是對所學(xué)知識的一次大總結(jié),在設(shè)計之前,收集有關(guān)設(shè)計課題研究方面的資料、文獻(xiàn)是最為重要的。在設(shè)計工作開始時,只有對課題研究的內(nèi)容充分地了解,才會 有設(shè)計目的和方向;所以收集、查閱有關(guān)文獻(xiàn)資料是必要的。 收集有關(guān)資料的時候,不僅使我對包裝封口機械發(fā)展現(xiàn)狀及發(fā)展趨勢、設(shè)計的具體思路等有了更多,更全面地了解;而且收集到了許多有關(guān)與封口機械相關(guān)、相似的設(shè)計,查找各種有關(guān)封口機設(shè)計的各種方法和主要用途;通過查閱資料和文獻(xiàn)能夠?qū)⒄n堂上所學(xué)習(xí)到的理論知識,與實際生產(chǎn)當(dāng)中的實例相結(jié)合去更好地完成設(shè)計任務(wù);并且使我在課程設(shè)計上有了更多的設(shè)計思路,也有了更多的考慮空間,同時也使我在設(shè)計的過程中能夠從多方面地去考慮問題。 畢業(yè)設(shè)計的目的主要是培養(yǎng)我們運用所學(xué)理論知識和專業(yè) 知識來分析和解決機構(gòu)設(shè)計中所出現(xiàn)的一系列問題。本次的設(shè)計是幾年來學(xué)習(xí)過程中涵蓋面最廣的一次設(shè)計,它不僅體現(xiàn)了我們對機構(gòu)的設(shè)計,更重要的是對我們幾年來所學(xué)知識應(yīng)用到了實踐,使我明白了在今后設(shè)計過程中的一般步驟和方法。 通過本次設(shè)計,我學(xué)會了如何對進(jìn)行合理分析。同時,在本次設(shè)計過程中同時了解了如何編寫技術(shù)文件,正確使用設(shè)計手冊。更培養(yǎng)了我們嚴(yán)肅認(rèn)真、一絲不茍和實事求是的工作態(tài)度,從而實現(xiàn)了從一名學(xué)生到工程技術(shù)人員的過渡。 總之,本次設(shè)計讓我 受益匪淺 ,各方面的能力都有了提高。但由于本人設(shè)計能力有限,再加上實踐能力 和經(jīng)驗不足,設(shè)計中難免有不足之處。但通過設(shè)計使我各方面的能力都得到了很大提高,為今后工作和學(xué)習(xí)奠定了堅實的基礎(chǔ),我認(rèn)為這才是最重要的。 因水平有限,錯誤難免,懇請各位老師批評指正。 齊齊哈爾大學(xué)畢業(yè)設(shè)計(論文) 19 參考文獻(xiàn) [1] Nitaigour P.

Among Chinese myopia patients,30million are severe patients, according to ZhouThe prevalence of myopia among high school and college students is more than 70 percent,and the situation is continuously worsening, he Zhu, director with the China Youth Development Service Center, said long hours ofstudy, lack of exercise, especially outdoor activities, and attachment to electronic screen aresome of the top reasons behind the widespread myopia problems, and the increase ofyounger patients, although China has made great progress in improving the hardwarefacilities and lighting conditions in said he hopes the survey will alert people on the threatening situation, and also helpmedical experts to better guideline parents and children39。s behaviors to care for eyes, basedon the timely and factual statistics the survey series of followup events will also be held in six cities, including Jinan in Shandongprovince, and Changsha in Hunan province, to educate people on how to care for eyes afterthe survey started. More and more Chinese are jogging to get and stay fit. Most joggers will run alone, but some will jog with friends or even coaches. The Beijing Olympic Forest Park is one of the most popular spots. It is packed with runners in the afternoon, usually after work, and at weekends. Jogging after a whole day39。s work can be a way to unwind. It is true for He Wenjun, whose workplace is right near the forest park. She discovered her athletic aptitude at the age of seven, when she began playing tennis. Then she turned to jogging, and she has persevered with it for 10 years. I e to jog almost every day after work, whenever I have time. I think jogging is good for my health. And for me, a girl, it helps me to achieve to eternal goal, to keep slim, He said. He says she prefers jogging alone, so she can focus better. She loves jogging, even during Beijing39。s smoggy days. If the smog is severe, I39。ll hold off jogging for a while. But if I really want to get away from work, I39。ll wear a mask, or just ignore the smog and go on jogging, she said. For those who are not so athletic, jogging also has its attractions. Wu Houbi
