The history of electrochemical flotation was reviewed. Potentiometry, voltammetry, rotating disk electrode and spectral electrochemical methods for electrochemical studies of sulfides and sulfide flotation were introduced. The methodology of electrochemical research was expatiated on. Some research of sulfides done by these methods was demonstrated. Their results give good inosculation to the flotation practice. The mixed potential concept leads to an understanding of collector action in terms of well established electrochemical principles. At last, the trend of flotation electrochemistry was predicted.

The production. characteristics. and commercialization of monolithic and composite titanium aluminides are summanzed with emphasis on use in the demanding aerospace industry. The attractive elevated temperature properties combined with alow density make these materials of great interest, but inherently low 'forgiveness', and environmental concerns, must be overcome before widespread use will occur One synthesis method for the production of monolithic titanium aluminides-mechanical alloying- will be discussed in detail

北极圈数据库及为何需要(英)

Many factors, such the great changes of temperature, which will be expected at the high latitudes, increased pressure from humans to extract the natural resources in cold regions, seriously affect the cold environment. Many meetings have been held about the classification of cold soils, ideas and concepts of cold soils. These facilitate the need for developing a database of soils of the circumpolar region. The database can help offering information for potential problems in cold regions and for selecting the best areas for placement of new road and towns.

石油与天然气以其在地球内部的广泛分布、巨大的资源量及其使用的高效性而在世界经济中起主导作用。油气分布与地球生物圈的存在紧密相关。油气是生物圈中被埋藏的生物存在的一种特殊形式。我们应将油气形成与沉积岩的去流体作用相联系，这些沉积岩富含有机质，当达到１００℃的温度条件时，就有油气形成。油气形成是沉积盆地所伴随的一种普遍的作用，并具有其自身的演化体系。沉积盆地产生的油气可上升到达低温、低压带。油气富集而成的油气藏出现于１～２ｋｍ深度处。推测油气生成非常快，因此，我们认为油气可作为再生矿物燃料。

R. China

The Maksyutov complex is a part of Precambrian folded belt extending from Urals, North Karakum, Kunlun, Qilian, Qinling to the Dabie-Sulu belt of eastern China. In Maksyutov the eclogites present as individual blocks and boudines embedded within the glaucophane and micaceous schists. Due to the Phanerozoic multi-phase granite intrusions and their resulting superposed metamorphism the data on the age of eclogite are diverse spanning from Early Proterozoic to lower Paleozoic. The mineral compositions of the eclogite are constant with garnet, omphacite and rutile; however, they are often replaced by metamorphic assemblages of epidote-blueschist facies. The garnets are iron rich with f=50-75 % (f = Fe2./(Mg + Fe2.)). Clinopyroxenes are omphacites with Jd 40.3-52.2. According to the garnet-clinopyroxene geothermometry and Jadeite + quartz→albite geobarometry T=1060-686℃, P=2.2.-1.416 GPa are estimated. The PT trajectory of Maksyutov eclogite corresponds to the upward intrusion of eclogite magma, the final consolidation of the eclogites probably took place in the lower crust.

盆地形成的原因包括；构造圈深部地带物质的不稳定状态、软流圈厚度的增加和继而地壳厚度的减小。大多数沉积盆地均有一些高能不稳定层，反映了岩石特征的非线性交换。在不同岩石类型的不同深度，密度、孔隙度、水饱和度等的异常均不相同。决定异常存在的主要作用是岩石的构造一组分特征和导热性、导电性。采用与深度和ＰＴ因子一致的温度计算法来建立不同岩石类型和不同地球动力条件和热力条件下岩石特征变化的计算机模型或许是重要的。密度、孔隙度等的非线性变化决定了不同流体循环的环型流动的存在，不稳定层的预测是矿产预测之关键。
