该模型基于回归分析、时间价值原理与重力分布原理预测交通量建立。
This traffic demand forecast model is established based on regression analysis, time value model and gravity distribution theory.
当高功率的弧是埋弧类型，通量粉末覆盖焊缝金属池还必须支持对重力的影响。
When the higher power arc is of the submerged arc type, the flux powder covering the weld metal pool must also be supported against the effects of gravity.
