摘　　要：根据作者之一提出的共价的新定义，用DV－XαSCC和自然健轨道法研究了［MeBe（C≡CMe）NMe3］2，［Be（C≡CR）2］n，［MeBeH·NMe3］及（BeH2）n等化合物中铍原子的共价．结果表明，在这几种化合物中铍原子的共价都是6．In this paper, the electrouic structures of [MeBe(C≡CMe)NMe3]2 and [MeBeH·NMe3]2 were studied with the methods of DV-Xα SCC and natural bond or bitals(NBO), and then the covalences of Be in [MeBe(C≡CMe)NMe3]2, [Be(C≡CR)2]n,[MeBeH·NMe3]2 and (BeH2)n were discussed on the basis of the new definition of cova lence proposed by one of the authors .The results show that the covalences of Be in all these compounds are 6.
