Examples
- The main factors influenced fractures development are the tectogenesis , the physical weathering and the chemical dissolution
影响裂缝发育的主要因素是构造、物理风化和化学淋溶作用。 - As a small - scale illustration of the artificial modification of physical weather processes , take the frost prevention in an orchard
我们可举果园中防霜作为说明对天气的物理过程进行小尺度人工影响的例子。 - The mainly reservoirs in the middle of damintun depression of liaohe basin are the regional metamorphic rocks and the migmatites , which are more fractured and rigid by the cataclastics . the space of metamorphite is the mainly fractures , which are produced by the tectogenesis and the physical weathering
2 、辽河大民屯中部地区主要储集岩是太古界的区域变质岩和混合岩类，尤以裂缝发育和经过碎裂化的刚性变质岩类的储集性能最佳。 - The second stage is stage of the matter transfers the activated matter , that is to say , minerals build up their surface area after passing though physical weathering , maifan stone form a lot of clay mineral , oxide , oxhydroxide and collide mineral after passing though chemical weathering . it makes nutrition elements transform from crystal state to adsorption state and it expands the activation of mineral , in the latter stage , it makes maifan stone have many special physicochemical adjusting character , for example , ph and foi bi - directional absorptive and ion exchange character , so these characters expand maifan stone ' s uses
第二阶段为物质转变的活性阶段，即通过物理风化增大表面积、通过化学风化形成大量粘土矿物、氧化物和氢氧化物及胶体矿物，使营养元素由结晶态转变为吸附态，从而大大增加了其活性。在后一过程中麦饭石还形成了许多特殊的物理化学性质，如ph值和f _ ( o2 )的双向调节性，吸附性和离子交换性等，从而扩大了其用途。
