“…Analytical methods to determine isotopic ratio are mostly mass spectrometry and nuclear analytical techniques (as Particle Induced Gamma ray Emission spectroscopy [7], Charged Particle Activation Analysis [8] or Neutron Activation Analysis [9]). The use of simplest instruments, as ICP-OES or AAS, could be considered since a significant isotopic shift in atomic emission or absorption lines has been shown.…”

Due to the low atomic mass of boron, its different isotopes (B-10 and B-11) leads to a measurable impact on vibrational spectra. Indeed, a shift in the asymmetric stretching of the dissolved species has been found using attenuated total reflectance infrared spectroscopy, and those of acid species is higher than those of the borate ion (41 cm -1 vs. 20 cm -1 , respectively).A calibration from pure B-10 to pure B-11 boric acid has been performed, leading to an accuracy higher than 0.5% on the B-10 percentage of 0.1 M solution of mixtures of the two isotopes. Article Highlights-The isotope of boron has an impact on the infrared spectra of solutions -A difference of 14 cm -1 has been found using attenuated total reflectance infrared spectroscopy -The isotopic ratio of boron in boric acid can be measured after a calibration step

“…Aquino G preliminarily explored the teaching of the moving part of charged particles in an electric field, it involves the related motion state of charged particles in the electric field, classifies the research objects, solves problems with the help of mechanics knowledge, and expounds the use of electric field control to change the motion state of charged particles [8].Borah B K tried to use the idea of motion synthesis and decomposition through the real college entrance examination questions and their original questions, in order to deal with the complex curved motion of charged particles in the electromagnetic field, it provides some solutions for related problems [9]. Ikebe Y found that the electromagnetic field knowledge is distributed in the important test sites of the college entrance examination over the years, there is a more important position, among which the relevant concepts of electromagnetic field and the kinetic energy theorem, Newton's law of motion, momentum and other mechanics and electricity related knowledge are often skillfully combined in the comprehensive examination questions of Ulidian, and tend to apply relevant mathematical tools to solve physical problems [10]. Based on the current research, the author aims to explore the motion state of charged particles in a uniform electromagnetic field based on Maxwell's equation.…”

We study the motion states of charged particles in a homogeneous electromagnetic field based on the Maxwell equations. The authors propose the charged particle properties analysis based on the Maxwell equation and electromagnetic field, first explain the Maxwell equation and electromagnetic field properties analysis, and then analyze the charged particles in the composite field (electric and magnetic field coexistence). List the important knowledge points about the motion of charged particles in an electric field, and determine the center of the circle where the charged particles move in a circular motion, simulate the motion of charged particles in a uniform orthogonal electromagnetic field, if at, the trajectory of the charged particle is a short-amplitude cycloid, if, the trajectory of the charged particle is a long cycloid, if. The realization of simulation is mainly based on theory to obtain phenomena, although it has extensive practical significance for confirmatory experiments, when inspiring and guiding students to carry out inquiry learning, physics teachers should still organically combine simulation experiments with traditional experimental teaching, teacher explanations, and student experiments in teaching design and teaching implementation, in order to cultivate students' independent inquiry ability and experimental innovation ability.
