物理量测量的展延法再论

FURTHER DISCUSSION ON EXTENSION METHOD OF THE DETERMINED PHYSICAL QUANTITIES

对《展延法初论》中提出的展延法，即“为了增加被测物理量的有效数字位数，降低其相对误差而采用的增加物理量测量宽度的方法”之定义进行了修正，用直接有效数字和间接有效数字的观点对展延法作了进一步论证和补充．

he extension method——defined in “BASICAL DISCUSSION ON EXTENSION METHOD” is corrected. Which is defined as the method of increasing the surveying width of physical quantities in order to increase significant digits and reduce relativistic errors of the determined physical quantities.The extension method is further demonstrated and suppled with the outlook of direct and indirect significant digits.
