<正>Recent advances in landslide/avalanche modeling have been enabling us to investigate the kinematics of such catastrophic events with much more details.Taiwan is located in a region where seismic activities and extreme weather conditions frequently occur.One of their common consequences is the slope failure.In the past decodes,we witnessed at least three giant landslides:Tsaoling,Jiufenershan landslides,triggered by the Chi-Chi earthquake in 相似文献

The wide existence of immature oils throughout the world especially in China broke through the hydrocarbon generation theory through kerogen thermal degradation. Studies have shown that soluble and insoluble organic matter are organically connected in the sedimentary rock, both contributing to hydrocarbon generation. In the diagenesis,kerogen can not produce oils, so immature oils derive directly from the soluble lipids. Hydrocarbon generation process through kerogen thermal degradation takes place mainly in the early catagenesis(R o= 0.2% ～1.2%), and the oils generated are normal. In the late catagenesis, hydrocarbon generation comes into wet gas stage(R o=1.2%～2.0%), with pyrrobitumen degenerating into high mature light oils and oils cracking into gases. In this paper,the author presented a new generating hydrocarbon and evolutionary model with soluble and insoluble organic matter both contributing to the generation of hydrocarbon. 相似文献
