变量

By decomposing the real growth rate into three elements : structural shocks , structural transformation and labor productivity growth , this paper hurdle this intrinsic weakness of agone research .

通过构造变量，本文将各地区的实际增长率分解为结构冲击，结构转换与生产率增长三部分，从而克服了以往研究之不足。

Dr. Agricola's group reports in the October issue of Heart that all of the ariables correlated significantly with the effectie regurgitant orifice.

Agricola小组在10月份杂志《heart》指出，所有测量变量都与有效二尖瓣返流口大小成比例。

The process consists of:First of all, basing on the statistical data through a market survey, this paper uses the methods of principal component analysis and K-means clustering to analyze the AIO lifestyle variables and divides college notebook market into social-oriented consumers market, economy - oriented market, self-oriented consumer market and fashion-oriented consumer market from the perspective of lifestyle;In the following, make analysis of the differences on the assessment of the product attributes in different segment markets to support the marketing strategies for Lenovo;Finally, in accordance with the college segment of the consumer lifestyle preferences and product characteristics, choose the differentiation strategy and gives recommendations on marketing mix strategy for Lenovo.

主要工作如下：首先，本文通过市场调查获取数据，以AIO生活方式变量作为集群划分的基础，通过主成份分析法和K-means聚类，将高校笔记本市场从生活方式的角度细分为社交导向型消费者市场、经济导向型消费者市场、自我导向型消费者市场和时尚导向型消费者市场；接着，本文研究了按生活方式划分的各高校消费者集群在产品属性评估上的差异，从而得出各细分市场的特征，为营销战略的制定提供支持；最后，根据各高校细分市场消费者的生活方式上的特点和产品偏好，实施差异化战略，在各细分市场给联想笔记本提出市场营销组合策略方面的建议

An algebraic expression is a combinaation of constants and variables.

3\一个代数表达式是由常量和变量结合而成的。

An algebraic expression consisting of one or more summed terms, each term consisting of a constant multiplier and one or more variables raised to integral powers.

多项式包含一个或更多总项的代数表达法，每一项都含有一个常乘数和一个或更多整幂的变量。

The second part is an introduction to higher- dimensional algebraic geometry.

Danilov的学术论文为蓝本主要讨论了代数变量及其概型。

On the other hand, equivariant algebraic topology concerns the study of algebraic invariants of space with group actions. It is really a study of symmetries on spaces, and has always occupied a central role in mathematics.

在另一方面，等变代数拓扑关注于带有群作用的拓扑空间代数不变量的研究，其更深刻的本质在于对空间对称性的揭示，因此从来都在数学研究中占有重要的地位。

It's really the natural setting for algebraic topology because the traditional algebraic invariants (fundamental group, homolog group,etc.) arc isomorphic not only for homeomorphic spaces but for spaces of the same homotopy type. Homtopy epimorphisms and monomorphisms are special morphisms in the category of topological spaces and the initial research of them may be traceable to S.T.

同伦论的本质是利用比同胚关系更广泛的等价关系—同伦关系来对拓扑空间进行研究，这也是代数拓扑研究中一种自然的考虑，因为传统的代数不变量不仅在同胚的空间之间保持同构，而且在具有相同伦型的空间之间也保持同构。

Apparently, this formulation is also applicable to the algebraic structure whose number of generators is more than three.

对于哈密顿量生成元多于三个的量子系统，也可以用不变量理论精确求解并研究几何相因子和相关问题。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
