对验证相对论中动量和动能关系的经典实验重新做了实验研究,发现改变磁场强度后该实验的结果并不符合相对论预言的动量和动能关系。根据实验结果,指出了狭义相对论的运动方程中,物体运动时受力(理论值)不变假定是错误的,并提出物体的受力(理论值)应随着运动速度的增加而减小。通过实验,还发现原来实验中对能量的定标偏高。

In an operation mode of atomic force microscopy that uses a higher eigenmode to determine the physical properties of material surface, the ratio between the eigenfrequency of a higher flexural eigenmode and that of the first flexural eigenmode was identified as an important parameter that affects the sensitivity and accessibility. Structure features such as cut-out are often used to tune the ratio of eigenfrequencies and to enhance the performance. However, there lacks a systematic and automatic method for tailoring the ratio. In order to deal with this issue, a shape and topology optimization problem is formulated, where the ratio between two eigenfrequencies is defined as a constraint and the area of the cantilever is maximized. The optimization problem is solved via the level set based method.
