[[abstract]]本研究將建立固態硼氫化鈉錠水解產氫系統，並求得Ru/Al2O3觸媒之動力學參數。為了使產氫系統之儲氫量提高，先建立系統數學模式並分析影響系統之最重要變數。系統中，利用蠕動式幫浦將進料水量注入至固態硼氫化鈉錠，並且利用多孔不鏽鋼膜片當作水的分散器。固態硼氫化鈉錠為硼氫化鈉與觸媒粉末壓製而成，直徑為1.5 cm厚度為0.2 cm。系統的設計變數與操作變數為：硼氫化鈉與觸媒比例、燃料錠的孔隙度、操作溫度與進料水量。由靈敏度分析結果得知，影響系統儲氫量最重要的變數是進料水量與操作溫度 ...

Effects of heating rate on fast pyrolysis of cut filler of cigarette [PDF]
, 2016 为考察升温速率对卷烟烟丝快速热解行为的影响,采用热重-质谱联用技术对卷烟烟丝在不同升温速率(200 K·min~(-1)~800 K·min~(-1))下的热解特性进行研究,并建立了不同升温速率下卷烟烟丝的快速热解动力学模型。结果表明:(1)随着升温速率的升高,烟丝各主要成分热分解温度区间的叠加程度、热解速率以及释放特性指数均呈递增趋势,且有不同程度的热滞后现象。(2)引入升温速率校正因子的动力学模型能够克服热滞后所引起的动力学参数偏差,可以更好地预测不同升温速率下卷烟烟丝的快速热解行为。(3 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Chemically self‐charging aqueous zinc‐ion batteries (AZIBs) have emerged as promising candidates for energy storage technologies owing to their environmental autonomy and structural simplicity. Nonetheless, the self‐charging performance is significantly compromised by the limited potential difference between cathodes and oxygen, as well as the

Shuitu Baochi Xuebao, 2005 用草酸、草酸钠、柠檬酸和柠檬酸钠作为活化剂，加人不同含磷水平土壤中，通过室内培养试验和分析，结果表明：(1)0．1M草酸和0．1M柠檬酸都有一定的活化土壤磷素的作用，草酸作用最为显著。而相同浓度的草酸钠和柠檬酸钠未显示对土壤磷素的活化效果。(2)对土壤磷素的活化作用，草酸随其浓度的增加而增强，而柠檬酸活化土壤磷的能力有限。(3)柠檬酸在加人的6h之内，对活化土壤速效磷作用明显；而草酸在加人的48h之内，对活化土壤速效磷有十分显著的作用。无论是柠檬酸还是草酸，在其对土壤速效磷发挥活化作用期间 ...
