Fractal is a subdiscipline of nonlinear area, researches on fractal characteristics of the deoxyribonucleic acid sequence may reveal some secret hidden in the DNA sequence during the process of biological evolution. Chaos Game Representation was proposed as a scale-independent representation for genomic sequences by Jeffrey in 1990. This technique, based on iteration function system, represents the word distribution statistics in DNA sequence as the fractal graphic. Therefore, we can get the distribution of sequence through analysis of fractal theory.

分形是非线性领域的一门分支学科，关于脱氧核糖核酸序列分形特征的研究，可以揭示生物在进化过程中隐藏在DNA序列中的某些秘密。1990年Jeffrey提出了基因组序列的与尺度无关的混沌游戏表示法，这是基于迭代函数系统的一种方法，它将DNA序列中一定长度字的分布规律表现为图形的分形特征，进而通过分形分析就可获取序列的分布规律，从而也成为DNA序列分析的一种统计方法。

The main purpose of the present paper is to obtain the relation between the abstract presentation of Euclidean objectivity and its component representation with respect to the general curvilinear coordinate systems with a relative rigid motion under a fixed frame of reference, so that the tensor representation of Euclidean objective quantity has its component form.

The system is played just somewhat like the game「Monopoly」rolling dice to determine the steps, and each step has different question, it features the combination of multi-representation and cooperation learning.Fraction plays an important role in learning, because it is a unit that full of representation in mathematics.

游戏的进行方式是模仿知名游戏大富翁，以随机的骰子点数决定目的位置，走到目的位置之后将进入不同的测验画面；本游戏式学习系统的特色是融合多重表徵与合作学习。

It is proved by experiments that real-valued vector representation is better than binary representation in dealing with the complicated problem.

实验证明实值向量表示方法在处理复杂问题时优于二进制表示方法。

Compared to state-of-the-art methods based on Kohonen's adaptive-subspace self-organizing map, our method avoids confusion of data in the manifold representation. Each neuron in the network approximately learns the mean vector and principal subspace of the data in its local region. The data representation is therefore more discernable.

与现有的基于Kohonen的自适应子空间自组织映射网络(Adaptive-subspace self-organizing map， ASSOM)方法相比较，本文方法有效地克服了流形表达中出现的数据混淆现象，网络中各神经元渐近学习各自区域内样本数据的平均向量和主元子空间，数据表达更加清晰可辨。
