Even-level ladder system has been analyzed for population transfer by counterintuitive frequency-chirped laser pulse, in which intermediate states are strongly coupled by dressing laser field.

利用"反直觉"频率啁啾激光脉冲分析了偶能级ladder系统的布局数迁移，其中在缀饰激光场作用下N-2个中间态进行耦合。

The experimental results show that the distribution founction p of the whole signal group and the different pulse width subsets all fit the lognormal distribution with very high precision in the amplitude's field of definition (V0,VM) under the condition of the big samples, which indicates that the random signal group has the statistical fractal (self-similarity) characteristic.

实验数据表明，在大样本条件下，脉冲信号集合整体及不同脉宽信号子集的p 函数在幅度定义域(V0，VM)内均以很高的精度满足对数正态分布形式，即该随机脉冲信号群具有统计分形特征。

In the absence of pulse input, the power of incentives in the winding gap magnetic field under the rotor can maintain the original location in the targeted state.

在没有脉冲输入时，在绕组电源的激励下气隙磁场能使转子保持原有位置处于定位状态。

In the experiment,by adjusting the manual tunable fiber Bragg grating and control the transmission of the light through the filter band,the operating center wavelength of the fiber lasers could be tuned from 1 047 nm to 1 055 nm and pulse duration at a repetition rate of 4.9 MHz.

实验中，在保证锁模状态稳定的情况下，通过调节可调谐光纤光栅滤波器，使激光器输出锁模脉冲的中心波长在1 047 nm～1 055 nm范围内连续调谐，重复频率稳定维持在4.9 MHz。

How to reduce the energy consume so that the quality of the interceptor would be reduced and enhanced the final velocity and average velocity are the key technology of the system scheme for LRADI. Aimed at the character of the LRADI, analysis and study the questions of adoption"interval time can be changed double pulse Solid Rocket Motor"and"double high cast virtual target composition guidance trajectory".

因此如何降低能量的消耗、减轻拦截器的重量，提高末速度和平均速度成为远程反空气动力目标拦截器总体方案的一个重要关键技术，本文针对远程反空气动力目标拦截器的特点，提出和论证了采用"间隔时间可调的双脉冲固体火箭发动机"和"双高抛虚拟目标复合导引飞行弹道"两条新技术途径相关的各种问题。

Firestone (1940) and Simons (1945) developed pulsed ultrasonic testing using a pulse-echo technique.

在医学中，可以利用超声波进行人体内部器官的组织结构扫描和血流速度的测量等。

In DP-CELP, the excitation was generated by means of convoluting the algebraic code vector with a fixed dispersion pulse. The constructed speech quality was efficiently improved with this excitation, but the search complexity for algebraic codebook was not increased.

该算法为低速率编码算法，激励矢量由特殊结构的代数码书与固定形式的散布脉冲的卷积获得，这种激励源既有效地改善了重建语音质量，又未增加代数码书搜索的复杂度。

I believe they were originally used to pulse a flash lamp in an airport.

我相信它们最初是用来为机场的闪光灯供电的。

The experimental results show that the increase of the centroid transverse displacement in the beam-pulse flattop duration is confined and the bigger energy-sweep beams are partially rejected in the alternate focusing solenoid field.

实验结果表明，采用交变极性聚焦场聚焦，抑制了束脉冲顶部质心横向运动的发展，同时可剔除束脉冲前后沿能散度较大的那部分束。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
