缺憾,有长度吗?缺憾的长度是多长呢?普通人家会有这样的经历,某个要紧处要用一寸长的钉子,你搜索家中积累的五金杂件,什么螺丝图钉垫片一大堆,好不容易清出一枚钉子,一试,钉子太长;又探雷似的犁一遍过去,看中一枚,比一比,短了。再又地毯式地搜查,在笔筒或书架等平常比较冷清丧 What is the length of the defect? ​​How long is the length of the defect? ​​Ordinary people will have such experiences. One important point is to use an inch of nails. You search for the accumulated miscellaneous pieces of hardware in your home. Finally, a nail was cleared out. A nail was too long. The plow that looked like a mine was over and over, and one of the fancy ones was shorter than one. Rugby-style search again, penholders or bookshelves, etc.
