以南川宏能煤业(原半溪矿)矿井西翼K1煤层为研究对象,利用自主研制的含瓦斯煤热流固耦合三轴伺服渗流实验装置,进行了不同含水状态下的含瓦斯煤加卸载试验研究。研究结果表明:(1)随含水率增加,加卸载煤样的承载强度、残余强度、变形模量都呈现降低趋势,而轴向应变、径向应变、体积应变及侧向膨胀率均呈增加趋势。(2)加卸载过程中煤样甲烷有效渗透率变化与煤样损伤变形演化相对应,但存在明显的滞后现象;煤样破坏前,含水率越高,甲烷有效渗透率越小;煤样破坏后,含水率越高,甲烷有效渗透率反而越大。(3)随含水率增加,加卸载煤样破坏程度增大,裂隙发育增多,形变量增大,煤样加卸载过程中的总能量和耗散能也增加,而弹性能却减小。

本文以原子物理学中电子按能级分布理论为基础,提出一个关于金属磁性的新的巡游电子模型:在形成金属的过程中由于受到电子间泡利排斥力的作用,Fe,Ni,Co原子的大部分4s电子进入3d轨道,只有一少部分4s电子成为自由电子;最外层3d轨道的电子有一定概率在离子实间巡游,形成巡游电子;其余的3d电子为局域电子.因此,由Fe,Ni,Co金属的平均原子磁矩实验值2.22,0.62和1.72μB,计算出Fe,Ni,Co金属中平均每个原子贡献的自由电子数目为0.22,0.62和0.72,从而解释了为什么Fe,Ni,Co金属的电阻率依次减小.应用这个模型计算出的平均每个原子的3d电子数为7.78,9.38和8.28,与金属能带论计算结果 (7.4,9.4和8.3)比较接近,但是本文的方法更加简单、有效,易于理解.这为进一步澄清金属与合金的价电子结构提供了新思路.

汽油空气自热重整制氢是解决质子交换膜燃料电池 (PEMFC)氢源的重要途径。汽油中组分复杂 ,特别是碳原子数、分子结构相差很大时 ,各组分生成焓、汽化热相差很大 ,热力学分析表明 :重整难易有较大差别 ,重整规律各异 ;另一方面 ,它们重整特性又有相似的一面 ,理论氧碳摩尔比均接近于 0 3 1。以正辛烷自热重整反应作为模型反应 ,发现重整过程O2 C、H2 O C都显著影响产氢率 ,高水碳比时产品气废热能否尽量回收也是一个重要因素。理论上 ,在O2 C =0 5、H2 O C =2 0时存在最优氢产率 2 1mol molC ,这时可以得到 4 0mol%的氢气。在本所开发的GH12汽油重整优质催化剂上 ,以固定床反应器模拟正辛烷自热重整反应过程 ,发现实验结果与理论分析吻合良好。据此提出了汽油制氢合理的工艺路线。
