Photosynthetically active radiation(PAR) is essential for plant photosynthesis and carbon cycle,and is also important for meteorological and environmental monitoring.To advance Chinas disaster and env
We process ambient noise data from seismic stations deployed in central Asia to determine the crustal shear wave velocity structure beneath the Tianshan Mountians and surrounding area.About 748 inter-
As revealed by field investigations,the co-seismic surface rupture zone of the 2010 MS7.1 Yushu earthquake,Qinghai is a characteristic sinistral strike-slip feature consisting of three distinct sinist
春。五月。又见英雄的五月。如果说两年前5.12汶川地震的关键词是"猪坚强",那么今年,是花坚强,是花在"亮剑"。请把眼界打开,放眼望去——冬寒去尽,京城那些花期被逶迤推迟的繁花争相吐艳,三月的桃花、梨花、丁香花、迎春花与五月的海棠花争艳落成花海,四月的杨花把这个五月装扮成"雪"的世界……这个五月整合了整整一个春天的资源。把美丽尽情地回报人间。而青海玉树地震也是如此,据本期封面人物赵健英介绍,玉树地
Na+ ions play an important role in the growth of halophyte. The effect of Na+ ions on nitrate uptake and osmotic adjustment in the euhalophyte Suaeda physophora was investigated under glasshouse condi
Fourier spectra and acceleration response spectra of near-field acceleration records of the 2008 Wenchuan Earthquake have been calculated.Relative fundamental frequencies(or predominant periods) were
Passive image interferometry (PII) is becoming a powerful tool for detecting the temporal variations in the Earths structure,which applies coda wave interferometry to the waveforms from the cross-corr
Long-time cross correlation of ambient noise has been proved as a powerful tool to extract Greens function between two receivers.The study of composition of ambient noise is important for a better und
We present a new approach to polarization analysis of seismic noise recorded by three-component seismometers.It is based on statistical analysis of frequency-dependent particle motion properties deter
We determine the three-dimensional shear wave velocity structure of the crust and upper mantle in China using Greens functions obtained from seismic ambient noise cross-correlation.The data we use are
