Chapter 2Secondly, by the modification of an catenated MOF named IRMOF-15, two new IRMOFs were designed that show largely improved methane storage capacity, which exceed the DOE target and give comparable values to the available MOF (PCN-14) with highest methane storage capacity on volume basis, but much higher values on weight basis.
与迄今具有最大甲烷存储量的MOF材料PCN-14相比，新设计的互穿MOF材料，以体积分率为标准时，均超过了PCN-14中甲烷的存储量；而以质量分率为标准，远大于PC N-14中的甲烷存储量。

Animals received low-frequency, low volume ventilation in group H group H+G, tidal volume 10 ml/ kg, breathing rate 25 bpm to achieve hypercarbonic acidosis. The target value of PETCO2 was 75-85 mm Hg. This value was maintained for 5 minutes. The animals then were ventilated normally to make the PETCO2 return to 40-50 mm Hg. Animals were injected with 0.3 mg/kg glybenzcyclamide 10min before achieving hypercarbonic acidosis with hypoventilation in group H+G.
