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.

A new model for the life prediction of GH4133 under TMF conditions

Thermal mechanical cyclic strain tests were carried out under in-phase and out-of-phase conditions on a Nickel-base Superalloy GH4133 in the temperature range of 571-823℃. Based on analyzing the present models of TMF (thermal mechanical fatigue) life prediction, a new model for predicting nickel-base superalloy TMF lifetime was proposed.TMF life of superalloy GH4133 was calculated accurately based on the new model. Experimental TMF life has been compared with the calculatedresults and all results fall in the scatter band of 1.5. The calculating results show that the new model is not only simple, but also precise. This model will play great roles in life prediction of the metal materials and the engineering components subjected to non-isothermal service conditions.

一阶非线性非完整系统的改进的Routh方程

导出了一阶非线性非完整系统的改进的Ｒｏｕｔｈ方程并举例说明其应用，从而提供了建立非完整系统的运动微分方程的一种新方法。该方程的特点在于其第一组方程中只包含系统的独立的广义动量，而第二组方程中不包含任何广义动量。同时，本文结果也是对黄昭度先生的“改进的Ｒｏｕｔｈ方程”一文中的某些错误的修正。
