A detailed CO2 laser-MIG hybrid welding experiment was carried out on the 4mm mild plates to discuss the relation of laser power, arc current, the maximum welding speed and the weld shaping , as well as the joint gap.

对此，采用4mm厚Q235钢板进行了CO2激光-MIG复合焊接研究，探讨了激光功率、电弧电流对最大焊接速度的影响及其和接头间隙对焊缝成形的影响规律。

Purpose To investigate the clinicopathological feature, immunophenotype and genetic of anaplastic large cell lymphoma, sarcomatoid variant.

目的 探讨肉瘤样型间变性大细胞淋巴瘤临床病理特点、免疫表型及分子遗传学特征。
