Acidic Effect Coefficient的用法和样例：
- The correlation between water and soil conservation effect coefficient and the primary vegetation potentiality was positive.
- The correlation between water and soil conservation effect coefficient and the difference between precipitation and evapotranspiration was negative.
- The orthogonality experiment showed that temperature and the content of citric acid effect markedly for extruding the SDF content of extruding oats bran.
- In present work, the acid effect in radiation-induced grafting of N-vinyl-pyrrolidone N-VP or 4-vinyl pyridine (4-VP) onto silicone rubber was inves-tigated.
