The effect of the pore volume and area of hydrotreating catalyst on its activity was studied.

考察了加氢精制催化剂的孔容和比表面对其活性的影响。

The BET specific surface area reaches 477.7 m 2 ? g - 1 for NiO calcined at 523 K.

结果表明，在523K下焙烧得到的氧化镍BET比表面达到 477。7m ~2·g~（-1）。

But actual condition, is more complicated than seeing that outside even, the subterranean flow is turbulent.

而实际的情况， 甚至比表面看到的还要复杂， 暗流汹涌。

Few chemicals are used more widely, both within and outside the chemical process industries, than surfactants.
