ray critical wavelength x 射线临界波长
However, compared to X-ray crystallography, electron crystallography confronts with a critical problem, i. e. dynamical diffraction problem which makes structure analysis very complicated.
然而，由于电子与晶体之间强烈的动力学交互作用，使得用电子显微镜方法分析结构复杂化。
With using the methods of light and scanning electron microscopy and X-ray microanalysis it was shown that a critical level of cartilage calcification is need to activate osteoclasts.
使用该方法的光线和扫描电子显微镜和X -射线微结果表明，一个关键的软骨钙化是需要激活破骨细胞。
Other critical needs are specialists in orthopedic and internal medicine and X-ray equipment.
其他亟需的还有整形外科医生，内科医生和X射线设备。
