In this paper analyzing stationary structures of NH~+_(4)(H_(2)O)_(n)(n=1~6) clusters,it is found that the first stationary structure is linear hydrogen bonding NH~+_(4) with H_(2)O in clusters,the second is bifurcated structure,the third is trifurcated structure.
本论文分析了NH4+(H2O)n(n=1~6)簇合物的稳定结构,发现NH4+与H2O以线性氢键结合成的簇合物结构最稳定,其次是二叉结构,再次是三叉结构。
Methods Nonequilibrium statistical theory of fracture was made and the blocking influence of triple junctions on crack growth was considered .
方法用非平衡断裂统计理论框架并且考虑了晶体内部三叉结对裂纹阻塞的影响。
