This paper presents the results of a study that compares CTOM, a microscopic optical model potential(OMP), which is an optical model co-created by the China Nuclear Data Center & Tuebingen University, to CH89, which is a typical phenomenological *** respective OMPs were tested by applying them to the modelling of nucleon elastic scattering and(d,p) transfer reactions involving14C,36S, and58Ni targets at both low and relatively high energies. The results demonstrated that although both potentials successfully accounted for the angular distributions of both the elastic scattering and transfer cross sections, the absolute values of the transfer cross sections calculated using CTOM were approximately 25% larger than those calculated using CH89. This increased transfer cross sections allowed CTOM to produce single particle strength reduction factors for the three reactions that were consistent with those extracted from(e,e′p) reactions as well as with more recent(p,2p) and(p,pn) reactions. Notch tests suggested that nucleon elastic scattering and transfer reactions are sensitive to different regions of the OMP;accordingly,phenomenological OMPs, which are constrained only by elastic scattering cross sections, may not be sufficient for nucleon transfer reactions. Therefore, we suggest that microscopic OMPs, which reflect more theoretical considerations, should be preferred over phenomenological ones in calculations of direct nuclear reactions.

食物过敏是机体免疫系统对某些食物的异常反应,在世界范围内引起了广泛关注.食物过敏通常是由免疫球蛋白E或免疫细胞介导的.食品中所包含的致敏蛋白(过敏原)是导致食物过敏的主要因素之一,对过敏原的检测和鉴定对于确保食品安全至关重要.水产品作为人类重要的蛋白质来源,是人们日常饮食中不可或缺的一部分,对水产品中过敏原的检测非常必要.本综述简述了近年来鱼类和贝类等水产品中过敏原检测的研究进展,对常见的过敏原、过敏原检测方法和技术、当前研究中存在的挑战及未来的发展趋势进行了总结和展望.目前,食品中常见过敏原的检测方法依然存在检测效率和准确性低、成本昂贵等局限性,将不同技术方法相结合,建立高效、准确、低成本的过敏原检测方法仍是该研究领域发展的重要趋势.
