Effects of salinity on leaf characteristics and CO2/H2O exchange of Kandelia candel (L.) Druce seedlings
salinity mangrove cell structure
2015/3/6
Effects of salinities on leaf characteristics and CO2/H2O exchange of mangrove species Kandelia candel seedlings were studied in a pot experiment. The seedlings grown in salinity of 50‰ caused a stron...
利用TGA-51H型高温热天平、扫描电镜–X射线能谱研究了我国典型高、低灰熔点煤种煤焦–CO2/H2O气化反应过程中灰的熔融变化行为和熔融机制。研究结果表明:高温下煤中的灰主要在煤焦–CO2/H2O气化反应过程中的中、后期(碳转化率大于50%)开始发生熔融,且初始熔融部分的主要成分为Fe系硅铝酸盐矿物(如铁橄榄石、铁铝榴石等),随着煤灰的进一步熔融,熔融部分中Ca元素含量逐渐增加,大量钙系矿物的出...

流动CO2—H2O系统中方解石溶解动力学机制
CO2-H2O系统 方解石 溶解动力学
2010/11/4
利用旋转盘实验装置和高分子生物催化剂技术,笔者研究了流动CO2-H2O系统中方解石溶解动力学及其控制机制。实验发现,方解石的溶解既受到固-液界面间扩散边界层(DBL)的控制,还受到扩散边界层内CO2慢速转换反应(CO2+H2O←→H^++HCO^)的控制。然而,高CO2分压(Pco2〉0.01atm)时,溶解主要为CO2慢速转换控制,而低CO2分压(Pco2〈0.01atm)时,溶解主要为扩散为边
