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

Then we used spot 3 to test the performance of the network, at the same time, two other networks were built for comparation with the BBP network we have set.

结果表明，网络训练集的相关性达0.8867，平均绝对误差和平均绝对方差分别为15.07和377.4，确证集两组数据的预测精度为3.5%和16.5%。

To reduce the receiver complexity,a differential space-frequency transmit diversity scheme was developed with a noncoherent detection method based on the frame structure of the time domain synchronous-orthogonal frequency division multiplexing system.

在采用相干检测方法的发射分集方案中，进行信道估计需要付出很高的代价，为了降低接收端的实现复杂度，根据时域同步正交频分复用系统结构的特点，提出了差分空频发射分集及相应的非相干检测方法。

The positive region based on radix sorting is used to get the positive region condition attributes set of decision attributes and the condition attribute set which excludes one of the condition attributes of decision attribute positive region. Then the difference between the two radices of positive regions is calculated to judge whether the condition attribute is a core attribute, thereby all the condition attributes are judged and the required core is quickly acquired.

采用基数排序思想计算正区域，分别得到决策属性正区域的条件属性集和除决策属性正区域的一个条件属性之外的条件属性集，并且计算这2种属性集的基数之差，以判断该条件属性是否是核属性，依次判断所有条件属性，从而快速获得所需要的核。

The beach body of Lower Triassic Feixianguan Formation in northwestern Sichuan can be divided into platform marginal oolitic beach and intraplatform point beach. The water is relatively deeper at the forming of most of platform marginal oolitic beach which is not transformed by the diagenesis of fresh water and mixed water and has poor reservoir properties. However, a part of oolitic beach formed under shallow water environment, and it is transformed by the diagenesis of fresh water and mixed water and well dolomitized, which can form excellent reservoir.

川西北下三叠统飞仙关组滩体分为台地边缘鲕粒滩和台地内点滩2种类型，多数台地边缘鲕粒滩形成时水体相对较深，未经大气淡水和混合水的成岩改造，储集性能较差，局部鲕粒滩形成时水体较浅，在经过大气淡水和混合水的成岩作用改造后，白云石化好，可形成储集性能极好的储集体；台地内点滩白云石化较好，储集性能也较好，但分布狭窄，厚度较薄，无规律可寻。

HVAC piping design with valve selection 1, chiller plant, cooling water between inlet valve design; 2, before the butterfly pumps, filters, pumps after the check valve, butterfly valve; 3, sets, water separator pressure differential between the bypass valve; 4, set, divider into the returning pipe valve 5, the level of dry pipe valve; 6, valve air handling units, filters, electric two-pass or three-way valve 7, fan coil valve (or plus electric two-way valve) Note: The valve is typically used when the diameter is less than 150mm used Handle Butterfly Valve (D71X, D41X); diameter greater than 150mm used worm drive butterfly (D371X, D341X).
