The research of controlled usage factors on influence degree to the productivity of little tonnage truck ' s transportation 可控使用因素對小噸位貨車運輸生產率影響程度的研究
The result indicates , due to the increment of porosity and strength , and the enlargement of pore diameter and the decrement of the resistance of zn electrode made by casting , the usage factor of the active material of zn electrode and the capacity in factor of the zn electrode were increased 指出:由于采用鑄造法可提高電極的孔隙率、強度、增大電極的孔徑、降低電極的內阻,從而使得電極的活性物質利用率,電極的實際比容量得以極大的提高。
