In the case of center frequency f0 = 2780MHz, bandwidth △f= 200MHz, delay time t1≥8μs, t2≥16μs, and voltage standing wave ratio VSWR≤2.0, the capability of the pulse power of 20W can be realized in a matching state.
Objectives: 1. Using Multi-Detector-Row spiral CT angiography (MDCTA) (16-slice spiral CT) to investigate the visualization of the artery of Adamkiewicz with the optimized scanning parameters, scan delay time and reconstruction methods.
目的：①采用多排螺旋CT血管成像技术（multi-detector-row CT angiography, MDCTA）显示脊髓的根髓动脉（the artery of Adamkiewicz，简称Adamkiewicz动脉），探讨最佳的扫描参数、强化延时时间及图像重建方法；
Numerical simulation shows that a hyperchaotic dual-ring Er-doped fiber laser can be successfully controlled into different periodic states by this method only when the delay time and feedback intensity are suitably matching.
Selection of Embedding Dimension and Delay Time in Phase Space Reconstruction
A new algorithm is proposed for computing the embedding dimension and delay time in phase space reconstruction.
Thereafter, by means of the iterative algorithm of multiple autocorrelation and Γ test, the near-optimum parameters of embedding dimension and delay time are estimated.
Finally, the expression of the group velocity of the guided mode in optical planar waveguide was obtained, which clearly shows that the time delay upon total reflection is the sum of the group-delay time and the Goos-H?nchen time at given any time.
Ignition delay time was found to be longer than deflagration-to-detonation transition (DDT) time, and the sum of the two would change little as cycle frequency increased.
