According to the plan for FY2019, research work in April and May of this year was focused on the processing of experimental data, collected in situ, inference of general trends and regularities. Obtained experimental data were systemized for determination of phase relationships and change of fluids speciation at different temperature and pressure conditions in the stability field of diamond. Results were compared with the previously published data and important conclusions are made, which were presented at the conference with the participation of international organizations and then prepared for publication in the international journal.

根据2019财年的计划，今年4月和5月的研究工作重点是实验数据的处理、现场收集、总体趋势和规律的推断。将获得的实验数据系统化，用于确定金刚石稳定场中不同温度和压力条件下的相关系和流体形态的变化。结果与之前发表的数据进行了比较，得出了重要结论，并在国际组织参与的会议上提出，然后准备在国际期刊上发表。
