Since most of the large molecules containing phosphorus element have double bonds, it is necessary to consider the special structures of double bonds in order to deal with these large systems more accurately. So, based on density functional theory and electronegativity equalization principle, applying a general atom-bond electronegativity equalization method , using separated program, through regression and least-squares optimization , the parameters of atoms and bonds in molecules are determined . By these parameters , the charge distributions and the energy of some molecules containing phosphorus element, especial the fragment of DNA, RNA, are calculated . The results are quite good.

The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.
试验结果表明,长期在高温条件下服役,铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体,长期高温单边渗碳形成大量富铬碳化物,促使镍富集并起泡形成瘤状物,催化含碳气体的分解;表层瘤状物使辐射管表层疏松,表面积扩张,加快了碳向基体的渗入,提供了碳化物持续长大的条件,并引起沿碳化物周边开裂和奥氏体基体严重萎缩;合金元素的重新分布造成主合金元素铬和镍产生两极分化,镍和硅的富集促使石墨化,与侵入的氧形成内部氧化空洞和膨胀疏松,最终导致构件穿孔失效。
