In recent years, with the rapid development of science and technology, the application of SCM is unceasingly thorough. In real-time detection and automatic control of microcomputer application system, its often as a core component to use. But only the microcontroller knowledge is not enough, should be based on the hardware structure, perfect soft combination. Most current universities have established the microcontroller laboratory, basically equipped with experiment box and other hardware simulation equipment. But experiment box hardware circuit fixed, experiment content more difficult change, is hard to adapt to the rapid development of single chip microcomputer and cultivate students' SCM development ability, innovation ability. Using the Proteus software simulation technology, can to a certain extent make up for the shortage, build a virtual experimental platform, can achieve more practice, provide students to learn to disciplinary construction of conditions, has a positive meaning. In view of this, this article based on the single-chip microcomputer simulation environment, Proteus MICOCHIP company by the PIC microcontroller as the main control chip series with data storage units, combined with peripheral infrared sensor, LCD display, temperature sensing, dc motors, heating DianLuSi, alarm equipment, written in C control program main control chip design combines a automatic temperature monitoring and artificially infrared temperature adjustment is an organic whole, have alarm function of temperature control system. This design fully exert Proteus characteristics, reduce the cost and enhance practicability, benefit in university promotion.

In recent years, with the rapid development of science and technology, the application of single chip is accepted broadly in real-time detection and automatic control of microcomputer. Although it’s often act as the core component of single chip system, it is not enough only with the knowledge of single chip. Engineers also need to think about the structure of the hardware to perfect the most higher education institutions have built single chip laboratory, equipped with experiment box and other hardware simulation equipment. But the circuitry of the experiment box is fixed and the experiment steps are hard to be changed. It is not fit the trend of rapid development speed of single chip technology. It is also unsuited to develop students’ abilities and creativities. With the introduction of the Proteus software simulation technology, it can be solved at a certain extent. We could design more experiment steps and help students completing their self-study with the simulation experimental platform. It is a positive technology for system construction. Based on the information above, the author design a temperature alarm system with functions of automatic temperature monitoring and artificially infrared temperature adjustment. This system is created based on the single-chip microcomputer simulation environment, using the PIC single chip of MICOCHIP ltd as the main control chip, combined with peripheral infrared sensor, LCD display, temperature sensing, dc motors, heating electric stove wire and alarm equipment. The control system of main chip and main program was written in C design has the advantages of reducing cost and increase practicability. It is could be adopted by most higher education institutions.

“单片机”是我们国人的称呼，即single chip microcomputer (SCM)，但国际上的说法应该是Micro Control Unit（MCU），即微控制单元。
单片机英文single-chip computer。
重点词汇：single
adj. 单一的，单个的；单身的，未婚的；各自的，分别的；单人的，单人用的；<英>（票）单程的；统一的；由一个部分构成的；（花）单瓣的；唯一的；（酒的）一份
n. 单曲唱片；（板球中的）一分打，（棒球中的）一垒打；单身者，未婚者；<英> 单程票；（旅馆等的）单人房间；单打（比赛）；<美，非正式> 一元纸币；（鸣钟术）不同次序鸣钟法；<美>（影剧院的）一张票，一个座位；一份酒
v. 挑选，选出；（棒球）击出一垒打；对（幼苗，幼树）进行间苗；将（铁轨）变成单线；以一垒打使（跑垒）得分
短语
single room 单人房 ; 单人间
A Single Man 单身男人 ; 单身男子 ; 单身汉
single market 统一市场 ; 单一市场
词语辨析
single, virgin, maiden
这组词都有“未婚者，孤身一人”的意思，其区别是：
single 指尚未结婚的人，但更多指终生不结婚的人。
virgin 通常指未婚者，贞洁未被玷污的人，或指婚烟关系尚未完成者。
maiden 与virgin含义相近，但更着重年轻与未婚，或未曾发生过任何两性关系。
发表英文论文当然是先写中文再翻译，直接用英文写难度比较大，毕竟要先写草稿才可以写文章，所以，先写中文再翻译。
可以啊，毕竟用中文的思路来写论文得更清晰些。
如果你想真正写出一篇高水平的文章，最终必须要直接用英文写文章。需要培养英文思维。
本科论文一般答辩结束后，很少会有修改的。学校复查的几率不是很大。很多人用于查重的论文和答辩的论文都不一样呢。（但是一经发现，学校会严肃处理）但如果是硕士研究生论文，建议还是根据导师意见再重新修改装订。身边有好多学长学姐们都是找北京译顶科技做的，听说也做的很不错
