Then, by the comprehensive analysis of essential conditions for stone forest development, and the quantitative study on the evolution phases of bajiang karst catchment and the spacial coupling analysis of its hydro - geomorphological system, the paper studies the relationship between the evolution of bajiang karst drainage area and the development of stone forest, and, combined with the evolution history of the catchment, puts forward a model concerning the relationship between the evolution of bajiang karst catchment and stone forest development, in the mechanism of " tri - level erosion ", if a < s < c, the visible and actual height of stone pillars will keep on increasing, meanwhile, soil layer among stone pillars will become thicker and thicker, so the the height of stone pillars " root will become higher and higher, too
在「三重剝蝕」機制中,若a s c ,石
柱的可見高度和實際高度會不斷增高,同時,石
柱的根部的土層會增厚,其土下部分的高度也會不斷增大。若a c s ,說明石
柱的實際高度在增加的同時,其可見高度也在增加,但土層會變得越來越薄,最終當底土被完全剝蝕掉后,氣下溶蝕和土下溶蝕的差異消失,此時a接近於c ,石
柱的實際高度將停止拔高或極緩慢增長,並在各種物理、化學風化的作用下而變得日益
矮小。若s a c ,石
柱的可見高度將趨于變
矮,但驅動石林發育的土層厚度將會增大。
However, there is obvious connection with hormone imbalance as in menopausal and protein excess, both of which affect calcium utilization in the body
人到中老年,個子變
矮,腰背彎弓,就與脊

Previous research however, was mainly focuse on the seismic properties of low - rise shear wall, the research of seismic properties on mid - rise shear wall with frame columns are very far from satisfaction
然而,已有研究大多集中在低
矮剪力墻的抗震性能上,對于高度較大的中高帶邊框
柱剪力墻抗震性能的研究卻相對較少。
Experiment and theories analysis express low shear walls the general occurrence shear to slice the breakage, before shearwalls " concrete crack, the wall plate concrete under takes the big part shear stress, exsist inclined pull lord should dint ; after wall concrete crack, wall plate the reinforcing bar undertakes the big part shear stress, so changes to suffer the mechanism originally, hence formation the inclined direction suffers to press the piece of with suffer to pull the reinforcing bar pull, press the resistance
試驗及理論分析表明低
矮剪力墻一般發生剪切破壞,在墻體混凝土開裂前,墻板混凝土承擔大部分剪力,存在著斜拉主應力;在墻體混凝土開裂后,墻板中鋼筋承擔大部分剪力,從而改變了原來的受力機理,於是形成斜向受壓構件(裂縫間混凝土斜壓
柱體)和鋼筋的拉、壓抗力。
Spinal or vertebral fractures also have serious consequences, including loss of height, severe back pain, and deformity
脊椎或脊
柱骨折也常導致嚴重的後果,包括身高變
矮嚴重背痛及脊椎變形。
The gray pillar guild, expert architects, felt they had to reclaim the inheritance of their dwarven ancestors ' technology
