人生的意义靠自己赋予

“我是谁?我从哪里来?我要到哪去?”,常常都在问,却不曾有答案。然而,是什么让我们的每一次呼吸都有意义?可能就是看似触手可及,但却无论怎么伸长手臂也碰不到的梦想吧。人人都有梦想,只是其程度不同,害怕说出口会被他人耻笑,又或许自己的梦想太不切实际,会觉得梦想只配是个梦而已。有勇气说出梦想,并一直在为之努力的人,都值得受到大家的尊重。

李程威,父亲从商,家临马六甲海峡,从小甚至自己都觉得长大后会继承父亲衣钵,当个鱼贩,月休两天,夜夜凌晨2点营业,过着日夜颠倒的生活。直至临近高中毕业,他才意识到自己应该深思未来去向。于是乎,把心一横,远赴两千公里外,留学交大。面对众多专业选项,毅然决然选择航空航天。程威的亲朋戚友如出一口,马来西亚造得出飞机还是火箭?其实,甚至他自己都不知道,这是阳关道或是独木桥,又或者仅是一条死胡同。

但是,他有个梦想,他想改变马来西亚,他想让马来西亚的科学技术水平能在某一方面能因为自己的成就而有些许突破这很难,他清楚。但他更清楚,这就是他赋予自己人生的意义。

 

"Who am I? Where am I from? Where am I going to? " These are the questions that are often asked but hardly get answered. Nevertheless, what makes every breath we take meaningful? It may be a dream which seems to be within reach but can never be achieved no matter how hard you stretch your arms. Everyone has dreams but to different degrees. Some people are afraid that they will be laughed at by others if they say them aloud. Some think their dreams are too unrealistic and they feel like dreams can only be dreams. People who have the courage to state their dreams aloud and have been working hard toward them deserve everyone's respect.

Li Chengwei, whose father is a businessman and whose family is near the Strait of Malacca, once thought he would inherit his father's mantle when he grew up, becoming a fishmonger, who only has two days off every month, starts working at 2 a.m. every day, and lives a life with reversed days and nights. It wasn't until he was about to graduate from high school that he realized he should seriously think about his future. So, he made up his mind and traveled 2,000 kilometers away to study at SJTU. When choosing one from various majors, he decided to choose aerospace. Cheng Wei's relatives and friends all questioned whether Malaysia could build planes and rockets. In fact, even Cheng Wei himself didn't know if it would be a broad road or a narrow bridge, or just a dead end.

However, he has a dream. He wants to make a difference in Malaysia. He hopes that some areas of  Malaysia's science and technology can reach a higher level because of his achievements. He understands that it is hard. But he knows better that this is the meaning he gives to his life.

 

总要有人触碰平凡

本硕六年交大人。前三年在四千多亩校园里,过着十几人的团体生活,社团创办人、四届上马志愿者、交大国际宣传大使、演出舞台的常客、留学生会、……;后三年在一米书桌前,呆在一人一电脑的小房间,CNKI、ENDNOTE、PYTHON、EXCEL、……。想必这类似的经历,很多留学生都感同身受吧。小房间里的孤独、焦虑感不停地让人怀疑自己、问自己,“我到底在干嘛”。日复日、月复月、年复年坐在电脑前,敲着代码、跑着仿真、不断试错、记着根本不知道有没有用的数据。这就是科研吗?李程威说对他而言,是,但也不是。

航空航天领域里包含结构、推进、控制等等,而李程威选择了噪声方向进行深入研究。这其中得从一个机遇开始说起,即遇见了其导师,从事气动噪声研究的马威老师。在与马老师的沟通交流后,程威发现了一个对他而言很是新颖的领域。再深入探索后发现,声源定位技术不仅能用于降噪、故障诊断,还能应用于管道气体泄漏、电力局放等,具有庞大的发展潜力和研究价值。

对他而言这无疑是个冷门且新兴的领域,久而久之程威对参考文献中的作者都倍感亲切,因为钻研这方向的学者并不多。然而在程威的研究中,多数都是在为他人的研究成果进行细化分析,让工程界应用这些技术时能有个参考。如其毕业论文和文章中所做的研究,大部分都是在分析实际操作过程中,各种可控与不可控的变量对定位结果造成的影响分析。其中创新的部分也是在优化后处理算法中的一小个模块。这些研究参加不了比赛,成果也不足以广发高质量文章。而正是因为他亲身实际动手进行过相关测试,发现了其中的难点,所以更清楚有些研究不能没有人去做。有些科研工作就是平凡的,但总要有人去触碰平凡。

 

He spent six years in SJTU to get his bachelor’s and master’s degrees. In the first three years, on the 4,000-acre campus, he lived a collective life. He was the founder of clubs, the volunteer of four years’ Shanghai Marathon competitions, the international publicity ambassador of SJTU, a frequent visitor of performance stages, and a member of the International Student council. For the next three years, he stayed in a small room with only one computer in front of a one-meter desk, dealing with CNKI, ENDNOTE, PYTHON, and EXCEL all day. Presumably many international students have the same experience as him. The loneliness and anxiety in a small room constantly make him doubt themselves and ask himself, "What on earth am I doing?" Day after day, month after month, year after year, sitting in front of the computer, typing code, and running simulations through trials and errors, recording data that he didn't know if there was any use at all. Is this scientific research? Li Chengwei’s answer is yes, and no.

The aerospace field involves structure, propulsion, control, etc., and Li Chengwei chose the direction of noise for in-depth research. This starts with an opportunity, that is, meeting his mentor, Mr. Ma Wei, who has been engaged in aerodynamic noise research. After communicating with Teacher Ma, Cheng Wei discovered a field that was very novel to him. After further exploration, it is found that the sound source positioning technology can not only be used for noise reduction and fault diagnosis but also can be applied to pipeline gas leakage, power partial discharge, etc., which has great development potential and research value.

This is undoubtedly an unpopular and new field for him. And over time Cheng Wei has felt really familiar with the authors in the references since there are not many scholars who have studied in this area. However, most of Cheng Wei's research is to refine the research results of others, so that the engineering community can have a reference when applying these technologies. For example, most of the research done in his graduation thesis and articles are to analyze the impact of various controllable and uncontrollable variables on the positioning results in the actual operation process. The innovative parts count for only a small proportion of the optimization post-processing algorithm. He cannot participate in the competitions with these researches since they are so minor, and the results were not enough to widely disseminate high-quality articles. It is because he personally carried out the relevant tests and experienced the difficulties, he knew better than others that there has to be someone to carry out these tests. Some scientific work is ordinary, but there has to be someone who gets down to the ordinary.

 

只要肯坚持努力,

最坏的结果不过是大器晚成

硕士两年,没有靓丽炫目的履历荣誉,也没有撼天动地的惊世成果。李程威自知天资不足,只有稳扎稳打的一步步摸索。他说,科研路上没有捷径,但凭着远大抱负、家人的支持、导师的指导、伙伴的陪伴、自己的努力坚持,就会义无反顾地继续走下去。李程威认为,科学技术需要创新,以迈向更优的;也需完善,以填补拥有的。然而对于“完善”,他也强调并不是所有的“填补空白”都没有意义和价值。在完善的过程中,能迸发许多想法,甚至帮助创新。同时,他所做的科研工作一直都围绕着工程实际应用,每一步都在朝着自己的梦靠近。他相信,只要肯坚持努力,未来会来,梦想终会成真。

During the two years of his master's degree, he won no dazzling resume honors, nor ground-breaking results. Li Chengwei knew that his experience was insufficient so he had to improve himself step by step, steadily. He said that there were no shortcuts on the road of scientific research, but with great ambitions, the support of his family, the guidance of his mentors, the company of his partners, and his own efforts, he would continue to work hard without hesitation. Li Chengwei believes that for science and technology, innovation is needed to move towards the better; optimization is also needed to make up for current defects. However, speaking of "optimization", he also stressed that not all "filling in the gaps" is meaningless or invaluable. In the process of optimization, many new ideas can burst out and even help innovation. At the same time, his scientific work has always revolved around the practical application of engineering. And every step he takes is getting him closer to his dream. He believes that as long as he is willing to make effort, the future will come and his dreams will come true.
