1) Gasoline density
汽油密度
1.
For it is difficult to get the carbon-hydrogen ratio of gasoline during themeasuring of petrol fuel consumption with carbon balance method, according to therelationship between carbon-hydrogen ratio and gasoline density, a simple mathematicalmodel is derived as a new method for the measuring of gasoline carbon-hydrogen ratio inpractice.
鉴于用碳平衡法测量汽油机耗油量时汽油碳氢质量比难以测定，根据汽油碳氢质量比与汽油密度的对应关系，导出了汽油碳氢质量比与密度关系的简单数学模型，为汽油碳氢质量比的测定提供了一种新的方法。
2) gasoline-tight
汽油密的
3) steam density
蒸汽密度
1.
Study on the mathematical model of steam density and the steam flow measurement on line to realize temperature and pressure compensation;
蒸汽密度数学模型在线温压补偿蒸汽流量分析
5) Vapor density
水汽密度
6) sealed gasoline tank
密闭汽油罐
1.
As some uncertain factors of sealed gasoline tank leaking pool fire quantitative risk assessment can not be confirmed, the hazard result from pool fire accident might be uncertain.
分析了汽油的危险特性及池火灾的主要特点,针对密闭汽油罐泄漏池火灾定量风险评估中不确定因素导致事故造成的危害结果不确定性问题,建立了密闭汽油罐泄漏池火灾风险评估模型,提出了一种基于随机抽样推测法的不确定性处理方法,计算了池火灾热辐射伤害范围,并通过统计分析确定人员死亡区域遵循的分布函数,进而确定该区域的大小,对于定量评估池火灾事故风险具有重要意义。
