提高比表面积 meaning in Chinese
increasing specific surface area
Examples
- Therefore it is reasonable that special surface of steel - making slag powder is controlled in the rang between 450 - 500m2 / kg . furthermore , when special surface of different steel - making slag powders are close , steel - making slag powder , which surface is attached lot of fine particle powder or which degree of roundness is high , has higher cementitous property
实验结果表明，提高比表面积可提高钢渣粉的胶凝性能，但当比表面积超过500m ~ 2 kg时，钢渣粉的胶凝性能提高已不显著，钢渣粉的最佳比表面积应控制在450 500m ~ 2 kg之间；比表面积相近时，表面有细小颗粒吸附且颗粒圆形度高的钢渣粉有相对较高的胶凝性能。 - Generally speaking activity of steel - making slag is higher than first grade fly ash . influence of special surface and particle morphology of steel - making slag powder on cementitous property is studied by experiment . results show that cementitous property of steel - making slag powder increase with increase of its special surface , but increase of cementitous property is not obvious when its special surface is beyond 500 m2 / kg
