如题,审稿人提到的问题:(2)The charge behavior of PDAEMA can also be accurately simulated using software such as Malvern. The authors might consider conducting a brief simulation to better illustrate the protonation and deprotonation states of the molecule under different pH conditions. 不明白Malvern是模拟软件还是要求我们对样品进一步测试,请各位大佬们指教
