以正弦载波的形式实现QPSK的调制解调、程序中附有详细的注释，并显示调制过程中各个阶段的结果图，经仿真验证程序正确，极力推荐下载(QPSK modulation and demodulation is realized in the form of sinusoidal carrier. Detailed annotations are attached to the program, and the results of each stage in the modulation process are displayed. The simulation results show that the program is correct and download is highly recommended.)

说明：  基于MATLAB的标准化降水指数SPI计算程序,对干旱进行识别。可对各个站点及流域批处理。可计算SPI1,SPI3,SPI6,SPI9,SPI12等(Based on the SPI calculation program of standardized precipitation index in MATLAB, drought is identified. Batch processing can be carried out for each station and basin. SPI1, spi3, spi6, spi9, spi12, etc. can be calculated)

本文讨论了iBATIS SQL Map最重要的特性。使用SQL Map，能够大大减少访问关系数据库的代码。SQL Map使用简单的XML配置文件将Java Bean映射成SQL语句，对比其他的数据库持续层和ORM框架（如JDO的实现，Hibernate等），SQL Map最大的优点在于它简单易学。要使用SQL Map，只要熟悉Java Bean，XML和SQL，就能使您充分发挥SQL语句的能力。(This article discusses the iBATIS SQL Map of the most important features. Using the SQL Map, can greatly reduce the code to access a relational database. SQL Map using a simple XML configuration file will be mapped into a SQL statement, Java Bean, compared to other databases continuous layer and ORM frameworks (such as JDO implementation, Hibernate, etc.), SQL Map of the biggest advantages is that it is easy to learn. To use the SQL Map, as long as the familiar with the Java Bean, XML, and SQL, will enable you to give full play to the capacity of SQL statements.)
