  1. 3 based on the shape of conic plug, the profile modeling - annulus equipment which can make plug in a line is designed. this equipment can not only solve the plug lining - up problem in mechanizing way when plug seedlings are transplanted, but also can raise the working speed of no - tillage transplanter, and reduce the working intensity of operator

    3利用圓臺形缽體的外形特點，採用仿形導向輪式排隊裝置，解決了栽植過程的缽苗機械化排隊問題，提高了免耕栽植機的作業速度，減輕了操作人員的勞動強度。
  2. The goal of this paper is to study fully developed turbulent pipe flow. with the aid of the tripping annulus at the inlet, based on the experimental investigation and numerical simulation, detailed researches on a few basic rules in pipe flow have been performed, such as mean velocity profile, relative intensity of turbulence, the log - law, von karman ' s constant and reattachment length, thus filling some gaps in the research work of predecessors and obtaining a far - reaching understanding

    本文的目的就是利用入口擋環進一步探索充分發展的圓管湍流，通過實驗和數值模擬對圓管湍流的若干基本規律，如平均速度分佈、相對湍流強度、對數定律、馮?卡門常數和再附著長度等進行詳細的研究，以填補前人研究中的一些空白，並獲得更深入的了解。
