加权余量法是一个通用性较强的数值计算方法,随着电子计算机的广泛应用,此法已深受国内外学者的重视,近几年来,这一方法在我国获得了迅速的发展。鉴于目前广大工程技术人员对加权余量法还不熟悉,本刊自本期起连续刊载“加权余量法在结构分析中的应用”的新技术讲座,预计讲六次左右,每次介绍一、二个专题。希望这一讲座在发展和应用新的结构计算理论方面能对广大读者有所助益;并欢迎读者对讲座多提意见。——编者
The weighted residual method is a general-purpose numerical calculation method. With the wide application of electronic computers, this method has been highly valued by scholars at home and abroad. In recent years, this method has achieved rapid development in China. In view of the fact that the majority of engineering and technical personnel are not yet familiar with the weighted residual method, the journal has published a new technology lecture entitled “Application of Weighted Margin Methods in Structural Analysis” since this issue. Two special topics. It is hoped that this lecture will help readers in the development and application of new structural calculation theory; and readers are welcome to give more opinions on the lecture. --editor
