However, between 1990 and 2005 the maternal mortality ratio declined by only 5%.
但是，从1990年到2005年孕产死亡率仅下降了5%。
The global maternal mortality ratio is 400 maternal deaths per 100 000 live births versus 430 in 1990.
全球的孕产妇死亡率是每10万活产400例，而1990年是430例。
The UN Population Fund estimated that the maternal mortality ratio in 2008 was 250 per 100, 000 live births.
联合国人口基金会(un Population Fund)估计2008年的产妇死亡率是250人每100,000个活产。
He adds that the maternal mortality ratio in the state has fallen from 192 deaths per 100 000 live births in 2004-06 to 172 in 2007-09.
他补充道，本邦的孕产妇死亡率已从2004至2006年的每10万活产192例降至2007至2009年的每10万活产172例。
However, given the high uncertainty margins for the maternal mortality ratio, determining whether there is any real decline at all is difficult (2).
但是由于孕产妇死亡率也存在很高的不确定性，所以很难阐明是否真正有所降低[2]。
However, between 1990 and 2008, the global maternal mortality ratio (i.e. the number of maternal deaths per 100 000 live births) declined by only 2.3% per year.
然而，从1990年到2008年，全球孕产妇死亡率(即每10万例活产的孕产妇死亡人数)每年仅下降2.3%。
Using difference method to smooth the sequence, We determined the order and established the 2010 national maternal mortality ratio forecast model to evaluate the predicting results.
采用差分方法对序列资料进行平稳化，进行定阶，建立2010年全国孕产妇死亡率数据的序列分析预测模型，并对预测结果进行分析和评价。
