转换主项 P=q(r-1)+2r [r] a=krl+2kr^2 [l]P=q(r-1)+2r [r] r=?a=krl+2kr^2 [l]l=?
转换主项 P=q(r-1)+2r [r] a=krl+2kr^2 [l]
P=q(r-1)+2r [r]
r=?
a=krl+2kr^2 [l]
l=?

转换主项 P=q(r-1)+2r [r] a=krl+2kr^2 [l]P=q(r-1)+2r [r] r=?a=krl+2kr^2 [l]l=?
P=q(r-1)+2r [r]
P=qr-q+2r*r
P+q=qr+2r*r
P+q=r(q+2r)
(P+q)/(q+2r)=r
转换主项 r=(P+q)/(q+2r)
a=krl+2kr^2 [l]
a=krl + 2kr^2*l
a=l(kr + 2kr^2)
a/(kr + 2kr^2)=l
a/k(r+2r^2)=l
