Hyperspectral remote sensing data has the characteristic of combining both image data and spectral data into one data set, each pixel of a hyperspectral image an entire spectrum (consisting of numerous contiguous, narrow spectral bands) is present. Compared with conventional multi-spectral remote sensing data, hyperspectral remote sensing data can be more useful for the identification and classification of surface Materials. In this paper, the author classified the coastal area using hyperspectral remote sensing data, and further more, succeeded in extraction of sand beach surface information related to bearing capacity characteristic.

And the effect of the equivalent surface charge density on the surface depletion area for positively beveled p-n junction was also analysised.

分析了等效表面电荷密度对正斜角造型p-n结表面耗尽区的影响。

The key of the algorithm is how to estimate the derived vector of the surface curve or the first derivative of the surface of revolution according to the given length or area constraint.

算法的关键在于如何利用已知的弧长或面积约束来估计空间曲线或旋转面的旋转曲线在节点处的导向量或一阶导数值。

To better fit the lower amplitude P waveform, we employed two different weights for the P wave and surface wave arrivals, respectively. A grid search method was employed to find the strike, dip and slip of the earthquake that best fit the three-component records of P and surface waveforms recorded (the tangential component of the P-wave arrivals was not used). Synthetic waveforms were computed with an F-K method. Two crustal velocity models were used in the synthetic calculation to reflect a rapid east-west transition in crustal structure observed by seismic and geological studies in the study area.
