The fundamental properties of laser-induced plasma in liquid water, such as the ultrafast electron migration and solvation, have not yet been clarified. We use 1650-nm femtosecond laser pulses to induce the plasma in a stable free-flowing water film under the strong field ionization mechanism. Moreover, we adopt intense terahertz (THz) pulses to probe the ultrafast temporal evolution of quasifree electrons of the laser-induced plasma in water on the subpicosecond scale. For the first time, the T

By the 90 deg. elastic light scattering investigation and far field observation in the range of 20-800 centigrade, the relation between behavior of light scattering anomalies and evolution of nanodomain structures in lattice of barium sodium niobate (Ba2NaNb5O15, BSN) crystal was clarified. The correlation between anomalies on the temperature curves of the elastic light scattering intensity and temperature transformations of nanodomains was studied by X-ray and electron microscope methods. Phase

提出了一种用于全局优化的混合差分进化算法。 在新算法中,混沌系统的随机性被用来在搜索空间中尽可能多地散布个体,模式搜索方法被用来加速局部开发,而DE算子被用来跳到一个更好的点。 证明了全局收敛。 详细研究了三种典型的混沌系统。 在包含13个高维函数的基准示例上的数值实验表明,该新方法以较少的计算量实现了更高的成功率和最终解决方案。
