efforts failed this week to lower a 100-ton steel containment dome onto the leakage site, because quickly accumulated methane hydrates blocked the device.
本周,工程队曾试图将一个100吨重的钢制屋形盖置于漏油点上,不过很快,不断积聚的甲烷冰堵塞了该装置,最终以失败告终。
methane hydrates formed in porous media with different sizes were experimented in laboratory. the concentrations of main ions in pore water before and after experiments were determined.
利用不同粒径的多孔介质模拟了海洋天然气水合物的生成过程,测定了孔隙水中主要离子质量浓度的变化。
even more worrying, however, is the impact of rising sea temperatures on the far greater reserves of methane hydrates that are found on the sea floor.
除此之外,海床上储藏着更为大量的甲烷水化物,而不断升高的海洋温度对此的影响更为令人堪忧。
a empirical equation on the phase equilibrium of methane hydrates is gained by statistics analysis, which has a very good agreement with the experimental data.
本相平衡实验数据与前人的研究数据相结合,得出了一组适合计算甲烷水合物相平衡的经验公式,结果证实该经验公式能够很好地和实验数据吻合。
「the modeling of methane hydrate is frankly in its infancy,」 but it seems 「robust to conclude」 that mankind could 「melt a significant fraction of the methane hydrates in the ocean,」 they wrote.
「坦率地说,甲烷水合物的建模工作尚处于起步阶段,」但它似乎「得出了有力的结论」,即人类的活动可能会「融化海洋中相当一部分的甲烷水合物,」他们这样写道。
the country hopes to turn the seafloor deposits of methane hydrates into a commercial source of natural gas.
这个国家希望把海底库存的甲烷水合物转变成一种天然气商业资源。
