查询词典 holdup

The experimental setup is designed to measure the change of dynamic holdup during the course of non-reflux period and the calculation value is consistent with the experimental results, which indicates that the downflow velocity of dynamic holdup becomes smaller with the decrease of dynamic holdup in the column during the course of non-reflux period.

本文设计了测定无回流过程中动持液量变化的实验装置，在与动态液相交换的全回流间歇精馏串联实验相同的条件下测定了无回流阶段的动持液量变化，模型计算值与实验值比较吻合，结果表明在无回流过程中随着精馏塔中动持液量越来越少，动持液向下流动速度也越来越小。

It was also found that R increases with accumulator and condenser holdup. Further studies on the dynamic role of column holdup showed that the ratio of column holdup to reboiler initial charge acts as a factor.

对塔内持液的动态作用规律的深入研究表明：持液量与釜液量之比为一个因子，因此对于一个确定的分批精馏塔，当q0.7时，存在最佳投料量。

Axial distribution of gas holdup;inflection point of gas holdup;frother dosage

气含率轴向分布；气含率拐点；起泡剂用量

As the foaming agent is the continued increase in frother dosage of 400g / t, the gas holdup appears the phenomenon of axial turning point was not obvious, the axial distribution of gas holdup tends to uniform.

随着起泡剂用量的继续增加，在起泡剂用量为400g/t时，气含率出现轴向拐点现象不明显，气含率轴向分布趋于均匀。

If the average slip velocity is zero, there is no holdup of one phase relative to the other.

如果平均滑移速度为0，也就没有一相对另一相的滞留。

On the basis of introducing the working principle and characters of newly made Gas Holdup Tool, the usage of GHT in detecting the gas well production performance is analyzed. Methods are provided for analyzing fluid property, flow status and judging water carriage in gas wells by integrating the logging data obtained from traditional densimeter and the new GHT. Based on the characters of different depth in water carried gas wells, a model is established for interpreting the water-carried gas wells.

在介绍新的持气率计测量原理和特点的基础上，分析了持气率计在气井生产动态监测中主要用途，提出了综合传统密度计和新型持气率计测井资料分析井下流体性质、流动状况及判断气井载水的方法；根据载水气井不同深度段的特点，提出了载水气井的解释模型。

This level, just above the distributor and eductor in the column (Figure 1), is part of a mixing zone, and apparently shows an anomalous lower holdup profile than the 78 cm level.

图3b表示柱中部四个位置的固体流速的时间平均化轴向成分也有相同的定量结果。

The influence of magnetic field intensity on bed structure, pressure drop, minimum fluidization velocity, transition velocity, and liquid holdup were investigated.

试验结果表明，固含率轴向分布基本均匀，径向为"扁-陡曲线"分布。固含率随磁场强度和颗粒尺寸的增大而增大，随液体粘度和空塔液速的增大而减小。

Although batch distillation has been dealt with more than 100 years, the design methods developed to date have some disadvantages, most of which are derived from FUG method for continuous distillation or from experiences under the assumption of no holdup and no slop cuts.

多组元分批精馏过程和设计方法的研究分批精馏

All the evidence shows that he is innocent of the holdup.

所有这些证据表明他是无辜的，没有参与那次抢劫。

Chinese traditional virtue is humility and wariness,the compliment and praise to the others should be declination

中国人的传统美德是谦虚谨慎，对别人的恭维和夸奖应是推辞。如

We bought this house on the never-never.

我们以分期付款的方式买下这座房子。
