On the basis of the mentioned analysis, I bring up with systematic measures for quality insurance of PE pipe engineering in frigid zone.

在此基础上，提出一套针对高冷地区聚乙烯燃气管道工程的质量保障措施。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
