Application of wind power prediction tools for power system operations The wide use of wind energy in Germany results in a lot of new power system operation problems corresponding especially to the stochastic character of the ... K Rohrig,B Lange - Power Engineering Society General Meeting 被引量...
The samples are prepared by Ge ion implantation of mono-beam with two kinds of energy (or charge),different doses from 1×10 16 to 1×10 18 cm -2 and without subsequent annealing. 实验中利用不加磁分析器的离子注入机,采用Ge弧光放电离化自动形成的Ge+和Ge2+双电荷离子并存的单束双能离子注...
The decay possibilities of atoms with two K-shell vacancies have been studied by bombarding a thin (465 mug/cm2) Al target with electrons of E0=20 keV. In addition to the more common probability involving a sequential decay [which leads to a K-2-->K-1L-1 transition with the emission ...
