用Geant4工具包验证Bethe-Bloch公式
Verification of Bethe-Bloch formula using Geant4 toolkit
摘要：
理解物理世界是一个不断尝试和错误的过程。这需要理论背景和工具来发现理论的准确性。粒子在物质中运动，它们的能量损失就是这样一个过程。测试能量损失需要开发一种能够使用数据模拟和测试理论预测的工具。出于这个原因，研究人员开发了一个基于蒙特卡罗的模拟工具包，Geant 4项目。一个多用途的工具包，探索粒子碰撞和能量损失的性质。Geant 4用于需要粒子相互作用的领域，从高能物理到医学物理和空间物理研究。其物理部分提供各种模拟包和工具来研究所涉及的过程。利用电磁场软件包对Hans Bethe提出的带电粒子的Bethe-Bloch能量损失公式进行了验证，并分析了其有效性。
英文摘要：
Understanding the physical world is a continuous process of trial and error. It requires theoretical background and tools to find out the theory's accuracy. Particles motion through matter, and their energy loss is one such process. Testing the energy loss requires the development of a tool capable of simulating and testing theoretical predictions using data. For this very reason, researchers developed a Monte-Carlo based simulation toolkit, the Geant4 project. A multi-purpose toolkit to explore the nature of collisions and energy loss of particles. Uses of Geant4 are in fields where particle interaction is required, ranging from high energy physics to medical physics and space physics research. Its physics component offers various simulations packages and tools to study the processes involved. The study uses the electromagnetic package to verify the Bethe-Bloch energy loss formula for charged particles developed mainly by Hans Bethe and analyse the extent of its validity.
