On a monolithic integrated circuit university test-bed, the product design chart of Zhou Xingfa present half-finished product. 在一台单片机综合实验台上,周兴发现一款半成品的产品设计图。 In the product design request according to blueprint, Zhou Xing attempts to complete it. 按照图纸上的产品设计要求,周兴尝试着完成它。 „The second foot needle, should establish in this position, avoids disturbing.” “第二脚针,应该设置在这个位置,避免干扰。” „It is not right, this piece of electric circuit has the issue, will short-circuit! Here should add together the electric capacity again, un, perfect, this piece of electric circuit passed.” “不对,这片电路有问题,会短路！这里应该再加一块电容,嗯,完美,这片电路通了。” „The electric circuit of this control module should only walk, ha, inserted successfully!” “这个控制模块的电路应该这样走,哈,嵌入成功了！” „...... ” “……。” Unknowingly, Zhou Xingquan body body and mind puts into during the design of circuit diagram, forgot the time to pass, neglected all. 不知不觉,周兴全身身心地投入电路图的设计当中,忘了时间流逝,忽视了身边的一切。 The time 1 0.1 drops of past, Zhou Xingzhan before the laboratory bench, writes to draw to the design paper, gradually the design of perfect product design chart. 时间一点一滴的过去,周兴站在实验台前,对着设计图纸写写画画,逐渐完善产品设计图的设计。 „Un, here probably a little issue?” Zhou Xing a brow wrinkle, looks that is going to complete the blueprint to discover is not right, but actually cannot seek out the issue to be. “嗯,这里好像有点问题？”周兴眉头一皱,看着将要完成设计图发现了一丝不对劲,但却找不出问题所在。 „, That side the frequency division module had problems, that piece of electric circuit must change.” A sound reminded suddenly behind in Zhou Xing: “咳,分频模块那边出问题了,那片电路要改一下。”一个声音突然在周兴身后提醒道: „Right, right, is here issue, this piece of electric circuit must be connected including the above.” Zhou Xing one happy, after such a reminder, he discovered immediately issue is at: “对,没错,是这里的问题,这片电路要连上。”周兴一喜,经这么一提醒,他立即发现了问题的所在: „Uncle Liu, you come!” The week is popular improves the circuit diagram, turns around to send regards: “刘伯伯,你来啦！”周兴改好电路图,转身问候道: „Un, has stood for a half hour! I think that you draw it!” Liu strong look looks at Zhou Xing complex, the nod said: “嗯,已经站了半小时啦！我看着你把它画完的！”刘强神色复杂地看着周兴,点头道: Zhou Xingsao electronic wall clock, unknowingly, has crossed quick one hour. 周兴扫了电子挂钟一眼,不知不觉,已经过了快一个小时。 The week is popular suddenly, looks at Liu strong, the non- meaning said: „Uncle Liu, the hand was itchy for a while, moved your blueprint! I....” 周兴恍然,看着刘强,不意思地说:“刘伯伯,一时手痒,动了你的设计图！我…。” „Doesn't matter, done good, your foundation is very good, is meticulous, good of layout design, otherwise I broke you early.” Liu strong beckons with the hand, interrupts Zhou Xing the words: “没关系,做的不错,你的基础很好,思维缜密,图纸设计的不错,不然我早打断你了。”刘强摆了摆手,打断周兴的话道: „The relations that but, perhaps experiences, this blueprint some places are insufficient.” Zhou Xing just about to opens the mouth to express gratitude, Liu strong continued suddenly: “不过,也许经验的关系,这份设计图还有些地方不足。”周兴刚要开口表示感谢,刘强突然继续说: „Does Uncle Liu, where have the issue?” Zhou Xingda the eyes stare, asked puzzled: “刘伯伯,哪里有问题？”周兴大眼一瞪,不解地问: Liu strong shows a faint smile, with beginning a stroke in blueprint two place respective checks a circle. 刘强微微一笑,拿起笔在设计图的两个地方各自勾了一个圈。 Liu Qiangzhi a circuit diagram of small circle is explaining to Zhou Xing: „The design of this piece power supply modular circuit is unreasonable, will create to consume energy to increase, affects the composite specification!” 刘强指着一个小圈的电路图向周兴解释道:“这个片供电模块电路的设计不合理,会造成耗能增加,影响整体性能！” hears word, the week is popular the facial color slightly changes, the vision stares at the position that Liu strong is referring to stubbornly, the brain racing, ponders crazily. 闻言,周兴面色微微一变,目光死死盯着刘强所指的位置,脑筋急转,疯狂思考起来。 „Uncle Liu , because the feed circuit does use the relations of individual device electric circuit?” The week is popular catches the eye to look that Liu strong asked: “刘伯伯,是因为供电电路采用分立元器件电路的关系吗？”周兴抬眼看着刘强问: Being a promising young man, is really intelligent! 孺子可教,真聪敏啊！ Liu strong looks at Zhou Xing satisfied, was sighing with emotion one at heart. 刘强满意地看着周兴,在心里感慨了一句。 „Right, must have many matters needing attention when the designa circuit: When designa circuit must reduce the number of primary device as far as possible, with the IC design, must pay attention to the radiation issue regarding large power component as far as possible, internally, outside shared signal source must add the isolation level,...... ” Liu strong replied for Zhou Xingjie in detail: “没错,在设计电路时要有很多注意事项:设计电路时要尽量减少元器件的数目,尽量采用集成电路设计,对于功率大的器件要注意散热问题,对内,外共用信号源的要加隔离级,……。”刘强详细地为周兴解答道: „Un, I understood, that another place is what issue! I feel no issue!” Zhou Xingshen inspires, some are not convinced asked: “嗯,我明白了,那另一个地方是什么问题！我觉得没任何问题啊！”周兴深吸了一口气,有些不服气地问: The dual purpose, Zhou Xing pondered both issues wholeheartedly the past that the place issue that first encircles can say, the place of second circle did not have the truth, did not have the issue obviously! 一心两用,周兴将两个问题都思考了一遍,第一个圈起的地方问题能说的过去,第二个圈的地方就没道理了,明明没问题啊！ Liu strong shows a faint smile, explained: „This piece of electric circuit, if designs like this, the overall cost will enhance some! Slightly is popular, we run the factory, if a cost of circuit wafer design many that several cents, then converts, our profits must minus hundreds of thousands!” 刘强微微一笑,解释道:“这片电路如果这样设计的话,整体的成本会提高一些！小兴,我们是开工厂的,一片电路板设计的成本如果多那么几毛钱,那么换算下来,我们的利润要少掉十几万呢！” hears word, the week is popular slightly one dull, has not thought that can be this reason. 闻言,周兴微微一呆,没想到会是这个原因。 „Good! Uncle Liu, my some issues consults to you!” Zhou Xing understands nods, shift topic that the moment cannot delay: “好吧！刘伯伯,我有一些问题向您请教！”周兴理解地点了点头,一刻不能耽搁的转移话题道: „Ok, you asked!” Liu Qiangxiao nod of: “行啊,你问吧！”刘强笑着点了点头: „Before, I used the 89s 51 chip to do the experiment in the development board, the procedure/program read in normally, but the work was not normal, phenomenon: the p1.0 mouth does to take the counter- experiment, led is not normal. Why is this?” Zhou Xingqiu solves asked: “之前,我用89s51芯片在开发板做实验,程序写入正常,但是工作不正常,现象:p1.0口做取反实验,led不正常。这是为什么？”周兴求解地问: „Timer establishment has the issue, the timer interruption symbolized whether reset?” Liu strong tastes have the reason saying: “定时器设置有问题,定时中断标志是否清零了？”刘强一口道出原因道: Zhou Xing eyes one bright, immediately wants to understand the reason , to continue to ask: „Uncle Liu, I uses io to simulate the i2c stored datum, the first secondary storage data does not have the issue, but if conducts the second secondary storage again, the data of first secondary storage will make a mistake, I could not find the reason continuously,....” 周兴眼睛一亮,立即想明白了缘由,继续问:“刘伯伯,我用io模拟i2c存储数据,第一次存储数据没问题,但是如果再进行第二次存储,第一次存储的数据会出错,我一直找不到原因,…。” „The procedure/program that you compile presented bug, programmed me to have a look.” Liu strong is knitting the brows, gives Zhou Xingdao the pen: “你编写的程序出现bug了吧,把程序写我看看。”刘强皱着眉,将笔递给周兴道: „Good!” Zhou Xingjie starts writing, brushes several, writes a fleeing programming code on the paper rapidly. “好！”周兴接下笔,刷刷几下,迅速将一窜程序代码写在纸上。 „Procedure right, you experiment does the port meet wrong?” Liu strong is staring at Zhou Xingxie the procedure/program, ponders for a long time, wants to ask intangibly: “程序没错,你实验的时候端口有没有接错啊？”刘强凝视着周兴写的程序,思考许久,想不明白地问: hears word, the week is popular slightly one dull, shakes the head. 闻言,周兴微微一呆,摇了摇头。 „I will test to have a look next time again, Uncle Liu, an issue....” Zhou Xing jumps over this issue to continue, asked: “我下次再实验看看,刘伯伯,还有一个问题…。”周兴跳过这个问题继续,问: „Un, you said!” Liu strong nods reluctantly: “嗯,你说吧！”刘强无奈地点了点头: „Issue is this, I experiment....” “问题是这样的,我实验…。” Looks look that Zhou Xing is full of the intellectual curiosity, Liu strong is unable to reject, again and again answered Zhou Xing the issue. 看着周兴充满求知欲的眼神,刘强无法拒绝,一而再,再而三的回答周兴的问题。 Two people one asked questions and other answered, unknowingly, the time passed for one hour. 两人一问一答,不知不觉,时间过去了一个多小时。 „Rumble”, the closed laboratory glass front door suddenly opens, Liu strong of depression escapes from the laboratory runs. “隆隆”一声,紧闭的实验室玻璃大门突然自行打开,精神萎靡的刘强从实验室里逃跑似的跑出来。 Liu strong runs, rushes to Zhou Wenhai's office, takes up the drinking glass on desk to fill toward own mouth, a throat agitation, 刘强一路小跑,跑到周文海的办公室,拿起办公桌上的水杯就往自己的嘴里灌,喉咙一阵鼓动, „Strong elder brother? Were you? This water....” Zhou Wenhai who is revising the document, stares, this water was he has drunk! “强哥？你这是怎么了？这水…。”正在批改文件的周文海,不由一愣,这水是他喝过了啊！ „! Almost died of thirst I!” The water in Liu Qiangjiang drinking glass tosses down, called one satisfiedly: “哇！差点渴死我了！”刘强将水杯里的水一饮而尽,满足地叫了一句: „Can I? Also is not your precious son, you hurry to get him!” Liu Qiangnu is staring Zhou Wenhai, said angrily: “我能怎么了？还不是你的宝贝儿子,你赶紧把他领回去吧！”刘强怒瞪着周文海,怒气冲冲地说: „Slightly is popular? How slightly is popular? Did he cause trouble?” Zhou Wenhai is startled, the anxious sound asked: “小兴？小兴怎么啦？他又闯祸了？”周文海吃了一惊,急声问: What must use „” this character! Slightly was popular has not caused trouble very for a long time probably! Zhou Wenhai suddenly some thinking of longing. 什么要用“又”这个字呢！小兴好像已经很久没闯祸了唉！周文海突然有些怀念的想。 „Slightly is popular has not caused trouble, but....” Liu strong looks the awkward color, some are difficult. “小兴没闯祸,只不过…。”刘强面露尴尬之色,有些难以启齿。 „Without causing trouble that is good, but what?” Zhou Wenhai relaxes, asked at a loss: “没闯祸那就好,只不过什么啊？”周文海松了一口气,茫然地问: In one hour in laboratory, Zhou Xing asked a question a moment ago, is an issue, inquired continuously, to answer his issue, the time of continually gasping for breath did not have, to want the short remaining life! 刚才在实验室里的一个多小时里,周兴问完一个问题,又是一个问题,源源不绝地提问,为了回答他的问题,连喘口气的时间都没有,要老命哦！ If Zhou Xing asked related to issue of monolithic integrated circuit development, Liu strong at least can deal with reluctantly, that knowledge afterward, the boy actually asked other electronics domains issues, for example: The electronic communication, the automation, the information engineering, the electric control,..., wait/etc., the issue of electronics domain, bullied the person, that had his, left class so many domains knowledge, moreover knowledge also very solid appearance. 如果周兴问的都是涉及单片机开发的问题,刘强至少能勉强应付,那知到了后来,那小子竟然问起其他电子领域的问题,比如:电子通讯,自动化,信息工程,电气控制,…,等等,电子领域的问题,太欺负人了,那有他这样的,一下学这么多领域的知识,而且知识还很扎实的样子。
