This paper proposes an Improved Particle Swarm Optimization algorithm.IPSO adopts a new mutation operator and a new method that congregates some neighboring individuals to form multiple sub-populations in order to lead particles to explore new search space.Additionally,this algorithm incorporates a mechanism with a simple and easy penalty function to handle constraint.Thus,this algorithm has strong global exploratory capability and efficiency while being applied to solve nonlinear constrained optimization problems.

提出了一种改进的粒子群算法（Improved Particle Swarm Optimization，IPSO），使用了一种新型的变异策略，并在搜索过程中将部分邻近的个体聚集成核，从而形成多子群引导粒子探测新的搜索区域，采用了简单易行的罚函数约束处理机制，使算法在求解较难的非线性约束优化问题时具有很强的全局搜索能力与效率。

在苯胺的化学氧化种子聚合体系中，以乳化剂预处理和与丙烯酸共聚改性的聚苯乙烯粒子为种子，制备具有一定分散稳定性的聚苯乙烯／聚苯胺核－壳型复合高分子粒子乳液。

Accordingly, many have suggested that the particles that make up dark matter interact with one another like molecules in a gas, generating a pressure that counterbalances the force of gravity.

因此许多天文学家认为，应该是组成暗物质的粒子与其他的粒子发生交互作用，产生的压力抵消重力所致。

Meanwhile, we discuss the deinking mechanism:solvent treatment dislodges most ink particles, then enzyme removes part of unconnected ink particles from the fibers so as to improve deinking effect of mixed office waste paper.

同时 我们对其脱墨机理进行初步研究，可以认为其作用机理为：先用溶剂预处理，将大部分油墨粒子从纤维上分离下来，然后再辅以酶的作用，将部分未与纤维分离的油墨粒子从纤维上剥离下来，从而大大地提高了混合办公废纸的脱墨效果。

The magnetic carboxymethylated chitosan-Fe3O4 nanocomposites were synthesized by one-step enwrapping method in which the magnetic Fe3O4 nanoparticles prepared via a modified co-precipitation method were enwrapped directly by carboxymethylated chitosan.

首先采用改进的共沉淀法制备四氧化三铁磁性纳米粒子，然后通过一步包埋法，将磁性纳米粒子用天然多糖物质－羧甲基壳聚糖直接进行包覆，制备出羧甲基壳聚糖磁性纳米复合物。

Small particles (typically 0.01-1 micron) move randomly in the suspension, collide with each other and form flocculates, reducing their

微小的粒子（粒径0.01-1微米）在悬浮液中自由移动，相互碰撞形成絮凝，降低总能量。粒子越小，絮凝作用越强。

Detects high-energy particles passing through a supersaturated vapor; each particle ionizes molecules along its path and small droplets condense on them to produce a visible track.

观察高能粒子穿过饱和蒸汽；每个粒子沿着自己的路径电离分子浓缩在其上的小滴能产生一个明显的轨迹。

Each particle's volume melds seamlessly with those of its neighbors to create an effect that can look like the real thing.

每个粒子的体积与临近的粒子相互连接并融合，通过这样的方式来创建一个真实性很强的效果。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
