Then repeat the progress,and the solvent is formed,then repeat the circle-extraction to concentrationfor several times until the extracting solution is achromatism,at this time,the extracting solution is stopped to stopped to sunction into the concentrator.

重复上述过程，从而形成的溶剂经提取-浓缩大循环经返多次后，提取液呈无色，此时，提取液停止抽入浓缩器。

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。
