After our test with 175 samples in junior high school, and finish these researches step by step, we get the following conclusions: 1.The percentage score fuzzy linguistic scale's reliability is 0.722, the brace score scale 's reliability is 0.776, the brace score scale's reliability is better than the percentage score fuzzy linguistic scale. 2. The percentage score fuzzy linguistic scale's accumulation explanation is 53.632%, and the brace score scale 's accumulation explanation is 53.592%, the difference between this two scale is really small. 3.The paired-samples T test's result of test time and score are both significant, it means the brace score scale 's test time is obvious shorter then percentage score fuzzy linguistic scale, and there scores have obviously difference. 4.For IPA, the brace score scale 's average variance is 0.25, higher than the percentage score fuzzy linguistic scale's 0.12, it means the brace score scale can get more samples' degree of importance. 5.The brace score scale 's discard scale ratio is 7.53%, lower then the percentage score fuzzy linguistic scale's 19.25%.
