使变异

In this algorithm, inertia weight is nonlinearly adjusted by using population diversity information. Velocity mutation factor and position interchange factor are both introduced and the global performance is clearly improved. The algorithm has been applied to optimization of parameters in SVM.

该算法利用种群多样性信息对惯性权重进行非线性的调整，并在算法的后期引入速度变异算子和交换算子，使算法摆脱后期易于陷入局部最优点的束缚，同时又保持前期搜索速度快的特性。

该算法利用种群多样性信息对惯性权重进行非线性的调整，并在算法的后期引入速度变异算子和位置交叉算子，使算法摆脱后期易于陷入局部最优点的束缚。

Based on genetic algorithm,a new hybrid coding method using the integer and floating number was presented. The enumerable method guarantees each individual in the population to satisfy the constrains, thus the punishment function was avoided. The two adjustable parameters made the evolution process jump out of the local best solution perfectly.The application of the fitness assignment based on Pareto ranking attained inferior solution set of the multi-objective and multiple options were provided to the decision-maker.

设计了一种新的整数和浮点数结合的编码方式；通过列举法使得每代个体满足约束条件，避免了罚函数的使用；可调整的双参数变异算子使进化过程能够较好地跳出局部最优解；应用基于Pareto排序的适应值分配方式得到目标函数的非劣解集，为决策者提供了多种选择方式。

About 46% of women have a version of the gene that contributes to high enzyme activity.

大约46%的妇女携带该基因的一种变异体，这种变异使该酶的活性大大增强。

The principal mass-independent cause for variation in the basal rate of eutherian mammals is that high rates of energy expenditure, when ecologically feasible, facilitate high reproductive outputs, whereas some habits and environments require low energy expenditures, which lead to low rates of reproduction.

除体重因素外，导致真兽类基础代谢率变异的主要原因是：当生态因素适合时，高水平的能量消耗可以促进动物的高繁殖输出，而动物的某些习性和生存环境则会要求低能量消耗，从而使繁殖率降低。

Liu Xin's works contain flavor of metropolitan fashion and however not reduction of reality but decrease of material trace. He goes beyond a popular expression of life sentiment. The beauty gradually varies towards as a metropolitan mirage that is fictitiousness, plane and patterning. The man is abstracted as merely an outer form floating like a dissociating shadow.

刘欣的作品带有都市时尚的气息，但并非还原现实，而是尽量消减物质的痕迹，审美上也超越了满足一般化的生活情趣的表述，使美逐渐变异，直至发展为虚拟的、平面化、图案化的都市蜃景，人被抽空了本质，剩下符号的躯壳魅影漂浮游离于纠缠不清的心灵困局。

Results The ozone could cause death to flyblow and some of the pupa and adult of housefly and make the pupa of housefly eclosion restrain and filial generation of housefly nervure variation.

结果O3对家蝇卵有致死作用；O3对蛹有一定杀伤作用，使羽化受到明显抑制，羽化时间相对延长；O3对成蝇有一定致死作用，存活的家蝇进行传代，子代F1、F2、F3均出现短翅和翅脉变异，但对子代性别无明显影响。

Specifically, there are three kinds:(1) constant variation method to track two-body problem the root number of variables to establish perturbed equation;(2) coordinate perturbation method in order to track objects in real position and the location of an intermediate orbit perturbation differential equation as a variable to establish;(3) transformation theory, through a series of canonical transformation to reduce the order of the equations of motion to make it a more simple form.

具体做法有三种：（1）常数变异法，以二体问题轨道根数为变量建立摄动方程；（2）坐标摄动法，以天体在实际轨道上的位置与某一中间轨道上的位置差作为变量建立摄动方程；（3）变换理论，通过一系列正则变换，降低运动方程的阶数，使其具有更简单的形式。

Multiple DWFMT features could be used to form a reference invariant feature through the linearity property of Fourier-Mellin Transform and hence reduce the variability of the input fingerprint images.

利用Fourier-Mellin变换的线性性质，使众多的DWFMT特征形成非变异的参考特征以减少输入指纹图像的变化。

Firstly, with changing the name from Ryukyu to Okinawa, the timely annexation by Japan in the end of the pre-modem era made "Ryukyuan Consciousness" lose her opportunity to develop into "Ryukyuan Nationalism". Secondly, the thorough Japanization policy carried out through Okinawa at the time restructured the culture and identity of the area.

其一，琉球在进入现代之前，「及时」地为日本所吞并并易名为冲绳，使「琉球意识」失去成长为琉球民族主义的机会；其二，「脱中入日」后的冲绳被彻底地实施面向日本的同化政策，导致其文化结构发生变化，认同也随之发生本质上的变异。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
