核径迹综合防伪标识介绍：
Introduction of nuclear track integrated anti-counterfeiting mark：
核径迹综合防伪标识图案由每平方厘米几十万到几百万个微米级微孔组成。微孔在光线下反射形成白色图案。微孔孔径很小，孔数很多，微孔在平面上按统计规律分布，孔道为圆柱形，具有良好的透气、透水性能。通过模拟试验，证明利用激光打孔或机械加工手段，无法制得和核微孔防伪膜类似的产品。The nuclear track comprehensive anti-counterfeiting mark pattern consists of hundreds of thousands to millions of micron-sized micropores per square centimeter. The micropores are reflected under light to form a white pattern. The pore size of the micropores is very small and the number of pores is very large. The micropores are distributed according to statistical laws on the plane. The pores are cylindrical and have good air permeability and water permeability. Through simulation test, it is proved that products similar to nuclear microporous anti-counterfeiting film cannot be produced by laser drilling or mechanical processing.
核径迹综合防伪标识的制造过程是一个核物理、光电、生化等多个学科知识交织组合应用的过程，需要强大的科技力量和昂贵的设备支持做保证，其技术难度高，工艺复杂性不是一般的商业企业可以涉足的。The manufacturing process of nuclear track integrated anti-counterfeiting mark is a process of combining knowledge of nuclear physics, photoelectricity, biochemistry and other disciplines. It needs strong scientific and technological strength and expensive equipment to guarantee it. Its technical difficulty is high, and its technological complexity is not something that ordinary commercial enterprises can set foot in.
核径迹综合防伪标识的特点：
Features of nuclear track integrated anti-counterfeiting mark：
1．核孔膜的制造需要尖端的核技术和昂贵的核设施，这些敏感的核设施都控制在的大型核技术研究单位里，都在国家核安全局的监管之下，造假者很难具备。The production of nuclear pore membranes requires sophisticated nuclear technology and expensive nuclear facilities. These sensitive nuclear facilities are under the supervision of the State Nuclear Safety Administration and are difficult for counterfeiters to possess.
2．一般核电站的反应堆不能用来制造核径迹防伪膜，只有特殊结构的反应堆才能用来制造核径迹防伪标识。
The reactors in general nuclear power stations cannot be used to make nuclear track anti-counterfeiting films, and only reactors with special structures can be used to make nuclear track anti-counterfeiting marks.
3. 核孔膜的制造需要高质量的科技人员．高能物理技术和核技术，都是当今世界的尖端技术，在世界上也只有少数国家能掌握。 The manufacture of nuclear pore membranes requires high-quality scientific and technical personnel. High - energy physics and nuclear technology are cutting-edge technologies in the world today, and only a few countries in the world can master them.
4．孔在微观上分布是不均匀的，按随机规律分布．由重离子加速器生产的核径迹防伪标志膜，它的孔道基本是平行的，而用核反应堆生产的核径迹防伪标志膜，它的孔道是有一定的散射角分布的，后者更不容易仿造。The holes are distributed unevenly on the microscopic level and randomly. The nuclear track anti-counterfeiting mark film produced by heavy ion accelerators has basically parallel channels, while the nuclear track anti-counterfeiting mark film produced by nuclear reactors has a certain scattering angle distribution, and the latter is less likely to be imitated.
