We present an algorithm for the inverse scattering problem associated to the Dullin–Gottwald–Holm equation, arising in the study of the unidirectional propagation of waves in shallow water. In addition, a sufficient condition which guarantees the existence of the low regularity solutions for the generalized Dullin–Gottwald–Holm equation is studied by the method of energy estimation. 相似文献

We should be careful about the effect of oxygen deficiency on polymeric track detectors even at balloon altitude. Results of balloon experiments and calibration experiments in a vacuum chamber at different pressures show that the effect of oxygen deficiency becomes serious at a pressure below 10 hPa. 相似文献

Phosphonamidate peptides were prepared in good yields by reaction of ethoxy(phenyl)phosphinate with free peptides in a mixed solution of H2O, C2H5OH, Et3N and CCl4 at room temp.; their in situ electrospray ionization mass spectra exhibited high sensitivity compared with the free peptides, and sequential loss of amino acid residues of the sodiated phosphonamidate peptides from the C-terminus was found in multistage ESI mass spectrometry. The results show that N-phosphonyl derivatization combined with multistage ESI-MS is a powerful method for peptide sequencing. 相似文献

Alleviation of thermally induced phase mismatch in CsLiB6O10 crystal by means of temperature-profile compensation 总被引:1,自引:0,他引:1
A new mechanism was found to alleviate the thermally induced phase mismatch of nonlinear optical crystals. By cooling CsLiB>(6)O(10) at an elevated crystal temperature with gas, we improved laser conversion efficiency from green (532 nm) to UV (266 nm) 2.3 times compared with that without cooling. In situ observation of the temperature profile on the output surface revealed that such cooling initiates a negative temperature profile that compensates for the positive profile generated from laser absorption. A 10.6-W UV output with excellent stability was generated. The optimum crystal length was substantially extended. 相似文献

Let 0≤g be a dyadic Hölder continuous function with period 1 and g(0)=1, and let $G(x) = \prod\nolimits_{n = 0}^\infty {g(x/{\text{2}}^n )} $ . In this article we investigate the asymptotic behavior of $\smallint _0^{\rm T} \left| {G(x)} \right|^q dx$ and $\frac{1}{n}\sum\nolimits_{k = 0}^n {\log g(2^k x)} $ using the dynamical system techniques: the pressure function and the variational principle. An algorithm to calculate the pressure is presented. The results are applied to study the regulatiry of wavelets and Bernoulli convolutions. 相似文献
