Taking a seven floors UPVC drainage experimental equipment as the study object,the vertical distance between the lowest horizontal branch and building drain pipe was measured.
以7层UPVC排水试验装置为研究对象,对最低横支管与排出管(立管连接处距排水立管管底)的垂直距离进行了测定。
To prove the uniqueness and the property of the lowest degee about u(x)and v(x)by algorithm of division in the greatest common factor expression d(x)=u(x)f(x)+v(x)g(x).
对最大公因式的表达式d(x)=u(x)f(x)+v(x)g(x)中用辗转相除法所得出的u(x)和v(x)所具有的唯一性和次数最低性进行一下证明。
