  1. According to finite element segmentation principle, by combining test with observation, the author has measured the air streamline and speed distribution of burning equipment in dally situation, which provides some guide for research of air field in hearth on cold and hot conditions. and the law is found of air speed distribution by measuring its speed and distribution of upper and lower deck on cold condition, thus it lays the foundation for analysis on hot condition. under four burning states, we measure the air speed in single, double - deck, and find out its corresponding distribution law

    5 .根據有限元分割原理布置測點,採用降溫方法,用k五江9106等儀器分別測出單雙爐排燃燒方式4種不同工況下,該燃燒設備爐膛內coz 、 02 、 co氣體濃度,並找到了隨爐膛高度方向及深度方向變化規律;從燃燒原理分析評價了2種燃燒方式爐膛內coz 、 02 、 co氣體濃度場分佈特點及相應燃料層內乾燥、干餾、氧化、還原、灰渣層厚度,肯定了雙層爐排燃燒方式爐膛中c02 、 02 、 co氣體濃度場分佈合理性,從燃燒理論找出了最佳濃度場分佈狀態及燃料層內各反應層厚度。
  2. With piv technology, the flow field was measured to judge the performance of pump sump. by analyzing the pictures of velocity, streamline, turbulent kinetic energy and vorticity, we found that the turbulence was bigger while the ratio of the runoff increased. and the vortices always appeared in the field where the runoff was small

    通過piv試驗,測量了封閉式水泵吸水室內部的流場,以研究該水泵吸水室的性能; ( 2 )通過分析流速圖、流線圖、湍動能圖和渦量圖,發現了流量比越大,湍動越大,漩渦總是出現在流量較小的一側。
  3. In the first part of paper, we introduce the appliance of doppler weather radar in meteorological work in the near future, and simply enumerate all kinds of adjoint methods to retrieve data of radar. in the second part of paper, we choice some methods that are usually used domestically and overseas, compare excellence and flaw of the methods by using data of simulate wind field, analyze synthetically the precision of simulate result, the length of retrieval time and the structure of data distributing, lastly decide to regard ameliorated quasi - 4d adjoint method as retrieval technology in the paper. in the third part of paper, we retrieve the data of single doppler weather radar in hefei, anhui province, then calculate 3d wind field, streamline field, divergence, vorticity, helicity, moisture flux, divergence of moisture flux and potential vorticity from the result of retrieval

    文中第一部分對近年來多普勒天氣雷達在氣象工作中的應用作了介紹,同時簡單的羅列了反演雷達資料的各種變分方法;接下來在第二部分選取了幾種國內外常用的反演方法,利用模擬的風場資料比較各種方法的優缺點,從模擬結果的精度、反演時間的長短、資料的分佈結構上綜合分析,最後決定將已做改進的準四維變分分析方法作為本文的反演工具;第三部分就是反演安徽合肥多普勒天氣雷達資料,然後由反演得出的風場計算了各個時間各個層次的三維風速、流場、散度、渦度、螺旋度、水汽通量、水汽通量散度和位渦。
