例句
- This superior reliability comes from advances in packaging techniques and epitaxial structure, together with the use of hard solder construction.
這種超級可靠性來自於封裝技術和外延結構的發展，也得益於硬焊接架構的使用。 - The presence of a dent, tube ends which are not reamed or deburred before soldering, and sudden changes in direction can all cause localized high velocity conditions.
在焊料焊接之前，沒有修整或清理毛刺的管道埠以及管道坑的存在，或者流體的突然轉向，都可能產生導致局部高流速的原因。
