The symbol itself may have been suggested by the miraculous multiplication of the loaves and fishes or the repast of the seven Disciples, after the Resurrection, on the shore of the Sea of Galilee (John 21:9), but its popularity among Christians was due principally, it would seem, to the famous acrostic consisting of the initial letters of five Greek words forming the word for fish, which words briefly but clearly described the character of Christ and His claim to the worship of believers: Iesous Christos Theou Yios Soter, ie Jesus Christ, Son of God, Saviour.

符号本身可能已经提议由神奇的乘法的面包和鱼或repast的七个弟子，复活之后，对海岸的加利利（约翰21时09分），但其广受欢迎的基督徒，是因为主要是，它似乎是，以著名的acrostic构成的首字母的五个希腊字组成词鱼，其中字简略，但很明显，描述了性格的基督和他自称崇拜的信徒： iesous克里斯托theou yios SOTER的，即耶稣基督，上帝的儿子，救世主。

On the one hand, the component method is introduced into flowchart design, which can not only enlarge the depth and the connotation of the flowchart, but also extend the traditional concepts of the flowchart. By combining the component method and the objectoriented method, it will be easy to illustrate the industry flow and meet with the future requirements of the industry control software. On the other hand, the trajectory concepts in plane moving, the method of using Bezier Curve to approach the 1/4 arc to implement the arc circumrotation, the method of using graphic elements' combination to extend the expression capability, and the method of combining the graphic elements'combination, three-dimensional graphic elements and bitmaps to realize the three-dimensional effects to express the industry flow more realistic are brought forward in this dissertation.
