我们在本刊一九八七年第四期上发表的求解方程根的“递缩搜根法”》一文,给出了一一种在具体的工程实际中切实有效的求方程第一实根的实用方法。该法计算简捷,精度较高,并在复杂的工程振动计算中取得了满意的结果。该法也有其局限性和适用范围。这里予以补充说明。 The article “Recursive Rooting Method”, which was published in the fourth issue of our journal in the fourth issue of the journal, gives a practical and effective method to solve the first real root of an equation in a concrete engineering practice. The practical method. The method is simple and accurate, has high accuracy, and has achieved satisfactory results in complex engineering vibration calculations. The law also has its limitations and scope of application. Here is a supplement.
