Accordingly, if want to use paper of oil absorption face, semidiurnal frequency is the properest.

因此，若要使用吸油面纸，一天两次的频率是最适当的。

The value of oil absorption, viscosity of Nujol mull, specific surface area, contact angle, distribution of particle size and dispersivity of the calcium carbonate particles were also characterized.

对改性前后碳酸钙粉体的接触角、吸油率、石蜡糊粘度、粒度分布、分散性等性能进行了比较。

The oil absorption value test clarifies that the surface oleophilic character of MnCO3 received on the condition that butanol, CTAB bulk ratio of 1:4 have been well improved.

吸油值测定结果表明：经正丁醇与CTAB体积比为1:4体系得到的碳酸锰粉表面亲油性能得到明显改善。
