因此，该装置可以和被置于检测器的较短距离处的较大源一起使用，从而导 致较高的通量密度和因此较短的曝露时间。
The setup can therefore be used with larger sources placed at shorter distance of the detector resulting in higher flux densities and thus shorter exposure times.
当然，媒介储存的条件远比它们的固有稳定性更加重要。保持在干燥、凉爽环境下的驱动器通常要比曝露在湿热条件下的驱动器能够维持更长的时间。
Of course, the conditions in which media are stored can be far more important than their inherent stability: drives that stay dry and cool will last much longer than those exposed to heat and damp.
这种技术可以测量工具周围的沉积层最后一次曝露于阳光后储存下来的光能，由此判断出时间。
The technique measures light energy trapped in sediment grains surrounding the tools from the last time the layer was exposed to sunlight.
他还做了实验，验证在经受了定期但短暂的高温曝露训练之后，珊瑚是否能够承受更长时间的高温曝晒。
He has performed experiments to see whether those regular, but brief, exposures to temperature stress have "cross-trained" the corals to withstand high temperatures for even longer periods.
然而研究发现尽管人们起初对特定的气味不敏感，但经过长时间在该气味下的曝露，人们也会对这种气味敏感。
However, it had been found that even people insensitive to a certain smell at first can suddenly became sensitive to it when exposed to it often enough.
然而研究发现尽管人们起初对特定的气味不敏感，但经过长时间在该气味下的曝露，人们也会对这种气味敏感。
However, it had been found that even people insensitive to a certain smell at first can suddenly became sensitive to it when exposed to it often enough.
