从Debye散射方程出发,考虑到晶相中原子的热运动和格子的非完整性,推导出沥青的X-射线散射强度与其石蜡晶相含量x_(cr)的定量关系: integral from n=0 to ∞ S~2I_t(S)dS/integral from n=0 to ∞ S~2I_(cr)(s)dS=1/x_(cr) integral from n=0 to ∞ S~2(?)ds/integral from to ∞ S~2(?)DdS 对于同一物相在结晶状态相同时,其含量的变化只影响散射蜂的面积,不影响形状,因此收集了8~110°(2θ)范围内沥青的散射强度,将其划分为23个段,每段的强度运算处理之后列表备用。在12~26°(2θ)一段内晶相的强度和为5730计数,非晶相的强度和为147572计数。一个样品,当得到它的12~26°(2θ)的散射强度,从中分离出晶相的强度A_(cr)及非晶相的强度A_a,求出比值α=A_(cr)/5730、β=A_a/147572之后,从表中的数据即可引出倒易空间的全部散射强度,进而求得x_(cr)。文中列出了α/β~x_(cr)函数表,因此也可以依照α,β值查表得x_(cr)。
Based on the Debye scattering equation, the quantitative relationship between X-ray scattering intensity of x-ray and the content of paraffin crystal phase x cr is derived from the thermal motion of atoms in the crystal phase and the non-integrity of the lattice: integral from n = 0 to ∞ S ~ 2I_t (S) dS / integral from n = 0 to ∞ S ~ 2I_ (cr) (s) dS = 1 / x_ (cr) integral from n = 0 to ∞ S ~ 2 ds / integral from to ∞ S ~ 2 (?) DdS For the same phase in the same crystal state, the change of the content affects only the area of scattered bees and does not affect the shape, so the scattering intensity of asphalt in the range of 8 ~ 110 ° (2θ) , It is divided into 23 segments, the intensity of each paragraph after the calculation list backup. The intensity of the internal phase in the period of 12-26 ° (2θ) is 5730 counts, and the intensity of the amorphous phase is 147572 counts. A sample was obtained with a scattering intensity of 12-26 ° (2θ) from which the strength of the crystalline phase, A cr, and the strength of the amorphous phase, A_a, were determined and the ratio α = A cr / 5730 β = A_a / 147572, the data in the table can lead to the total scattering intensity of reciprocal space, and then find x_ (cr). The article lists the α / β ~ x_ (cr) function table, so you can also check in accordance with the α, β value table cr (x).
