In order to measure the tuning wavelength of a frequency-doubled Nd:YAG laser,strong absorption lines of molecular iodine near 532nm was adopted to provide the absolute reference for frequency stabilization.

为了精确测量倍频Nd：YAG激光器的调谐波长，采用碘分子在532nm附近的强吸收谱线作为频率稳定的绝对参考谱线，建立了以碘蒸气为标定物的激光调谐波长测定系统，实际测量了碘蒸气吸收谱线。

Online learning must be the main stream and online test will substitute the traditional paper-and-pencil test in the future. In order to respond to the coming of online learning era, how to make good use of the Internet is an important issue. Teachers can design online test questions to effectively understand students' learning performance and control their learning condition. Then teachers can provide remedial programs. Therefore, developing a flawless online test system to satisfy users' request is a critical issue both in practical and academicals.

网路学习必然是未来发展趋势，线上测验也逐渐取代传统考卷测验方式成为主流，为因应网路教学时代来临，如何善用网际网路让教师得以藉由线上测验之试题设计，而能更有效进行测验与验收学生之学习成效，且充份掌握学生之学习情况，后续即能针对能力较弱之处进行补救教学，因此，建构完善的线上测验系统以符合使用者需求，对实务界及学术界来说，都是一项很值得进行研究之议题。

One important feature of human vision mechanism is that human vision tends to group together edges that are not only geometrically and topologically related,but also similar in their appearances-the appearances of image patches around them including their brightness,color,texture cues,etc.

人的视觉系统一个重要的特点，就是人眼在获得轮廓线的时候，不仅对轮廓线两侧图像的差异及轮廓线本身几何拓扑结构上有所考虑，同时也考虑到了轮廓线周围区域图像的特性(图像的亮度、颜色、纹理等特征)的连续性。

In order to study the relatively intensity of Zeeman effect split spectrum line, the quantum number distribution and the relatively intensity are presented in detail by the analysis of Hg(546.1 nm) spilt spectrum line in the external magnetic field; the image of coherence circle is obtained by CCD, and the intensity of image is analyzed, the relatively intensity of the spilt spectrum line by image disposed is close to the theoretical result. It is concluded that the phenomenon and rule of Zeeman effect can be analyzed by CCD image technology.

为了研究塞曼效应分裂谱线的相对强度，分析了Hg(546.1nm)谱线能级在外磁场中的分裂情况，详细给出了分裂能级的量子数分布和理论相对强度；在此基础上采用CCD拍摄了分裂谱线干涉圆环的图像，并对其进行了强度分析，通过图像强度处理得到各分裂谱线相对强度与理论分析结果十分接近；表明采用CCD图像技术能较好的分析塞曼效应现象和规律。
