智能图象编辑是近年来发展迅速面向工程图处理的新一代图象编辑技术，其关键在于结点处理。

Fertilizing date presented obvious effects on root growth and distribution. Fertilization after watering was more primitive to the root in up-soil layers than before watering. Fertilization of Ca-Mg was positive to the increase of root in 5-15cm soil layer, but negative to that in the surface layer. Both fertilization date and Ca-Mg fertilizer affected root vigor obviously.

施肥时期对根系也具有明显的影响，与灌水前施肥相比，灌水后施肥有利于促进根系在上层土壤中的生长和分布；钙镁肥的施用能增加5~15cm土层根重，但对表层根的生长不利，施肥时期和钙镁肥施用与否对根系活力的影响也较大。

Aiming at complicated computing and difficulty of being realized when extending single sensor PHD filtering to the multi-sensor case by means of probability generating function, a multi-sensor multi-target sequential particle-PHD tracking algorithm is proposed based on the thought of sequential filtering for a centralized fusion system. The algorithm chooses the importance density function with regard to every sensor, and updates sample particle of every sensor layer by layer.

当采用概率母函数将单传感器PHD滤波推广到多传感器情形时，针对计算繁琐，难于实现的问题，本文基于集中式融合系统的有序滤波思想，提出多传感器、多目标有序粒子PHD跟踪算法，该算法通过选取与各传感器相关的重要性密度函数，层层更新各传感器的采样粒子，达到多传感器多目标有序PHD跟踪。

By designing the mould to change the propellants model frame, selecting differentmaterials as propellant seal layer agents, studying the preparation technics, we havepreferably solved the PSS seal layer pressurize and combustion disciplinarian problem, andobtained the remarkable increasing burning surface effect.The practical increment ofΓvalue reachs 3.2 upwards conducting closed bomb firings, comparing with 19 holepropellants—the best progressivity burning in the present, whose practical increment ofΓvalue is 1.2, the PSS amplitude ofΓvalue exceeds 2.5 times.

通过药型结构和模具的设计、端面密封材料的选择和制备工艺的研究，较好地解决了PSS发射药的端面密封和燃烧规律控制问题，获得了显著的增面性燃烧效果，密闭爆发器实验中燃气生成猛度的实际增量达到了3.2以上，与目前增面性最好的19孔发射药实际增量的1.2左右相比，增幅超过了2.5倍。

Samples of the composites were taken for histological examination at day 7 and day 14 since OKCs were seeded. Results Multi-layer epithelia without hemidesmosome and basal membrane were observed in composites of PGA showing ill-defined cell layers. OKCs could adhere and proliferate onto collagen membrane forming multi-layer epithelia, with no mature hemidesmosome and basal membrane. That of Alloderm showed normal epithelial structures, with hemidesmosome, basal membrane and cell pseudopod in lamina propria.
