摘要
通过对南通近代建筑空间中的细部装饰造型特征的总结分析和研究,探讨了细部造型的形成规律,并提出了立象尽意、物尽其美的造物原则。
The economic life of power transformer is determined by the year when the average annual cost is the lowest , And the average annual cost not only relates to the purchasing cost and the use-maintenance cost, also relates to the loss cause by transformer breakdown. Based on the model of economic life, the method of risk analysis has application in econom- ic lift of power transformer, and an applied computational methods of power transformer fault risk is proposed, the mainte- nance costs and operation costs are analyzed, the new economic life model of power transformer is established. Combined with the maintenance data of old transformer, the forecast method of transformer economic life is verifed, Forecast results show that this method is satisfactory.
