At the early iteratives, the mutation rate is bigger and the aim is to make particles to explore smaller and isolate region and to avoid the algorithm trapping to the local optimum. While the algorithm runs, the mutation rate will be decreased to reduce the disturbing to the particles. IPSO adopts a new method that congregates some neighboring individuals to form multiple sub-populations in order to lead particles to explore new search space. Additionally, our algorithm incorporates a mechanism with a simple and easy penalty function based on the largest distance between the particle and the boundary of the feasible region to handle constraint.

IPSO采用了一种新型的变异策略，变异概率随着算法的运行是动态变化的：在算法运行初期，变异概率大，其目的是使算法不但能够探测到目标空间中的孤立区域，而且避免搜索陷入局部极值；在算法运行后期，变异概率逐渐变小，以减少对粒子的扰动；算法通过将部分具有邻近距离的粒子聚集成核形成多子群引导种群中粒子的飞行；采用一个简单的基于粒子与可行域边界最远距离的罚函数处理约束的机制，使得算法高效实现。

Beginning in the new century, in the face of the wave of global economic integration, the company also in their own development plans clearly: The development of high-tech achievements into the market, relying on high technology, gathered first-class talents and create first-class products, providing first-class service Yutian Zhengtai feed mill will be developed into the most well-known agricultural modernization level

在新世纪的开端，面对全球经济一体化的浪潮，公司又在自己发展规划中明确提出：以高科技成果的开发进入市场，依赖高科技，聚集一流人才，创造一流产品，提供一流服务，将玉田正泰饲料厂发展成为国内最知名的农业现代化企

Hepatic sinusoid capillarization plays an important role in occurrence of portal hypertension. The fenestra of endothelial cells in hepatic sinusoid reduces and the diameter of fenestra decreases. The formation of basement membrane impaires the substance exchange between blood and hepatic cells,which results in oxygen deficiency, metabolic product accumulation and cell necrosis.

肝窦毛细血管化在硫代乙酰胺诱导的肝硬化门脉高压发生中起重要作用，肝窦内皮细胞窗孔减少并减小，内皮细胞下基底膜形成使肝细胞与外界物质交换减少，导致细胞缺氧、代谢产物聚集，肝细胞坏死，最终导致门脉高压的发生。

The testing results showed that the optimal reduction conditions are 1320℃ for 120 min and the proportional mass fractions of activated carbon powder and the additive A are 3% and 5%, respectively. The additive A accelerates the aggregation of metallic grains so as to make the enriched metallic grains easier for magnetic separation. The mass fraction of maximum nickel in ferronickel alloy and nickel recovery in the laterite-nickel ore are 8.31% and 95.44%, respectively. Metallic nickel is thus enriched.

研究结果表明，最佳反应条件：还原温度为1320℃，还原时间为120min，还原剂与添加剂的质量分数分别为3%及5%；添加剂可促进金属晶粒的聚集，富集的金属晶粒更易于磁选分离；还原产品镍铁合金中镍的质量分数可达8.31%，矿石中镍的回收率可达95.44%，金属镍得到了富集。

异黄酮可协同腺苷的作用，降低血管阻力，增加血流量；同时也能有效抗血小板聚集，抑制其细胞因子释放，促进内在纤溶酶活性，亦降低血浆儿茶酚胺浓度作用，进一步改善耳蜗微循环。

The ability of magnetic particles to concentrate depends on both the blood flow rate and the intensity of magnetic field.

磁颗粒的聚集的能力取决于血流速度和磁场的强度。

In bank based financial system, information is mainly contained by banks. So enterprise faced much more external finance costs than market based financial system.

在银行主导金融系统中，由于信息主要聚集在银行体系中，而令企业寻求其他外部融资资源的成本相对高昂。
