提出一种用于低信噪比光腔衰荡时间准确提取的信号平滑方法,该方法基于数字图像处理领域的空间滤波平滑技术。首先推导了这种平滑方法的平滑过程和平滑效率,并与其他平滑算法进行了对比。推导结果表明基于均值滤波算子的空间滤波平滑方法具有最高的平滑效率。其次,分析了信号平滑方法的实用效果,结果发现该平滑方法与加权线性最小二乘算法相结合能够实现高精度、快速同时准确度较好的光腔衰荡时间提取。最后结合实验数据检验了平
The halophyte Salicornia europaea L. is a widely distributed salt-tolerant plant species that produces numerous dimorphic seeds. We studied germination and recovery in dimorphic seeds of Central Asian
Stipa purpurea is widely distributed along a large precipitation gradient on the Tibetan Plateau.This implies that S.purpurea from different populations may have different responses to drought stress.
As the most influential strike-slip fault in East China,the Tancheng-Lujiang fault zone draws scholars attention for its strong seismic activity. Nevertheless,most research has been conducted along se
Since 231 B. C.,a total of 15 M6.0 - 7.5 earthquakes have been recorded in the west Beijing basin-range tectonic region( 38.3°- 41.5° E,112°- 116.2° N),a region mainly under the action of tensional no
In this paper,the main purpose is to analyze and research the characteristics of the geoelectric field observed data with a long time span and large amplitude abnormal change,at the Lhasa geomagnetic
In this paper,the Gaoyou-Baoying M_S4.9 earthquake was analyzed by the geomagnetic harmonic wave amplitude ratios method. The earthquake was an isolated seismic event,before and after which there were
