It has been found that the color center induced by irradiation results in a decrease of fluorescence outputs while the density of color center is affected by the neu.
利用常规的核探测技术,通过测量其辐照前后 Cs的γ能谱来观察峰总比的变化,研究了辐照诱导色心对于荧光输出和中子剂量对于辐照诱导色本底能谱和137心密度的影响。
Therefore the pulsed beam behaves like diffraction-free without any transverse spreading, while the temporal part changes as in the dispersive medium, which is dominated by the so-called spatially induced group velocity dispersion (SIGVD).
给出了含时的波动方程的一族特解——超短脉冲 Bessel光束 ,其脉冲光束的空间和时间部分可以做分离变量 ,空间部分在传输过程中保持 Bessel光束不变 ,而时间脉冲部分的传输行为类似于在普通色散介质中的传输 ,此效应被称之为空间诱导色散效
The spatially induced group velocity dispersion (SIGVD) can be used to compensate the dispersion of medium.
研究了超短脉冲贝塞尔光束在色散介质中的传输特性 ,指出空间诱导色散效应可以用来补偿介质色散作用 ,从而可以在色散介质中实现无衍射无色散的类时空孤子波的传输。
The laser induced dispersive fluorescence(LIDF) spectra technique has been used to stud.
在采用激光诱导色散荧光光谱对SO_2分子基电子态振动能级结构进行实验研究的工作中,SO_2分子吸收波长为266nm的激光,从基电子态X~1A_1跃迁到A~1A_2、B~1B_1耦合激发电子态的高振动能级,在270—470nm波长范围内,其色散荧光谱呈现出在弥散谱上叠加有规则振动序列结构的特征。
