灵敏

By analyzing the escape of X-ray and Auger electron generated by 37Ar, wall effect of internal gas proportional counter in 37Ar activity measurement was studied theoretically. Escape of X-ray is the main reason for wall effect of internal gas proportional counter in 37Ar activity measurement.

通过分析37Ar衰变产生的X射线和俄歇电子在内充气正比计数管灵敏体积中的逃逸及计数管在37Ar活度测量中的壁效应，得出X射线在正比计数管中的逃逸是产生壁效应的主要原因，提出了压力指数外推方法。

By analyzing the escape of X-ray and Auger electron generated by 37Ar, wall effect of internal gas proportional counter in 37Ar activity measurement was studied theoretically. Escape of X-ray is the main reason for wall effect of internal gas proportional counter in 37Ar activity measurement. Thus, the exponential extrapolation method of pressure was proved correctly.

Cells within plant or animal respond to stimuli less obviously than single-celled protist. But they respond.

动植物细胞与单细胞的原生生物相比，前者对于一些微妙的刺激反应更加灵敏。

The highly sensitive chromogenic reaction of a ternary complex of 4-(2-benzothiazolylazo) pyrocatechol with Mo-, W-diphenyl guanidine and the application of partial least squares method in simultaneous spectrophotometric determination of trace Mo and W have been studied.

本文研究了新显色剂4-(2-苯并噻唑偶氮)邻苯二酚-Mo、W-二苯胍三元配合物的高灵敏显色反应以及偏最小二乘法在同时分光光度测定痕量钼和钨中的应用。

A novel catalytic resonance light scattering method for the determination of traces of formaldehyde in blood plasma was developed. It was based on the fact that potassium bromate reacted with pyronine Y to form association nanoparticles which gave stronger resonance light scattering effect, and formaldehyde can catalyze potassium bromate oxidizing pyronine Y resulting in decreasing of the intensity of resonance light scattering in sulfuric acid.

在稀硫酸介质中，溴酸钾与吡啰红Y能聚集成较大粒径的纳米微粒而使共振光散射增强，而甲醛能催化溴酸钾氧化吡啰红Y而导致体系共振光散射减弱，据此建立了一种灵敏、简单、快速测定血浆中痕量甲醛的新方法。

The technique is so sensitive that it can detect a single radioactive carbon atom hiding among a quadrillion ordinary ones.

这种技术是如此的灵敏以至于可以在百万的四次方个原子中找到某一个放射性碳原子。

But people are often reproached for unpunctuality when their only fault is cutting things fine. It is hard for energetic, quick-minded people to waste time, so they are often tempted to finish a job before setting out to keep an appointment.

但有些人不准时经常因为掐钟点所致，他们经常受到责备，精力充沛、头脑灵敏的人极不愿意浪费时间，因此他们常想做完一件事后再去赴约。

The quick-thinking captain managed to ground it on a reef, allowing all but two of its officers and men to wade ashore.

脑筋灵敏的船长设法将船搁浅在礁石上，因此除了两名船员和几个人之外，大部份的人得已涉水上岸。

And this dramatic rescue was caught on tape. Quick-thinking police officers pulled an Indiana woman from her car just seconds before it explodes.

反应灵敏的警察从一辆即将爆炸的车里，把其印第安女车主拖拽出来，这一戏剧性的营救被监控录像记录了下来。

She gently rebuff ed him, but agreed that they could be friends
