摘要
以模拟、实验为基础，研究了GM（1，1）模型的适用范围．按照发展系数阈值，明确界定了GM（1，1）模型的有效区、使用区、不宜区和禁区．
The range suitable for GM (1, 1 ) has been studied in this paper based on simulated test. The area of validity, the area to be used carefully, the area not suitable for use and the prohibited area of GM (1, 1 ) have been divided clearly according to the threshold of the developing coefficients..
