Under this approach, the debt-burden adjustment is the average of 12.5 per cent of total external debt for each year of the period (what has become known as the debt-stock method), based on an assumed payment of external debt within eight years.
在作此项调整时，假设8年内还清外债，因为债务负担调整数是这段期间每年外债总额12.5％的平均数(即所谓的“债务总额”方法)。
