的表达式推导出的误差所产生的差分傅立叶技术的使用。由于使用不准确的AF和相位值的错误被认为是除了那些由于差分傅立叶技术本身。结果表明，差分傅立叶图是能够检测到更小的电子密度的功能比具有相同的相位的正常傅立叶图所揭示的。得到的误差水平最小化的差异图所需的实验条件进行了概述。
An expression is derived for the error which arises from the use of the difference Fourier technique. Errors due to the use of inaccurate values of AF and phase are considered in addition to those due to the difference Fourier technique itself. It is shown that a difference Fourier map is able to detect much smaller features of electron density than those revealed by a normal Fourier map with the same phases. The experimental conditions required to obtain difference maps in which the error level is minimized are outlined.
