The high temperature and abrupt pressure drop ensuing in the process may result in partial melting, material migration and unloading of hydrothermal fluids to trigger litho metallogenesis.
此时温度较高和压力骤降，导致部分熔融和流体卸载，这一转化过程产生的温度、压力和流体浓度等梯度变化，促使流体（物质）运移与富集导致成岩成矿。
The stabilizing agent made the melting process steady because it held back cross-linking and aging of PVA at high temperature.
稳定剂的添加，可明显改善PVA的熔融加工稳定性，使其交联老化程度降低，薄膜的溶解性能显著提高；
