1.非封闭线路上的指数问题,主要可分为以下三种情形
(1)如果在非封闭线路的两端都要植树,那么:文章源自公式库网-https://www.gongshiku.com/html/201807/aoshuzhishuwentigongshi.html

(3)如果在非封闭线路的两端不要植树,那么:文章源自公式库网-https://www.gongshiku.com/html/201807/aoshuzhishuwentigongshi.html
株树=段数-1=全长÷株树-1
全长=株距×(株树+1)
株距=全长÷(株树+1)
2.封闭线路上的植树问题:
株树=段数=全长÷株距
全长=株距×株树
株距=全长÷株距
