例句
- This superior reliability comes from advances in packaging techniques and epitaxial structure, together with the use of hard solder construction.
这种超级可靠性来自于封装技术和外延结构的发展，也得益于硬焊接架构的使用。 - 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，没有修整或清理毛刺的管道端口以及管道坑的存在，或者流体的突然转向，都可能产生导致局部高流速的原因。
