FRACTEID, as a portmanteau word, is used to describe a linguistic blend of "fractal" in its definition of fragmented geometric shapes that can be split into parts, and the Greek word Eidos (used for example in kaleidoscope) which refers to Plato's Ideal Forms and evokes the term "Eidetic memory," defined as the ability to recall images, sounds, or objects in memory with extreme accuracy and in abundant volume.

分形"FRACTEID"作为一个混成词，通常被用作形容不规则碎片在语言学上的混合，定义为可以被分成几个块或成碎片的几何形状，柏拉图理念形式所提及的古希腊词语理念，唤起"高级记忆"这个词语，定义为一种唤起记忆中极端准确的意象和物体，最顶峰值的声音。

Based on the model of DLA, this paper simulates the process of aggregation's growth for random walk particles from local area on two-dimension Euclidean plane. The aggregation is confined to Euclidean circular plane for large enough particle walking area and far enough partial source distance. The centre of the Euclidean circular plane is on the line between the particle source's symmetric centre and the seed particle, and is more closer to the particle source than the seed particle. Though the rate of aggregation growth is different in different directions, the whole aggregation shows fractal structure.

以DLA模型为基础，模拟研究了在二维欧几里德平面上由局部区域内产生随机运动粒子的聚集生长过程，发现对于足够大的粒子运动区域和足够远的粒子源距离，凝聚集团大体上被限制在欧氏圆形面内，圆心在粒子源对称中心和种粒子的连线上，且比种粒子更加接近粒子源；凝聚集团朝各个方向的平均生长速率虽然不同，但整体仍呈分形结构。

We use a hybrid distance measure by the combination of the symmetry distance and the Euclidean distance.

在本论文中我们提出改进的方法，藉由使用欧几里德距离与对称性距离混合的方式作为分群基准来解决上述的问题。

The results of determination show that all systems of these three groups are simple eutectic systems.

测定结果表明，这几组同分异构体体系均为简单低共熔系统。

The comparison of the numerical solution with exact ones among these four schemes is carried out.

然后对几种差分格式作了较详细的比较，尤其注意了对相对误差的比较。

Sometimes not a success, it is necessary to try to do several hours after the extended partition.

有时不是一次就成功，要多做几次尝试分后面的扩展分区。

Oxygen sensor performance testing include estimating failure,orientation and compatibility choice.

氧电池性能检测分氧电池失效的判断、定标及兼容氧电池的选择等几个方面来阐述。

In chapter 3, we give a unifying proof for some known difference sets by using Gauss sums, and we construct a new family of divisible difference sets.

在第三章中，我们用Gauss和给出了几个已知差集的统一的代数证明，它们原有的证明要么是用组合设计的方法，要么是用很技巧性的计数方法得到的。同时我们构造了一族新的可分差集。

The decomposition of a set into a family of mutually exclusive sets.

划分，分类：把一个集合分拆成几个互相排斥的集合族

By means of the deconvolution of the MWD curves by multiple Flory functions, we found that the reason was that introducing MgF_2 into the MgCl_2 support did not change the number of active center types existed in the catalysts.

掺杂MgF_2对聚乙烯的分子量分布的影响较小，对聚乙烯的GPC曲线进行Flory最可几分布函数的分峰拟合结果表明，掺杂MgF_2对催化剂活性中心种类数没有影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
