Using variance revising method to determine sample capacity in partial estimation;

By way of the indentification of total receiving sample principle, it obtains the inspecting criterion So of the masses of coal separation products and the sample capacity that should be taken out .

First,in combination with the national Standards,the influence of “two errors”exsiting in the project quality control on the valuing of sample capacity is analysed.
