在镍基合金可见光谱计算机模拟基础上，研究利用镍元素及成分元素特征谱线进行基体鉴别和成分元素分析的方法。 - Based on the results from the study , a method for matrix differentition and qualitative and semi - quantitative component analysis for cu - based alloy was developed with bright application prospect
利用铜元素及成分元素特征谱线进行了基体鉴别和成分元素分析，研究结果可用于合金基体鉴别及铜合金成分元素的定性和半定量分析。 - Similarly , in the spectrum of a star moving towards us , the characteristics lines would show a “ blue shift ” , i . e . , they would be displaced towards the blue end of the spectrum , corresponding to shorter wavelengths and higher frequencies
同样，在向我们靠近的恒星的光谱上，特征谱线会显示“蓝移” ，即谱线移向蓝端，就是说波长短而频率高。 - Observation of the on - off sequencing of characteristic spectral lines from tracer materials arranged in layers in , or surface patterns on , planar or spherical targets can provide a record of radial or lateral energy transport processes in laser - generated plasmas
测量激光聚变靶产生的软x射线时间变化连续谱的形状，可以知道许多x射线产生过程的详细动态记录，这有助于理解实验的热学条件。观察轨迹特征谱线的闭合序列，能提供关于激光等离子体激发能量和滞后能量的传输过程记录。 - The spectral correlation density must be estimated before the ds signal parameter estimation . in order to reduce the effect of random noise , we provide a improved method to estimate the spectral correlation density which is based on the average algorithm . it can make the spectral line be more obvious , and improved the snr limit when estimating these parameters
在利用ds信号谱相关域所表现的特征进行参数估计时,首先要利用有限时间数据对ds信号进行谱相关密度估计,为降低随机噪声对谱相关密度估计的影响,本文引入了集平均的思想,提出采用集平均的方法估计谱相关密度,从而在参数估计时,特征谱线更显著,提高了参数估计的信噪比容限。
