hyperbolic secant meaning in English
双曲正割
Examples
- On this basis , a model of pulse damage threshold fth ( j / cm2 ) was proposed . calculations on pulses of three different envelope shapes indicate that , with the same pulse duration , wavelength and incident light intensity , fth of pulse with gaussian envelope is higher that that of the pulses with hyperbolic secant and lorentzian envelope , i . e . gaussian pulse would need a little higher intensity to induce breakdown than the other two
在这个基础上，提出了一个研究脉冲破坏闭值的模型，对三种不同包络脉冲的分析表明，在相同的脉宽、波长和入射光强下，高斯脉冲的破坏闭值较高，双曲正割和洛仑兹脉冲的破坏闽值相对较低，即高斯脉冲最不容易对介质造成破坏。 - Shapes of pulse envelope are found to have some effect on the degree of phase influences . dependence of single - cycle pulse ( scp ) energy on the carrier phase has been studied for gaussian , lorentzian , hyperbolic secant and sine shapes respectively , which shows that these energies can be expressed in the same form . phase effect on pulse with gaussian envelope is the first to show , then are hyperbolic secant and lorentzian pulses , and sine the last
包络对载波相位的作用范围也是有一定影响的，我们对高斯、洛仑兹、双曲正割和sinc四种不同包络的脉冲，研究了单周期脉冲能量随载波相位的变化规律，发现以上四种脉冲的归一化能量均可在形式上用同一表达式表示，并发现对于这四种不同包络的脉冲，高斯脉冲相位的作用最早体现出来，然后是双曲正割和洛仑兹脉冲， sinc脉冲最迟。 - We have calculated and plotted the curves of the refractive index , group velocity index , lowest - order and second - order dispersion indexes as a function of wavelength . the lowest - order and higher - order dispersion - induced broadening and deforming of light pulses is analyzed for various pulse shapes , such as gaussian , super - gaussian and hyperbolic secant pulses
给出了折射率、群速指数、低阶和二阶色散系数随波长变化的关系曲线，研究了高斯脉冲、超高斯脉冲和双曲正割脉冲等超短脉冲在clbo晶体中传播时，由于低阶色散和高阶色散引起的脉冲展宽和形变。
