Yue Liu,Ying Liu,Michael G. B Drew,Wave Mechanics of Microwave Absorption in Films: Multilayered Films, Journal of Electronic Materials, 2024, doi: 10.1007/s11664-024-11370-9
该文是理论研究。
普遍的观点是实验研究比理论研究重要。
理由是理论经常被证明是错误的,但是实验结果不会错。
理论需要被实验证实才能说对。
因此一些人认为只要有实验结果就够了,理论要不要都行。
该文的一个段落针对这个观点做了评论,摘录如下并附中文翻译:
"However, on the other hand, contemporary research is heavily reliant on experimental research and,
as a result, theoretical research is often undervalued until it is verified by experiments.
当代研究严重依赖实验研究,理论研究被严重低估。
现代科学家普遍认为理论需要被实验验证,因此多数人认为理论没有多大意义。
Indeed, our work shows the power of theoretical research in revealing the results behind
experimental data. Without theoretical research, it can be misleading to rely
only on experimental methods.
我们的工作表明理论研究在揭示实验数据背后的新结果方面的力量。
如果没有理论的指导,仅仅依赖实验方法,很难从实验数据中发现应该发现的东西。
例如
从太阳围着地球转的实验观测,很难发现实际是地球围着太阳转。
坐火车,我们会以为大地在向后方运动。
Theoretical research is independent and has its own place in scientific research.
科学研究中,理论研究是独立于实验的研究。
A classic example is that perpetual machine can not be built
since it violates the second law of thermodynamics. It has been proved theoretically
that the absorption peak of film originates from wave cancellation, but for a long time it has been
wrongly believed that it originates from the attenuation power of material along the zig-zag optical path
or material resonance.
例如
因为对热力学理论的肤浅理解,很多人致力于永动机的实验研究。
膜的微波吸收峰是波叠加的结果。
但是长期以来的实验研究完全错了。
膜的微波吸收峰被错误地认为是材料本身的固有谐振频率。
膜的这种微波吸收被错误地认为是微波在光路上被材料的固有吸收能力决定的。

For example, the impedance matching theory has been believed to
be correct based on verification by experimental reports, however, when it has been proved
wrong theoretically, evidence against the theory having poured in from different perspectives.
微波领域的实验研究一直认为阻抗匹配理论已经被实验证明。
但是当阻抗匹配理论被理论研究推翻后,
违背阻抗匹配理论的证据从不同角度涌现, 进而推翻了原来的实验论证。
只有地心理论被日心理论推翻后,
才认识到原来支持地心理论的实验证据实际上都支持日心理论。
This result shows the importance of theoretical research, that is, without the guidance of
correct theoretical insight, it is difficult to identify features contained in published experimental data
that have not identified before.
这个结果表明理论的重要。没有正确的理论指导,很难从实验数据中发现以前没有认识到的问题。
Theoretical research is usually enabling people to reveal insights from common experimental phenomena from which these new points have not been recognized before.
理论帮助研究人员从实验数据中发现以前没有被认识的自然界的本质特征。"
=====================
推翻现行微波吸收理论是系列工作,其结果的发表一寸一寸地取得进展
实验不是科学,一项实验不能因为被科学项目基金资助了就变成了科学研究
科学更是提高实验技术、堆积实验现象,还更是提升理论认知,建立学科理论
化学不是实验科学、物理不是实验科学、正确的理论才是检验科学的唯一标准
