And it has given the effects of the all factors on the runoff by 1D river networks mathematical model. Due to the natural and artificial influences, the water-sediment transport has greatly changed. It is characterized by marked decrease in runoff and sediment diverted from these outfalls and increase in water-sediment transport of main stream. The key factors causing these changes are aggradation of the three outfalls channels and Jingjiang river cutoff work.

结果表明，受自然因素和人为因素的影响，荆江－洞庭湖江湖水沙输移有了较大调整变化，主要表现为三口分流分沙大幅度减小，干流水沙输移增加；江湖关系变化的主要因素是三口分流道的淤积萎缩和荆江裁弯。

A novel design method is put forward and the cutoff filters with depolarization at incidence angle of 45° are achieved.

由于这种设计的截止区和透射带带宽常嫌不足，故提出了展宽截止区和透射带的方法。

Fluorescein isothiocyanate labeled polyclonal goat antihuman immunoglobulin antibody was added, and flow cytometer was used to detect bead-platelet-associated autoantibodies-antihuman immunoglobulin antibody complex. Results The fluorescene ratio of four monoclonal antibodies was significantly different (P.01) between the idiopathic thrombocytopenic purpura patients and either the non-ITP patients or the normal controls. If the upper limit of normal control was set as cutoff value, ratios of greater than 1.37, 1.24, 1.48 and 1.19 were considered positive for the four monoclonal antibodies respectively. The flow cytometric bead assay had an overall sensitivity of 73.17% and a specificity of 94.29%. The overall sensitivity was significantly higher (P.05) than that of modified indirect MAIPA and that of using single antibody.

结果 特发性血小板减少性紫痕组4种羊抗荧光强度比值与非ITP血小板减少组和正常对照组有显著性差异(P.01)；若将ITP组患者4种羊抗荧光强度比值分别大于正常对照组上限1.37、1.24、1.48和1.19判断为阳性，则流式微球技术检测血小板特异性自身抗体的敏感性为73.2%，特异性为94.3%；4种羊抗联合检测总体敏感性明显高于改良间接单抗特异的血小板抗原固定试验(P.05)，且大于各单个抗体检测敏感性。

结果 特发性血小板减少性紫癜组4种单抗荧光强度比值与非ITP血小板减少组和正常对照组有显著性差异（P＜0.01）；若将ITP组患者4种单抗荧光强度比值分别大于正常对照组上限1.37、1.24、1.48和1.19判断为阳性，则流式微球技术检测血小板特异性自身抗体的敏感性为73.17%，特异性为94.3%；4种单抗联合检测总体敏感性明显高于改良间接单抗特异的血小板抗原固定试验（P＜0.05，且大于各单个抗体检测敏感性。

Also, some patients with chronic hepatitis B have widely fluctuating HBV DNA levels that may vary from undetectable to 2,000,000 IU/ml.117 Thus, serial monitoring of HBV DNA levels is more important than any single arbitrary cutoff value in prognostication and in determining the need for treatment.

而且，许多患有慢性乙型肝炎的患者，HBV DNA水平波动的幅度很大，可从测不出到10'7copies/ml之间变动。因此，为了预测病情和确定是否有治疗需要，对HBV DNA水平的连续检测比任何武断确定的单个临界值更为重要。

"If therefore", argues Bellarmine we can offer our prayers and our satisfactions in behalf of those detained in purgatory, because we are members of the great body of Christ, why may not the Vicar of Christ apply to the same souls the superabundant satisfaction of Christ and his saints--of which he is the dispenser?

" "因此，如果"，认为贝拉明（德indulgentiis ，十四）"我们可以提供我们的祈祷和我们满意的代表那些被拘留在炼狱，因为我们是成员的伟大基督的奥体，为什麼可能不是牧师基督适用於同样的灵魂满意的过剩是耶稣和他的圣人-他是在配药？
