Experiments on sonic transmission show that a slabstone can directly transmit part of the energy of a wave excited by knocking or by a transducer into the air. The other part of the wave energy can generate the normal mode of vibration on the slabston

关于植物进行光合作用的机理研究,几百年来 一直是科学研究的一个重大课题。最近,我国科学 家率先独立完成了这一课题的核心问题研究。国际 权威科技期刊《自然》以封面和评论文章的形式发表 了我国科学家的研究成果。 中国科学家破解菠菜主要捕光复合物Ⅱ 的晶体结构
The multi-modes feature, the measure of the manipulating flexibility, and self-reconfiguration control method of the underactuated redundant manipulators are investigated based on the optimizing techn
在图像目标识别中,目标图像平移、尺度和旋转不变性是一个重要前提,而高阶矩特征存在稳定性差的缺点.提出采用主分量分析(PCA)方法确定目标在最大方差意义下主轴的旋转角度,并结合稳定性好的低阶矩特征实现目标的平移、尺度和旋转不变性变换;然后利用独立分量分析(ICA)良好的目标特征抽取能力,在各目标特征空间重建目标模型,并通过对重建模型的误差分析实现目标识别;最后通过PCA确定目标旋转角度测试和ICA目

Comparative analysis between the quantitative data of active faults and seismicity reveals that a complete earthquake recurrence cycle includes the characteristic earthquake and the sub-maxima earthqu
Using GPS observations of horizontal movement from 2001 to 2003 and the cross-fault mobile short-levelling data of 1988～2003, and with the aid of the improved negative dislocation model and the time-v
In order to determine the degree of returning_to_zero of temperatures of deformed calcite, a series of rock-breaking experiments were designed to test calcite-rich limestone samples under fixed confin
The results inferred from experiments with analogue models carried out previously have shown that two types of plastic-flow waves, “fast-waves" and “slow-waves", are induced in the lower lithosphere (
