摘要點校本《安順府志》以1986年電光掃描謄寫本為藍本，以咸豐、光緒兩個版本和歷代文獻、地方志書、大型工具書為校改的依據，多次核對原著，避免了錯字、漏字、脫句、落段等現象。In this paper ， an optimal search strategy by dividing the whole surveillance area into regions is presented so that the optimal search can be adaptively implemented in phased array radar. firstly ， the inherent relationship among average discovering time ， radar resources consumption ， search frame period and target distribution density is studied. secondly ， parameters for the region search are optimized to achieve the optimal search performance inside regions. then ， the optimal search frame period for each region is derived to minimize the average discovering time of targets ， where the constraint of radar time resource and the importance of each region are taken into account. finally ， the adaptability of this search strategy is discussed. only if the optimal parameters for each region are utilized and the beams are scheduled according to the optimal frame period under the radar time constraint ， the optimal distribution and the optimal scanning sequence of beams can be implemented adaptively. thus ， optimal search is adaptively implemented in the whole surveillance area
本文提出一種分區搜索演算法，實現了相控陣雷達的自適應最優搜索.首先，研究了各區域平均發現一個目標消耗的雷達資源和目標被發現的平均時間同搜索幀周期以及目標強度的關系；然後，研究了在各區域採用兩步搜索演算法的最優參數設計，實現了局部區域的最優搜索；其次，在雷達時間資源有限和區域重要性加權的約束條件下，導出了使目標被發現的平均時間最小的區域最優幀周期；最後，討論了分區搜索演算法的自適應性.只要採用各區域的最優參數，按最優幀周期調度雷達波束，就可以自適應地實現使目標被發現的平均時間最短的波束的最優分佈和掃描順序，即自適應最優搜索Because compiler scan program with static order of program, not dynamic order. while using compiler, compile source program only one time, run more times
因為編譯是按程序的靜態順序線形掃描程序的，而非動態順序重復翻譯，使用編譯程序時，只需對源程序編譯一遍，以後每次只運行目標程序。
