Design, setting, and patients the survival of patients with acute heart failure in need of intravenous inotropic support ( survive ) study was a randomized, double - blind trial comparing the efficacy and safety of intravenous levosimendan or dobutamine in 1327 patients hospitalized with acute decompensated heart failure who required inotropic support
設計，設定和病人：將患有急性心衰並需要靜脈收縮藥物支持的病人隨機分組，雙盲實驗條件下比較1327名患有急性失代償性心衰並需要收縮藥物支持的病人在靜脈注射左西孟旦或多巴酚丁胺后的效力和安全性。A reasonable position of driving nozzle helps to achieve the maximum material flow that also depends on other parameters such as backpressure, properties of conveyed material and driving gas. it is observed that, an increase of convergent section angle is harmful to the pneumatic conveying system, and also influences on the mass flow rate of conveyed material, the distribution of static pressures in injector and the pressure drops of conveying pipe. in addition, within a reasonable scope of air mass rate, increasing the driving jet velocity is more advantageous than enlarging the dimension of driving nozzle
試驗研究發現，氣體噴嘴位置對氣固噴射器的輸送能力影響最大，氣體噴嘴存在某一最佳位置，而這一最佳位置與背壓、輸送物料特性和輸送風特性相關聯；氣固噴射器的收縮角對其輸送能力、內部靜壓分佈和輸送管阻力特性均有適量影響，收縮角增大對整個輸送系統均不利；在適當的輸送風范圍內，提高氣體噴嘴出口速度比擴大氣體噴嘴尺寸更為有利，但氣體噴嘴出口速度過高會增加氣固噴射器和輸送管內的能量損耗，給輸送帶來不利的影響；系統背壓與氣固噴射器的氣體噴嘴出口速度的選取有關。It has a long history using a throttle device to measure the flow volume of fluid in pipe the method has formed normalization at home and abroad the principle is to make the flow bunch form the particial shrink at the place where the throttle part is located so as to produce a static pressure difference then measure and calculate the flow volume at the moment when the fluid is flowing through the throttle device by the static pressure measured this method is based on the law of conservation of energy and the equation of flow continuity
用節流裝置測量管道中流體流量已歷史悠久，在國內、國際上都已標準化，其原理是使流束在節流件處形成局部收縮，產生靜壓力差，通過測量靜壓力差來衡量流體流過節流裝置時的流量大小，這種測量方法是以能量守恆定律和流動連續性方程為基礎的。
