求翻译：由SEM图可以看出水热法制备的V2O5呈不均匀的棒状结构，凝胶法制备的V2O5呈不均匀的片状结构，直接热分解的呈不均匀的块状结构，柠檬酸分散后的V2O5粒径变小片层状态更明显，因此柠檬酸分散后的V2O5在效率测试中表现的效率较高。是什么意思？

As can be seen by the SEM water hot backup of the rule of law is not uniform V2O5 rod-like structures, the rule of the gel V2O5 is uneven chip structure, direct the thermal decomposition is uneven block structure, citric acid decentralized particle size smaller slice V2O5 level state more obvious, a

By the SEM chart may look the water leakage hot process preparation V2O5 assumes the non-uniform clavate structure, V2O5 which the gelatin legal system prepares assumes the non-uniform sheet structure, the direct thermal decomposition assumes the non-uniform massive structure, the citric acid disper

By SEM hydrothermal preparation here you can see that the V2O5 is uneven bar, gel preparation of V2O5 is uneven-like structure, direct thermal decomposition of non-uniform block structure, V2O5 size piece of citric acid dispersed layer status is more obvious, citrate dispersed V2O5 performances in t
