tie-in

At present, direct and efficient detection methods are always lacking when it comes to the tie-in place of welding line in the metal structures, liquid hide area of dead angle of industrial facility container and some corrosion sensitive segments such as bolt and screw.

目前，对容易遭受腐蚀的金属设备构筑物的焊缝接头处、工业设备容器的死角液体滞流区、螺栓螺纹等腐蚀敏感部位往往缺乏直接有效的检测手段。

The control system of special cutting machine for the of electrode tie-in produce line, combined with machine and electricity and hydraulics was introduced.

介绍了电极接头生产线中的切断专机的机、电、液相结合的控制方法。

In addition, engineering experimental data fitting system was used to get the tie-in equation between tray efficiency and F-factor. Some critical data that was hard to achieve in experiment were ob to obtained.

此外，本文还运用工程实验数据拟合系统对塔板效率进行了数据拟合，得到了塔板效率与阀孔动能因子关联方程，获取了现有条件下实验无法测得的关键性数据。
