不均匀分布

The key points of DGA is to start evolution with initial population evenly distributed in searching space to avoid the leakiness of subspace, to accelerate the searching process by directed crossover and mutation, to improve holistic survival and adaptive ability by means of competition and parallel evolution in genetic system. However, the crossover and mutation act on different lays in space made the searching uniform.

其基本思路是以空间上均匀分布的初始点展开演化以避免子空间的遗漏，以有方向性的杂交和变异加速和调节搜索，同时杂交和变异作用在不同层面上使搜索在整体上均匀化，通过遗传系统里的并行竞争提高整个群体的生存适应力，从而达到整体优化的目的。

While Bi, Al substituted Dy-iron garnet films for magneto-optical recording with Rb-doping not only decreased the crystallized temperature, but also decreased the grains sizes.

用热分解法制备的Bi，Al替DyIG磁光薄膜虽然是纳米晶，但由于其晶界分布不均匀、晶粒较大且均匀性差，当用于磁光记录时，晶界将产生较大的噪音。

So in this paper, the improved models were proposed which regarded the leaf photosynthetic trait and the light penetrating into row cucumber crop canopy heterogeneously, it is composed by the model of photon transport in heterogeneous leaf canopy and the empiristic formula which described regression between leaf age and maximal photosynthesis rate and use efficiency of sunlight.

The results show that as for the as-cast castings, eutectic Si particles are characterized as fibrous or long acicular shape as well as in homogenous distribution, and the impact absorbed energy varies from 1.17 to 2.35J. After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.45-3.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.

结果表明：铸态下共晶Si粒子大多为纤维状或长针状，呈不均匀的网状分布，冲击吸收功在1.17~2.35J的范围内变化后；经T6热处理后，团簇状Al-Si共品相明显减少，共晶Si粒子呈现出粒状或短棒状，且细小均匀，Si粒子的长宽比和面积分数都有显著降低，冲击吸收功在1.45~3.80J的范围内变化，比铸态有明显提高。

After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.453.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.

The results showed that there were significant differences among parameters of texture feature of the different land utilization. In the desertification, the mean and variance were comparatively high. The gray level was asymmetry, the contrasts between neighboring pixels were significant; while in water and irrigable land, the mean, variance was a little bit low, the grey level was symmetry; the mean, variance and gray level in the forest and dry land was between the above (desertification and water and irrigable land).

不同土地利用类型之间纹理特征参数差异明显，荒漠化土地的均值、方差值较高，灰度分布不均匀，相邻像元反差明显，内部变化剧烈；水体和灌溉耕地的均值、方差值很低，灰度值均匀，内部变化小；林地和旱耕地信息介于上述两类土地之间。

It is found that the spatial distribution of atmospheric aerosol is ununiform in horizontal direction and stratified in vertical direction.

观测资料表明，在大气温度和湿度水平均匀、层结稳定的情况下，气溶胶粒子浓度水平分布不均匀，而且垂直方向上也并不随高度单调递减。

It is shown in this paper that distributions of electric fields in five measuring slots of Uster Evenness Tester,and the errors caused by uneven electric fields were analysed.

There are several reasons for this: injection technology (usually featured by 128-cavity moulds) makes it extremely difficult to maintain uniform temperatures, to ensure uniform distribution of plastic etc. So outgoing pieces are not all the same and, because bottling lines are ever-faster, any downtimes caused by cap quality problems can inflict economic damages on the producer that are much higher than the unit cost of the individual cap.

这是有：注射技术的若干（通常是由在128腔模具）的原因使得很难保持均匀的温度，以确保即将离任件，所以不是所有的一样的，塑料等均匀分布，因为瓶装生产线是不断更快，任何停工时间造成的帽子质量问题可以对生产造成的是比个人帽的单位成本高得多的经济损失。

Standard clean room processing was used to prepare the paddle sample. The experiment can be operated by using the electrostatic deflection on the "paddle"cantilever beam and then measure the deposited thin metal film materials on top of it. The optical interference technique was used to measure the deflection of beam with the force.

此微桨型试件是藉由标准的黄光制作流程所完成，悬臂梁设计成梯形主要是为了提供均匀平面应力，以避免传统平行梁应力分布不均匀的缺点，实验时沉积金属薄膜材料於微桨型试件上后，再使用静电力驱动微桨型结构使其产生偏移量，并且搭配光学干涉仪器，用於量测试件受到外力作用下之平面偏移的数据。
