所采用的U型管式反应器基本实现床层内等温操作，用于筛选新型颗粒催化剂有较强的可比性。
The U tubular reactor employed in this reaction practically achieves isothermal operation inside the bed, and presents good comparable results in screening new catalyst.
校正后的反应器可分别进行等温操作、绝热操作以及等温和绝热的混合操作，拓宽了仪器适用范围。
As a result, the calibrated reactor could be employed to isothermal operation, adiabatic operation and isothermal-adiabatic operation, which widened the use range of the apparatus.
指出在管输油品、线路走向及输量等已定时，影响等温输油管道总费用的主要因素有管材、管径及操作压力。
Once the throughput, pipeline route and oil kinds are defined, the main factors, which influence the total cost of isothermal oil pipeline, are material, diameter and design pressure.
