【正文】 的步伐，讓我總是為了解決一 個小問題而花費很長的時間。最后還要查閱其他的書籍才能找出解決的辦法。并且我在做設(shè)計的過程中發(fā)現(xiàn)有很多東西，我都還不知道。其實在計算設(shè)計的時候，基礎(chǔ)是一個不可缺少的知識，但是往往一些核心的高層次的東西更是不可缺少。 其次，多和同學(xué)討論。我們在做課程設(shè)計的工程中要不停的討論問題，這樣，我們可以盡可能的統(tǒng)一思想，這樣就不會使自己在做的過程中沒有方向，并且這樣也是為了方便最后程序和在一起。討論不僅是一些思想的問題，他還可以深入的討論一些技術(shù)上的問題，這樣可以使自己的人處理問題要快一些。 最后，多改變自己設(shè)計的方法。 在設(shè)計的過程中最好要不停的改善自己解決問題的方法，這樣可以方便自己解決問題。 通過本次對一個 VM 雙閉環(huán)不可逆直流調(diào)速系統(tǒng)課程設(shè)計使我對電力電子技術(shù)電力拖動自動控制系統(tǒng)有了進(jìn)一步的了解與認(rèn)識。對所學(xué)內(nèi)容有了更深刻的印象，并且進(jìn)一步認(rèn)識到工程設(shè)計時與實際相聯(lián)系的重要性，比如在計算元件參數(shù)時計算出來的值往往與實際生產(chǎn)參數(shù)不符，這就需要根據(jù)實際情況對參數(shù)進(jìn)行取舍。另外，做設(shè)計時信息十分重要，我運用文件檢索工具查閱了大量的相關(guān)資料，這對設(shè)計大有益處。本次課程設(shè)計為對我將來的畢業(yè)設(shè)計和工作需要打下了扎實的基礎(chǔ)。 25 參考文獻(xiàn) [1]陳伯時 . 電力拖動自動控制系統(tǒng) [M].北京：機械工業(yè)出版社 .2021 年 . 20— 190.

You may need to make a claim to an employment tribunal if: ? you don39。t agree with the disciplinary action your employer has taken against you ? your employer dismisses you and you think that you have been dismissed unfairly. For more information about dismissal and unfair dismissal, see Dismissal. You can make a claim to an employment tribunal, even if you haven39。t appealed against the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept it. If you are worried about how the time limits apply to you, take advice from one of the anisations listed under Further help. Employment tribunals are less formal than some other courts, but it is still a legal process and you will need to give evidence under an oath or affirmation. Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the anisations listed under Further help. If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。t charge you more than 35% of your pensation if you win the case. If you are thinking about signing up for a damagesbased agreement, you should make sure you39。re clear about the terms of the agreement. It might be best to get advice from an experienced adviser, for example, at a Citizens Advice Bureau. To find your nearest CAB, including those that give advice by , click on nearest CAB.

I am going to be at the match tomorrow and I have asked to meet Yaya Toure, he told BBC Sport. For me it39。s about how he felt and I would like to speak to him first to find out what his experience was. Uefa has opened disciplinary proceedings against CSKA for the racist behaviour of their fans during City39。s 21 win. Michel Platini, president of European football39。s governing body, has also ordered an immediate investigation into the referee39。s actions. 28 CSKA said they were surprised and disappointed by Toure39。s plaint. In a statement the Russian side added: We found no racist insults from fans of CSKA. Age has reached the end of the beginning of a word.
