What titles are specific? In preparing the title of a paper, a general
and abstract title should be avoided. For example, such a title as Computer Retrieval will be regarded as too general and global, vague and empty, telling the reader nothing specific. It would be better to change the title into something like Computer Retrieval on Literature of Physics, or Computer Retrieval on International Conference Information, according to the content of the paper.

关于科技的大学英语作文
关于科技的大学英语作文科技是一把双刃剑，但是我们的大学生活却可以引导它走向正确的方向。
下面是店铺给大家整理的关于科技的大学英语作文，供大家参阅!关于科技的大学英语作文：What Does Technology Do to TraditionWhat Does Technology Do to Tradition?"Technology or tradition", a sc-called contradiction, didn't become a popular topic until recently. When the tradition of "men plow and women weave" is broken up by the influx of advanced agricultural tools, skyscrapers stand firm where there used to be the homes of intimate neighbors, and handwork is replaced by machines, people can't help wondering, "What's wrong with us?" Apprehensions abound among scholars. Is it true that too much of our attention and energy have been diverted to the technology and the traditional culture will reduce to a desolation?"Technology or tradition" is a question causing increasingted to the technology and the traditional culture will reduce to a desolation?"Technology or tradition" is a question causing increasing controversy nowadays, but in my opinion, it is not a choice that we can make. It's true that technology will affect our traditionalculture but the former can and should never undermine the latWith a history of thousands of years, traditional culture is not so fragile as we thought it might be. It is rooted in our minds, influencing our every deed. We are strictly governed by the tradition passing from generation to generation. Technologyfrom which we benefit much in our daily life gives us conveniences and may change our lifestyle in some parts as well. Thus some tradition may be affected. Farmers lose their opportunity of plowing and, with the appearance of grain drill, their sowing skills are no longer needed.., but we should be cautious that technology also plays the role of selector here, singling the long lasting vital values while eliminating the others which account for only a small percentage. Permanent spirits such as "teamwork"and "love for others" still stand firm in all societies and hold its dominance. Moreover, tradition doesn't always stay unchanged.Its development is somewhat a process of evolution. So why should our technological world be thought of as a threat rather than a system of selection in harmony with the human evolution?In addition, what technology brings to our traditional world are changes, the gradual changes, rather than radical revolution that gives rise to chaos and panics. With new technology emerging, we're allowed to have enough time to look back and guard against its invasion into the core of our traditional culture to strive for a balance.Looked at from another angle, new technological development also contributes to the enrichment and perfection of our traditional culture. It adds new contents to our culture and opens a new vista for it. The modern communications technology prorides more opportunities of cultural exchanges. And the combination of technology and human culture has become an irreversible trend. Do you remember the advertisement, "Technology is determined by men. "That's a perfect example.In conclusion, while changing traditional cultures slightly,technology benefits it as well. They can be balanced ifhandled properly.简评科技与传统之争是当前的一个热门话题。

Title: Finite-Difference Time-Domain Algorithm for Solving Maxwell’s Equations in Rotationally Symmetric Geometries
Abstract—In this paper, an efficient finite-difference time-domain algorithm(FDTD) is presented for solving Maxwell’s equations with rotationally symmetric geometries. The azimuthal(方位角) symmetry enables us to employ a two-dimensional (2-D) difference lattice by projecting the threedimensional (3-D) Yee-cell in cylindrical coordinates(r,φ,z) onto the r-z plane.

四六级英语科技作文模板The Influence of Technology on People's Lives。
In today's society, technology has become an integral part of our daily lives. It has significantly impacted how we communicate, work, and live. The influence of technology on people's lives is undeniable, and it has both positive and negative effects.First and foremost, technology has revolutionized the way we communicate. With the advent of smartphones, social media, and messaging apps, people can now easily connect with others regardless of their location. This has made communication more convenient and efficient, allowing people to stay in touch with friends and family, as well as collaborate with colleagues and business partners. Additionally, technology has also facilitated the sharing of information and ideas, enabling people to access news, knowledge, and resources from around the world.Furthermore, technology has transformed the way we work. The rise of automation, artificial intelligence, and digital tools has led to increased productivity and efficiency in various industries. Tasks that were once time-consuming and labor-intensive can now be completed in a fraction of the time, thanks to technological advancements. Moreover, remote work has become more prevalent, allowing people to work from home or any location with an internet connection. This has provided greater flexibility and work-life balance for many individuals.In addition to communication and work, technology has also had a profound impact on how we live our daily lives. From smart homes and wearable devices to online shopping and entertainment streaming, technology has made our lives more convenient and enjoyable. We can now control our home appliances with a simple voice command, track our health and fitness goals with wearable devices, and access a vast array of entertainment options at our fingertips. These advancements have undoubtedly improved the quality of life for many people.However, despite the numerous benefits of technology, there are also drawbacks that cannot be ignored. One of the most significant concerns is the impact of technology on mental and physical health. Excessive screen time, sedentary behavior, and the constant connectivity to digital devices have been linked to a range of health issues, including eye strain, sleep disturbances, and social isolation. Moreover, the rapid pace of technological innovation has led to concerns about job displacement and the potential loss of human skills and expertise.Furthermore, the reliance on technology has raised privacy and security concerns. The collection and utilization of personal data by tech companies and the risk of cyber-attacks and data breaches have become major issues in the digital age. Additionally, the spread of misinformation and the proliferation of online scams and fraud have eroded trust in the digital ecosystem.In conclusion, technology has had a profound influence on people's lives, shaping the way we communicate, work, and live. While it has brought about numerous benefits and advancements, it also comes with challenges and potential risks. As we continue to embrace and integrate technology into our daily lives, it is essential to be mindful of its impact and strive for a balanced and responsible use of technology. Only by doing so can we fully harness the potential of technology while mitigating its negative effects.。
