无效率的

Two new data structures TOPSIS-Tree and RELIS are devised to maintain potential significant itemsets and mined results, respectively. Moreover, three optimal strategies are exploited to reduce time and space consumption of the algorithms:(1) pruning impotent nodes in the newest basic window whenever a sliding window updates,(2) promoting support threshold during mining process dynamically, and (3) adjusting pruning threshold adaptively and heuristically.

Expression rate induced by thrombin was 50.88% and PAC?1 re?expression was 54.55%. It is concluded that the ability of recovered lyophilized platelets added with reversible activation?inhibitors, DMSO and trehalose to aggregate and coagulate has showed no significant difference as compared with FPRP. The reversible activation?inhibitors can decrease CD62p expression of lyophilized platelets, and may enhance their survival ability and prolongate survival time. Therefore the efficiency of lyophilizing platelets can be improved based on this freeze?drying procedure.

添加血小板可逆性激活抑制剂，海藻糖和DMSO后的冻干血小板，其聚集活性和促凝血功能与新鲜血小板无明显差异，血小板可逆性激活抑制剂降低了冻干血小板的CD62p表达，增强了冻干血小板的生存能力，因而延长了其生存时间，因此可以该冻干方法为基础进一步提高冻干保存血小板的效率。

Abstract］ objective to evaluate the distinctive clinical value of magnetic resonance urographymru）in the diagnosis of primary ureteral carcinoma.methods to compare the accuracy of diagnosis of mru with ultrasonography,urography,retrograde ureteropyelography and ct,diagnostic imaging and progress of ureteral carcinoma were analyzed in twenty-four cases from 2000 to 2006,twenty cases had mru examinations.the original preoperative diagnostic reports of various imaging facilities were analyzed on account of the results of operation and pathology.results mru could clearly show the obstructive location of ureter.with regard to the ureteral carcinoma,accuracy of the location diagnosis was 100%.mru was superior to ulstrasonography,kub+ivp,ureteropyelography and ct we used to apply.conclusion comparing with other diagnostic imaging facilities,it has an important value in highly efficient,accurate location,safe,noninvasive and so on with mru,which can be used to show the features of primary ureteral carcinoma and has a wider scope of clinical application.

目的 探讨磁共振水成像技术在原发性输尿管肿瘤中的临床诊断价值。方法分析2000～2006年24例原发性输尿管肿瘤的影像学诊断结果，并基于术中所见和病理报告，将磁共振水成像技术20例）与超声24例）、泌尿系造影24例）、逆行造影15例）、ct(19例）的确诊率相比较。结果 mru能清晰显示输尿管的梗阻部位，定位诊断准确率为100%，梗阻病因确诊率高于b超、泌尿系造影、逆行造影和ct检查。结论与其他影像诊断方法相比较，磁共振水成像在显示原发性输尿管肿瘤特征方面具有效率高、定位准确和安全无创等重要价值，而且有更广泛的临床应用范围。

It is shown that the ADFVLN, which has lower losses, high off-design performance and reliability, is superior to the vaned nozzle as the first stage and it also has more advantages than the early AFVLN, such as lower losses and less skewed boundary layer near the inner ring ect..
