我在这里报告成功的解决了负染色过氧化氢酶晶体的相位问题，使用电子显微镜中产生的衍射和图像平面图片。结果显示了在显微镜像平面内完整的波函数、相位图和振幅图。Gerchberg和Saxton 1描述了用于实现解决方案的计算方法，他们在一般数学函数上演示了该技术;该方法后来成功地应用于磁性薄膜的数学模型2。我现在已经在电子显微镜下将该方法应用于一个真实的生物晶体。
I REPORT here the successful solution of the phase problem for a negatively stained catalase crystal using diffraction and image plane pictures produced in an electron microscope. The results show the complete wave function, phase as well as amplitude maps, in-the microscope image plane. The computational method employed in achieving the solution has been described by Gerchberg and Saxton1 who demonstrated the technique on general mathematical functions; the method was later successfully applied to mathematical models of magnetic thin films2. I have now applied the method to a real biological crystal in the electron microscope.
