==How to use processing to do creative work==

===Processing for GraphPaper===
1.1 GraphPaper
This book will teach you how to program in the context of computational media, and it will use the development environment Processing (http://www.processing.org) as the basis for all discussion and examples. But before any of this becomes relevant or interesting, we must first channel our eighth grade selves, pull out a piece of graph paper, and draw a line. The shortest distance between two points is a good old fashioned line, and this is where we begin, with two points on that graph paper.

Figure 1.1 shows a line between point A (1,0) and point B (4,5). If you wanted to direct a friend of yours to draw that same line, you would give them a shout and say “draw a line from the point one-zero to
the point four-five, please.” Well, for the moment, imagine your friend was a computer and you wanted to instruct this digital pal to display that same line on its screen. The same command applies (only this time you can skip the pleasantries and you will be required to employ a precise formatting). Here, the instruction will look like this:
    line(1,0,4,5);
Congratulations, you have written your first line of computer code! We will get to the precise formatting of the above later, but for now, even without knowing too much, it should make a fair amount of sense. We are providing a command (which we will refer to as a “function”) for the machine to follow entitled “line.” In addition, we are specifying some arguments for how that line should be drawn, from point

==黄铜材质的优点与劣势==
===黄铜简介===
黄铜是用铜及锌的合金制造成的物体，因色黄而得名。铜含量56%~68%的黄铜，其熔点为934~967度。因其优秀的机械及耐磨性能在工业上有广泛应用，常见于精密仪器以及工业零件制造。 
===黄铜优点===
强度硬度高，可应付冷/热加工，焊接以及抗腐蚀性能也良好。价格便宜，方便批量生产。高韧性与易切削性也适合产品制造，其可塑性让铜材适合制作造型多变的艺术品。耐酸碱性意味着使用寿命也长。
===缺点===
含铅量偏高，同时有腐蚀破裂倾向，易开裂。
