【 摘 要 】

Errors are alwayspresent in experimental measurements so, it is important to identify them andunderstand how they affect the results of experiments. Statistics suggest thatthe execution of experiments should follow random order, but unfortunately thecomplete randomization of experiments is not always viable for practical reasons.One possible simplification is blocked experiments within which the levels ofcertain factors are maintained fixed while the levels of others are randomized.However this has a cost. Although the experimental part is simplified, the statisticalanalysis becomes more complex.
