An analytical result is given for the wavelength at which two or more first order Laue zone (FOLZ) lines intersect at a single point on the positive x axis when a face centred cubic crystal is observed in the convergent beam mode with the beam axis parallel to the [100] direction. The position of the intersection along the x axis is also given. The method uses the kinematic approximation of electronic diffraction and the exact hyperbolic form of the FOLZ lines, so that the accuracy is good even for lines that intersect at small angles.
给出了一个分析结果，即当在会聚束模式下观察面心立方晶体且束轴平行于[100]方向时，两条或更多一阶劳厄区（FOLZ）线在正x轴上的单个点相交处的波长。还给出了交点沿x轴的位置。该方法使用电子衍射的运动学近似以及FOLZ线的精确双曲线形式，因此即使对于以小角度相交的线，精度也很高。
