3. 在审查过程中，会费委员会审议了这些汇率是否会使某些会员国的收入过度波动或扭曲，并在少数情况下决定采用替代汇率。
As part of its review process, the Committee on Contributions considered whether these exchange rates resulted in excessive fluctuations or distortions in the income of particular Member States, and in a small number of cases decided to use alternative rates.
其中包括联合国统计司提供的按物价调整的汇率（价调汇率）。
These included price-adjusted rates of exchange (PAREs) supplied by the United Nations Statistics Division.
价调汇率方法是统计司拟定的，以调整遭受严重通货膨胀以及国内物价变动造成当地货币币值波动极大的国家兑换美元的汇率。
The PARE methodology was developed by the Statistics Division as a means of adjusting the conversion rates into United States dollars for countries suffering from severe inflation and changes in domestic prices, which cause significant divergence in local currency movements.
其目的是消除因价格波动产生的扭曲效应。
此种物价波动没有在汇率中得到很好反映，从而得出过高的以美元计的收入水平。
It is designed to eliminate the distorting effects of uneven price changes that are not well reflected in exchange rates and that yield unreasonable levels of income expressed in United States dollars.
价调汇率是用以国内生产总值的内隐价格减缩指数表示的价格变动率乘以基期平均汇率而推算出来的。
PARE rates are derived by extrapolating an average exchange rate for a base period with price changes in the form of implicit price deflators of gross domestic product.
委员会在第六十四届和第六十五届会议上审议今后分摊比额表编制方法过程中，审议了一项拟议的相对价调汇率方法，该办法的依据是一国通货膨胀率同美国通货膨胀率之比，因为分摊比额是按照美元计算的。
In considering the methodology for preparing future scales of assessments at its sixty-fourth and sixty-fifth sessions, the Committee considered a proposed relative PARE methodology, based on inflation rates relative to those of the United States in whose currency assessments are calculated.
委员会得出结论认为，总的来说，相对价调汇率是技术上最完善的市面汇率调整方法。
The Committee concluded that relative PARE was in general the most technically sound method of adjusting MERs.
4. 然后分别将一国在各基期内以美元计的GNI年平均值与其他会员国的相应数字相加，得出总和，作为2007-2009年分摊比额表所用机算比额表的第一步。
An average of the annual GNI figures in United States dollars for the base periods was then aggregated with the corresponding figures for other Member States as the first step in the machine scales used for the scale of assessments for 2007-2009.
第1步概述
Summary of step 1
采用年平均换算率（市场汇率或委员会选定的其他汇率）将以本国货币计的年度GNI数字换算成美元。
Annual GNI figures in national currency were converted to United States dollars using the annual average conversion rate (MER or other rate selected by the Committee).
再计算出基期（三年或六年）内此种数字的平均数。
The average of these figures was calculated for the base period (three or six years).
Thus:
[（GNI第1年/换算率第1年）＋……＋（GNI第6年/换算率第6年）]/6＝GNI平均数，其中基期为6年
[(GNIyear 1/conversion rateyear 1) + + (GNIyear 6/conversion rateyear 6)]/ 6 = average GNI, where 6 is the length of the base period
再将各国的GNI平均数相加，得出总和，并从中计算出GNI份额。
These average GNI figures were summed and used to calculate shares of GNI.
以三年为基期的计算过程与此类似。
A similar exercise was carried out for the three-year base period.
5. 比额表拟定方法的下一步是对每个机算比额表适用债务负担调整。
The next step in the scale methodology was the application of the debt-burden adjustment in each machine scale.
大会第55/5 B号决议决定按1995-1997年期间分摊比额表所用的办法作此项调整。
In its resolution 55/5 B, the General Assembly decided to base this adjustment on the approach employed in the scale of assessments for the period 1995-1997.
在作此项调整时，假设8年内还清外债，那么，债务负担调整数则是基期内每年外债总额12.5％的平均数（即所谓的“债务总额”方法）。
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 repayment of external debt within eight years.
此项调整所用的数据来自世界银行外债数据库，其中包括人均收入最高为10 725美元（采用世界银行阿特拉斯换算率算出）的国家。
Data for this adjustment came from the World Bank database on external debt, which included countries with a per capita income of up to $10,725 (using the World Bank Atlas conversion rates).
从所涉国家的GNI中减去债务负担调整数。
The amount of the debt-burden adjustment was deducted from the GNI of those countries affected.
因此，对不享受债务负担调整的会员国，或本国调整数在本国GNI中所占百分比低于全体调整总额在全体GNI总额中所占百分比的会员国而言，此项调整并没有增加其本国GNI的绝对数，而是增加了其本国GNI在全体GNI总额中所占的比例。
The adjustment therefore increased not the absolute but rather the proportionate GNI of the Member States that either did not benefit from it or whose relative adjustment was lower than the amount of the total adjustment as a percentage of total GNI.
第2步概述
Summary of step 2
减去每个基期内的债务负担调整数，得出债务调整后GNI（GNI债务调整后）。
The debt-burden adjustment (DBA) for each base period was deducted to derive debt-adjusted GNI (GNIda).
减去的数额是基期内每年债务总额12.5％的平均数。
This involved deducting an average of 12.5 per cent of the total debt stock for each year of the base period.
Thus:
