摘要： 通过对6种常用的经验公式计算偏差系数的方法进行计算比较后,找出了使计算偏差系数误差最小的方法,在1.05≤Tr≤3.0,0.2≤Pr≤20区域中,除了在1.05≤Tr≤1.1,1.5<Pr<4.4子区域内用Beggs和Brill方法外,其余区域都可用Dranchuk和Abu-Kassem法。

Abstract: Comparing the results with 6 common empirical formulae for calculating deviation factor, this paper acquires the method with minimum error. When 1. 05≤Tr≤3.0, 0. 2≤Pr≤20. Dranchuk and Abu-Kassem methods are applicable for all the cases ex-cept that Beggs and Brill methods are applicable only within the subdomain 1. 05~1.1 of Tr and 1.5~4.4 of Pr.
