It is also shown that under the same conditions, the values of the LWI gain with incoherent pumping are evidently larger than those without incoherent pumping exceptΦ=0 and the time reaching the steady state is shorter; varying the initial condition doesn't change the stationary value of the LWI gain but can remarkably affect the transient evolution process of the LWI gain.

研究还表明，与不存在非相干泵浦时相比，除了相对位相Φ=0的情况外当存在非相干泵浦时系统可得到大得多的稳态增益，而达到稳态所需的演化时间也短得多；初始条件的变化不改变稳态增益的大小但对瞬态演化过程有明显的影响。

Some methods to improve the system's output SNR by coherent or noncoherent operating are also discussed.

最后讨论了用相干或非相干处理来改善系统输出信噪比的方法。

To reduce the receiver complexity,a differential space-frequency transmit diversity scheme was developed with a noncoherent detection method based on the frame structure of the time domain synchronous-orthogonal frequency division multiplexing system.

在采用相干检测方法的发射分集方案中，进行信道估计需要付出很高的代价，为了降低接收端的实现复杂度，根据时域同步正交频分复用系统结构的特点，提出了差分空频发射分集及相应的非相干检测方法。

This method is used for decomposing the velocity data measured by ADV in the wake flows of trashrack with large length-to-width ratio.

该算法以湍流相干分量和非相干分量的相关系数作为迭代的控制指标，减小了过去算法中的随意性。

The transition radiation faculae on the rear side of a 20m thick target Ta was a smooth round structure with the center brighter than the periphery, indicating incoherent transition radiation and coherent transition radiation, which is close to the results of the theoretical simulations. For a 100m thick target Ta, the faculae was a star-structure and became smaller, which resembles a star-structure of the energetic proton emission. For a 10μm Ta+10m Cu+5m Ta composite target, the faculae was a ring structure and became bigger and non-uniform, looked like two apart faculae.

在厚度为20μm的Ta靶背表面观测到渡越辐射光斑呈现较平滑的圆形结构，而且中心亮度高于周围，这包含了非相干与相干渡越辐射的成分，与理论模拟结果接近；在厚度为100μm的Ta靶背表面观测到渡越辐射光斑呈现出星状结构，光斑较小，与高能质子发射出现的星状结构极其相似；在复合靶背表面观测到渡越辐射光斑虽然也呈现大致的圆形结构，但光斑较大，而且极不均匀，中间有很明显的光斑分裂。

The new algorithm can resolve the problem of localising the correlated and uncorrelated signal sources at one time under the correlated noise field.
