A new particle filtering algorithm was proposed, which introduced Swarm Intelligence niching technique into particle filtering in order to enhance particles diversity and search ability and convert above issues into a multi-modal optimization so that measure information is fully. As a result, particles can move towards the high likelihood areas which increase precision for system state estimation.

提出了一种新的粒子滤波算法，将群智能算法中的小生境技术引入粒子滤波中，增强粒子的多样性和寻优能力，同时将上述问题转化为多模寻优问题从而充分应用观测信息，使得采样后的粒子朝着高似然区域移动，从而有效地提高系统状态估计精度。

As some of the monomer emulsion added diffuses into the particles and another nucleates to form new particles, there are two phases also and the monomer droplet seldom exists even though at the initial stage.

单体的不断加入和聚合，使单体在两相中分配未达到平衡，本文引入动态分配系数△Z，提出了校正的热力学关系式，用于各相单体分配的计算，结果与实验值很好地符合。

Dr. Huang's research areas are numerical simulation and analysis in atmospheric optics, including laser beam propagation in the atmosphere, light scatting by non-spherical particles, and optical property of aerosol particles.

The oil can always be removed during the stiffing. Third, your muneca may be contaminated with particles either from worn and loose fibers on the muneca or from particles in the air that have landed on the guitar.

油可以在强化时去除。3，你的涂施包可能被破碎的布纤维污染了也或者是空气中的飘尘落到了乐器表面。

Fe2O3 acts as an activator more than a catalyst in the desulfurization reaction with lime. Fe2O3 acts as the "activation center" around which CaO particles are sulfurized. The new dispersal formation mode of product differs from the compact layer that used to be. And the pore structure of product layer on the surface of lime particles is optimized, which makes SO2 penetrate into core parts of lime more easily. As a result, the desulfurization reaction is developed deeper into the core parts of absorbent.

氧化铁所起的是改变石灰颗粒表层产物生成方式的活化作用，使反应生成物不会形成一个致密的外壳，而以氧化铁为活性中心进行硫化反应，形成了分散的硫酸钙产物堆积，改善了硫化过程中的表面孔隙结构，减少了石灰颗粒表面硫化产物层对反应气体向石灰颗粒内部扩散的阻力。
