Results: Compared with those of normal cell, the specific surface and numerical density of the mitochondrion and the lysosome in the mid and late stage were decreased.

结果：研究发现癌细胞与正常细胞比较，线粒体和溶酶体的比表面、数密度均减小。

METHODS By using transmission electron, image-manipulation system techniques, the volume density, mean diameter of the granules and numerical density of the atrial specific granules were studied.

方法：采用透射电镜拍照及观察，高清晰彩色图像分析系统对照片的心房肌细胞特殊颗粒的体密度、数密度及颗粒平均直径进行数据处理等研究方法。

Instead researchers track it using numerical simulations, which show that all CDM halos in virial equilibrium have similar density profiles.

幸而研究人员依赖数值模拟，发现处于均功平衡的所有CD M晕都有类似的密度特性。
