If you use the fixedcoefficient method or load in specific percentage then you need to be careful when these percentages change or if you add a particular company.
如果您使用固定系数方法或载入具体比例，那么当这些百分比变更或您添加了特定公司时您需要小心。

The experiments results show that this algorithm has a good robustness for the JPEG compression with the fixedcoefficient, and a good fragileness for the illegal manipulation.
实验证明该算法对固定系数的JPEG压缩有较好的鲁棒性，并对图像的恶意篡改有较好的脆弱性。

Rather, the coefficient ratios between certain basis function are kept fixed at predetermined value.
