In this paper,a systematic direct perturbation method of dark solitons is found.Having analyzed the mistakes in earlier works on perturbation method for dark solitonsand essence of the direct perturbation method for bright solitons,we notice that to in-troduce the adjoint solutions of the squared Jost solutions and to prove the completenessare crucial to the problem.Giving up the unnecessary scheme of introducing the adjointoperator in the bright soliton case,we directly find the adjoint solutions by meetingthe demand for the orthogonality that inner product of the squared Jost solutions andits adjoint should be proportional to a δ function in the case of continuous spectra.The corresponding adjoint operator is thus found.Taking into account the reductiontransformation,we find a correct description for the completeness of the squared Jostsolutions and directly verify its validity with explicit expressions of the squared Jostsolutions.

The photoconductive properties of the pigments containing anthraquinone are studied in bilayer photoreceptor. A linear relationship between pigments that bear a substituent in the anilide ring in the coupler moiety and Hammett constant σ was obtained. Therefor, we conclude that electron-withdrawing groups enhances the sensitivity of these pigments.

Male patient was prevalent in aphasic groups, but mean age of both gender groups was no difference. The possible explanations may be adduced for our findings; one is related to the cerebrovascular changes of aging- The decrease of cerebral circulation is prominant and disseminated in increasing age. There may be changes in the cerebral blood flow associated with aging, predisposing different brain areas to stroke. The second is possible that changes in cognition, deterioration of memroy and comprehension disturbance may predispose the perception dysfunction of language or advanced language dysfunction like global aphasia in aging group.
