| Abstract: | Three kinds of indicator influence on fatty acid value and terminal pH in titration was researched by statistical analysis of variance and T test for 25 copies of rice. The results indicated that the three kinds of indicator influence on fatty acid value and terminal pH in titration was significant. It was very important to select indicator for test results. |
