时滞

The spectral lag distribution of the short GRBs is significantly different from that of the long GRBs.

排除统计涨落效应，仍有17％的短暴具有负的光谱时滞，即高能光子滞后于低能光子。

Then, some criteria, i.e., the sufficient conditions, for the asymptotical stability of the system in form of mean square are given by linear matrix inequality, which can easily be checked by Matlab toolbox.

然后基于线性矩阵不等式技术，给出了时滞随机分布参数系统稳定的充分条件，所得到的结果表示成线性矩阵不等式的形式，所以易于验证。

Based on the Lyapunov stability theory, a delay-dependent criterion is proposed to guarantee stabilization of the closed-loop system.

应用Lyapunov稳定性理论，得到了时滞相关的判据以保证闭环系统的鲁棒镇定性。

Secondly, based on some results of the robust stability of discrete singular systems with time-delays, a switching function with difference compensator is designed, which guarantees that movement of the system is asymptotically stable in a quasi-switching manifold.

其次，在上述分解的基础上，根据离散时滞广义系统鲁棒稳定性的有关结果，设计了带有差分补偿器的切换函数，使得系统在准切换流形上的运动渐近稳定。

According to this algorithm, it is shown that the bifurcated periodic solutions through Hopf bifurcations at the first critical value of delay are orbitally asymptotically stable on the center manifold and the bifurcated periodic solutions through Hopf bifurcations at other critical values of delay are unstable.

根据这一算法，发现在时滞的第一个临界值处通过Hopf分支产生的周期解在中心流形上是轨道渐近稳定的，而在其它临界值处通过Hopf分支产生的周期解在中心流形上是不稳定的。

Ordinary shares stand a good chance of doing better on this score, because profits can be expected in the end to rise roughly in line with the general price level, though there may be prolonged periods when this does not hold good.

普通股这时便有了出色表现的机会，因为可以预见，利润最终会根据价格总水平上涨的程度大体同步地上升；然而可能这不会马上见效，因为存在时滞。

Therefore, investigating the stability and the control of delay stochastic systems is very important in theoretical and engineering sense.

因此，研究时滞随机系统的稳定和控制问题具有重要的理论意义和实用价值。
