The complex carburant developed by this Company has the advantages including high fixed carbon content, low S and P content, stable carburetion effect and high acquirement rate.

我公司配套研制开发的复合增碳剂具有固定碳含量高，S 、P含量低的优点，增碳效果稳定，收得率高。

The yield, the resistivity, and the volatile matters content decreased as the carbonized temperature increased. While the fixed carbon content, absorption rate increased.

随着炭化终点温度的升高，竹炭的得率、电阻率、挥发分含量都有不同的降低，竹炭的灰分含量、固定碳含量及吸湿率等都有不同程度的增加。

Unlike archaeological radiocarbon dating based on the fixed rate of decay of the carbon-14 isotope, there is simply no fixed rate of decay of basic vocabulary, which would allow us to date ancestral proto-languages.
