8) 输入该过程需要进行的循环次数，按ENTER确定，进入下一过程的编辑。

9) 进行下一过程的各步编辑，每个过程最多只能设置10步。

10) 若要结束该过程，保持各参数的设置为零，按ENTER

11) 输入循环次数，按ENTER确认，进入下一过程编辑。

12) 根据需要，进行其他“过程”和“步”的编辑，任何“过程”或“步”要结束时，则最后“过程”和“步”中的参数保持为零，再按回车。

13) 输入循环次数，并输入程序结束后保持的温度，若没有输入保持的温度，则设备冷却至室温，整个过程就结束。

接下来，按ENTER进入“保存”画面。

14)按ENTER保存程序。

5.5编辑修改一个存在的程序

当修改并另存为一个程序时，可以使用COPY功能。详见5.7节。程序的名字也可以进行修改、保存，即使程序中的数据没有进行修改。在修改过程中近CONTINUE，可以进入高级编辑，详见5.9节。在程序运行过程中，可以对其他的程序进行修改、编辑。例5.2编辑、修改一个已有程序：

用←→选择目录，用↑↓选择程序，按ENTER即完成删除，按STOP或MENU取消

4.按ENTER，退出高级编辑，返回编辑模式，屏幕上会有〈ADV〉显示

▲ 温度高级编辑示例

▲ 温度高级编辑能使退火温度升或降

下面例子：25个循环中，前4个循环的退火温度为65℃，中间16个循环，依次每个循环的退火温度减1℃，最后5个循环的退火温度为50℃

1) 在编辑模式中，移到想要进行高级编辑的温度。

2) 按CONTINUE进入高级编辑，用↓键TEMP领域，用→选择升或降，用数字键输入数值。

3) 用↓键返回，屏幕会出现〈ADV〉字符。

▲ 改变升降温速率

默认的RAMP为0.00℃/sec，表示以最快的速率升降温，设定值可以在0.01~9.99℃/sec之间变化，但目前模块的技术只允许最高3.00℃/sec,该项技术是为某些有特殊要求的退火、延伸而设计的。

5.9梯度功能

梯度功能只有配备梯度模块时才有效，若用非梯度模块运行梯度程序，屏幕会如下显示：

1998.12.1前购买的仪器需升级(该部分略)

梯度程序编辑示例

1) 在程序的编辑过程中的退火该一步骤，可以先设定一个最低退火温度，然后按CONTINUE进入高级编辑

2)

3) 输入梯度范围1~15℃，ENTER确定。 梯度设置成功后，在屏幕有〈G：15〉显示，G表示梯度，15表示梯度范围为15℃，TEMP 45：00表示最低温度为45℃，这样整个温度在45℃～60℃之间有一个梯度变化。但整个退火温度的范围只能在30℃～70℃之间设置，否则系统会提示“TEMP/GRAD INVALID”要求重新输入，若梯度15℃，会显示“？？”错误。要求重新输入梯度范围。

梯度计算的显示

你可以从电泳结果得出一最佳退火温度(从梯度温度计算的显示中)

1) 从主菜单进入OPTS选项，按ENTER进入

2) 移动光标至CALC，按ENTER进入，显示BLOCK型号，最低温度45℃，梯度范围15℃。

4) 分两个屏幕显示C1~C12的12列的温度变化。

5) 按ENTER进入下一屏幕，或用↑↓进行屏幕间的互换，按ENTER返回主菜单。

5.10高级编辑

高级编辑可以建立复杂的程序以提高实验数据，如：随着循环的递增，使时间和温度进行相应的递增和递减；在程序编辑过程中，按CONTINUE进入高级编辑，程序已进行高级编辑，则在屏幕上有〈ADV〉显示。用数字键输入高级编的参数，按ENTER确认，若要删除已有的高级编辑，只要保持高级编辑中各参数为零，按ENTER

第1章 绪论

1.1 分拣系统发展

分拣是把很多货物按品种从不同的地点和单位分配到所设置的场地的作业。按分拣的手段不同，可分为人工分拣、机械分拣和自动分拣。

目前自动分拣已逐渐成为主流，因为自动分拣是从货物进入分拣系统送到指定的分配位置为止，都是按照人们的指令靠自动分拣装置来完成的。这种装置是由接受分拣指示情报的控制装置、计算机网络，把到达分拣位置的货物送到别处的的搬送装置。由于全部采用机械自动作业，因此，分拣处理能力较大，分拣分类数量也较多。

随着社会的不断发展，市场的竞争也越来越激烈，因此各个生产企业都迫切地需要改进生产技术，提高生产效率，尤其在需要进行材料分拣的企业，以往一直采用人工分拣的方法，致使生产效率低，生产成本高，企业的竞争能力差，材料的自动分拣已成为企业的唯一选择。针对上述问题，利用 PLC 技术设计了一种成本低，效率高的材料自动分拣装置，在材料分拣过程中取得了较好的控制效果。

物料分拣采用可编程控制器PLC 进行控制，能连续、大批量地分拣货物，分拣误差率低且劳动强度大大降低，可显著提高劳动生产率。而且，分拣系统能灵活地与其他物流设备无缝连接，实现对物料实物流、物料信息流的分配和管理。 其设计采用标准化、模块化的组装，具有系统布局灵活，维护、检修方便等特点，受场地原因影响不大。同时，只要根据不同的分拣对象，对本系统稍加修改即可实现要求。

PLC控制分拣装置涵盖了PLC技术、气动技术、传感器技术、位置控制技术等内容，是实际工业现场生产设备的微缩模型。

应用PLC技术结合气动、传感器和位置控制等技术，设计不同类型材料的自动分拣控制系统。该系统的灵活性较强，程序开发简单，可适应进行材料分拣的弹性生产线的需求。本文主要介绍了PLC控制系统的硬件和软件设计，以及一些调试方法。

三．语法填空(1x15=15分)

Directions: Read the following two passages. Fill in each blank with one proper word or the proper form of the given word to make the passage coherent. Make sure that your answers are grammatically correct.

(A)

There is a photo hanging above my desk. Whenever I look at that photograph, it takes me back to those early years 16. every new experience was important for me. I can still remember the shouts of the spectators as I 17. (go) out onto the sports field with my classmates. Two days 18. (early). I had qualified for the finals of the 100 meters. Now 19. (look) around, I was determined to win.

While I was walking across to the start, I began to feel more and more nervous. I looked around and saw my proud parents waving enthusiastically. My heart was beating fast when I lined up with the other eager competitors. I look some deep breaths and waited for the signal. Then the starting signal 20. ___________(give) and I set off down the track.

I ran as fast as I could, not looking at anything but the finishing line. By the time I crossed the line, I was so exhausted that I 21. hardly breathe. As soon as I heard the result 22. (announce), I realized I had won! Overjoyed, I collapsed on the soft grass with a broad smile on my face.

“Well done!” said the Headmaster later, as I was presented with the winner’s certificate. I had never felt so happy and proud in my life.

(B)

One of the first questions young children ask is “Why?” It is human nature to want 23 (find) out why things are the way they are. You can find out “Why” by turning the question into a hypothesis (假设) for 24. experiment. 25. example, suppose you have been trying to grow tomato plants, but insects keep destroying 26. . Someone tells you that 27. (put) large strips of colored cloth around the plants will keep insects away. Your question might be “Do certain colors of cloth keep insects away?” Then you’d begin your experiment. The first step would be to place different-colored strips of cloth around all of the plants except one. Then, as regular intervals, you would observe and record and note 28. the plant had any insect damage or not.

This experiment may prove that the answer to your question is “No, it is not different-colored strips of cloth 29. keep away insects.” Or you may find that answer is “Yes, certain insects are kept away by blue cloth, but not yellow cloth.” ......30. you have found, you are well on your way to understanding how you can use scientific thinking to solve a problem in you own life.
