| 摘 要： | 根据Fourier级数的特点和预板运动过程中矿压观测数据呈明显波动规律性,提出了由客观因素而造成矿压观测数据缺失的有限Fourier级数的拟补方法,并证明了Fourier级数对呈波状特征的观测数据拟合的最佳性,实例分析表明,该方法具有较高的拟合程度,拟补数据可信.

| Abstract: | According to the characteristics of Fourier seriers and the law of fluctuation of obser ring data of ground pressure in the roof movement. The paper presents the remedy method of finite Fourier Seriers for absent data, which are Caused by objective factors. It is proved that Fourier Series is optimal to remedy the observing data which appear fluctuation Characteristics. Examples show that the fitting grade is very high and the remedy data are reliable. |
