扫时间

通过对分流排空量、吹扫时间、PTV温度及其进样体积等PTV参数的优化，提高了检测灵敏度。

Split vent flow , purge time , PTV system temperature , and maximum sample volume were optimized . In comparison with conventional methods , the detection limits were improved by one order of magnitude .

当减小样品室体积以后，光谱强度随采谱次数增大迅速趋于平稳，也缩短了样品沉积物的吹扫时间，但是光谱信号的波动性明显变大了。

After the volume of the sample chamber was reduced , the spectral intensity quickly tended to be stable with the increase of the acquisition spectrum number . The washing time of samples sediment was shortened .

此外，吹扫末期时间将需要做细小调整。

Furthermore , venting ending time may require slight readjustment .

其还提供很多软件功能的参数设定，如：后吹扫的时间等可由操作人员就地设定。

The parameters of many software functions , such as e.g.a final ventilation period , can be set by the operating personnel on site .

通过实验研究得出对拉丝污染起决定性作用的主要因素是沥青灌装控制阀座上的吹气孔数量、密封带宽度、越程槽的形状以及气孔通气吹扫的时间。

Through experiments , we know that the key factors causing thread pulling pollution are the number of air holes on the controlling value of asphalt filling machine , the width of sealing belt , the shape of over slot and the blowing time of air holes .

现场试验表明，采用复合胶塞固井能够确保碰压，缩短水泥塞，从而减少了扫水泥塞时间（由过去的平均50h缩短到现在的不到10h），而且改善了固井质量。

Field tests show that a complex plug ensures cement to be displaced in place , shortens cement plug , and reduces time of drilling out of it from 50h to less than 10h , and improves cementing quality .

在上海激光联合实验室的20TW激光器上对X光条纹相机的扫速、时间分辨等时间性能进行了标定，取得了较好的结果。

The temporal characteristics of the X-ray streak camera , such as sweep speed and temporal resolution , were calibrated for the first time on the 20 TW laser facility at High Power Laser and Physics Joint Laboratory in Shanghai .

提出采取严格控制扫线作业时间和扫线蒸汽流量，增大油气空间的体积和增加罐顶通气孔数量和面积等措施，可有效地预防该类事故的发生。

The measures to control the vapor purging time and flow rate of vapour , enlarge the oil-gas space and increase the number of air hole as well as venting area are given , which can effectively prevent the tank top from cracking .
