模型驱动表现具有一个域不变模式：它足够普通，可表示任何持久化类型。
A model-driven representation has a domain-invariant schema: it is generic enough to express any persistent type.
在模型驱动表现中，Actor的模式是不变的，而在域驱动表现中，它是会变化的。
In the model-driven representation, the schema for Actor does not vary, whereas for a domain-driven representation, it does.
结果表明，将小波域上的经验维纳滤波器与平移不变小波相结合进行去噪，所得到的效果是最佳的。
From the experiments and analysis carried out in the paper, the optimal denoising results can be obtained by the combination of the empirical Wiener filter and the translation invariant wavelet.
小波变换不具有几何不变性，因此，小波域水印对抗几何攻击是一个十分困难和富有挑战性的课题。
The wavelet transform has no ability to resist to geometric distortion, so the wavelet domain watermarking resisting to geometric distortion is a very difficult and challenging subject.
基于这个不变的数字特征，本文提出了种基于图像DCT域的鲁棒性水印和脆弱性水印共存的双水印算法。
Based on this, the paper proposes a double watermarking algorithm based on DCT domain that the coexistence of robust and fragile digital watermarking can be achieved.
第四章在有限典型群的极大子群和根子群的有理不变式域方面做了一些讨论。
