At last, we point out that soft sensor technology must used to build an information warehouse for the whole enterprise, combined with data fusion, data warehouse, data rectification and other related technologies. The main contributions of this dissertation are as follows: The background, requirement, and application situation of soft sensors are expounded, the theories, methods and skills of soft sensing technology are analyzed, and the fruits and problems in current soft sensor technologies are summarized. Some new methods of soft sensor is proposed: A principal component analysis-based secondary variable selection method are proposed; A new conception which modeling data should have gross error detection is addressed, and then a cluster analysis-based modeling data gross error detection method is given.

本文的主要贡献有：对软测量技术根据实践的要求进行了一定的理论研究，针对具体问题提出了新的方法：讨论了辅助变量选择问题，研究了基于主元分析的辅助变量选择方法，该方法克服了传统方法只能利用数学模型产生的仿真数据进行最优辅助变量选择的缺点，可以根据历史数据进行辅助变量选择；提出了建模数据显著误差侦破的概念，指出传统的显著误差侦破研究的是已知过程数学模型的情况，而建模时数学模型是未知的，但是直接来自现场的数据并不能保证不含显著误差，并用基于聚类分析的方法解决了该问题，该方法利用聚类分析原理，直接面对过程数据，不需以过程模型为基础，在此基础上给出了软测量建模过程中样本数据的处理方法。

After two-cluster testing,branch length testing and relative rate testing ,two sequences(Melantitta nigra and Aythya americana) of 15 Cty b sequences were deleted because thek evolutionary rate were heterogeneous. The divergence between Anseriformes and Galliformes was chosen as an anchor point. Nucleotide sequence and amino acid sequence of 13 sequences data set was used to calibrated Anatidae molecular clocks. The results indicated that amino acid sequence is better than nucleotide sequence when divergence time is calculated with two kinds of sequences. The reliable divergence time of Anatidae were estimated with """"1+2TiTv"""" model.

经过二簇检验、分枝长度检验和相对速率检验，删除2条速率不恒定的序列后，用剩余的13条序列，以鸡形目与雁形目的分歧时间(89.8MYA)为锚定点，用顺序标定法标定鸭科鸟类分子钟的分析结果表明，用&1+2TiTv&分析得到的鸭科鸟类的分歧时间比较可靠；氨基酸序列用泊松校正模型和Γ模型估计的分类单元间的分歧时间则比较一致，表明氨基酸序列更适合用于鸭科鸟类分子钟的研究；用同一基因标定分子钟时，较长序列得到的结果标准误比较小；与核苷酸序列相比，氨基酸序列更适于用作分子钟的标定。

Study of the causes of MCS intensification and rainstorm shows that( 1) just before the heavy rains occur, there are high temperature, considerably wetness and unsteady convective stratification in the air over the rainstorm-hit area, in addition to significant increase in convectively efficient potential energy, condensation height and decrease in the height of free convection – all these favor the happening of the heavy rain,(2) the mergence of meso-βcloud clusters leads to the MCS such fast growth as to produce rainstorm,( 3) the two lines of cumuli in the north and west correspond, separately, to two convergences on the surface wind field, with stronger convergence at their meeting point responsible for such intense development of meso-βcloud cluster as to bring about torrential rains.

分析MCS加强和产生暴雨的原因表明，首先，暴雨发生前夕暴雨区域具有高温、高湿和对流性不稳定层结，并存在明显的对流有效位能增加、抬升凝结高度及自由对流高度降低的现象，有利于暴雨发生。第二，β中尺度云团之间的合并，使MCS迅速增长，产生暴雨。第三，北、西两条积云线分别与地面风场中的两条辐合线相对应，在它们交汇处的较强辐合导致β中尺度云团强烈发展产生暴雨。

This paper analyzes the principle of the LP-LFC process,presents the physical and mathematical models of mould filling of the new process. The patterns including window-plate, ladders cluster, electromotor frame and exhausting manifolds are poured using LP-LFC process with AZ91D alloy, and the mould filling course is tracked with electrode touch point method.
