1.It is? feasible to replace lap welding with butt welding to improve quality of mid?diameter spiral weld pipe?In this paper,cone?cylinder?mandrel forming and horizontal roll extruding technology for butt welding is reported??φ219 mm×7 mm pipe has been produced successfully?Test results show that butt welding can be used in production of spiral weld pipe???
用高频对接焊代替高频搭接焊是提高中直径螺旋焊管质量的可靠途径。 本文将锥度芯棒成型、平辊挤压技术用于高频对接焊工业试验中，成功地生产了?219mm×7mm焊管，并对试制管进行了检验。
2.The results show that the new butt joint approach can obtain smoother butt joint interface and greatly improve the coupling efficiency and slope quantum efficiency of EML chips from 17% to 78% and from 0 03mW/mA to 0 15mW/mA,respectively.
实验结果表明 ,这种对接生长方案 ,可以获得光滑的对接界面 ,显著提高了激光器和调制器之间的耦合效率 (从常规的 17%提高到 78% )及EML器件的外量子效率 (从 0 0 3mW /mA提高到 0 15mW /mA) .
