This paper firstly adopts A* heuristic optimization algorithm to study the partition evacuation in public places with people's position fixing through translating partition evacuation into allocation problem.
通过将分区疏散转化为分配问题(Allocation Problem),并采用启发式的A*优化算法,对人员位置固定的公共场所分区疏散进行研究。
The canopy structure characteristics, yield, and quality differences were comparatively investigated between the horizontal trellis system (HTS)and the delayed-open central leader system (DLS) of‘Hosui’ pear tree with WinSCANOPY2005a for hemispherical image analysis.
以‘丰水’梨棚架形与疏散分层形两种树形为对象,应用WinSCANOPY2005a冠层分析仪比较研究了两种树形的冠层结构特点、产量、品质差异及其相关性,结果表明:棚架形平均叶倾角,冠层开度,冠下直射、散射及总光合光量子通量密度显著或极显著高于疏散分层形,而叶面积系数极显著低于疏散分层形。
The evident vantage of the bands decentralized control system is made not only on enhancing output and decreasing cost but also in high efficiency energy saving.
针对上述问题产生原因进行了分析,提出了解决办法,采用多段分散式控制布置,在增产降耗、高效节能上具有明显的优势。
