ofc是什么意思？
“ofc”可能是是office的缩写，意思是：办公室；可能是oxygen-free copper的缩写，意思是：无氧铜；也可能是Operational Flight Control的缩写，意思是作战飞行控制。办公室读音bàngōngshì英文名Office： 处理一种特定事务的地方或提供服务的地方。是提供工作办公的场所，不同类型的企业，办公场所有所不同，由办公设备，办公人员及其它辅助设备组成，在办公室适合放些对人和工作氛围有帮助的东西，如花，画等。 办公室，还可以指一种机构，如区委办公室、区政府办公室、党校办公室等，它是一个单位对外的窗口，对内协助领导工作的机关。名词解释：西方古代的办公室通常是宫殿或大型庙宇中的一部份。通常是一间存放有大量卷轴的房间，并有抄写员在其中进行工作。对一些考古学家和大众媒体而言，这些房间有时也被称为“图书馆”（Libraries），因为这个场所通常与记载有文学作品的卷轴有关。事实上，除了诗歌或虚构的文学作品之外，自从各种记录、合约、命令、公告等内容都被记载于卷轴上起，这些存放卷轴的房间就有了现代“办公室”的定义。

OFC是无氧铜（oxygen-free copper）的意思。根据含氧量和杂质含量，无氧铜又分为一号和二号无氧铜。一号无氧铜纯度达到99.97%，氧含量不大于0.003%，杂质总含量不大于0.03%；二号无氧铜纯度达到99.95%，氧含量不大于0.005%，杂质总含量不大于0.05%。无氧铜无氢脆现象，导电率高，加工性能和焊接性能、耐蚀性能和低温性能均好。各国对于含氧量的标准也不完全相同，存在一定的差异。OFC（无氧铜）：纯度为99.995% 的金属铜。一般用于音响器材、真空电子器件、电缆等电工电子应用之中。其中无氧铜中又有 LC-OFC（线形结晶无氧铜或结晶无氧铜）：纯度在99.995%以上和OCC（单晶无氧铜）：纯度最高，在99.996%以上，又分为PC-OCC和UP-OCC 等。铜具有高的电导率和热导率、良好的可焊性、优良的塑性和延展性、极好的冷加工性能且无磁性，而弥散无氧铜又克服了退火后屈服强度较低和高温下抗蠕变差的缺点，具有高温、高强度和高热导率的特性，受到电子材料专家的高度重视。铜及其合金已在电子工业中得到广泛应用，在真空电子器件中，无氧铜已居该领域中七大结构材料中用量之首。含氧量是无氧铜最重要的性能之一，由于氧和铜固熔量很小，因而无氧铜中之氧，实际是以Cu2O形式而存在。在高温下，氢以很大的速度在铜中扩散，遇到Cu2O并将其还原，产生大量的水蒸气。水蒸气的数量比例于铜的含氧量。例如，0.01%含氧量的铜，退火后，在100g铜中会形成14cm3的水蒸气，该水蒸气不能经致密铜而扩散，因而在存在Cu2O的地方，会产生几千兆帕压力，从而使铜破坏并产生脆裂和失去真空致密。因而，对氧含量必须进行严格限制。以上内容参考：百度百科——无氧铜
当外国人对你说ofc是什么意思
"OFC"是光电光通讯及其相关领域的顶级会议，也是英语"Oxygen Free Copper"的缩写，意为“无氧铜”。在欧美俚语中、论坛上和即时聊天软件中ofc.,就是 of course的缩写，意思是当然，肯定的。OFC也指“眼窝前额皮质”，即orbitofrontal cortex。【摘要】

外国人说OFC是什么意思
OFC意思是无氧铜。无氧铜（oxygen-free copper），不含氧也不含任何脱氧剂残留物的纯铜。但实际上还是含有非常微量氧和一些杂质。按标准规定，氧的含量不大于0.003%，杂质总含量不大于0.05%，铜的纯度大于99.95%。无氧铜制品主要用于电子工业。常制成无氧铜板、无氧铜带、无氧铜线等铜材。无氧铜的熔炼：严格区分，无氧铜应分为普通无氧铜和高纯无氧铜。普通无氧铜可以在工频有铁心感应电炉中进行熔炼，高纯无氧铜的熔炼则应该在真空感应电炉中进行。采用半连续铸造方式时，熔体在熔炼炉和保温炉内的精炼过程可以不受时间约束。连续铸造则不同，铜液的质量不仅依赖于熔炼炉和保温炉的精炼质量，更重要的是还需要依赖于整个系统和全过程的稳定性。
什么是无氧铜？
无氧铜是指不含氧也不含任何脱氧剂残留物的纯铜。实际上还是含有非常微量氧和一些杂质。按标准规定，氧的含量不大于0.03％，杂质总含量不大于0.05％，铜的纯度大于99.95％。 根据含氧量和杂质含量，无氧铜又分为一号和二号无氧铜。一号无氧铜纯度达到99.97％，氧含量不大于0.003％，杂质总含量不大于0.03％；二号无氧铜纯度达到99.95％，氧含量不大于0.003％，杂质总含量不大于0.05％。无氧铜无氢脆现象，导电率高，加工性能和焊接性能、耐蚀性能和低温性能均好。 OFC（无氧铜）：纯度为99.995% 的金属铜。

论文摘要如何翻译成英文
论文摘要翻译成英文可以借助一些翻译软件，把英语的句子都输入进去就可以翻译了，但这样做的翻译不是很准确，建议找翻译网站。由于中国人的思维方式与西方英语国家的人有着明显的不同，例如句子结构上往往存在前后次序的差别，表达方式上有各自最恰当的词语，并且与中文不一一对应。国内许多学术论文的英文摘要是根据中文摘要直译成英文的，由于没有考虑适合英语表达的思维方式，这样的英文摘要往往使外国人费解。所以，在翻译摘要时一定要考虑到中英文表达习惯上的差异，通过意译将原文主要内容按西方人的思维习惯完整地表达出来，不要逐字逐句、一一对应地生硬翻译。建议选择国际科学编辑，他们在欧洲、北美和澳大利亚等英语母语国家已经拥有的一个值得信赖并高质量的编辑队伍，国际科学编辑可以为全世界的科学家提供英语母语化润色服务。公司所有的科学编辑都具有博士学历，拥有丰富的科学研究经验及优秀的英语语言技能。20几年来，国际科学编辑不但为科学家提供一对一的语言润色服务，而且与全球知名的出版公司有长期的合作关系，为稿件提供编辑校对服务。
英语翻译
第一段翻译：Exhibition letter Ann, busy to disturb you is really embarrassed. Now, I think I should be time to write a letter to you, I just know you hate me so much,。but please allow to be my last audience? Because there is a lot that I want to tell you through this letter. Thanks. These years, lost your contact but also lost our friendship, my deep regret.Unfortunately, life has no regret! If I can help. Good friends should help each other, isn't they?剩下的翻译：Maybe you don't know, I have been missing you, not blame you, blame me for cowardice and escape. After high school, the family asked me to "official" (superstition). I did not from, so I hid in a classmate's home, at that time。 now think is really ridiculous, obviously very want to know how your college entrance examination, but just do not have the courage to call you, why? Is irritable? Or are timid? Maybe all, so I asked him to inquire about you (call you)。and I knew it harassed you. It may hurt your heart and live up to her expectations. But I am not like that Like it? I hope to take this opportunity to express my apology to you and say sorry to you! I know some things are useless to say sorry, but I still beg for your forgiveness。hope you can accept my late confession, hope the past let him past. Perhaps you have forgotten, perhaps I also do not need to mention again。and perhaps at the beginning is redundant.and then later, gradually there is no news of you. I also have no way, because at that time I was really chaotic, my world became a mess。 my mood was bad to the extreme, I don't want to be tired to you, really! . (Actually, I have asked someone to go to Dongxi to find you。 I know your home is not in Dongxi. ) 。In my freshman year, I dropped out because of my family distress. After that time, I have been living while working and learning, and at that time。Fan Zhengli gave me a great help. The pressure of study and busy work make my daily life full and nervous, but my thoughts for you have never subsided one day. Over the years, I felt like an ostrich with my head buried in a sandbag,。thinking that I could forget all my troubles and missing。but I found that I was wrong, my troubles can be briefly forgotten, and the missing is beheaded in any case. Whenever it is quiet in the dead of night , I always think of all your dribs and drabs。 I always forget your gentle and considerate voice, your beauty, show off the wisdom. Whenever I think of these, I will feel that I am happy, the day's fatigue will also disappear. You have ever know every day after a busy day, with sweet miss sleep, what comfortable ah.

Just be me The years have been wishful thinking and sentimental. People always have to learn to grow up, feelings. Ha ha, so say up, it is as if you gave me a lesson oh? People laugh at me silly, maybe it is, perhaps the feelings really shouldn't see so heavy. Some time ago was originally wanted to make you happy。 (in fact, this is a friend of my search idea, ah... a wrong again wrong. )。 Really disrespect for you, sorry. Ah.... maybe this is a good ending, thank you. People laughed at me silly, maybe it was. Fool, but what? The day still goes on. Right, right? Haha.... Are you doing right now? Your one Are you sister and brother? How about the aunt? Or will you call it so? It feels like you are a bit like an aunt right now. Uncle's eyes are like you, so crazy! Mother and uncle is so happy! Ha ha! After writing these words, feel the mood really relaxed a lot。the original no worry alive is so easy, everything let go, with the encounter! Let everything with the wind! Finally sincerely wish you, wish you smooth work,。wish you find life really love you good partner, wish aunt smile, also wish your family happiness!
