The reacting cosmic particles producing nuclides primarily include secondary fast neutrons, thermal neutrons and slow negative muons. Due to the differential special distribution of these reacting particles, the production rates of Cosmogenic nuclides at different latitude, altitude and depth are different.

产生宁宙成因核素宇宙射线粒子主要是次生快中子、热中子和负慢介子，由于这些宇宙射线粒子在空间分布上的不同，地球上不同纬度、海拔高度和深度处的宇宙成因核素生成速率也表现出较大的差异。

In practical study, the essential flow is""on the basis of the study of the faults, strata denuded thickness and original thickness, analyzing the controlling effect of the faults to the sedimentation and denudation, and combined with the areal geology background, reconstructing the basin prototype of each stage"". 2. As the basic theories and methods of the calculation of the denuded thickness, such as, the methods of cosmogenic nuclides, wave equation, apatite fission track, structural sections, acoustic wave, vitrinite reflection, etc, were argued detailedly , and their applicable ranges were analyzed , the denuded strata thickness of each structural layer layer of pre-Tertiary was reconstructed.
