查询词典 cleavage crystal

For different materials,the macrostructure of damage sites are dissimilar.The microstructure of damage sites were indicated as follows:the damages of granite and marble after being particle impacted were made up of damage of cleavage surfaces and crystal faces and spread of cracks along phase interface and pore space,which is harmful to mechanical property;while the damages of concrete and mortar were made up of cracks of transition zone and aggregates and plastic flow of C-S-H,which may cause more hidden danger to perma nence than to mechanical properties.

对四种材料损伤形貌的微观分析表明：花岗岩、大理石受颗粒冲击后产生的损伤主要为拉应力导致的解理面、晶面的破坏以及裂纹沿相界面和孔隙的扩展，对其力学性能有较大的危害；混凝土和砂浆的损伤由过渡区开裂、骨料破裂和C-S-H的塑性滑移共同构成，对耐久性造成的隐患远大于对力学性能的影响。

Because there are incompletely cleavages in Jidong magnetite concentrate grain, and octahedron crack exists in magnetite crystal, oxidation develops along octahedron crack or cleavage seam, strip oxidation or reticulation texture is formed, and then magnetite is oxidized to hematite completely.

由于冀东磁铁矿自身的特点，氧首先吸附在颗粒表面的解理缝周围，并与解理缝周围的磁铁矿反应形成针状或片状赤铁矿；然后氧化过程沿磁铁矿的八面体或解理缝继续发展，形成条状或网状结构的赤铁矿，最终完全氧化。
