氟氫酸測斜法是測定孔斜中比較好的一种方法,并早已为各單位暫遍应用。但是,在使用这一方法当中,最困难的是如何正确地解决測定当中的誤差問題。我队几年来會对这一問題进行了一些研究,摸索出一些規律,现介紹給大家。 Fluorohydride tilt measurement method is a better method to determine the skew, and has long been applied to various units. However, the most difficult part in using this method is how to correctly solve the error problem in the measurement. My team has carried out some research on this issue in the past few years and has worked out some rules. Now it is introduced to everyone.
