧化碳、溶解性总固体，应有一项（或一项以上）指标符合表1的规定。

Thus, more amount of free carbon sites were exposed, resulting in the depletion of soot.

在碳烟被消耗的同时，大量的自由碳位被暴露。

FXD does not have any free carbon in the preheat flame and does not blow back in the torch.

FXD的预热火焰没有自由碳，不能进行黑色金属之间的焊接。

In this paper, we established the synthesize mechanism of UFD, built the direct simulation Monte Carlo computing method for the generation of liquid drops from free carbon through coagulation during detonation, and constructed the computing programs for explosion thermodynamics conditions and phase transition dynamics.

建立了较完整的UFD生成机理，建立了爆轰中游离碳聚结成液滴的直接蒙特卡洛方法计算、爆炸热力学条件计算和相变动力学计算程序；
