Calculations are presented which indicate an extensive suboptical region in the microscopy of biological materials in their natural state which is accessible to ultrasoft x-ray transmission microscopy. Throughout most of the region, radiation dosage levels to the specimen are lower than in electron microscopy.
计算结果表明，在生物材料的自然状态显微镜观察中，存在一个广泛的亚光学区域，超软X射线透射显微镜可以观察到该区域。在该区域的大部分范围内，样品所接受的辐射剂量水平低于电子显微镜观察时的剂量水平。
