An ERP study for the degrees of the difficulty in visual search

The present study mainly probed the relationships between ERP components and the degrees of difficulty in visual search. Three experimental and one controlled conditions were randomly selected. Results showed that the P1, N1, and P2 amplitudes and latencies had no significant differences among the three experimental and one controlled conditions, and the ERP waveforms of low perceptual load of visual search were different from that of high perceptual load. These results might indicate that the latencies and amplitudes of initial P1, N1 and P2 in high and low perceptual load conditions were almost the same. The ERP waveforms of parallel search were very different from that of serial search, and the ERP waveforms of serial search were very similar. The P3 amplitudes increased as the degrees of the difficulty in visual search decreased.     

多维测量结果不确定度评价方法初探

为解决以多维矢量形式存在被测对象的测量质量评定问题,该文应用测量不确定度理论和多元概率统计方法,将测量不确定度理论进行了向多维的拓展;对多维情况下的测量不确定度传播律进行了推导;论述了多维不确定度的表示方法及空间几何意义;提出了以多维不确定度比较不同测量结果质量的方法;并给出了常用多维测量方法,如等精度独立多维测量和不等精度独立多维测量的不确定度评定方法。理论分析及仿真算例表明,所提出的理论具有较完备的体系,能够满足测量实际中常用多维测量方法的不确定度评定需求。     

The Response of Debris-Flow Events to Solar Proton Flares （Ⅰ）

By analyzing the observation data from Dongchuan Debris Flow Observation and Research Station and historical data from year 1965 to 1990 gotten from National Astronomical Ob-servatories/Yunnan Observatory,the responding of debris flow in Jiangjia Ravine to Solar Proton Flare is studied. The following conclusion can be drawn. Solar Proton Flare,as one of most im-portant astronomical factors,affects the activity of debris flow in Yunnan. Generally,from 1965 to1990,the more active Solar Pro-ton Flare is,the greater the probability of high frequency and large runoff of debris flow is. On the contrary,the less active Solar Pro-ton Flare is,the greater the probability of low frequency,small runoff,and low sediment transport of debris flow is.
