Abstract：
The paper presents a case study of the data analysis in the CDHS scattering experiment of particle physics performed in 1983. The case study compares the function of computer simulation in the data analysis with recent philosophical work on the role of simulations in high energy physics (HEP) and the theory-ladenness of the data. In the data analysis of CDHS, computer simulations entered an iterative process of probabilistic data correction. The computer simulation was a crucial ingredient of the data analysis that served to increase the accuracy of the measurement. The way in which simulation was used corresponds in a certain sense to the function of \"models as mediators\" (Morgan and Morrison), by mediating knowledge about measurement errors and the way of correcting them. I argue that this use of simulation did not give rise to a vicious circle of adjusting data to theory and vice versa but only to a weak, or benign, theory-ladenness of the data compatible with scientific realism. In the publication of the CDHS results, the measurement outcomes are called \"observed data\", indicating a realist attitude of the physicists towards the measured quantities which does not exactly fit in with entity realism or theory realism.
摘要：
本文介绍了1983年进行的粒子物理CDHS散射实验中的数据分析案例。案例研究将计算机模拟在数据分析中的作用与最近的哲学工作进行了比较，研究了模拟在高能物理（HEP）中的作用以及数据的理论宽大性。在CDHS的数据分析中，计算机模拟进入了概率数据修正的迭代过程。计算机模拟是数据分析的重要组成部分，可提高测量的准确性。模拟的使用方式在某种意义上对应于“作为中介的模型”的功能(摩根和莫里森)，通过调解有关测量误差的知识以及纠正测量误差的方法。我认为，这种模拟的使用并没有引起将数据调整为理论的恶性循环，反之亦然，或者良性的，与科学现实主义兼容的数据的理论宽大性。在CDHS结果的公布中，测量结果称为“观察数据”，表明物理学家对测量量的现实主义态度，这并不完全符合实体现实主义或理论现实主义。
