Data for: Dynamic in-situ imaging of methane hydrate formation and self-preservation

In this repository we prepared supplementary pdf files for studying gas-hydrate formation processes in time by focusing at different pore locations. Pages in pdf files correspond to sequential time frames associated with the gas hydrate growth, including pore location, temperature and pressure conditions. The left part of each page represents x,y,z-slices of the object recovered by using the data from the scanning region. The right panel shows x,y,z-slices of the zoomed region marked in the left panel. Comments describing the pdf files: cpore1.pdf - gas hydrate growth in a pore as frost (into gas pockets) cpore2.pdf - narrow pore in vertical direction, ice growth in the beginning cpore3.pdf - tracery (inside water pockets) gas hydrate formation cpore4.pdf - tracery gas hydrate formation for a long period cpore5.pdf - fast tracery gas hydrate formation cpore6.pdf - gas hydrate growth with several water flows cpore7.pdf - conservation for gas hydrate grown as the tracery structure (location 1) cpore8.pdf - no conservation for gas hydrate grown as frost (location 1) cpore9.pdf - partial conservation of gas hydrate cpore10.pdf - no conservation for gas hydrate grown as frost (location 2) cpore11.pdf - no conservation for gas hydrate grown as frost (location 3) cpore12.pdf - conservation for gas hydrate grown as the tracery structure (location 2) cpore13.pdf - no conservation for gas hydrate grown as frost (location 4) cpore14.pdf - conservation for gas hydrate grown as the tracery structure (location 3) cpore15.pdf - conservation for gas hydrate grown as the tracery structure (location 4)本数据集仓库中提供了配套PDF文件，用于聚焦不同孔隙位置，时序性研究天然气水合物（gas hydrate）的生成过程。每份PDF的页面对应天然气水合物生长的时序时间窗口，涵盖孔隙位置、温度与压力条件等核心信息。每一页的左侧区域展示由扫描区域数据重构得到的目标对象的x、y、z轴切片；右侧面板则呈现左侧面板中标注的放大区域的x、y、z轴切片。 各PDF文件说明如下： cpore1.pdf：孔隙内以霜状形态（生成于气袋中）的天然气水合物生长过程 cpore2.pdf：垂直方向窄孔隙初始阶段的冰晶生长过程 cpore3.pdf：水袋内部的纹理状天然气水合物生成过程 cpore4.pdf：长时序下的纹理状天然气水合物生成过程 cpore5.pdf：快速纹理状天然气水合物生成过程 cpore6.pdf：伴随多股水流的天然气水合物生长过程 cpore7.pdf：纹理状结构天然气水合物（位置1）的保存过程 cpore8.pdf：以霜状形态生长的天然气水合物（位置1）的无保存过程 cpore9.pdf：天然气水合物的部分保存过程 cpore10.pdf：以霜状形态生长的天然气水合物（位置2）的无保存过程 cpore11.pdf：以霜状形态生长的天然气水合物（位置3）的无保存过程 cpore12.pdf：纹理状结构天然气水合物（位置2）的保存过程 cpore13.pdf：以霜状形态生长的天然气水合物（位置4）的无保存过程 cpore14.pdf：纹理状结构天然气水合物（位置3）的保存过程 cpore15.pdf：纹理状结构天然气水合物（位置4）的保存过程
