Discussion on Storage and Layout of LPG under Low Temperature and Atmospheric Pressure 低温常压LPG储存及布置的探讨
According to occurrence conditions of aquiferous zone, groundwater conducting zone and storage segment of water-resistance for lower group coal, seven types criterion models of mining under high pressure was concluded and corresponding groundwater hazards controlling policy was put forward. 根据显水带、导水带及阻水储备带相对下组煤在空间上的赋存状况,总结归纳出7种带压开采判别模型,并提出了相应的具体防治水对策。
A hydrogen storage and release capacity of 0.33& 0.37 weight at room temperature under a modestly high pressure ( 12MPa) for untreated nano-graphite samples synthesized under different conditions. 在室温(≈290K)和12MPa压力条件下对纳米石墨粉进行储放氢气性能测试,结果表明纳米石墨粉样品的储放氢量为033wt%&037wt%。
Based on a large amount of experiment by various re-searchers, the dependence of the lamp life and the emission material storage under 3 hour on-off burning cycle conditions is obtained, which is also strongly depending on the gas filling pressure. 基于不同研究者的大量实验,我们得到了在每3小时开关一次的燃点条件下,灯寿命与发射材料贮量之间的关系,此关系与充气压强有关。
Taking wellbore storage and skin effect into account, this paper studied the flow distribution in homogenous reservoir model with constant pressure outer boundary under the condition of controlled bottom pressure. 针对外边界定压的均质储层模型,研究了在控制井底流动压力状态下考虑井筒储存和表皮效应的油气井产率的变化规律。
And then, the sol rheological behavior of gelling agent, storage stability, thermal decomposition characteristics and explosive performance under static pressure have been systematically studied. 对煤矿型***胶凝剂溶胶的流变性、储存稳定性、热分解特性以及静压作用下的爆炸性能进行了系统研究。
