The main steps include as follows: CO2 is led into the mother liquor of sodium meta-aluminate to carry out carbon content decomposing; the primary separation between the aluminum and the gallium is realized by primary carbonatation to filter out sodium hydroxide; secondary carbonatation is carried out on the filtrate to obtain the deposit of the complex salt of gallium and aluminum; a sodium carbonate crystal is obtained after the filtered filtrate is condensed and vaporized; the deposit of the complex salt of gallium and aluminum is dissolved in the mother liquor of sodium meta-aluminate; the processes are repeated until the proportion of gallium and aluminum in the complex salt of gallium and aluminum is larger than 1/340; then the complex salt of gallium and aluminum is added into the NaOH liquor and electrolyzed, thus obtaining the metal gallium with a purity larger than 99.9 percent which reaches the level of 3; simultaneously, the byproducts of the aluminum hydroxide and the sodium carbonate during the process of carbonatation by steps are obtained.

主要步骤包括：向铝酸钠母液中通入CO 2 进行碳分分解，一次碳酸化实现铝镓的初次分离；过滤出氢氧化钠，滤液进行二次碳酸化获得镓铝复盐沉淀，过滤后滤液经浓缩蒸发获得碳酸钠晶体，铝镓复盐沉淀溶解在偏铝酸钠母液中，重复上述过程直至铝镓复盐中的镓铝比例大于1/340，将其加入到NaOH溶液中，电解可获得纯度＞99.9％的金属镓，达到3N级水平同时在分步碳酸化的过程中获得氢氧化铝和碳酸钠副产品。

Mature, synrift lacustrine shales of Eocene to Oligocene age and mature, late rift coals and coaly shales of Oligocene to Miocene age are source rocks for oil and gas in two important petroleum systems of the onshore and offshore areas of the Northwest Java Basin.

With the seismic profile and the comparison between the eustatic sea level change and sequence, the authors find that there developed different scales of reef and carbonate platforms in the sag. These reef and carbonate platforms have many developing stages which can be correlated with the eustatic sea level change and evolutionary stages, besides, they all have preferable hydrocarbon potential.

通过地震资料的解释及海平面变化曲线与层序的对比发现，琼东南盆地南部深水凹陷发育有规模大小不等的生物礁和碳酸盐岩台地，而且这些生物礁和碳酸盐岩台地的发育与海平面变化曲线和构造演化的阶段可以对应起来，应具有较好的油气勘探潜力。

Based on the analysis of sequence stratigraphy and seismic stratigraphy of carbonate platforms, especially to the ones in Dongsha and Xisha, this dissertation has identified, for the first time, three major and several minor drowning events of the platforms since Tertiary. Drowning events in the four carbonate platforms, especially in Dongsha Platform, coincide with major global eustatic cycles raised by B.
