The contrastive research is fully conducted from Chapter Four to Chapter Six. Chapter Four studies negation in English and in Chinese at the lexical level, which can be further divided into three sublevels, namely, morpheme, word, and phrase. Chapter Five studies negative sentences, explicit negative form at the syntacticlevel. And the study covers the classification, syntactic feature, nonassertive/assertive items, scope/focus of negation, two important tendencies, and some common special negative sentences. Chapter Six focuses on the implied negative sentences in English. According 10 devices employed to achieve negation, implied negative sentences are divided into four categories, namely, implied negative sentences by grammatical devices, by semantic devices, by rhetorical devices, and by pragmatic devices.

Methods Peritoneal macrophages of guinea pigs were infected in vitro by three different Leptospira strains, the virulent Leptospira interrogans serovar Lai type strain Lai, the avirulent L. interrogans serovar Lai type strain IPAV, and the nonpathogenic L. biflexa serovar Patoc type strain PatocⅠ, respectively, and heat inactivated Staphylococcus epidermidis was added 0.5, 1.5, 3 and 6 h after infection and incubated for 30 min. The effect of Leptospira on the phagocytosis of macrophage was evaluated by the inactivated Staphylococcus epidermidis phagocytosis rate and phagocytosis index.

First, the proposed scheme uses contourlet transform to extract multidirectional and multiscale texture information, and then obtains the feature points invariant to the affine transformation from the low and middle directional subbands by Harris-Affine detector. Second, the feature regions are adaptively computed by the feature scale of the local structure and normalized by U transform. The watermarking is embedded adaptively in those characteristic regions which are normalized. Finally, by vector quantization, several copies of the watermark are embedded into the no overlapped local feature regions in different directional subbands.
