求翻译：然后，对单供电臂带负载运行时，通过对单供电臂和动车组上电压量和电流量的分析和相应的仿真研究，从而更进一步的证明了单供电臂数学模型的正确性。是什么意思？

Then, run a single power supply with a load arm, the arm by a single power supply voltage and the EMU on the volume and amount of current analysis and corresponding simulation study to further prove that the mathematical model of a single power supply right arm sex.

When then, to list power supply armband load movement, through and moves on the vehicle crew to the list power supply arm the voltage quantity and the amperage analysis and the corresponding simulation research, thus the further has proven the list power supply arm mathematical model accuracy.

Then, on one load of feeding runs, through to single and multiple units of feeding amount of voltage and current analysis on and the corresponding simulation, thus further proof of the correctness of mathematic model of feeding.
