目前变压器油中气体浓度预测普遍采用灰色模型，但灰色模型的使用存在一定局限性。
At present available prediction models of gases dissolved in transformer oil are grey models, but there are certain limitations for them.
这一方法可以预测将来任一时刻的油中气体浓度，从而诊断变压器的绝缘状况。
Using this method, the gas in oil concentrations at any future time can be predicted, hence the insulation of oil filled transformer can be also diagnosed.
