recurrence interval
2.When comparing them with the real recurrence intervals of paleoearthquakes,we found that they are quite coincidence,showing that the suggested calculating method can be used to estimate the recurrence interval of earthquakes in active fault zone as well as the seismic risk evaluation.
3.Based on studying selection of flood standard in the country, by all-round thor ough research in basic data, estimation methods, structure layout, flood release structures, dam breaking flood advent and its risk, the flood standard rationality for Ertan Hydroelectric Plant are expounded and proved to select the recurrence interval thousand years for design and five thousand years for check.
4.Results Tumor recurrence was markedly late in patients with dendritic cells count≥20 and positive lymphocytes infiltration(group A, n =17) as compared with those who did not meet both criteria simultaneously(group B, n =27), with a median interval of 21 6 months for group A and 4 1months for group B( U value=105 5, P =0 009).
5.Thirty-four cases were divided into two groups,20 cases received the interval gradual complete embolization of BAE in Group A,the other used the traditional embolization in Group B.Results:The overall effective rate and recurrence rate for 1 year were 82.4%(28/34),29.4%(10/34),respectively.
