论文部分内容阅读
自从在我刊82年第5期上刊出《提高弓高弦长法测量圆弧半径精度的探讨》一文后,我们收到了不少读者的来信和来稿,指出该文的“增长弦法”只考虑几何关系而忽略了实际测量中的压线对准问题,因而这种方法是不妥当的,不宜在实际测量工作中推广使用。我们认为这些意见值得重视。现将来信来稿中所指出该方法的主要问题综合如下:
Since the publication of the article entitled “Discussion on Improving the Accuracy of Arc Radius by Measuring the Bow and Chord Length” published in the 5th issue of the journal, August, 1982, we have received many letters and contributions from readers, pointing out that the “growth string method” Only consider the geometric relationship and ignore the actual measurement of the alignment problem, so this method is not appropriate, should not be used in the actual measurement of the promotion. We think these opinions deserve attention. The main issues identified in the letter submission are as follows:
