随着计算机技术的迅速发展和越来越广泛深入地应用于国民经济和社会生活的各个方面，随着 软件系统的规模和复杂性与日俱增，软件的生产成本和软件中存在的缺陷和故障造成的各类损失也 大大增加，甚至会带来灾难性的后果。软件质量问题已成为所有使用软件和开发软件的人关注的焦 点。由于软件是人脑的高度智力化的体现和产品这一特殊性，不同于其他科技和生产领域，因此软件与生俱来就有可能存在着缺陷。(With the rapid development of computer technology and the more extensively used in the national economy and social life in all its aspects, with the growing size and complexity of software systems, software production costs and software defects and faults caused various types of losses also increased significantly, even catastrophic consequences. Software quality has become the focus of all those who use the software and software development concern. Because the software is highly intellectual expression and product of the special nature of the human brain, unlike other areas of technology and production, so the software may be born with a defect exists.)

上传一个判断传递函数的稳定性的程序，当传函零极点位于虚轴右侧时系统不稳定，输出不稳定提示，系统稳定时输出稳定系统的传函。(Upload a function to determine the stability of the program transfer, the transfer function when the right side of the imaginary axis pole-zero when the system is unstable, unstable output prompt, the output transfer function to stabilize the system when the system is stable.)

因子分析是指研究从变量群中提取共性因子的统计技术。最早由英国心理学家C.E.斯皮尔曼提出。因子分析可在许多变量中找出隐藏的具有代表性的因子。将相同本质的变量归入一个因子，可减少变量的数目，还可检验变量间关系的假设。(Factor analysis is the study of common factors extracted from the variable group statistical techniques. First proposed by British psychologist CE Spearman. Factor analysis can identify a representative factor to hide many variables. Will be essentially the same variables into one factor, can reduce the number of variables, but also test the hypothesis that the relationship between variables.)

说明：  田纳西伊—斯特曼过程是一个基于真实化工生产过程模型。它的数据在许多领域被广泛研究和应用，比如优化控制、过程监控和故障诊断等。(The tennessee-sterman process is based on a real chemical process model.Its data is widely studied and applied in many fields, such as optimal control, process monitoring and fault diagnosis.)

提出一种新的混合数字水印算法，它利用了 两种方法最好抵制JPEG压缩。(develop a novel hybrid watermarking algorithm that exploits the best of both approaches for greater resilience to JPEG compres- sion. )
