铁艺毛巾架会生锈吗

五个铁环的周长之和是
2πr1+2πr2+2πr3+2πr4+2πr5
=2π(r1+r2+r3+r4+r5)
=2πAB/2
=πAB
=100π(cm)

不锈钢门窗多是用201不大可能用304,304比201要贵的.做不锈钢钢要用氩弧焊机,切割机、角磨机、安装门窗时还要用到电锤（又叫冲击钻）等工具.

看直径做多大的楼梯了,一般室内小空间都是做80CM左右的梯面,因为旋转楼梯是扇形的梯面,内角不好走,太窄的话容易出事故,是按楼层高度计算的,和梯口面积多大,不够的叫房主找人敲大些,比如楼层高度是3M的,大约是13-15步左右,高度可以在18-25左右,制作的时候先在画好一个圆,然后分成你需要的步数,多少步就分多少格,这个分好的扇形就是楼梯面了,当然铁板是方形的,要节省材料,你可以先把这个扇形拿纸皮,或者其它的东西剪下来做样,好了,样也出了,那下一步做的是把下好的梯面料拿到先焊接垂直的立柱上,从下往上焊接,注意每一步都需要上下对垂直,不可以偏差太大,高度也要把准了,一般我们制作的第一步是和最顶部是相反的方向的,注意哦,不然到最顶部,你会做不去的,到了顶部,最后一级的话如若有偏差的话,你可以把休息台扩宽,这个是本人实际制作的经验哦,做过N跑楼梯了,就是这样制作的

有一个比较麻烦的办法.
倾斜着沿路径拉伸成三维的,而后截取你需要的那个平面.可能截取下来是一个“块参照”,然后再还原到平面的.

应该是盐酸,磷酸成本太高了,另外除锈也很慢.用磷酸桶来装而已.
你讲的泡盐水应该是亚硝酸钠水溶液或碱液,主要起防锈作用.
