解釋

We have calculated one - and two - photon absorption cross sections of the lowest excited states of a series of molecules combined with benzene, stilben, thiophene as center attached with amine, diphenylamine, diethylamine as electron - donor and nitryl as electron - acceptor ; the effects of molecular length, n center and electron - donor on two - photon absorption cross sections have been studied and all calculations have been carried out using the density functional theory at an ab initio level. it is found that the molecular length and the one - photon absorption intensity are quite strongly c orrelated factors, and that a corresponding correlation for the two - photon absorption is decreasing. it is also found that a most crucial role for the two - photon absorption is played by the n center

Rapd ( random amplified polymorphic dna ), which bases on the polymerase chain reaction ( pcr ), is by far one of the most commonly molecular techniques to uncover dna sequence polymorphisms. the basic priciple of this technique is that an arbitrary primer ( usually lobp oligonudetide ) is used to amplify random segments of dna, and a small number of fragments will be amplified when the primer anneals on each strand over a length range. if sequence variation is present at the priming site, then a fragment may not be amplied, so the dna polymorphic can be detected
