The results can be explained in terms of better phase separation and higher melting temperatures of the urea linkages over the urethane linkages.
这可用脲键比氨酯键有较好的相分离和较高的熔化温度来说明。
It is applied extensively in automatic domains like melting, oil production and liquid separation, but less used in mineral processing.
在自动化领域有着广泛的应用，如冶炼、石油和液体分离等，但在选矿方面应用较少。
There were many methods for preparing cobalt metal of 99.999% purity, such as extraction, membrane separation, ion exchange, electrolysis, zone melting etc.
目前制备99.999%以上金属高纯钴的制备方法很多，主要制备工艺有萃取法，膜分离法，离子交换法，电解法，区域熔炼法等方法。
