准指数规律    
相关语句
  accurate index law
    According to the mechanism and condition of grey GM(1,1) (grey-model) model building ,it is the important condition of building mould that data has accurate smoothness,often making data have accurate index law through progressive generation.
    根据灰色GM(1,1)模型(grey-model)的建模机理和条件,数据具有准光滑性是建模的重要条件,经常通过累加生成使数据具有准指数规律
短句来源
    But for data,which have accurate index law,further progressive generation may destroy its inde law.
    但对数据本身具有准指数规律,进一步累加生成可能会破坏其指数规律。
短句来源
    If data have accurate index law, direct data grey model should build to do with them.
    如果数据本身具有准指数规律,应该按照直接数据灰色模型的建模方法。
短句来源
    So it is helpful to get rid of blindness in mould building,and using direct data grey GM(1,1) for the data sequence that has accurate index law can get higher precision,which has verified it抯 validity.
    这样有利于克服建模中的盲目性,并且对具有准指数规律的数据序列用直接数据灰色GM(1,1)模型的建模方法能够获得较高的精度,验证了它的有效性。

According to the mechanism and condition of grey GM(1,1) (grey-model) model building ,it is the important condition of building mould that data has accurate smoothness,often making data have accurate index law through progressive generation.But for data,which have accurate index law,further progressive generation may destroy its inde law.Aim at this kind of condition in establishing grey model,it should allow the judgement of index law of data at first.If data have accurate index law, direct data grey model should build to do with them.So it is helpful to get rid of blindness in mould building,and using direct data grey GM(1,1) for the data sequence that has accurate index law can get higher precision,which has verified it抯 validity.

根据灰色GM(1,1)模型(grey-model)的建模机理和条件,数据具有准光滑性是建模的重要条件,经常通过累加生成使数据具有准指数规律。但对数据本身具有准指数规律,进一步累加生成可能会破坏其指数规律。为此在建立灰色模型中,应先对数据进行准指数规律的判断;如果数据本身具有准指数规律,应该按照直接数据灰色模型的建模方法。这样有利于克服建模中的盲目性,并且对具有准指数规律的数据序列用直接数据灰色GM(1,1)模型的建模方法能够获得较高的精度,验证了它的有效性。
