建立社会主义市场经济必须首先解放思想

从传统的计划经济向社会主义市场经济的转变，必须从计划经济体制下所形成的旧的思想观念中解放出来，树立适应社会主义市场经济的新观念，这是建立社会主义市场经济的需要。我国十几年的改革开放的实践已证明，在马克思主义的指导下，打破习惯势力和主观偏见的束缚，从实际出发，解放思想，是改革开放和进行社会主义建设的首要条件。

Developmental modes of the Neoproterozoic-Lower Paleozoic marine hydrocarbon source rocks in China

Based on the researches on rock type, the mode of occurrence, diagnostic minerals and creatures, the sedimentary geochemistry and organic facies of Chinese marine source rocks from wells and outcrops, and on the research findings of developmental modes of foreign marine source rock, the authors consider that it is impossible to objectively make clear the formation mechanism of hydrocarbon source rock with high organic matter abundance by either single mode of preservation or high organic matter productivity. According to the Chinese geological features, the formation mechanism of the Neoproterozoic-Lower Paleozoic marine source rock is generalized into four modes, namely, thermal water activity-upwelling flow-anoxic; carbonate gentle slope-upwelling flow; xerothermic climate-brine euxinic milieu; and humid climate-retained euxinic milieu; as the Lower Cambrian undercompensation basin organic facies （the Tarim Basin, South China and southwestern margin of North China）, carbonate gentle lime mud bound organic facies （the Upper Ordovician in Tazhong region of the Tarim Basin and the Lower Silurian in the Upper Yangtze Platform）, the Middle Cambrian evaporation laggon organic facies （the Tarim Basin and the Upper Yangtze Platform）, enclosed undercompensation terrigenous bay organic facies （the Middle-Upper Ordovician in the west of the Tarim Basin, the Lower Silurian Long- maxi Formation in the Upper Yangtze platform）. Chinese marine sedimentations with lower organic matter abundance are generalized into two modes of consumption-dilution mode of open epicontinental sea and depletion-dilution mode of supercompensation basin.

试析仲裁简易程序的适用条件

虽然我国各仲裁委员会在实践中大量适用仲裁简易程序,但我国法学理论界却很少对其时代内涵进行界定,对其适用条件也缺乏探讨,因而制约了仲裁简易程序的研究和发展。本文在分析仲裁简易程序时代内涵的基础上,从主观条件和客观条件两方面对仲裁简易程序的适用条件进行了探讨,建议规范我国仲裁简易程序的适用条件,实现仲裁简易程序的和谐价值取向。
