Abstract: Character analysis of military terms can reflect the composition and laws of character application in military field. Based on the quantitative investigation on the 2011 edition Military Terms of PLA, we found that the characters of military terms are commonly used Chinese characters, which means that military terms are basically in accordance with the simple principle for name. Compare with the 1972, 1982, 1997 edition Military Terms of PLA, we can see that the coverage of characters is gradually expanding,while the common characters are relatively fixed, and the distribution of the critical characters is imbalanced.

Key words: military terms, Chinese character, common character, the critical character
