Firstly, the research studies the coding rule of the PDF417 barcode and designs related computer code algorithm, with making it programmed, and completes the coding part of the system software. Next, the coding and decoding principle of Reed-Solomon error-correcting code is briefly introduced. According to thecoding and decoding principle in galois field GF(929), to analyze and study its practical application with emphasis in this topic. Then, the PDF417 barcode decoding process is analyzed and studied detailed according to the barcode coding principle, with the corresponding realization method designed, improving the design in theory aspect by using material example, at the same time programming the design method to complete the decoding part of the system. Finally, validated the system program in the practical application of image information aspect, by using the nonrepeatability and the randomicity characteristic of Julia mark shape artwork.

Unfortunately, just the lack of design model to guide software design process of EC brings many issues in practices of EC. It is difficult to design reusable EC software based on the basic structure of EC. For example, the EC software aimed to solve function optimization can't be used to solve combinatory optimization without an overall modification.

由于缺少一个软件设计模型来指导演化算法的软件设计过程，仅从演化计算的基本结构出发设计出的软件很难用来求解不同种类的问题，比如针对函数优化而设计的演化算法不经大幅度的修改就不能够用来求解组合优化问题。

Therefore, the pre-fabricated functional surface containing azide groups can be covalently anchored through click-chemistry by newly designed acetylene-appended HBCs. These HBC derivatives not only possess the potential in the formation of SAM, but their alignment modes of edge-on or face-on could be controlled by tailor-made molecular design.

因此，我们设计出末端带有乙炔官能基之HBC分子，希望在预先处理并带有叠氮(-N3)官能基的基板表面上进行click-chemistry (速配组合式化学、点击化学)，利用共价键之形式将HBC分子镶嵌於基板表面，除了藉此制作出分子自组装单层薄膜之外，利用分子设计进一步控制其排列方式为edge-on或是face-on。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
