Thermal conductivity of THF hydrate containing carbon nanotubes without dispersant is lower than that with dispersant, but it is higher than THF hydrate not containing carbon nanotubes. 对于含纳米碳管的THF水合物,不加分散剂时的导热系数比加分散剂的导热系数低,但高于纯THF水合物的导热系数。
Ketazine process and hydrogen peroxide process had many advantages, such as salt-free, non-pollution, lower cost, lower energy consumption, higher yield and higher purity of the product, etc. Therefore, they represent the development trend of hydrazine hydrate. 酮连氮法和过氧化氢法具有无盐类副产物、无环境污染、原料成本及能耗低、产物收率及纯度高等优点,代表了水合肼生产工艺的发展方向。
It needs higer pressure and lower temperature for the stability of CO2 hydrate in ocean sediments than in pure water. 与在纯水中相比在海洋沉积层中二氧化碳水合物需要更高的压力和更低的温度保持其稳定性。
