At solder joints , different materials are brought into contact , and there are compositional gradients at the interfaces 不同的材料在焊点相互接触，因此在界面处会存在著组成之浓度梯度。
To overcome such drawback , the current cycle for every fused spot is controlled by the preset parameters in this machine 本设备采用逐点预置的方式，每个焊点的电流周波数都可单独调节设定。
The result of experiment shows that the algorithms are effective , and abundant features information is extracted 实验表明,引入的焊点图像特征提取方法是较为有效的,提取了较好的焊点特征向量。
The did the same with the back part of the body . i connected these two parts , creating new polygons between them 后半身的建模方法也是一样的，没什么特别。等都做完以后，再把两部分用焊点缝和起来并做一些细微的调整。
Even in the practical application involving ambiguous solders , the recognition rate of the proposed method remains as high as 95 . 16 % 并且在无法避免此类焊点的实际应用场合里，本论文所提之分类法则仍有95 . 16 %的辨识率。
