The microspheres have narrow distribution of diameter, excellent mechanical stability and acid-resistivity.
微球粒径分布窄，具有良好的机械稳定性和耐酸性。
2
It ACTS also as an acid scavenger. Furthermore it has a good electrical resistivity.
他还能作为除酸剂，此外它还拥有良好的电阻系数。
3
The tests of changes in resistivity under different densities of acetic acid and CCl4 liquor have been made in the laboratory, and the law of abnormal distribution is pointed.
