This paper mainly uses the technologies and methods of digital image processing and computer grogram language to research and develop a glass-crack inspecting system. We can judge whether the image is a crack or not from the digital image processing methods that the inspecting system applies us.

本文主要利用数字图像处理技术及其方法结合计算机编程语言来研究一套检测玻璃瓶裂纹的系统，利用该检测系统提供的一些数字图像处理方法可以快速准确的判断出该图像是否为裂纹图像。

On-line handwritten numeral recognition, and I hope to learn digital image processing of some help.

联机手写数字识别，希望对学习数字图象处理的人有所帮助。

We choose the TMS320VC5402, digital signal processor, as the computing unit, filtering the sampled signal, truncating the harmonic whose frequence greater than 2500hz, then we use the window-interpolation FFT algorithm to get the refined frequence, amplitude, phase of harmonic in sampled voltage and current, other parameter such as harmonic ratio, active power, reactive power, power factor, three-phase unbalance can be also computed base one the result of window-interpolation FFT.

选用TMS320VC5402高速数字信号处理器作为运算单元，先对采样信号进行数字滤波，去除50次以上谐波分量，然后应用加窗双峰插值FFT算法计算电压电流的各次谐波频率、幅值和相位，以及谐波含有率、有功功率、无功功率、三相不平衡度等各项电能指标，同时利用锁相环电路硬件跟踪电网频率以减小采样失步度。

The secret hash digital signature is a new siganture method that combines the ideas of RSA public-key algorithm, MD5 one-way hash function and permutation code at the same time.

保密散列数字签名算法利用RSA公钥密码体制的原理、MD5单向散列函数和排列码加密的思想，构造了一种能够快速实现数据保密、数字签名的签名方案。

Diesel fuel is the company's second-largest expense(drivers'wages is the largest),and the freight hauler wanted to find a way to reduce that.part of the answer lay,as it often does,in IT.

这个公司花了在2004年花费了2.5亿美元的燃料，这个数字比前年的数字增长了40 ％，，柴油机的燃料是这个公司的第二大开支（司机的薪水是世界上最大的），因此货运运输公司想要找到一种减少这部分开始的答案，作为它经常采取的方式。

This paper explores the application of the modern digitized technology to the teaching of the Electromagnetism. By the numerical calculation and digital simulation, the electromagnetic field of an uniformly charged ring, the non-linear vibration of charged particle in an uniformly charged ring and the uniform area of Helmholtz coils are discussed.

本文探讨现代数字技术在电磁学教学中的应用，通过数值计算和数字模拟，深入讨论了环形源电磁场的空间分布、带电粒子在带电圆环电场中的非线性振动以及亥姆霍兹线圈内的均匀磁场问题。

In theory, every problem of involving morphological analysis and examination can be solved with digital image processing technology. Because there are irregular form structures, uncertain space positions and impure samples of the human helminth eggs, digital application and research is underdeveloped in parasitology. The recognition and analysis of human helminth eggs is unable to be performed by means of automatic instrument as blood cell. As a result, they have been observed and distinguished under the microscope through the naked eye for a long time.

从理论上说，凡是牵涉到形态分析和检测的问题都可以用数字图像处理技术来解决，但由于人体寄生虫虫卵的不规则的形态结构、空间方位和标本杂质较多等原因，数字图像技术在寄生虫学上的应用和研究很少，寄生虫虫卵的识别无法象血细胞分析一样用自动化仪器进行，长期以来只能依赖人眼在显微镜下进行观察分辨。

Hereinto, the differentiating obstacle system is necessary composing part of the digital agriculture research vehicle and would ensure the vehicle safely running in the course of its working.

其中，障碍物判别系统是数字农业研究平台车的必需部分，将保证数字农业研究平台车在运动工作过程中的安全行驶。
