This makes the system of orbitals unstable and an electron from an orbital further out rapidly fills the hole.

这使得轨道系统不稳定，外一层轨道的电子会迅速跃迁到内层空轨道上，填补空穴。

The relationships between welding pool width, wire extension and welding parameters including welding current duty ratio, base current, peak current, welding speed and wire-feeding speed were studied. Through large numbers of welding experiments, aluminum alloy pulsed MIG welding dynamic process were identified by the curve fitting method, and the mathematical models between welding current duty ratio, base current, welding speed, wire-feeding speed and wire extension were obtained, succeeding the model between the above parameters and weld pool width.

介绍了铝合金MIG焊焊接电流占空比、基值电流、峰值电流、焊接速度、送丝速度对熔宽的影响规律，并在其基础上，通过平板堆焊试验研究了这些参数对焊接干伸长的影响规律；在铝合金机器人脉冲MIG焊平板堆焊过程各焊接参数与正面熔宽之间的传递函数的基础上，采用铝合金平板堆焊阶跃试验，利用曲线拟合法辨识了铝合金机器人脉冲MIG焊动态过程传递函数，建立了焊接电流占空比、基值电流、焊接速度、送丝速度与焊接干伸长之间的对象数学模型。

Under an appropriate condition, the squeezed vacuum field can trap the two atoms inri.An analytical expression of emission spectrum for three-level atom interacted with two-mode cavity field is given. The effects of the initial state of system on the emission spectrum for three-level atom are explored.

我们给出了好腔中与双模腔场相互作用的三能级原子发射谱的一般表达式，探讨了系统初态对三能级原子发射谱的影响，阐明了只有原子和双模驱动场初始时刻均处于相干叠加态，原子不同跃迁通道间的量子干涉才使得原子发射谱呈现相位敏感性。

Firstly, PLL linear model is established in order for the comparative analysis between phase step error response and phase rectangular-pulse error response under different damping ratio. The ideal PD waveform expression is figured out.

首先通过建立锁相环的线性化模型，对比分析了不同阻尼系数的相位阶跃误差响应和矩形相位误差响应，推导了理想状态下鉴相器输出的波形表达式。
