作者通过长期实践探索,提出以下确定维修费的经验公式:x=(F_j·x_1+F_D·x_2)·a_1·a_2·a_3·a_4式中x—维修费用值(单位:元);F_j、F_D—分别为设备机械和电气复杂系数;x_1、x_2—分别为单位复杂系数维修费(单位为
Through long-term practical exploration, the author puts forward the following empirical formula for determining maintenance costs: x = (F_j · x_1 + F_D · x_2) · a_1 · a_2 · a_3 · a_4 where x-maintenance cost (unit: yuan); F_j, F_D - Equipment mechanical and electrical complex coefficient respectively; x_1, x_2- are unit complex coefficient maintenance fee respectively
