Abstract ：
在自主设计的长度和内径均为25 cm的圆柱形容器中,开展了不同掺氢比(x)的氢气-甲烷-空气泄爆实验.实验结果表明:X对容器内部超压有显著影响,容器内共出现三类压力峰值(p1、p2、p3).p1是泄放速率超过了燃烧产物生成率导致的,并出现在x＜0.9的实验中,其幅值几乎不受x的影响;P2由声学振荡产生并且出现在0.45≤x≤0.9的实验中;p3是火焰燃烧面积达到最大值产生,仅出现在X=1的情况下.声学振荡造成的超压峰值随着x单调增加,在发生声学振荡时,火焰表面会出现周期性的细小胞格,并且声学振荡的频率与细小胞格出现的频率相近.X＜0.3时,容器内只存在一个压力峰值p1;X＞0.3时,容器内最大超压随着x单调增加.x＞0.15时,外部爆炸的最大超压也随着x的增加而增加.

Abstract ：
The explosive properties of methane-ethane mixtures with different concentrations and ethane proportions (phi value) were studied in a 1 m(3) spherical vessel, along with the inhibitory effects of N-2 and CO2. The results indicate that when the concentration of the total gas mixture was 10%, P-max and (dp/dt)(max) first increased and then decreased with the increase of phi. In contrast, for total gas mixture concentrations of 8% and 12%, P-max and (dp/dt)(max) showed a single change. Under the test conditions of this experiment, P-max reached its maximum value when the total gas mixture concentration was 10% and phi = 0.1. The explosion suppression of gas mixtures showed that both N-2 and CO2 could significantly reduce P-max and (dp/dt)(max) when their volume fractions increased to 9%. While the continued addition of N-2 and CO2 did not significantly reduce P-max and (dp/dt)(max), it further delayed the arrival time of the peak, with a greater magnitude of delay for CO2. Regarding the flame propagation process, the same volume fraction of CO2 can reduce the flame propagation speed more effectively, and the bottom of the flame is more significantly affected by buoyancy instability.

Abstract ：
To mitigate the damage caused by methane explosions, this paper conducts experiments on methane explosion suppression by CO2 and air (for comparison)-driven NaHCO3 powder using a 1 m3 spherical explosion test system. The results indicate that the explosion suppression effect was gradually enhanced with the increase of NaHCO3 powder concentration. Driven by air, as the concentration of NaHCO3 powder increases, the flame becomes darker and the propagation speed slows down. After adding 700 g/m3 NaHCO3 powder, methane cannot be ignited. The significant concentration range for explosion suppression efficiency is between 200 g/m3 and 500 g/m3. Driven by CO2, the flame evolves more slowly, the flame shape is more irregular, and the flame brightness is lower. Compared with air propulsion, the required NaHCO3 powder for complete explosion suppression is reduced by 100 g/m3, and the required NaHCO3 for related explosion suppression effects is reduced by 100 g/m3. The explosion suppression effect of CO2 driven NaHCO3 powder is superior to the sum of the suppression effects of high-pressure CO2 gas injection and air driven NaHCO3 powder. The explosion suppression effect of CO2 enables NaHCO3 powder to fully decompose and exert the best inhibitory effect; The CO2 generated by the decomposition of NaHCO3 can further enhance the suppression effect of CO2, and the two can thus produce a synergistic inhibitory effect.

Abstract ：
A crucial industry for improving society's sustainable development is the power sector. To address issues with the ineffectiveness of electric power emergency response during emergencies and the unclear division of duty among emergency subjects. A prefecture-level city power supply company to respond to the "In-Fa" typhoon, for example, to build a "1 + N" two-level emergency rapid response unit. Furthermore, it is proposed from the emergency response, emergency coordination, emergency material reserves, etc., to build a "full-chain" type of power emergency quick reaction system. Case studies have revealed that the quick response system's emergency combat capability, catastrophe preventive and mitigation capability, and emergency security capability have all improved. The construction of a "full-chain" type of power emergency rapid response system specialized and standardized the power emergency response system and provided a reference basis for the power industry's emergency response.

Abstract ：
为完善和推动事故致因理论的发展,提高事故防控水平,在对信息流事故致因模型(IFAM)和事故致因2-4模型(24Model)理论基础、组成要素和分析过程对比研究的基础上,通过实例分析辨识二者之间的异同.研究结果表明:IFAM与24Model都有较强的理论基础,部分组成要素存在对应关系,但原因类别划分存在差异.IFAM以信息流和组织为研究对象,研究过程相对复杂,更适用于分析单起事故;24Model以组织为研究对象,事故原因模块通用性和逻辑性强,适用于分析单起或某类事故.在实际应用中,IFAM与24Model均可用于事故调查分析和事故分级定责,具有一定的理论和实践价值.IFAM通过信息流表征事故致因,直观描述组织外部原因因素,但对个体能力的深入研究欠缺;而24Model认为组织外部因素需要通过组织内部原因模块的欠缺体现,认为个体能力是引发事故的间接原因并进行细致分析,但对组织间相关关系的探究欠缺.研究结果可为事故预防工作提供新视角和理论支撑.

Abstract ：
The explosion venting experiments of hydrogen-air premixed gas were carried out in a 1-m3 cuboid container. The effects of the obstacles parallel to the vent on the structural response of the container during the explosion venting were investigated. The internal overpressure and acceleration of the vessel wall were captured by acceleration and pressure sensors, respectively. The time-frequency distributions of pressure and acceleration were obtained by a Short-Time Fast Fourier Transform. The effects of obstacles on the dynamic structure response were studied by analyzing the internal overpressure, vibration acceleration, and high-speed videos. With the increase of obstacles, the maximum overpressure and vessel vibration increased, and the maximum overpressure and maximum vibration acceleration appeared earlier. The vibration signals had two dominant frequencies, 300-600 Hz and 900-1200 Hz. The low-frequency vibration (300-600 Hz) was induced by acoustic oscillation of the internal pressure. The high-frequency vibration (900-1200 Hz) was a container resonance triggered by the coupling of the flame and the acoustic wave. As VBR increased, the duration of high-frequency oscillations decreased gradually; the increase of obstacles would weaken the high-frequency structural response of the container. The results can guide the design of hydrogen explosion protection and mitigation measures.

Abstract ：
为提升高校实验室气瓶安全管理水平,本文采用"2-4"模型(24 Model),对5起高校实验室气瓶事故操作人员的不安全动作原因、习惯性行为原因、安全管理体系原因和安全文化原因进行分析,并提出事故预防措施.研究表明,高校实验室气瓶事故的直接原因主要为操作人员违章操作,实验室管理人员未全程监督管理试验过程,事故的间接原因是实验操作人员以及实验室管理人员的安全知识不足、意识不高、习惯不佳,根本原因是高校实验室缺失或未执行实验气瓶管理和操作的相关程序;根源原因是师生对安全文化元素的理解不到位.本文根据分析的原因提出从个人和组织层面提出预防措施,从控制不安全动作、完善安全管理体系、建设安全文化等三方面入手,具有较强的实用性和借鉴意义.
