文摘:針對實際工程中的發電引水隧洞運行的各種工況進行了水工模型試驗研究,指明要獲得良好的水流流態,過水建築物各部位結構輪廓的造型應適應水流流線的收縮、流速及壓強的變化;為使引水隧洞在各級引水流量下能安全可靠地運行,需慎重確定洞內消能工的體形和尺寸。In the summer stratified water column, the deeper the maximum depth of food distribution is, the stronger the dvm is performed ; the increase of the gradient of temperature in the thermocline layer can decrease the magnitude of the dvm and form the thermal barricade to the copepod ; the effects of the predation pressure on dvm is complex. on the one hand, the variations in the distribution depth of the predation pressure vs. the thermocline layer or the depth of the maximum food can modify the dvm patterns of the copepod. on the other hand, different predation pressure induces different dvm patterns
在夏季分層水體中,食物的最大分佈深度越大,動物向下遷移的幅度也越大;溫躍層的溫度梯度增大可以減小動物遷移的幅度,成為橈足類垂直遷移的溫度屏障;捕食壓力對垂直遷移的影響較復雜,一方面,捕食壓力的分佈深度與溫躍層或食物峰值的相對位置的變化能夠改變橈足類垂直遷移的模式,另一方面,捕食壓力強度不同,橈足類垂直遷移的幅度也不同,捕食壓力越大,遷移的幅度越大,當捕食壓力增加到一定程度,橈足類停止向上的遷移,大部分時間呆在水體深層,可能進入捕食壓力引起的「滯育」狀態。On the basis of the study of the theory and appraise method on land use in the small towns from home and abroad, this paper at first conducts a deep study on the development and role of the small towns, indicating that its development has sawn an uneven development phrase and becomes a carrier of the enterprises, a pool of surplus laborers, a hub of material exchanges between the rural and urban areas, a base of spiritual civilization, an important way to achieve urbanization. second, it conducts a study on the situation and features and the problems the land use, indicating that the efficiency of the land use is low, which has a direct influence on the development of agriculture and the role of the small towns. and the study of the demand of the land indicates the shortage of land is serious, and the small town must rationally use the land and increases its intensive role and the economical efficiency to meet the demand

( 6 )建壩工程荷載條件下河谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出:建壩后河谷的巖體應力量值明顯增高,同時左岸的張應力區的范圍及量值明顯減小,主應力的方向依然與模型的底邊界垂直;大壩建成后逐漸蓄水階段以及同時考慮本區最強地震力的作用等各種不同的工況條件時,滑坡體及壩體總體上仍處于穩定狀態;水位驟降時,在未考慮其他外力作用的情況時,滑體的安全系數將顯著降低。若考慮水位驟降及本區最大地震力的共同作用,壩體將在滑坡體下滑推力的作用下產生破壞;建壩后水平推力對右岸古滑坡體穩定性的影響分析可以看出,在最危險的工況條件下,壩體及滑坡體也將處于臨界狀態;在長期滲透變形的作用下,由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。Sonar is a term that refers both to the application of underwater sound to the detection and location of objects in the sea and to the apparatus used in such application
