这张图像显示出银河系似一个明亮的横带，经由其中心与冷尘埃的飘带相连，并向其上方和下方延伸。

The image shows the Milky Way as a bright, horizontal band through the centre with "streamers" of cold dust extending above and below.

接头延伸率的改善同热影响区冷变形程度的减弱及焊缝强度、应力水平同母材趋于一致有很大关系。

Improvement of elongation of joint is related to weaker cool deformation degree of heat affect zone (HAZ) and uniformity of strength and stress level between weld and base metal.
