Steg B(superscript +)-Tree, which uses steganographic technologies to overcome above mentioned weakness is presented by hiding the existence of data so that an adversary could get no information about whether the protected data ever exists without correct object name and access key.

介绍一种新的着重于隐藏数据的存在性的加密手段－隐文加密（Steganography，隐写术）来对重要文件的存储进行加密，该方法采用隐文B树Steg B(上标+ Tree建立UNIX系统的文件索引，并通过隐藏表将隐文B树索引隐蔽起来，使攻击者无法知道重要信息的存在，从而使要保护的信息更安全。

In this study, combining the semantic similarity with the product taxology, a product Semantic Relevance Model is set up, the structure of this model is acquired by the training of an Industry Semantic Training Center, finally semantic information that extracted from products is integrated with current Item-Based Collaborative Filtering approach.

本文针对现有电子商务推荐系统中存在的数据稀疏性问题和系统冷开始问题，结合语义相似性以及产品分类学的方法，提出建立产品的语义关联模型，该模型的结构通过一个行业语义信息训练中心的训练得到，最终产品的语义信息被提取出来集成到现有的基于项目的协同过滤方法中。

This paper introduces the hydrological information transmission by using the Short Message Service in the GSM network. This paper firstly accounts for the components of the hydrology telemetric system.

本文主要讨论利用GSM移动通信网络中提供的短消息，数据传真业务等服务进行水情信息的传输，为水情系统的信息传输寻找一个新的途径与方法。

Comparing with the conventional modes of hydrological information transmission, the paper analyses the reality of mobile system and the protocol of Short Message Service in the GSM network. Secondly, the paper briefly introduces the realization of hydrology telemetric system. In addition, the paper shows the imperfection of Short Message Service with the other ways, for example, Data Service in the mobile network.

基因调控网络模型试图从DNA微阵列等海量数据中推断基因之间的调控关系，从而揭示复杂的生命现象，虽远未完成，但从现有实验数据中重建基因调控网络的工作可以促进在分子和遗传水平上系统地剖析细胞的功能，是功能基因组学中的重要研究内容，也是当前生物信息学和系统生物学研究的最具挑战性的前沿课题之一。

The study of transcriptive regulatory networks intends to infer regulations between genes from microarray data, and reveals the complex life of cell. Also far from being completed, the ability to recreate transcriptive regulatory networks from available experimental data facilitates the systematic dissection of cell function. The research of transcriplive regulatory networks is an important topic in functional genomics, and one of the most challenging questions in the front of bioinformatics and system biology. Several typical mathematical models and their new research developments are discussed concisely.

基因调控网络模型试图从DNA微阵列等海量数据中推断基因之间的调控关系，从而揭示复杂的生命现象，虽远未完成，但从现有实验数据中重建基因调控网络的工作可以促进在分子和遗传水平上系统地剖析细胞的功能，是功能基因组学中的重要研究内容，也是当前生物信息学和系统生物学研究的最具挑战性的前沿课题之一简要评述了几类典型数学模型的最新研究进展。

The essence of data mining is based on the function of extracting undiscovered but useful knowledge from the mass amount of, incomplete, unorderly, fuzzy and stochastic data.

数据挖掘的实施是从大量的、不完全的、有噪声的、模糊的、随机的数据中，提取隐含在其中，人们事先并不知道，但又是潜在有用的信息和知识的过程。

It is more valuable in time series analysis than unstandardized principal analysis.2 Fourier Analysis can decompose a time series signal into different frequency components, which represent different seasonal mode.3 The Phenology characteristics extracted from multi-temporal NDVI data are used for a vegetation classification.

2傅立叶分析将时间序列信号分解到不同频率成分中，各个成分分别代表了不同的周期变化模式，其中1/12频率分量概括了植被全年的单峰的季节性变化模式。 3多时相NDVI数据的时间序列分析结果中蕴含了植被的生物学信息，利用这些信息进行遥感分类。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
