初始扫描会得到一张分辨率为500微米的图片。
That done, sections of the core 2-3cm long, whose porosity is of particular interest, aresubject to further study.
这些完成之后,将一些长度在2至3厘米间,其孔隙度有特殊研究价值的小岩石块做进一步研究。
This involves scanning them in a special micro-CT machine, of a sort developed originally tolook at computer chips.
这包括将岩石核样本放入一台特殊的微CT机进行扫描微CT机原是为了观察电脑芯片而研制的。
The sample is placed on a turntable and rotated inside this microscanner.
将小岩石核样本放置在微扫描器内部的转盘上并使其旋转,
The result is a 3D image with a resolution of 40 microns.
结果得到一个分辨率为40微米的三维图像。
This allows sections requiring further study to be identified.
这就使得需做进一步研究的小岩石块能够被标识。
These sections are dissected, using a laser, into slices a millimetre or less thick, and thenscanned again, either with the micro-CT or with a scanning electron microscope.
采用激光将这些小岩石块切分成一毫米或不太厚的薄片,然后用微CT机或电子显微扫描镜对其再次扫描。
