frequency jump
2.With the development of the microelectronics technology and computer science, because of quickly raised systematic clock frequency and continuously shorten signal jump edge,signal integrity(SI) problem become more and more prominent, more complicated and multi-condition analysis has been required during the design, expenses and time of simulating is increasing sharply.
3.Through comparison of various alternatives, the optimal alternative in terms of layout of flood releasing structures is recommended, which has 7 surface sluices in the central portion of the dam, 2 ski jump spillways on both banks and 2 bottom outlets near both banks. When flood frequency ?P≤5%? ,the 2 bottom outlets will be used in combination with the surface sluices and ski jump spillways to release flood.
