| 1. | Design of fixture for jointing downcomer hard pipe of mazida automobile 马自达下水硬管焊接夹具的设计 |
| 2. | The optimization of segmental downcomer of the ctst tray was also studied 实验还对ctst塔板弓形降液管的优化进行了初步研究。 |
| 3. | Material receiving inspection number and steel grade shall be stamped on the heads , shells and downcomer nozzles 封头、筒体和集中下降管管座上必须打上工厂的材料检验编号和钢号。 |
| 4. | In moist season , millipede would in vade your home from downcomer and green belt around home . swarm millipedes would let you feel thrillingness 在潮湿的季节,千足虫会从下水道和绿化地带向您的工作、生活空间侵入,成群成片的数量会使您感到毛骨悚然。 |
| 5. | In a transparent plexiglas column with inner diameter of 600mm , the comparison of downcomer capacities between ctst tray and fl valve tray were studied with the air - water and foaming systems 在600mm的透明有机玻璃塔中,采用空气?水和易发泡物系,对两种塔板的降液管操作能力进行了比较研究。 |
| 6. | By transformation of the downcomer of the claus gas separator , methanol entrainment by claus gas is eliminated , the oil content in the methanol in the system reduced , and good economic benefit obtained 对克劳斯气分离器降液管改造后,消除了克劳斯气夹带甲醇的现象,降低了系统甲醇中的油含量,取得了较好的经济效益。 |
| 7. | Or , if have the same operation loads , the downcomer size of ctst tray can be designed smaller than the fl valve tray . it was found that ctst plates have bigger operating capabilities than other traditional plates in coping with foaming systems 总之,在处理两种物系,尤其是易发泡物系时, ctst与f1浮阀等传统塔板比较,其降液管操作能力大得多。 |
| 8. | The residence time of distribution and froth height in the downcomer were measured . the tracer used was 10 wt % sodium chloride solution . the residence time of distribution curves in a downcomer were measured by using the tracer technique 所用示踪剂是10 (质量百分比)的nacl溶液, rtd曲线采用了脉冲响应技术来测量,用计算机实时采集系统对数据进行采集。 |
| 9. | The dispersion model , with axial dispersion only was used to describe the liquid flow in the downcomer . the model parameters were fitted by the least - squares method . it was found that the curve of dispersion model fitted the experimental rtd curve well 本文利用一维轴向扩散模型对降液管中液体流动进行了数学描述,用时间域最小二乘法拟合了模型参数,模型方程所作曲线与rtd曲线吻合较好。 |
| 10. | In addition , the hf in the downcomer of ctst plate is 110 ~ 150mm lower than that of fl valve plate . it was showed that making a comparison of two plates , the downcomer of ctst tray can cope with more operation loads with the same size downcomers 这说明相同大小的降液管, ctst塔板上的降液管可处理的操作负荷比浮阀塔板的要大;即若在相同的操作负荷下,在设计降液管时, ctst塔板的降液管尺寸可比浮阀塔板的小。 |
