The bonding and antibonding character for the CO valencelevel have also been studied by analysis of the variations of the molecular eigenvalues when the CO molecule approaches the surface.
通过CO分子接近表面时各分子轨道能量本征值的变化，讨论了各轨道的成键、反键特征。

On the contrary, semantic valence combination is the semantic-syntactic phenomenon that two semantic valences of a predicate could be expressed by one syntactic valence at the syntactic level.
语义配价合并则相反，指的是谓词的两个语义配价在句法结构层面上用一个句法配价体现的语义-句法现象。

The syntactic positions which are connected by the predicate at the syntactic level are called the syntactic valence of the predicate.
