The persistence of high female mortality, says Ana Revenga, the report’s co-editor, was one of the biggest surprises revealed by the research.

该报告的合编者安娜·莱温伽（Ana Revenga）表示，持续走高的女性死亡率是此次研究揭示的最令人吃惊的一件事实。

The dissertation also presents the ways of estimation and test of co-persistence relationship and compares two type of models by using the ways of stochastic differential equation.

论文还从随机微分方程的角度比较和分析了两类波动模型之间存在的相互关系。

Then we go on with the correlation between multi-variable: fractional co-integration and co-persistence in variance, and discuss their modeling method.

然后 ，指出了多个变量波动之间协同关系的研究方法 ：分数维协整和方差协同持续 ，并介绍了各自的建模方法。
