  1. Using the data of these nhtidzs from 1992 to 2001, paying attention to those index reflecting the industrial level and ability, we establish an evaluating item system, and rank the 53 zones by three different methods in long and middle term, analysis some special phenomenon in this thesis. the three methods are : ahp ( analytic hierarchy process ), topsis ( technique for order preference by similarity to ideal solution ) and rsr ( rank sum ratio )

    本文利用全國53家高新區1992年至2001年間的各項經濟指標,側重選擇反映高新區產業化水平及能力的相關指標和經濟發展指標,利用分層分析法、 topsis法、秩和比法三種不同的方法,分長期、中期兩個時限,對全國高新區進行了排序,並對一些有代表性的現象進行了分析。
  2. The author first explains that large - scale measurement device is one of the most basic measuring methods of obtaining external trajectory data and flight status. lt is pointed out that the accurateness of the main - item axis system deviation correction ( including vertical, level and collimating axis deviation ) of large - scale measurement device error is of critical importance to the precison of measuring device ' s surveying angles. to improve its precison, the influence of axis system deviation on surveying angles must be corrected

    首先說明了在現代航天靶場中,大型測量設備是獲取外彈道數據和飛行狀態的最基本的測量手段之一,指出大型測量設備測量系統誤差的主項軸系偏差(包括垂直軸偏差、水平軸偏差和照準軸偏差)改正的精確與否直接關繫到測量設備的測角精度,因此要提高測量設備的測角精度,必須對軸系偏差對測量角的影響進行改正。
