请诸位看一下这段话是否有语法错误，如有不妥，请帮忙修改之，bb克开贴领追加。谢谢诸位帮忙，不胜感激，如有兴趣，交个朋友，。。。 Response surface methodology, based on Box–Behnken design, was used to optimize the ultrasonic extraction conditions of Flammulina velutipes polysaccharides (FVP). Four independent variables (ratio of water to raw material, ultrasonic power, ultrasonic time, and ultrasonic temperature) were considered. Statistical analysis of the experiment indicated that the quadratic model fitted for the extraction conditions of FVP was in good agreement with the experimental results. A yield of FVP of 39.215% was obtain under the modified conditions (ratio of water to material 24 mL/g, ultrasonic power of 410 W, ultrasonic time of 25 min, and ultrasonic temperature of 35°C). DPPH scavenging rate of 82.12% and AChE inhibitory rate of 18.51% obtained at 0.02g/mL in DPPH scavenging assay and AChE inhibitory activity test indicated a good potential of FVP to enhance cognitive ability. |

| 写得挺好的，只是做了一点儿小修改，论文一般多用一般现在时来说明现象和结论。Response surface methodology, based on Box–Behnken design, is used to optimize the ultrasonic extraction conditions of Flammulina velutipes polysaccharides (FVP).
