瞬态

Transient and surge are the instant aberrance of the voltage and electric current on the simple alternating current wave circuit.

瞬变和浪涌是正弦交流波电路上电压与电流的一种瞬时态的畸变。

The life time of the metastable n -phase state is evaluated explicitly in term of the instanton method.

对于亚稳的π-位相态，我们利用瞬子技术计算了它的衰变率或寿命。

As required by the working features of monostable flip flops, the design idea of monostable flip flops with RC circuit as the timer unit is explained by using the transient phenomenon of signal changing resulted from the differential circuit or from "the static race hazard of signal", and by linking the storage principle of signal feedback.

根据单稳态触发器工作特点的要求，以RC电路为定时单元，利用微分电路及"信号静态竞争冒险"等信号瞬变现象，并结合信号反馈存贮的原理，阐明单稳态触发器的设计思想。

The concepts to be introduced include, but are not limited to, the random phase approximation, the mean field theory (aka saddle-point, or semiclassical approximation), the tunneling dynamics in imaginary time, instantons, Berry phase, coherent state path integral, renormalization group..

这些方法主要涉及如无规相近似、平均场理论(aka 鞍点或半经典理论)、虚时间中的隧道动力学、瞬子、贝里相、相干态路径积分及重整化群等概念。

First, we construct two typical molecule four quark states with quantum number $1^{-+}$.

我们首先构造了两个典型的$1^{-+}$分子四夸克态，利用考虑瞬子效应修正后的QCD求和规则研究它们的质量问题。

Some regularities of the wave propagation were found from this closed system.

从这个封闭系统中发现了一些瞬态波传播的规律和特点。

In the third chapter, Based on the Bloch equation and with the use of methoddevoloped in chapterl, the level shifts of two-level atom are calculated under theinteration of classical and quantized field. An analytic formula of level shift of atomin AC Zeeman effect is obtained.

从本章给出的计算方法中，还揭示了当一量子系统受到一与时间相关的微扰并发生跃迁时，微扰引起的能级移动是一个与跃迁同时发生的瞬态过程，跃迁和能级移动是同一过程的两个方面。

The Cherenkov telescopes do not actually detect the gamma rays directly but instead detect the flashes of visible light produced when gamma rays are absorbed by the Earth's atmosphere.

只有10 ％的伽玛射线源的非瞬态来源。这些稳定的伽玛射线发射器包括脉冲星，中子星和黑洞的候选人，如活动星系核。

Because of its convenience, the method of transient rayleigh waves has been extensively used.

瞬态法因其施工方便、快捷得到了广泛应用。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
