It is shown that the generation of the PA effect results from two kinds of contribution only. One is the contribution of so called"thermal piston"--the gas boundary layer adjoining the heated sample which expands cyclically and pushes the rest gas just like piston. The compressing process of it is comfirmed to be isochoric. And the other is that of"mechanical piston"--the thermally expansive sample itself, the compressing process of which is found to be polytropic with a index of (2-〓).

一即是被称为&热活塞&的与材料受热表面相邻的边界层气体周期性热膨胀产生的压缩，其是定容过程；另一是被称为&机械活塞&的材料本身热膨胀产生的压缩，其是多变过程，多变指数为2-〓，γ为绝热压缩因子。

结果表明，17#样品与(CATA3_SOYBN)Catalase 3的匹配分数是80，匹配显著，同时分子量和等电点pI比较接近，因此可以认为17#样品是(CATA3_SOYBN)Catalase 3；29#样品与ATP synthase beta chain的匹配分数是191，匹配显著，同时分子量和等电点pI比较接近，可以认为29#样品是ATP synthase betachain；53#样品和43#、45#、52#样品的肽段峰一样，应该是同一类蛋白。

毛细管出口、工作电极和光纤的相对位置会影响样品与电生试剂之间的混合和光的收集效率，影响到系统的灵敏度和分离效率，因而对三者之间的相对位置进行了优化。

The oxide formed on NbSi2 at 1023 K consists of Nb2O5 and minor SiO2. The Nb2O5 is lose and nonprotective, which spalls from the sample during oxidation. The oxidation kinetics of all the NbSi2 samples at 1023 K follows a linear law. The oxidation rate is intrinsically determined by the reaction rate between the matrix and the oxygen in air, which in turn is determined by the exposure area of the sample.

无论是单晶还是多晶样品，氧化产物均为 Nb2O5和SiO2，生成的Nb2O5易剥落，样品的氧化动力学曲线均呈直线规律，证明NbSi2的氧化过程是一种本征无保护条件下氧元素与基体元素直接反应的过程。

Through the tests on gas driving water and water driving gas, the flow law of gas and water was real-time observed. Mainly based on the test of water driving gas as an example, the development of molding coal sample and NMR triaxial osmoscope was demonstrated. The experiment process of water driving gas and parameters were demonstrated. NMRI images of molding sample in horizontal cross-section along the driving direction were obtained by NMRI instrument. The results from images were analyzed and compared. Some novel laws were obtained as the following:(1) the leading edge of water driving has inconsistency. This certified the important previous conclusion that the storage of methane mainly was absorbed in inner surface of pore from NMRI technique;(2) the existence of dominant driving pathway was tested and the way kept almost fixed. The pathway is apt to exist in the edge of coal samples where pore and fracture fully develop;(3) the variation of water flow determines the transport velocity of leading edge of water driving and it has lag effect;(4) the effectiveness of the first driving is better than the second driving;and (5) the subsequence of water driving gas are from trunk fractures to branch fractures, then to branch pores.

主要以水驱气NMRI试验为例，详细介绍了核磁共振三轴渗透仪和型煤试件的研制，并重点阐述了水驱气试验过程和相关参数，利用NMRI技术实时观测得到了不同时间沿驱替方向型煤试件水平剖面的NMRI成像图，最后对试验结果进行了比较分析，揭示了一些新的规律认识：(1)水驱替前缘具有不一致性，从NMRI试验角度验证了前人甲烷类气体赋存形式主要以吸附在孔隙内表面为主的重要结论；(2)煤试件存在优势驱替路径，且这种优势路径在驱替过程中基本保持不变，水驱气的优势驱替路径易产生在煤试件边缘，即煤孔隙裂隙发育区；(3)水驱流量变化决定了水驱前缘的运移速度，且对水驱气效果具有滞后效应；(4)水驱气初次驱替效果好于二次驱替效果；(5)水驱替气的顺序为：主要大裂隙—周边裂隙—周边孔隙。
