Because of no limitation to task granularity, ppa is especially suitable for scheduling fine granularity tasks ( also suitable for coarse and medium tasks of course ), consequently helpful theoretically and practically for studying task schedule algorithm for rtdcs. according to the principle of fault - tolerant scheduling, combined with characteristics of tft in rtdcs, the paper puts forward the scheduling model of tft, corresponding implementation mechanism and the dynamic fault - tolerant scheduling algorithm ( namely ftpb ) and analyzes its complexity, with experimental data and contrast table compared with other analogic algorithm

動物還具有比環節
動物更高級的特徵,如:身體分部、附肢分節;循環、生殖、排泄等系統均較環節
動物復雜高級,這可能是澄江化

Most researchers working in rock field proposed that the hopkinson system be a ideal dynamic - loading equipment and the brazilian disc be a novel specimen. according to the above, this paper suggests a new method to test the dynamic strength and dynamic fracture toughness, firstly leads the cracked chevron notched brazilian disc ( ccnbd ) which was recommended by international society for rock mechanics ( isrm ) in 1995 in testing dynamic fracture toughness, which brings in a new way in dynamic testing for rock. it is expected that the work of this dissertation will provide important basis for the further research and application of mechanical behavior of rock
