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。

When EMS was applied, it was found that 2.0% EMS resulted the highest microkernel rate (15.6‰). Treating the materials with 2.0% EMS for 4 hours could lead to semi-lethal. Cytological observations found that chromosome aberration phenomena such as single microkernel, double microkernel, three microkernel, chromosome bridge, resort chromosome and syncytium were presented in the mutants.

EMS诱变途径中，浓度为2.0 %处理时间为4 h的组合获得最高的微核率（15.6‰），EMS浓度为2.0 %处理时间为4 h的组合使材料达到半致死；细胞学的观察看到了单微核、双微核、三微核、染色体桥、滞留染色体和合胞体等染色体畸变现象，再生苗中发现了1棵变异株。60Co辐射的诱变途径中，20Gy的剂量使不定芽半致死，再生苗中发现了1棵变异株。

This markedly greater degree of tolerance results in frequency distribution curves of deviations with much more gradual slops and a much wider bade than in the instances above.

这种显著较大的容忍度使变异的次数分布曲线比潜在结构有和缓许多的边坡与宽阔许多的基部。

Far infrared radiation is called "Light of Life", 93% Full radiation rat( Generally 83% is qualified), which can give new " Energy" to hydrone to make the variant shake frequency get right, improve activity and function of water, and also make water hydrone small. It's good for body cells to absorb in.

远红外线被称为&生命之光&，93％全辐射率(一般83％为合格)，能给水分子一个新的&能量&，使变异的振频恢复正常，提高水的活性和功能，并使水分子团变小，有利于人体细胞吸收。

Objective This study was designed to investigate the different status of provirus HIV DNA in non-progressor and progressor of HIV-1 infected persons.Methods HIV RNA, HIV DNA were detected with long-distance PCR,reverse-transcription PCR,Southern blot and molecular hybridization from plasma and peripheral blood mononuclear cells, using primers locating between long terminal repeats LTR(U5)-LTR and so on.

HIV是一种变异非常活跃的病毒，这种变异既有可能医疗增强病毒在宿主体内的适应性和生存，又有可能医疗使病毒复制受到阻碍，影响病毒在宿主体内的生存，为了更进一步掌握HIV变异规律，阐明HIV致病机理，我们用逆转录PCR、长片段PCR、Southern转印、分子杂交等对HIV感染无进展者和进展者HIV RNA、CD4细胞、HIV DNA及存在状态进行了研究。

That the transition from ape to man is to make the existence of phase variation, genetic and natural selection to be the basic factors play a role is one of the two-legged walking means perfect stage.

可以认为从猿到人的过渡阶段的存在是使变异、遗传及自然选择得以起作用的基本因素之一，是两足行走方式完善化的阶段。

Compared with the exchange and mutation operation in genetic algorithm ,crossover operation becomes helpless when adaptive value of most individules in demes have little difference.The algorithm falls into local solution and can't be solved by exchange. Although mutation can make it shake off local convergence and jump out of local solution, denteric mutation may destroy the produced module that is constructive to form the optimal solution.

相比遗传算法中的交换和变异操作，当种群的多数个体适应值相差不大时交叉操作就显得无能为力，算法陷入局部解而不能由交换解决，突然变异能够使之摆脱局部收敛而跃出局部解，但是后期的变异可能破坏已产生的对形成最优解有建设性作用的模块。

Results We observed associations between variant alleles of multiple CISH polymorphisms and increased susceptibility to each infectious disease in each of the study populations.

研究人员最终确认了5组不同的CISH基因变异，其中一种变异（标记为-292）会使该变异基因携带者易感传染病的风险增加18%。

copolymerization：共聚合(反应)

由於分子本身具有互变异构(Tautomerization)或共振(Resonance )现象及六环的立体阻碍因素,使的其不仅无法进 行单一聚合(Homopolymerization),也很难与其他单体进 行共聚合反应(Copolymerization),2(2'-氰化乙基)马来 醯□单体也具有类似结构,

positive feedback：正回馈

换言之,族群数量太少及基因变异减少交互影响,会走向灭绝旋涡(extinctionvortex),正回馈(positive feedback)循环使族群数量越漩越少,最终走向灭绝. 对繁殖潜力高的生物而言,并不会因低遗传变异性而毁灭,如多种杂草. 但对繁殖潜力低的生物而言,

focus：聚焦

另外在注塑盘基所造成密度的变异与各方向上不同厚度等问题,会使盘基的质量中心偏移物理的尺寸中心,造成在旋转时的"不平衡"(Unbalance)与"聚焦"(Focus)的问题,这常见于高速旋转下光盘所产生的噪音.

imprinting：压印

基因之所以会发生变异,与一种被称为"压印"(imprinting)的现象有关. 众所周知,胚胎从双亲那里接受了大部分基因的副本,但"压印"会造成只激活来自一方的基因,使来自另一方的基因仍处于休眠状态. 研究人员在6种基因中发现有4种的"压印"模式变异范围非常广泛,

polymorphic：多形的

同个体差异相关连的,有一点极使人困惑:我所指的即是被称为"变形的"(prot ean)或"多形的"(polymorphic)那些属,在这些属里物种表现了异常大的变异量. 关于许多这些类型究应列为物种还是变种,几乎没有两个博物学者的意见是一致的.

Statistically significant：统计显著
