金川河水BOD_5与COD_(Cr)的关系

RELATIONSHIP BETWEEN BOD_5 AND COD_(Cr)OF WATER IN JINCHUAN RIVER

同步测定了金川河上不同河段河水的 CODCr(x)与 BOD5 (y) ,通过回归分析 ,发现这两种数值之间存在着线性关系 ,即 :y=0 .6 6 8x- 11.

BOD\-5 and COD\-\{Cr\} of the water in Jinchuan river, a majar waterway through Nanjing city, were detected. The relationship between BOD\-5( y ) and COD\-\{Cr\}( x ) was identified and found out as linear below: y=0.668x -\{11.1.\}
