Motivated by the underdeterminacy thesis that natural-language sentences do not fully encode the propositions they are used to express, the thesis discusses explicature in utterance interpretation from the perspective of cognitive pragmatics.

The present paper attempts to explore the relationship between explicature derivation and conceptual mappings from the following three aspects:metaphoric mappings,metonymic mappings and interaction between metaphor and metonymy.

Study of distribution and antisense imaging for ~(99m)Tc-ASON-EGF in breast cancer-bearing nude mouse models;

Current researches and prospective of radiolabeled antisense imaging in tumor;

With the further research of antisense imaging, N-hydroxysuccinimidyl S-acetylmercap to acetyltriglycline(S-acetyl-NHS-MAG_3) as a novel bifunctional chelator is interested by scientists and used widely.

And metaphors can play a role in the stipulations of the explicit meanings of the utterances.

This thesis approves the " Graded Salience Hypothesis" suggested by Rachel Giora,explains the forms of "salience of sense",and then provides cognitive evidence for the sense salience of figurative language.

The reading process combines the visionary interpretation; it appears to take the language code and iconic code as organic parts, so it has a good value for creating the meaning manifestation during the process of the aesthetic subject reading.

The present paper discusses the correlation between schema theory and discourse comprehension,which is classified into three aspects:information processing pattern of schema theory,meaning manifestation set up by schemata and cognitive inference educed from schemata.
