对于天然气水化物晶体的集结和生长可以利用光子相关色谱仪 (PCS)来研究。水化物实验时采用了蒸馏水、过滤净化水和天然气的混合物 ,形成了结构Ⅱ的水化物 ( 94 %mol甲烷和 6%mol丙烷 )。实验研究了几种不同压力、温度下的情况 ,发现天然气水化物集结时 ,晶核大小约为 2～ 80nm ,与驱动力大小有关。实验采用了两种体系 :静态和搅拌状态。静态实验很难恢复感应时间和必要的驱动力。但是 ,在搅拌实验中 ,尤其是当温度较低时 ,恢复能力得到很大增强 The accumulation and growth of natural gas hydrate crystals can be studied using photon correlation spectroscopy (PCS). Hydration Experiments were conducted using distilled water to filter the mixture of purified water and natural gas to form the hydrate of structure II (94% of methane and 6% of mol of propane). Several different pressures and temperatures were investigated experimentally. It was found that the nuclei size of natural gas hydrate is about 2 ~ 80nm, which is related to the driving force. Two systems were used in the experiment: static and agitated. Static experiments are difficult to recover the induction time and the necessary driving force. However, resilience has been greatly enhanced during mixing experiments, especially at lower temperatures
