Synthetic seismograms of ground motion near earthquake fault using simulated Green’s function method

Seismograms near source fault were synthesized using the hybrid empirical Green＇s function method where the discretely simulated seismic waveforms are used for Green＇s functions instead of the observed waveforms of small earthquakes. The Green＇s function seismic waveforms for small earthquake were calculated by solving wave equation using the pseudo-spectral method with the staggered grid real FFT strategy under a detailed 2-D velocity structure in Kobe region. Magnitude and seismic moment of simulated Green＇s function waveforms were firstly determined by using the relationship between fault length and corner frequency of source spectrum. The simulated Green＇s function waveforms were employed to synthesize seismograms of strong ground motion near the earthquake fault. The synthetic seismograms of the target earthquake were performed based on the model with multiple source rupture processes. The results suggest that synthesized seismograms coincide well with observed seismic waveforms of the 1995 Hyogo-ken Nanbu earthquake. The simulated Green＇s function method is very useful for prediction of the strong ground motion in region without observed seismic waveforms. The present technique spreads application field of the empirical Green＇s function method.

土壤结构对土壤入渗能力的影响

基于不同土壤结构条件下的大田土壤积水入渗试验资料，分析讨论了土壤结构对大田土壤水分入渗能力和Kostiakov-Lewis三参数模型参数的影响。试验结果表明：土壤结构对大田土壤入渗能力的影响十分明显；土壤结构由疏松变密实，土壤入渗能力递减；3个入渗参数值随着土壤结构由疏松变密实而递减。研究结果对于地面灌溉合理灌水技术参数的确定及水资源合理利用具有重要价值。

论我国高师化学教法课程的学科定位、体系与实施

我国高师化学教法课程的学科定位一直存在严重偏差，致使学科内容体系支离破碎、机械移植的教育学和教学论条，其间既缺乏相应的化学个性，又鲜有学科独具的理论．鉴此，本文从课程设置宗旨出发，将化学教法课程定位于一般教学论与化学教学实践之间，由此构建了具有严密逻辑性的“三层(原理层、模式层和技能层)教法课程体系”，并提出“试讲指导课型”“绿色试题”等关键性实施要点。
