A new approach to eliminate the ranges dependence based on angular frequency shifting in space domain was presented, in which, the nonhomogeneity of clutter is removed and the blind area of target detection is reduced due to the fact that the clutter of all the compensated range cells in every channel is moved to the place of the clutter of the desired cell by the different angular frequency shifts being added into spatial data along all Doppler channels for every compensating range cell.
第七章针对非正侧视相控阵机载雷达,由于杂波在距离上呈现出严重的非均匀性,尤其是在近程这种依赖距离的杂波谱呈现的非均匀现象更为严重,使得用于计算自适应权的协方差矩阵不可能直接由距离单元数据统计平均来估计得到,否则STAP处理及其降维技术难以获得理想的杂波抑制性能和目标检测性能,甚至恶化。

A new particle swarm optimization, PSO with bounded mutation operator, was developed. In contrast to the original PSO, in this algorithm, PSO with bounded mutation operator would make the particles redistributed cquably close to boundary when place of particle exceeds feasible region during iteration.
提出了一种新的粒子群优化算法——带边界变异的PSO,其原理是:在迭代的过程中,当粒子的位置超出可行域时,带边界变异的PSO让粒子的位置重新均匀分布在边界附近;当粒子的速度超出可行域时,则使其均匀分布到整个可行区间,而不是像原始PS0那样在这2种情况下都只是简单地取边界值。

In the different zoning of xenoliths, molybdenum and tungsten contents is lower and homogeneous,and be lower than the world\'s average abundance; tungsten compared to molybdenum,the content more homogeneous in xenoliths, compared to mantle\'s average abundance more less. This explains the geochemistry incompatible character homophyly and diversity of molybdenum and tungsten determined their trend enrichment in crust in the course of the mantle evolution and magmatism, among molybdenum more trend enrichment in lower crust but tungsten in middle-upper crust.
包体不同带中,钼、钨的含量较低且较为均一,并低于世界均匀丰度;钨和钼相比,其在包体中的含量更为均一,相对于地幔均匀丰度更小,说明钨、钼的地球化学不相容性的类似性和差异性决定了它们在地幔演化和岩浆过程中倾向富集于地壳中,其中钼更倾向富集于下地壳,钨则更倾向富集于中上地壳。

The key points of DGA is to start evolution with initial population evenly distributed in searching space to avoid the leakiness of subspace, to accelerate the searching process by directed crossover and mutation, to improve holistic survival and adaptive ability by means of competition and parallel evolution in genetic system. However, the crossover and mutation act on different lays in space made the searching uniform.
其基本思路是以空间上均匀分布的初始点展开演化以避免子空间的遗漏,以有方向性的杂交和变异加速和调节搜索,同时杂交和变异作用在不同层面上使搜索在整体上均匀化,通过遗传系统里的并行竞争提高整个群体的生存适应力,从而达到整体优化的目的。

The results showed that the aluminum plates had a much better effect than zinc plates in identifying crystalline free silica. The all open-faced samples had good uniformity in the filter no matter how many middles were used, but not so good for the closed-faced sampling. The calibration curve had a good correlation coefficient (r=0.995). Due to different industrial operating patterns, the distribution of crystalline free silica concentration varied by the industrial environment. The dust consisted of 10- 30% of crystalline free silica in all samples obtained from the foundry environments. The crystalline free silica was accounted for less than 10% in the respirable dusts.
结果显示,因为铝板对於结晶型游离二氧化矽具有较良好的补正系数,因此做为本研究的基底标准吸收校正的校正元素;SKC铝制旋风分离器搭配开匣式滤纸匣於一阶中环、二阶中环、三阶中环均有良好之均匀度,反之,搭配闭匣式滤纸匣其均匀度均不佳;分析检量线具有良好线性关系(r=0.995),因作业型态不同,作业环境会有不同的浓度分布,综观作业环境中可呼吸性结晶型游离二氧化矽之含量均小於10%以下,总粉尘结晶型游离二氧化矽之含量约为10 – 30%之中。
