超高压物理实验技术虚拟仿真实验设计与实现

Design and Implementation of Virtual Simulation Experiment of Ultra-high Pressure Physics Experiment Technology

为解决传统高压物理实验教学中设备投入高、数量不足、实验空间受限等问题,自主开发了超高压物理实验技术虚拟仿真实验。该实验以超硬材料立方氮化硼的合成与分析过程为主线,划分为原料称量及预处理、六面顶压机高温高压合成样品及样品性能测试分析3个实验任务,实验操作允许学生在一定范围内自主设置实验参数、合成条件,通过不断仿真练习,形成对实验工艺流程、仪器设备操作的正确认识和超硬材料合成原理的深度理解,提升学生自主学习、探究问题、解决问题的能力。

In order to solve the problems of high equipment investment,insufficient quantity,and limited experimental space in traditional high-pressure physics experiment teaching,the virtual simulation experiment of ultra-high pressure physics experiment technology was independently developed.The experiment is based on the synthesis and analysis process of superhard material cubic boron nitride.It is divided into three experimental tasks:raw material weighing and pretreatment,high-temperature and high-pressure synthetic sample with six-sided top hydraulic press,and sample performance test and analysis.The experimental operation allows students to independently set experimental parameters and synthesis conditions within a certain range,and through continuous simulation exercises,form a correct understanding of the experimental process,the operation of instruments and equipment,and an in-depth understanding of the principles of superhard material synthesis,so as to enhance students’ability to learn independently,explore problems,and solve problems.
