1·Lastly, it is stressed that the defect of incomplete fusion has the greatest impact on the welding quality.

最后强调以未熔合缺陷对焊接质量影响最大。

2·C,. Incomplete fusion prevent adopting greater welding current, use correctly to weld the cleaning of operating, notice groove position.

未熔合的防止采用较大的焊接电流，正确地进行施焊操作，注意坡口部位的清洁。

3·The weld defects of incomplete fusion and burn through always occur when the electro-slag welding is used between the outside thin metal plate and the inner clapboard in a box-section member.

箱形截面构件薄壁板与内隔板电渣焊接时，易产生壁板烧穿和焊缝未熔合现象。

4·Aiming at the fuzzy and incomplete nature of fault characteristics of axial piston pump, a method of Bayesian networks and multi-characteristic information fusion was proposed.

针对轴向柱塞泵故障特征的模糊性和不完备性特点，提出一种多特征信息融合与贝叶斯网络相结合的故障诊断方法。
