绝对值

On the whole, we do as follows: Firstly, we list some conceptions and lemmas for later use. Secondly, we inducted the absolute value norm in the two-dimensional vector interspace, and also proved the two-dimensional vector interspace is a Banach Interspace. Thirdly, we define two-dimensional vector-valued functions on a interval by the definition of -fine partitions in part 1. Then, some sufficient and necessary conditions of integrabel are given, and discuss the property of the integral on two-dimensional vector-valued functions.

主要包括以下内容：在第一部分，我们介绍了本文所用到的几个基本概念和引理；第二部分，我们在二维向量空间中引入了绝对值范数，并且证明了二维向量空间是一个Banach空间；在第三部分中，通过第一部分关于-精细分划的定义，我们给出了在某区间上二维向量值函数积分的定义以及可积的充分必要条件，并讨论了二维向量值函数积分的一些性质。

The absolute value of the number x.

And it is suggested that this is a good tool in identification of the flow regimes and not easily influenced by the absolute pressure value.

实验表明，采用脉动能作为特征值不易受压力绝对值的影响，在微管道中气液两相流流型的识别过程中取得了比较好的结果。

The reverse permeability coefficients of CO2 is affected by pressure difference and decreases evidently with the increase of the absolute value of pressure difference.

Both a reversion and an increase of the absolute value of specific rotation in the transformation from MALM to PMALM- b -PSF- b -PMALM were observed,which were probably caused by some kind of stereostructure of the main chain formed during the polymerization due to the intermolecular hydrogen-bonding.

共聚物在聚合过程中旋光度发生了反转，且比单体的旋光度的绝对值显著增加，这可能是由于聚合过程中分子主链感应出了手性的二级结构诱导出手性放大效应引起的。

Finally, read the literature on the basis of conclusions, based on the theory of the former has selected some of the major factors research, and the scale of absolute and relative proportions through regression analysis to compare, from the selection of the service industry a significant competitive edge The impact of factors.

最后，在参阅相关文献结论的基础上，依据前文的理论分析，选取了一些主要的因素进行研究，并将规模绝对值和比重相对值通过回归分析进行比较，从中筛选对服务业竞争力有显著影响的因素。

The issue is not that consumption is not rising fast enough on an absolute scale. Rather, as in Japan, a development strategy that brought enormous success has been taken to an unhealthy and unsustainable extreme.

问题不在于消费开支的绝对值增长不够快，而是一种曾造就了巨大成功的发展策略被用到了不可持续的有害极至，日本也是这样。

Based on the further evolvement of the improved chaotic system with constant Lyapunov exponent spectrum, by introducing an absolute term in the dynamic equation, a novel chaotic attractor is found in this paper.
