In detail, the noun-centered exocentric constructions in modern Chinese included three different structures: the coordinate phrases, the modifier-head phrases and the special subject-predicate phrases. The coordinate phrases included the reduplicative forms and non-reduplicative form while the special subject-predicate phrases meant the phrases which played the role of clause component but not the clause itself.

具体说来，现代汉语中的名核离心结构包括联合式、偏正式和特殊主谓式三种，联合式当中又可以分为重叠式和非重叠式；特殊主谓式主要是指充当句子成分，而不是作为小句的主谓结构。

When they built up the quantum Liouville equation inthe phase-space representaiton and discussed the mathematicaltransformation of the wave functions between the coordinate ormomentum and phase space,Torres-Vega and Frederick alwaysassumed the positive series expansion in coordinate of potentialsof systems.This is obviously incomplete because potentials ofreal systems contains in general negative powers of coordiante.
