Examples
- Test method for determination of isothermal secant and tangent bulk modulus
等温正割和正切体积弹性模量测定方法 - Standard test method for determination of isothermal secant and tangent bulk modulus
测定等温正割和正切体积弹性模量的标准试验方法 - It is proved that hyperbolic - secant pulses ( solitons ) have inherent ability to suppress pmd , this adaptive ability is due to the balance between nonlinear xpm effect and pmd effect . it is studied on the influence of polarization - mode dispersion on wdm system in this dissertation
大量研究已经证实了双曲正割形脉冲(孤子)对偏振模色散具有本征抑制能力，这种自适应能力归功于交叉相位调制效应与偏振模色散效应之间达到平衡。 - 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。
