The Australian wildfires in 2019 and 2020 were historic for how far and fast they spread, and for how long and powerfully they burned. All told, the devastating “Black Summer” fires blazed across more...
中国科学院西北生态环境资源研究院（简称西北研究院）冻土工程国家重点实验室水合物研究团队，对此问题进行了长期跟踪研究，提出是否可以忽略水合物具体生长过程，摆脱由大量模型引入的众多参数干扰，直接考察成核对最终生成的块状水合物晶体影响作用，最终提出初始成核速率可直接影响最终含气率的新水合物形成思路。
