列入表8的资料证明,采用经过综合修理的P65型钢轨最有利:对通过1Mt货运量的钢轨,其消耗的金属价值比采用P50型新钢轨所消耗的金属价值小,后者是前者的1.4～1.8倍 (以旧钢轨在比较次要线路上采用的条件进行比较)。
The data listed in Table 8 demonstrate that it is most advantageous to use a fully repaired P65 rail: the value of the metal consumed for a rail passing 1Mt is less than the value of the metal consumed for a P50 new rail, the former being 1.4 ~ 1.8 times (to compare the conditions used in the old rail compared to the secondary line).
