How to realize zero oil loss is discussed.
就加油站实现"零"损耗问题进行了探讨,分析了油品在进、销、存各个环节可能出现的损耗,提出了具体措施:要严格进货验收,计量准确;加强设备巡检,避免非正常损耗;加强计量器具管理和计量员培训,完善加油站油品损耗补偿制度。
The main factor causing changes of oil transportation costs is the expenditures of oil and power loss.
影响输油成本变化的主要因素是油电损耗费用,文献[3]利用灰色系统理论,以输油管线每年的输量、相应的电耗和油耗为时间序列,建立了三元素非等间距GM(1,1)模型来预测管线油电损耗,但是其结果精度并不高,而且计算复杂,油损耗预测的相对误差范围是0。
Based on the theoretical analysis of tank loss,this paper analyses and calculates the tank loss in a main transformer of AC-DC--AC electric locomotive with finite element method(FEM), and tables a better proposal for shielding.
基于油箱损耗的理论分析，采用有限元方法，分析和计算一台交流传动电力机车主变压器的油箱损耗，提出更好的屏蔽措施。
