To search for potential energetic materials with large energy density and acceptable thermodyna-mics and kinetics stability,twelve derivatives of 4-nitro-5-(5-nitro-1,2,4-triazol-3-yl)-2H-1,2,3-triazolate (named A～L) are designed and analyzed by using density functional theory (DFT) calculations at the B3LYP/6-311G**level of theory.The molecular heats of formation (HOF),electronic structures,impact sensitivity (H50),oxygen balance (OB) and density (ρ) are investigated by isodesmic reaction method and physicochemical formulas.Furthermore,the detonation velocity (D) and detonation pressure (P) are calculated to study the detonation performance by Kamlet-Jacobs (K-J) equation.These results show that new molecule J (H50 =36.9 cm,ρ =1.90 g/cm3,Q =1912.46 cal/g,P =37.82 GPa,D =9.22 km/s,OB =0.00),compound A (H50 =27.9 cm,ρ =1.93 g/cm3,Q =1612.93 cal/g,P =38.90 GPa,D =9.19 krn/s) and compound H (H50=37.3 cm,ρ =1.97 g/cm3,Q =1505.06 cal/g,P =37.20 GPa,D =9.01 km/s) present promising effects that are far better RDX and HMX as the high energy density materials.Our calculations can provide useful information for the molecular synthesis of novel high energy density materials.

以家兔为研究对象,探讨两色金鸡菊和芳香新塔花两种提取物对家兔颈总动脉血压、心率的影响,并比较其异同.试验将两色金鸡菊和芳香新塔花提取物各设低、中、高3个浓度组,采用生物信号系统采集、记录家兔颈总动脉血压,比较加药后各组家兔舒张压、收缩压和心率的变化.结果表明:两色金鸡菊和芳香新塔花提取物3个浓度组均能使家兔颈总动脉收缩压、舒张压明显下降,二种提取物对舒张压的影响比对收缩压的影响更明显,但对心率抑制影响并不明显.与芳香新塔花提取物相比,同剂量的两色金鸡菊提取物对家兔颈总动脉血压抑制更为明显.说明两色金鸡菊提

空气质量状况直接影响着人们的身心健康,空气污染治理一直是一个广受争论的热点问题.本文基于2015～2020年江西省各地级市主要污染物浓度和气象数据,采用时间序列与随机森林模型,深入分析江西省各地级市的空气质量状况及其影响因素,得到以下结果:(1)从整体角度来看,2015～2020年间江西省城市的空气质量一直处于优良状态,且呈现出不断提高趋势.(2)从季节角度来看,各城市每年的AQI值呈现倒“山”形分布,各污染物浓度变化特征明显,除O3外其他污染物浓度大致呈现“冬秋高、夏秋低”的特点,其中萍乡市的变化最为突
传统SIR模型的初始参数是随机设定的,同时状态转换之间没有考虑实际网络拓扑结构,导致传播收敛效果与实际不一致.为了解决该问题,本文提出一种基于演化博弈和网络拓扑结构改进的SIR模型.改进的模型首先通过演化博弈方法确定影响因子,接着根据影响因子确定好SIR模型的初始感染率参数,然后根据网络拓扑结构调整状态之间的转换概率.在真实社交网上进行疫情及舆情仿真传播实验,研究结果表明:疫情与舆情传播主要受网络拓扑结构影响,在不考虑网络拓扑的情况下,增加政府和媒体管控力度以及个人名誉损失可以延缓传播时间.
