可以通过“SOC 和初始电荷分布 1”节点中的“方程”理解变量comp1.liion.Q_cell_init的计算过程，也可以通过帮助文档查看该变量的详细计算公式，参考连接内“CELL CAPACITY AND STATE OF CHARGE”部分的说明：https://doc.comsol.com/6.2/docserver/#!/com.comsol.help.battery/battery_ug_electrochem_battery.06.56.html%23772830

张俊你好，推导过程其实就是按照SOLneg和SOLpos的恒等式以及Yi来推导的，比如SOLneg=QLi,neg/Qhost,pos=(QLi,neg/Qcell)/(Qhost,neg/Qcell)=SOC/Yhost,neg，因为SOC是根据负极的嵌锂量计算的，所以SOC=QLi,neg/Qcell成立，Yhost,neg则根据Yi的定义。按照同样的思路也可得SOLpos。
