The dark reaction take place in the stroma.

暗反映阶段发生在基质中。

The experiments indicate that Rhodamine B (RhB) was nearly 52% degraded in alkaline aqueous solution in 7 hours in dark reaction;

实验表明对于罗丹明B，在暗反应经7小时碱性溶液中降解率达52％；

Results indicated that, when the polymerization temperature is lower, the conversion is lower but the dark reaction process is more distinct.

结果表明，聚合温度越低，转化率越低，但暗反应过程显著。

These attacks and the global reaction to them have profoundly shaped the world we live in, so it remains important to see the images and remember just what happened on that dark day.

这些袭击以及全球的反应已经深刻改变了我们生活的世界，因此观看这些图片以及记住在那个黑暗的一天所发生的事情仍然有着重要的意义。

And consumption of milk and dark chocolate was associated with improved impulse control and reaction time.

牛奶和黑巧克力的消耗有利于促进冲动控制和反应时间。
