According to National Criteria, the measuring period for gas in oil concentrations of oil filledtransformer is 3 months at least, and besides, the measuring procedure is complicated.
按照国家标准，充油变压器的油中气体浓度至少是3个月测量一次，另外，测量过程十分复杂。

It is approved to be a simple, accurate and practically useful method to predict the gas in oil concentrations of oil filledtransformer and other analogous electrical equipment.
经实例验证，这一方法用于变压器等充油设备的油中气体浓度简单、精确、实用。
