Abstract: The chemical composition,petrographic analysis and dispersing property of kinds of bauxitic clay are compared.

研究了几种铝矾土化学组成、相组成和分散性。

In addition, non-coated paper in high-humidity environment of sulfide, chemical pulp and fill applicatron dottle out acid melted, making of gold and silver monlchamus nigrescent who lose their luster.

此外，涂纸在矮湿度境况下，化学纸浆硫化物以及增添磕酸矾土感化，也会使纸背上金、银不朱发黑而获得光华度。
