主要結論如下;隨著流量的增加，消力池收縮斷面弗勞德數減小，消力池的消能率減小。壩面平均流速增大，壩面的防護難度增加。In ovx rats, not only bone mineral density ( bmd ) of lumbar vertebrae in vivo and vitro, but also bmd of femora ( except for r3 region ) and proximal metaphysis ( r1 region ) in vitro decreased obviously ( p < 0. 01 ) ， whose bone loss rates of l5 and l6 were the highest and achieved 13 % ; the trabeculae of ovx rats were few ， fine, and discontinued and there were lacunae on the surface ; in ovx rats, both compressive strength of vertebral bodies and the mechanical properties of femora decreased ; the falling degree of the former was greater ; the maximal compressive power of lumbar vertebrae decreased with 33. 32 %
結果顯示：大鼠卵巢切除后，活體、離體腰椎以及股骨（除r3區） 、脛骨近端干骺端（ r1區）的離體骨密度顯著下降（ p < 0 . 01 ） ，離體l5和l6的骨丟失率最大，達13 % ；骨小梁減少、變細，連接中斷，骨小梁表面有吸收陷窩；腰椎壓縮強度和股骨力學性能均下降，前者更明顯，腰椎最大壓縮力下降率達33 . 32 % 。
