The first half of the chapter begins with the introduction of three common viewpoints over the two kinds of theories, followed by deep investigation and description of some biased nature in them, then comes up with the conclusion that we must draw a clear distinction between what was said by Marx himself and what has long been accepted as dogmatical statements. The later half of chapter introduces various understandings to the theory of three social orders evoked by the discussion of economic social formation, points out the drawbacks of and the author"s disproval to the idea that economic social formation only exists in a definite historical period. This chapter is to deepen the understanding of Marx" theory of three social orders through the discussion of the other two important theories related to it.

Simulation results verify that insulated board can effectively protect the heat from transferring into the foundations, and the frozen table is always around the lower bottom of the boards; the position of the frozen table with insulated boards is higher than that of without; the embank- ment formation has a better effect on the center of embankment, the shoulder and toe of the roads than others; after consideration of the construction effect, the best lay out of the insulated boards is higher than the position of natural ground surface to 0.3-0.6 m; this formation of the embankments is the right effective constructer to be used in the permafrost on the Qinghai-Tibet railway.

通过数值模拟可知：保温板能够有效地阻止热量由路基面向下传入地基中，使0℃等温线始终在保温板底层；复合路基多年冻土上限的位置要比无保温板时的高；该结构形式对路基中心、路肩和坡脚下的多年冻土上限抬升的综合效果更好；考虑施工条件后，复合路基在保温板铺设距离天然地面之上0.3~0.6 m对于路基稳定性最为有利；该路基结构形式为青藏铁路多年冻土区路基的理想结构形式，有利于克服全球变暖的影响。

The evolution of orogenic zone,gold ore-formation and its dynamic mechanism are studied and the new viewpoint is put forward that thermal stress is a main controlling factor in metamorphism,formation ,evolution of structure and ore-forming geodynamic environment. The critical condition of fluid convection in porous equal medium and the new conclusion is reached first that the thickness of structural layer and temperature gradient are main factors influencing fluid convection andtransport of ore-forming matters in additional to physical properties of rocks. According to the conclusion some mechanisms such as the transform from compressive type to tensile one of erogenic zone,transport and accumulation of ore-forming matters such as gold and so on and many ore-forming temperature values are interpreted qualitatively.
