作者 高育清 《中国管理信息化》 2010年第3期57-58,共2页
债券价值受多种因素的影响,假定在整个流通期间投资者要求的报酬率保持不变,则债券的价值主要受到期时间的影响。对于平息债券而言,债券到期时间对于债券价值的总影响表现为:溢价发行债券,其价值随债券到期时间的临近而减少;折价发行债... 债券价值受多种因素的影响,假定在整个流通期间投资者要求的报酬率保持不变,则债券的价值主要受到期时间的影响。对于平息债券而言,债券到期时间对于债券价值的总影响表现为:溢价发行债券,其价值随债券到期时间的临近而减少;折价发行债券,其价值随债券到期时间的临近而增加;平价发行债券,其价值不随债券到期时间的临近而变化,始终等于面值。但在两个付息日之间,不管是采用溢价发行、折价发行的债券,还是平价发行的债券,其价值都是曲线上升的,然后随着本期利息的支付,其价值骤然下降。 展开更多

作者 王洪芳 《四川省公安管理干部学院学报》 1999年第2期29-30,共2页
所谓累犯构成的时间界限是指构成累犯(在我国刑法中.累犯包括一般累犯与危害国家安全累犯两种,后者不存在时间界限这一问题,故本文所指累犯均指一般累犯。)的前罪与后罪的间隔期限。亦即后罪的发生时间问题。

AIM: TO re-evaluate the recent clinicopathological fea- tures of remnant gastric cancer (RGC) and to develop desirable surveillance programs.METHODS: Between 1997 and 2008, 1149 patients underwent gastrectomy for gastric cancer at the Department of Digestive Surgery, Kyoto Prefectural Uni- versity of Medicine, Japan. Of these, 33 patients un- derwent gastrectomy with lymphadenectomy for RGC. Regarding the initial gastric disease, there were 19 patients with benign disease and 14 patients with gas- tric cancer. The hospital records of these patients were reviewed retrospectively. RESULTS: Concerning the initial gastric disease, the RGC group following gastric cancer had a shorter in- terval [P 〈 0.05; gastric cancer vs benign disease: 12 (2-22) vs 30 (4-51) years] and were more frequently reconstructed by Billroth- I procedure than those fol- lowing benign lesions (P 〈 0.001). Regarding recon- struction, RGC following Billroth-]_l reconstruction showed a longer interval between surgical procedures [P 〈 0.001; Billroth-11 vs Billroth- I : 32 (5-51) vs 12 (2-36) years] and tumors were more frequently associated with benign disease (P 〈 0.001) than those following Billroth- I reconstruction. In tumor location of RGC, after Billroth- I reconstruction, RGC occurred more fre- quently near the suture line and remnant gastric wall. After Billroth- 1I reconstruction, RGC occurred more fre- quently at the anastomotic site. The duration of follow- up was significantly associated with the stage of RGC (P 〈 0.05). Patients diagnosed with early stage RGC such as stage Ⅰ-Ⅱ tended to have been followed up almost every second year. CONCLUSION: Meticulous follow-up examination and early detection of RGC might lead to a better prognosis. Based on the initial gastric disease and the procedure of reconstruction, an appropriate follow-up interval and programs might enable early detection of RGC. 展开更多
