Results PCT of bacterial infection group was significantly higher than that in non-bacterial infection group (χ^2=0. 05, P〈0.05). With increase in the concentration of PCT, its sensitivity was lower, but its specificity was higher. With PCT���1.5 ng/ml as the cutoff point for positive, Youden's index and agreement were highest.
随血清PCT浓度升高,其对危重病人感染诊断的敏感度降低、特异度增高;以1.5ng/ml为阳性诊断标准时,Youden指数和诊断符合率分别为0.65和83.0%,明显高于以1ng/ml和2ng/ml为阳性诊断标准时。

The analytic results obtained from the PCT evaluations revealed that the most limiting accident was the case with a break at the Main Steamline Outside Containment. Its PCT was 1289.15 ℉, which is much below the upper temperature limit of 2200℉ set by the nuclear regulatory authority. The most limiting accident for the minimum water level measured outside the core shroud is the case with a break at the High Pressure Core Flooder Line, the minimum water level drops to 18.4 ft. For this case, even though the water level has dropped to 11.6 ft below the top of the active fuel, the reactor core was still completely covered by the two-phase water.
分析结果显示,对燃料护套最高温度而言,最严重之事故为围阻体外主蒸汽管路破口,其燃料护套最高温度为1289.15 ℉,此温度远在法规10CFR50.46所定之限值 2200 ℉以下;对反应炉最低水位而言,则最严重之事故为高压注水系统管路破口,反应炉降水区最低水位降至18.4 ft,约在有效燃料顶部以下11.6 ft,然而炉心内部仍为双相饱和流体所完全覆盖。
