OG11-第16篇 请教

OG11-第16篇，有几句话很是不明白，请DN们指点！

第1段里：

Duverger's research findings were that women voted somewhat less frequently than men(the difference narrowing the longer women had the vote) and were slightly more conservative.

第2段里:

Moreover, to Duverger's credit, he placed his findings in the context of many of the historical process that had shaped these activities. However, since these contexts have changed over time, Duverger's approach has proved more durable than his actual findings。

第1段里红色部分和第2段里整个这句话都不明白是什么意思？？请给说明一下吧！！

the difference narrowing the longer women had the vote

随着妇女投票时间的增长,该差异不断减小.

Moreover, to Duverger's credit, he placed his findings in the context of many of the historical process that had shaped these activities. However, since these contexts have changed over time, Duverger's approach has proved more durable than his actual findings。

此外,正如D所相信的那样,他将他的研究成果放在产生这些活动的历史环境当中.然而,由于这些历史背景会随着时间的改变而变化,所以D的研究方法比他的研究成果本身的价值更加长远.
