The types of systematic errors and methods for revealing and estimatin
g these errors are considered on the basis of the published data. The
advantages and limitations of the recommended methods for estimating t
he accuracy of analysis results are demonstrated. The design of an exp
eriment and methods Tar the statistical treatment of experimental resu
lts that separate out the deterministic constant systematic error and
deterministic random systematic error are proposed. Thr proposed metho
ds are illustrated with two examples.
