The preferences are analyzed, pipe ’ s parameters such as depth, thickness, pipe diameter, and mechanical property of material ; soil parameters such as soil types, internal friction angle, pipe - soil interaction ; fault ’ s parameters such as fault types, fault throw, fault drop, fault - pipe angle, mechanical property of material ; load types such as gravity force, linear displacement load, seismic load and seismic wave. some conclusions are drawn from the calculating results : when buried pipes cross fault, pipe ’ s embedded depth should be shallow, and big pipe diameter and thick wall should be selected. avoid the site where fault moves severe, and select suitable pipe - fault angle
在有限元三維模型建立中考慮的因素有:管道自身參數如管道埋置深度、管壁厚度、管徑、管道材料等;巖土材料參數如土體類型、巖土的內摩擦角、管土相互作用等;斷層考慮有斷層類型，斷層斷距，斷層錯動距離，斷層與管道的交角，斷層材料的考慮等;荷載分別考慮靜荷載，動荷載，其中動荷載包括線性位移加載、地震力加載和地震波加載等。 -
Hammer, air - lift gravity drop
氣提自落錘 -
The reactor can be shutdown during emergency by cutting off the power supply to the control rod driving mechanism which then causes the control rods to drop down to the reactor core by gravity quickly and thereby stopping the nuclear fission immediately
在需要緊急停堆時， ?須切斷控制棒驅動機械的電源，控制棒便會因地心吸力而快速下墜至反應堆堆芯，立即停止核裂變。 -
In order to know the relationship between gas - content and pipeline ' s pressure drop, the thesis deduces the pressure drop calculating equations based on uniform flow pattern and separating flow pattern. the equations show that pressure drop is made up of three parts, that is, friction resistance effect, gas acceleration effect and the gravity effect. and the research has shown that the gas has little effect on pressure drop. in the horizontal pipeline, the resistance effect must be overmatched the acceleration effect
為探討加入的氣體對管道壓力的影響，本文基於分相流和均相流兩種模型分別推導了三相流管道的壓降公式，表明無論是分相流模型，還是均勻流模型，管道內流體總的壓降是由三項組成的，即摩擦項、加速項和重力項，並得出了加氣對管壓變化不大的結論，所以認為在水平管道中，要獲得有效的減阻，則要使摩擦阻力分量的減小效應大於漿體加氣的加速效應。 -
The research results show that the counter - flow condensers have a better performance than that of other arrangements in single - circuit condensers, and that branch flow should be adopted in multi - rows condensers to decrease the pressure drop and increase the heat transfer capacity, and that the influence of gravity force can not be ignored, and that there must be an optimum refrigerant mass flow which can make the condenser perform best when the air velocity is constant while there must be an optimum air flow which can make the condenser perform best when the refrigerant mass flow is constant
研究結果表明，單迴路冷凝器中，逆流布置換熱效果最好，叉流其次，順流最差；多排管冷凝器應盡可能採用分流方式，以減小壓降，增強換熱；布置冷凝器流程時，重力的影響不可忽略；當風量不變時，必然存在一最佳製冷劑流量使冷凝器性能達到最佳；當製冷劑流量保持不變時，也相應存在一個最佳風量使冷凝器性能最佳。
