为研究民用机场消防指挥员决策能力,根据专家意见及相关规章、文件的规定,筛选出文化素质、身体素质、心理素质等18项影响机场消防指挥员决策能力的要素,并采用问卷调查的方式进行调研。运用SPSS 21.0对问卷进行信度分析、效度分析及因子分析,确定民用机场消防指挥员决策能力指标体系。根据该指标体系构建民用机场消防指挥员决策能力结构方程模型,运用Amos 17.0计算各变量的路径系数,进而得到各指标的权重,避免了人为打分方法确定权重的主观性。研究结果为分析民用机场消防指挥员决策能力提供更加准确、合理、可信的评价方法。 相似文献

Hydraulic characteristics of an anaerobic baffled reactor as onsite wastewater treatment system 总被引:2,自引:0,他引:2
The feasibility of using anaerobic baffled reactor(ABR)as onsite wastewater treatment system was discussed.The ABR consisted of one sedimentation chamber and three up-flow chambers in series was experimented under different peak flow factors(PFF of 1 to 6),superficial gas velocities(between 0.6 and 3.1 cm/hr)and hydraulic retention times(HRT)(24,36 and 48 hr).Residence time distribution(RTD)analyses were carried out to investigate the hydraulic characteristics of the ABR.It was found that the PFF resulted in hydraulic dead space.The dead space did not exceed 13% at PFF of 1,2 and 4 while there was 2-fold increase(26%)at PFF of 6.Superficial gas velocities did not result in more(biological)dead space.The mixing pattern of ABR tended to be a completelymixed reactor when PFF increased.Superficial gas velocities did not affect mixing pattern.The effects of PFF on mixing pattern could be minimized by higher HRT(48 hr).The tank-in-series(TIS)model(N=4)was suitable to describe the hydraulic behaviour of the studied system.The HRT of 48 hr was able to maintain the mixing pattern under different flow patterns,introducing satisfactory hydraulic efficiency.Chemical oxygen demand(COD)and total suspended solids(TSS)removals under all flow patterns were achieved more than 85% and 90%,respectively.The standard deviation of effluent COD and TSS concentration did not exceed 15 mg/L. 相似文献

The feasibility of using anaerobic ba ed reactor (ABR) as onsite wastewater treatment system was discussed. The ABR consisted
of one sedimentation chamber and three up-flow chambers in series was experimented under di erent peak flow factors (PFF of 1
to 6), superficial gas velocities (between 0.6 and 3.1 cm/hr) and hydraulic retention times (HRT) (24, 36 and 48 hr). Residence time
distribution (RTD) analyses were carried out to investigate the hydraulic characteristics of the ABR. It was found that the PFF resulted
in hydraulic dead space. The dead space did not exceed 13% at PFF of 1, 2 and 4 while there was 2-fold increase (26%) at PFF of
6. Superficial gas velocities did not result in more (biological) dead space. The mixing pattern of ABR tended to be a completelymixed
reactor when PFF increased. Superficial gas velocities did not a ect mixing pattern. The e ects of PFF on mixing pattern could
be minimized by higher HRT (48 hr). The tank-in-series (TIS) model (N = 4) was suitable to describe the hydraulic behaviour of
the studied system. The HRT of 48 hr was able to maintain the mixing pattern under di erent flow patterns, introducing satisfactory
hydraulic e ciency. Chemical oxygen demand (COD) and total suspended solids (TSS) removals under all flow patterns were achieved
more than 85% and 90%, respectively. The standard deviation of e uent COD and TSS concentration did not exceed 15 mg/L. 相似文献

为研究民用机场消防指挥员决策能力,考虑测评指标分为定性与定量2类,且指标存在模糊性的特点,建立基于云模型的民用机场消防指挥员决策能力测评方法。根据相关规章规定、专家意见和问卷调查结果,确定测评指标体系,并依据云模型原理建立定性到定量的测评转换模型,将指标的定性测评转化为直观的定量评价;最后,根据云模型的期望、熵、超熵,评价民用机场消防指挥员决策能力水平。研究结果表明:利用基于云模型原理构建的定性与定量测评转换模型进行决策能力测评,所得测评结果能够体现评价指标模糊性和随机性的特点,评估结果更加直观且贴近实际情况。 相似文献
