Computationalresults indicate that the no-planar trans-benzanilide is the most stable structure. The spectra indicate that the Franck Condon region photodissociation dynamics have multidimensional character withnine activemodes. The intensity of υ24 mode in methanol is much stronger than that in acetonitrile. Compared with fatty amides and benzamide, phenyl substitution for H atom on-NH2 group makes C=O solvent effects disappear.
结果表明,苯甲酰苯胺的非平面反式结构为最稳定结构;在Frank-Condon区域内,苯甲酰苯胺主要由9个活性振动模组成;其中ν24(苯环上C=C不对称伸缩振动和CCH的面内弯曲振动,NH面内弯曲振动)振动模在甲醇溶剂中的强度远远大于其在乙腈的强度;与脂肪酰胺类化合物和苯甲酰胺的研究结果比较发现,苯基取代-NH2上的H原子使得C=O不再具有明显的溶剂效应。

Hexachlorocyclophosphazene was prepared using phosphorous pentachloride and ammonium chloride as raw material, hccp was mixed with Montmorillonite which aimed to decrease MMT.'s hydrophilicity. Solid state reserve cell of Mg│reformed MMT.│polymer gel containing water│graphite was assembled, and cell performance was tested. XRD and IR results show: When mass percentage lower than 9.1%, hccp mixed with MMT to form homophase, hccp phase was observed in the mixture when percentage higher than 9.1%, for hccp specific diffraction peak appears in XRD data, and 1220cm-1 which was assigned to P=N double bond 's expand vibration appears in IR data.

This intormation is combined in the structure of a Bayesian Graph so as to identify unknown or unpredictable faults. The final experiment results show the intelligent agent can detect network abnormal behavior before a fault actually occurs. Event correlation algorithm for network fault real-time isolation and handle uses object-oriented model method for critical network device and a novel coding scheme, even if in the case of lost alarm and wrong one, it also can identify the fault origin and automatically adapts to changes to network topology to ensure seemless scalability to large and complex network environment. Its performance greatly presides over traditional rule-based event management system.

The force is dominated by entropy force when the chain isdeformed less than 0.9 of the full-extended chain, while by enthalpy force. Theenthalpy force is contributed by the intro-molecular interaction. Bond stretchcontributes to the force more than bond angle bend. Torsion and VDW contributelittle to the force.3. The internal energy contribution to the elastic force It is in dispute that whether 〓 is dependent on the strain, and it is hard toresolve the problem using present elastic theories because they are athermal.
我们模拟了聚乙烯模型聚合物的SMFS,研究了链长、势能有效距离和温度对力谱的影响,探讨了力谱的本质问题,得到以下结果:改进的分子动力学方法可以很好的模拟聚合物的SMFS;SMFS是链段的性质而不是整个高分子链的性质,对于聚乙烯,该链段碳原子数目大于40;SMFS的本质是熵弹性,形变小于全伸直链的0.9时,力为熵弹力;形变超过全伸直链的0.9时,能弹力占主导地位,这种能弹力完全是分子内相互作用引起的,是由键伸缩和键角弯曲贡献的。3。
