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
The Funan-Huoqiu area is located in the border tectonic belt between the North China and South China active block regions. By means of seismological and geological surveys and synthetic analysis, evid
