模拟实验是一种实物实验,但实验中所用的实物并不是真正的研究对象。实验中观察到的现象、测得的数据和结论,要经过推理、想象、换算才能适用于真正的研究对象。物理学所研究的对象,大至宇宙、星系……,小至分子、原子、核子、中微子……;物理变化所用时间,长则超过人类历史,短则远非一瞬间所能形容。物理实验室的大小、实验时间、观察手段、仪器装置都有一定的限制,不可能在实验室内重现所有的物理现象。模拟实验就是把这些过大或过小的研究对象,过长或过短的变化时间,或人的感官无法直接惑知的物理现象变换成实验室
Simulation experiment is a kind of physical experiment, but the physical object used in the experiment is not the real research object. The observed phenomena, measured data, and conclusions in the experiment must be reasoned, imagined, and scaled before they can be applied to real research subjects. The objects studied by physics are as large as the universe, galaxies, ... as small as molecules, atoms, nuclei, neutrinos, etc.; the time taken for physical changes is longer than human history, while the short term is far beyond what can be described in a flash. The physical laboratory’s size, experiment time, observation methods, and instrumentation all have certain limitations and it is impossible to reproduce all physical phenomena in the laboratory. The simulation experiment is to transform these oversized or undersized subjects, too long or too little time for change, or physical phenomena that people’s senses can’t directly understand into a laboratory.
