A method estimating the stress level in the focal region of an earthquake is proposed here. Taking the 2001 M=8.1 Western Kunlun Mountain Pass earthquake as an example, we estimate its stress level in
On the basis of the velocity field results of horizontal crustal movement obtained from GPS measurements during the periods of 1993~1999, 1999~2001 and 2001~2003 in the northeastern margin of Qinghai-
We discuss the influence of precipitation and groundwater on the deformation behavior of the Babaoshan fault of Beijing by using long-term observation data from Dahuichang station during 1970~2003. Th
Based on 266 strong ground motion records, an attenuation relationship was developed for both absolute and rela-tive input energy spectra. The comparison of the two kinds of input energy spectra const
The recently developed quasi-analytical algo-rithm (QAA) is a promising algorithm for deriving inherentoptical properties from ocean color. Unlike the conventionalsemi-analytical algorithm, QAA does n
The subcellular distribution of arsenic (As) in Pteris vittata L., an As-hyperaccumulator, was studied to de- termine As compartmentalization and to explore the mecha- nisms that confer As tolerance.
用于生物识别的生物特征有手形、指纹、脸形、虹膜、视网膜、脉搏、耳廓等, 行为特征有签字、声音、按键力度等。基于这些特征,人们已经发展了手形识别、指纹识别、面部识别、发音识别、虹膜识别、签名识别等多种生物识别技术。指纹识别技术:现在的指纹识别系统采用了电容传感器技术,由电容传感器发出电子信号,这个电子信号将穿过手指的表面和死性皮肤层,最终达到手指皮肤的活体层(真皮层),直接读取指纹图案,从而大大提高
In this paper, the spatial-temporal gravity variation patterns of the northeastern margin of Qinghai-Xizang (Tibet) Plateau in 1992～2001 are modeled using bicubic spline interpolation functions and th
