In addition, the sensitivity of this method was close to that using traditional microtitration plates as carriers. However, the assay was much faster (the assay time decreased from 100—120 to 30 min).

此外，灵敏度与用传统微孔板做载体相似，但测定时间更快（从100-120分钟减少到30分钟）。

It's four o'clock now, one minuter not much and one minute not less.

正好是四点，一分钟不多，一分钟也不少。

And we find out that the stability of generate NAIs by imitate pulsed corona is much better than continued discharging. If we close the electric field for 30sec and restart it for 1 minutes.

关闭电场30sec后再重新开启电场一分钟的方式可让空气负离子浓度维持在4.0×105 ions/cm3以上超过30分钟。

It is suggested that Ginaton may improve the microcirculation of the xenografts and lighten the HAR. The PVBF after FK506 pretreatment were 0.466±0.049, 0.399±0.037, 0.358± 0.040, 0.317±0.039 and 0.258±0.033kHz, the survival time was 215. 9±16. 0min, significantly higher and longer than those of the nontreatment recipients.

发现移植前30分钟应用金纳多移植后0、15、30、45和60分钟多普勒超声测得的移植肝PVBF波幅分别为0.406±0.020、0.357±0.025、0.308±0.013、0.249±0.019和0.205±0.014kHz，与未用药组相比其降低的程度有明显降低，说明金纳多具有改善豚鼠至大鼠移植肝的微循环，具有减轻排斥反应的作用。

This stage is usually brief, averaging 20 minutes for parous women and 50 minutes for nulliparous women.

这一阶段通常较短暂，经产妇平均20分钟，初产妇平均50分钟。

Lucic missed another golden chance minutes later. He got behind the defence on a counterattack but hit his shot off the chest of the onrushing Seaman (65').

几分钟后，卢斯奇又错失了一次黄金机会，他在对方后卫身后得到反击传球，不过他的射门打在了猛冲上来的西曼的胸膛上（第65分钟）。

No significant difference was found in the sex, gestational age, birth weight, type of delivery, one minute and five minutes Apgar scores, inborn or outborn, time of intermittent positive pressure ventilation started, serum sodium level, grading of chest X-ray findings or lung volume between the two groups.

比较这两组，发现在性别、怀孕周数、出生体重、生产方式、1分钟及5分钟Apgar分数、院内生产或院外转送、何时开始呼吸器治疗、血清钠离子浓度、胸部X光分级及肺体积方面并无差异。

The total playing duration of Toofan is 20 minutes with five stages of complexity while total playing duration of Sarak Paar is 15 minutes.

总播放时间的风暴是20分钟，分为五个阶段的复杂性，而总播放时间的Sarak Paar是15分钟。

"This study shows the mechanism that suppresses muscles twitches in REM sleep and this will lead to better treatments and potential cures for this disorder," says Peever.

行为可持续几秒钟到数分钟，发生的时间多在入睡90分钟后和睡眠近结束时。患者常采用一些自我保护的方法。

In order to check the corresponding compound at 31P NMR –45.4 ppm, stable pentacoordinate spirobicyclic 2-phenoxy-1,3-phenylene-dioxo-1,3,2-iminoacetoxyphosphoranes were synthesized through a new and efficient method whereby phosphorus pentachloride was displaced stepwise by catechol, N,O-bisamino acid and phenol, or catechol, phenol and N,O-bisamino acid, their 31P NMR chemical shifts are at about 31P NMR –45.0 ppm, the results showed that the compound 4 at 31P NMR –45.4 ppm was pentacoordinate phosphorane containing amino acid residue.

采用磷谱跟踪来研究上述成肽反应机理。例如在氮气保护下，0.1mmol O，O-亚苯基磷酰氯（1）和0.15mmol N，O-二苯丙氨酸（2）苯溶液加入0.6ml核磁管中，混合均匀，反应过程用磷谱检测。反应1分钟后，起始原料1(δp=19ppm)很快转变成N-磷酰苯丙氨酸的三甲基硅基酯（3）(δp=19.8ppm)，在8分钟内，3完全转变成苯丙氨酸磷烷4(δp =-45.4ppm)，同时出现环磷三酯（6）(δp=3.5ppm)。随着反应的进行，对应于化合物4的峰逐渐变小，而6逐渐变大。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
