1·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。

2·The factors related with metamorphic reservoir space are crystallization, structure, physical weathering, and chemical eluviation.

变质岩储集空间形成主要有：结晶成因、构造成因、物理风化成因、化学淋溶成因。

3·The rapid crustal uplift in the Pleistocene and physical weathering and erosion, especially the erosional process of the flood in the mountains, are the direct causes for the formation of the gorges.

更新世阶段地壳迅速的抬升、外力的物理风化作用，特别是晚更新世间歇性山区洪水的冲蚀，是形成嶂谷的直接原因。

4·Weathering of loess soil is physical and biochemical processes mainly controlled by the root systems of plant community.

黄土的风化主要为植物群落根系的物理作用及其所引起的生物化学作用。

5·As a kind of natural building material, rock usually is influenced by weathering. Therefore, it is necessary to research the influence of weathering on rock physical and mechanical characteristics.

岩石作为天然的建筑材料，通常承受着自然界的风化作用，因此，研究风化对岩石物理力学特性的影响是十分必要的。

6·Weathering means the physical and chemical change of minerals and rock under new physical and chemical condition. It is a change in original place affected by atmosphere and bioss.

风化(weathering)作用：是指矿物、岩石在地表新的物理、化学条件下所产生的一切物理状态和化学成分的变化，是在大气及生物影响下岩石在原地发生的破坏作用。
