These characteristics have close relation with transgression from eastern to western . 4 . reefs undermined various and complicated diagenesis , in which cementation , dolomitization and corrosion etc . play main roles in the history of reef diagenesis 4礁岩的成岩作用具多样性和复杂性，其中泥晶化、填积、胶结、白云化和溶蚀作用最为重要。
Burial dissolution mainly developed inside the primary micropores , the partly filled intergranular porosities and the intercrystal porosities , which furthermore formed lots of enlarged pores , intergranular pores , oolimolds 埋藏溶解作用主要在粒间半充填剩馀缝隙、交代白云石的晶间孔内进行，这进一步溶蚀造就了大量超大孔隙、粒间溶孔、粒内孔、铸模孔等。
Among them , phreatic , vadose and in the middle of convection zones undergone dissolution ( especially in vadose zone ) . the mixing and upper convection zones undergone cementation . the lower convection zone remained unaltered 其中渗流、潜流和深部对流带中部以溶蚀作用为主(潜流带最强烈) ，混合带和对流带上部以胶结作用为主，对流带下部成岩作用不活跃。
All the facts above indicate that the best development era of lunan stone forest has passed by , although the height of stone pillars is still increasing at present . meanwhile , the study also shows that the maximal concentr 由于包气带强溶蚀循环带的深度有限，纯粹于土下发育的石牙、石林，其高度一般不会超过10m ，现在我们所见高度在10m以上的高大石林，是在后期厚层覆盖物的剥蚀过程中增长拔高的。
With the intermittent activity of hot fluid containing cc ^ , ferrous carbonate minerals dissolved and precipitate repeatedly many times . in addition , dissolution of shells and feldspars , decrease of chlorite and increase of kaolinite could be found 随着富co _ 2热流体多次间歇性入侵导致了含铁碳酸盐矿物的反复多次溶解和沉淀、生物介壳大量溶蚀和长石铸模孔的形成以及绿泥石消失、高岭石增加等。
The dolostones have experienced several types of post - depositional diagenetic modifications , of which dolomitization , dissolution , recrystallization and tectonic stress processes have exerted an important effect on porosity and permeability 认为该白云岩在沉积期后变化中经历了多种成岩作用改造，其中影响白云岩储集性的作用主要有白云石化作用、溶蚀作用、重结晶作用和构造应力作用，对白云岩孔渗改善起了积极作用。
Stone forest , which is a kind of rare karst geomorphology and called as pinnacle karst in other countries , refers to the forest - like landform composed of the stone pillars more than 5 meters high and resulted from longtime dissolution of limestone along joints 石林是一种稀有性的喀斯特地貌形态，是指石灰岩在长期的喀斯特作用下，沿节理溶蚀而形成的高5m以上的石柱组成的林状地貌景观，国外称为针状喀斯特或剑状喀斯特。
The rock mass is made up with rock and cracks , however , in the carst region " s the rock mass also include the hole and cave develop for corrosion . generally , the rock is impermeable , and the permeability of the rock mass depends on the permeability of cracks 岩体是由岩块及其裂隙组成的，对岩溶地区的岩体尚包括沿结构面发育而成的溶蚀孔、洞，一般来说，岩石的透水性很小，岩体的透水性主要决定于裂隙的渗透性大小。
Because f - doped increases the content of mn3 + , which is the active ion at oxido - reduction , so f - doped can increase the initial capacity , but the increased mn + intensified the jahn - teller distortion and the dissolution of mn2 + , both of which deteriorated the cyclability 表面修饰后的limn _ 2o _ 4晶粒具有良好的抗电解液溶蚀能力， mn的溶解量仅是未经表面修饰材料的1 / 2左右；虽然首次放电容量有所降低，但其循环性能优良。
For the high pressure phase equilibrium system composed of co2 , h2o , cacl2 , etc . , co2 is treated as super critical fluid truly , the volume of which is estimated by bwr state equation suitable for super critical fluid 考虑了酸液溶蚀的碳酸盐以及酸岩反应生成的二氧化碳对人工裂缝体积的影响，针对裂缝内由二氧化碳、水、氯化钙等物质组成的高压相平衡体系，将二氧化碳真实地处理为超临界状态，其体积由适用于超临界流体的bwr状态方程求解。
