文献EIS谱图的分析没看懂，请大家赐教啊？文献：The aspolished samples showed a dramatic decrease of the impedance in the capacitive region, which is characteristic for the pitting process on steel. The polarization resistance of as-polished sample (Rp0) is 2.8 Ω. Subtracting this value from the Rp of Ni–P (RpNi–P?Rp0) results in 1.2 Ω. Increasing magnitude of the resistance of the barrier layer indicates better corrosion performance. In addition, the phase angle θ tended toward zero at low frequencies indicating that the resistance of the barrier layer was being approached. An additional maximum of θ was observed for Ni–P coated samples, as evident in Fig. 1B. These changes of the spectra at very low frequencies indicate the occurrence of pitting.1 请问capacitive region的范围是什么？ 2 为什么要RpNi–P?Rp0 ？polarization resistance 是由极化曲线得到还是阻抗谱得到？Increasing magnitude of the resistance of the barrier layer indicates better corrosion performance这句话的原理是什么？3 为什么在低频处θ接近零时候indicating that the resistance of the barrier layer was being approached？4 An additional maximum of θ was observed for Ni–P coated samples, as evident in Fig. 1B. These changes of the spectra at very low frequencies indicate the occurrence of pitting.这个是怎么得出的，可以详细说明一下吗？各位赐教啦！谢谢！问题有点多，呵呵12.png查看更多3个回答 . 13人已关注
求助MZmine的安装问题？请问哪位牛人前辈知道怎么正确安装MZmine软件，按手册里说的3. Edit the startup script in a text editor and adjust the parameters in the script (e.g. HEAP_SIZEor JAVA_COMMAND), if necessary. For integration with R you will need to correctlyconfigure the following:R_HOMEThis is the directory where R is installed, e.g. for Windows it will be something likeC:Program FilesRR-2.15.0.R_LIBS_USERThis is the directory in which R installs third-party packages. It's usually a subdirectoryof your personal directory, e.g. for Windows it will be something like%USERPROFILE%DocumentsRwin-library2.15.PATHAppend the directory that contains R's libraries. It will be a sub-directoryof %R_HOME%, e.g. for 32-bit Windows it will be something like%R_HOME%bini386 or for 64-bit Windows %R_HOME%binx64.JRI_LIB_PATHThis is the directory where rJava has installed its JRI libraries. It will bea sub-directory of %R_LIBS_USER%, e.g. for 32-bit Windows it will besomething like %R_LIBS_USER%rJavajrii386 or for 64-bit Windows%R_LIBS_USER%rJavajrix64.这一步具体怎么做啊？急求！！！！！万分感谢啊查看更多6个回答 . 10人已关注
