In the traditional Young's double-slit interference experiment, the human eye is often used toobserve the fringes to measurethe fringe spacing. However,this method is prone to causing signilficant errorsdue to factors such as visual fatigue. Therefore,a measurement platform for Young's double-slit interferenceexperiment was constructed based on MATLAB to accurately measure the fringe spacing and automaticallycalculate the wavelength value of the laser used in the experiment. After converting the original image into agrayscale image,the image is preprocessed, anisotropic diffusion filtering, adaptive threshold processing andpseudo-color image mapping operations are carried out. The spacing of the processed stripes is measured,andthe laser wavelength is calculated in combination with the experimental parameters. The results show that theaverage absolute error of the laser standard wavelength in the experiment is -0.30 nm,and the average relativeerror is only 0. 047 2%,which is much smaller than the 19.91 nm and 3.135 4% observed by the human eye.The above indicates that the constructed measurement platform can accurately measure the wavelength value ofthe laser used in the experiment with a nanometer-level error,which has certain practical value.

The aceurate processing of experimental data is essential in physics. However,experimentallymeasured data are often discrete and limited, presenting challenges in reconstructing the inherent continuity ofphysical processes. Consequently, investigating the applicability of various interpolation methods inreconstructing continuous curves across diverse physical scenarios emerges as a pivotal issue.In this study,fourinterpolation methods-linear,shape-preserving piecewise cubic,cubic Hermite,and cubic spline-are appliedto experimental data from three types of experiments:forced vibration, Franck-Hertz,and simple pendulum.Theresults show that shape-preserving piecewise cubic interpolation works best for forced vibration data, cubicsplineinterpolation is more suitable for the Franck-Hertz experiment,while the simple pendulum caseunderscores the limitations of interpolation methods under conditions of data sparsity and high noise levels.Collectively,'these findings support the central conclusion of this study: no single interpolation method isuniversally optimal,and the choice of an appropriate method depends critically on the intrinsic nature of thephysical experiment and the characteristics of the data obtained.

This research oot only provides new ideas andmethods for in-depth understanding of the law of energy conversion efficieney,but also has certain applicationpotential in green energy-related fields such as kinetic energy recovery and new-type power generationequipment.

This paper investigates the real-time change in electrical conductivity of Jaser-induced graphene(LIG) during the deformation process. By designing and constructing an experimental setup,high-precisionmeasurement (with a relative error of less than 2%) and visual display of the resistance change of LIG underdifferent bending deformations were achieved. The experimental results show that the resistance of LIG changessignificantly with the increase of deforation degree,exhibiting excellent linearity and repeatability.Based onthis characteristic,the application of LIG in the feld of human-computer interaction was developed,realizingthe real -time operation of controlling an intelligent car through finger joint movements. This study provides newideas and methods for the performance research and practical application of flexible conductive materials.

 In order to solve the problems of complicated procedures and expensive turtable equipment in thetraditional high-precision calibration of the Micro Inertial Measurement Unit ( MI MU),a novel turntable-freeMI MU error calibration algorithm based on the genetic method is proposed.In this algorithm,the wavelet noisereduction method is used to preprocess the random noise of the MI MU measurements,the muli-position rotationscheme is designed to excite the Ml MU errors,and then the M MU error function is constructed,which is usedas the objective function in the genetic algorithm.Based on this,the MI MU error parameters are effectivelyidentified by searching and optimizing the objective function.Compared with traditional high-precision turtablecalibration algorithms,the proposed algorithm does not require expensive test equipment and the calibrationprocess is much simpler. Simulation results show that the proposed algorithm is both effective and feasible inachieving high-precision error calibration for the MIMU. This study provides a referenee for the application andresearch of low-cost inertial navigation systems while also fostering students' ability to conduct independentscientifie research.
