As a bonus, in researching this little factoid I discovered a new word I hadn't known before; kerf. When you cut up a log into boards the thickness of your saw matters.
我在查询这个小词的时候，额外地发现了一个我以前不知道的新词：kerf .当你要把一根原木切割成一块块木板时，你的锯的厚度很关键。
The wire sawing process has been applied to slice single silicon into thin wafers for its character of minimum warp, uniform thickness and low kerf loss.
由于线锯切割具有切片薄、表面翘曲变形小、厚薄均匀和切口损失小等优点，被广泛用于单晶硅切片加工。
