A two-component carbon tetrachloride system and a two-component aqueous system have been treated with the proposed strategy where only 21 calibration samples are needed, and the result showed that the predictive ability was not obviously impaired for the former system while being clearly strengthened for the latter one in comparison with a conventional way that required a calibration set of 100 samples.5 An unlooked-for experimental observation that in near-infrared spectroscopy the second overtone of aniline adsorbed by 13X molecular sieve nearly disappeared led us investigate a fundamental problem: the behavior of NIR when the outside space surrounding a molecule is too small to allow the molecule to vibrate freely.

同时，最小相关样本设计能进一步减少所需的校正样本数，且能提供更多合适变量以建立多元校正模型。这两方面的改进使模型的预测能力得以提高，其预测精度即使在水体系中也有明显的改善。五、近红外漫反射光谱在线非接触监测气-固吸附过程中出现了一个意外现象，即在近红外光谱上，被13X分子筛吸附的苯胺的二级倍频几乎完全消失了。这促使笔者深入探讨了近红外光谱的空间效应(当一分子被一足够小的刚性空间限制时，其振动的受限导致一级倍频和二级倍频强度均减少，并且后者减少的程度比前者更大)。

In this paper we've compared several predicate of first order operators, and proposed an improved algorithm which is based on the automatic double threshold value improvement algorithm based on the maximum inter-cluster distance and intra-cluster variance ratio.

This dissertation is mainly concerning digital image watermarking problems. In Chapter 2, a detailed survey on digital image watermarking is presented. In Chapter 3, an optimal scheme is proposed to use Human Visual System model to compute masking function. It will be used to control the strength of watermark signal for optimal embedding. In Chapter 4, we propose a novel watermarking scheme based on lattice vector quantization.

本文讨论了数字图像水印及其在多媒体安全中的应用，主要围绕下列问题进行研究和创新： 1、优化的水印嵌入模型：本文对基于直接序列扩频技术的水印算法进行了改进，根据人类视觉系统感知模型，提出了优化的水印嵌入模型，在不可感知性条件的限制下，使水印的鲁棒性达到最高。

It will be used to control the strength of watermark signalfor optimal embedding. In Chapter 4, we propose a novel watermarking scheme based on lattice vectorquantization. Some important transform coefficients of the original image are firstlymapped into the nearest neighboring lattice points by using lattice vector quantizer,then watermark signal is added to the lattice points.

In order to improve the success ratio and velocity of iris location, an iris location algorithm based on morphological operators was developed.

为了提高在图像质量较差时的虹膜定位性能，改善虹膜定位的成功率和速度，在对Daugman算法改进的基础上，提出了一种基于形态学算子的虹膜定位算法。

Based on reviewing the banking reform experience of Eastern European countries, we propose seven propositions on China's banking sector reform and empirically vitrify seven propositions using data from 21 banks between 1999 and 2006 ,then draw final conclusions: foreign banks entry lower the profit rate of hosting country banking industry in short-term, improve host country banking's risk management skills

本文在综述东欧国家银行业改革经验的基础上提出中国银行业改革的七个命题，并用中国24家银行1999-2006年间的数据构建模型进行检验，最后得出结论：短期内外资银行进入导致东道国银行业利润水平下降、风险管理水平上升，在中国的背景下可以认定这是外资银行积极作用开始发挥；外资银行机构数量的增加和持股比重的上升都能刺激中国银行业效率的改进，但是外资银行持股比重的影响更具普遍性；不同类型银行对外资银行进入的反应存在差异，国有商业银行反应比较迟钝而股份制和城市商业银行反应比较迅速。

At the same time, it exposed lots of drawbacks: first of all, how to extract stable personal characteristic information as much as possible from voice; secondly, how to improve training method to get better model according to existing feature; thirdly, how to use the voiceprint feature in mobile environment.
