No matter with or without flange, the longitudinal strain in limbs roughly coincides with bernoulli ' s principle. 5 based on strain distribution status found in experiments, the internal force evaluation approaches are suggested. then, the structural behaviors are investigated in detail, and the concepts of pl and leffr are introduced
從墻肢應變分佈研究入手，建立了截面內力計算模型，深入研究了短肢墻結構內力大小及其分佈規律，建立了土墻肢及主墻肢荷載效應負載率等基本概念。 -
Through application investigation of dosing subsystem and utilizing principle of fluid mechanics ( bernoulli equation ), quantitative dosing device was produced to measure chemical dosage, so as to settle the problem that metering pumps and electromagnetic flow meters widely used in water plants now have a very high requirement in technique and a very high cos t in maintenance. this device is easy to control, simple in maintenance and low in cost ; functionally it can substitute for metering pumps and electromagnetic flow meters used in system
通過對投加子系統的應用研究，針對目前在水廠普遍使用的投加計量泵、電磁流量計技術要求和維護維修成本高等問題，運用流體力學（伯努利方程）的原理製作定量投液裝置對藥液加量進行投加計量；該裝置易於控制，維護維修簡單、成本低廉，功能上能取代系統中使用的計量泵和電磁流量計。 -
