电子脉冲

In Chapter 4, we study the unpulsed high energy emission from millisecond pulsars.

但高能电子在光速圆柱以内的辐射仍是脉冲的。

Electromagnetic pulse generated by electrostatic discharge spark can severely interfere in normal operation of the electronic systems and even damage them.

静电放电火花产生的电磁脉冲会对电子系统的正常工作造成严重的干扰，甚至造成系统的损伤。

The bovine shank bone tissue was ablated with pulsed CO2 laser in vitro, electronic drill was used as a control group. Then the morphology of bone tissue was examined by using stereomicroscope and scanning electron microscope. The crater depth was measured with optical coherence tomography.

选用脉冲CO2激光对离体牛胫骨组织进行消融，以电钻作为参照组，体视显微镜和扫描电子显微镜观察骨组织弹坑的形态学变化，光学相干层析成像技术测量弹坑消融深度。

It is presumed whether the electron temperature can rise up quickly in the early discharge and fall down rapidly during the discharge afterglow is the key to realize the alternate oscillation of self-terminating and recombination lasers in univalent ions of strontium in experiment.

分析了两种激光交替振荡的发射过程、脉冲宽度特性和粒子数反转机理，认为在放电早期和余辉期电子温度的急剧升高和降低是Sr离子自终止和复合激光实现交替振荡的关键所在。

It indicates that the theory of monoatomic layer can't explain perfectly emission mechanism of La2O3-Mo cathode;the excess active lanthanum is crucial element to the improvement of thermionic emission.

The morphologies of structural changes in the two inorganic silicon materials have been investigated by means of charge coupled device camera and scanning electron microscopy.

对这两种无机硅材料在飞秒脉冲作用后的微区结构改变进行了扫描电子显微镜测试，研究了其形貌特征。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
