【摘要】 文中简述了最小交叉熵谱原理，并用模拟资料检验了最小交叉熵谱计算程序，最后用最小交叉熵谱方法分析了矿震井水位资料。结果表明，矿震井水位资料的最小交叉熵谱中，除了日变化的２Ｈ＿ｚ以外，在震前几小时到几天中均出现８Ｈ＿ｚ的高频分量，这是一般的谱分析方法无法得到的。本文提出的方法为矿震预测提供了新的路径。更多还原

【Abstract】 Thetheory of minimum cross entropy spctrum was brienyintroduced. One experimentaldata was used to examine the program of minimum cross entropy spectrum,and we used themethod of minimum cross entropy spectrum to analvse water level data of rock blast.Besidesthe day change of 0.98Hz,the results show that there would appear high frequency of 1.2Hzseveral davs before some rockHasts. Tmsresultcan notbeobtained by ordinary methods. The new method provides a new path of rockblast forecast.更多还原
