所谓有标记主位(marked theme),即一个句子的主位不由逻辑主语充当,而是由句子的其它成分充当。如: (1)Little we see in nature that isours. 从语义——句法角度看,有标记主位是一种倒装,"是一种调整语义核心的方法"(秦秀白...所谓有标记主位(marked theme),即一个句子的主位不由逻辑主语充当,而是由句子的其它成分充当。如: (1)Little we see in nature that isours. 从语义——句法角度看,有标记主位是一种倒装,"是一种调整语义核心的方法"(秦秀白1988:77)。与此有关的文体学认为这是一种句法变异(syntactic deviation),具有突出语义、增强表达效果和艺术感染力的作用。而从语篇角度看,它具有承上启下和进一步扩展语篇的功能(Brown & Yule1987:133)。汉语中也存在着这种有标记主位。如:展开更多

We consider excitations from the 3p, 3d, and 4s subshells. The effects of the strong 3p→ 3d and 3p→ 4s transitions are included as resonant contributions to the total cross sections. Good agreement with experiment is found.展开更多

Lett. 107 （2011） 083601]. For small loss of photons, we find that the entangled coherent state can surpass the Heisenberg limit.
