Chinese Journal Of Geochemistry 2008年第4期27卷 377-383页

作者： CHANG Xiangchun DUAN Yunge chen qingchun MA Lixin School of Geo-information Science and Engineering Shandong University of Science and Technology Qingdao 266510 China Linpan Production Plant ofShenli Oilfield Company SINOPEC Linyi 251507 China

The Linnan subsag is the main oil producer of the Linpan oil zone. Based on the oil group composition,gas chromatography data and biomarker analysis,it was indicated that crude oils from different oilfields varied greatly in group composition and showed obvious heterogeneities in the aspects of precursor type,crude oil maturity and hydrocarbon depositional environment. According to the characteristics of source rocks,three oil populations can be distinguished,i.e.,the southern,northern and transitional oil populations. Furthermore,on the basis of post-reservoir reworking processes,the medium conditions of hydrocarbon-generating environment and differences in maturity,six oil families and twelve sub-families were distinquished. An integrated study suggested that the fac-tors leading to such heterogeneities in crude oil composition mainly include different source rocks,multi-stage oil/gas charging,geo-chromatographic effects during oil/gas migration,reservoir heterogeneities and various post-reservoir secondary alterations.

Wireless relay and network coding are two critical techniques to increase the reliability and throughput of wireless cooperative communication systems. In this paper, a complex field network coding （CFNC） scheme with the K-th best relay selection （KBS） is proposed and investigated, wherein the K-th best relay is selected to forward the multiplexed signal to the destination. First, the upper bound of the symbol error probability （SEP）, the diversity order, and the coding gain are derived for the CFNC scheme with KBS. Then, the coding gain is utilized as the optimized cri- terion to determine the optimal power allocation. It is validated through analysis and simulation that the CFNC scheme with KBS can achieve full diversity only when K=I, while the diversity order decreases with increasing parameter K, and the optimal power allocation can significantly improve the performance of the CFNC scheme with KBS.

关键词： complex field network coding the K-th best relay selection power allocation

儒家的"义"概念共有四重具体的伦理涵义,处于中心地位的是选择正义,即意志在伦理实践中的目的、目标和方法三个环节的选择正确性。目的选择的正确性是根据自爱原理选择仁爱作为实践的目的,因而是"仁"的道德体现;目标选择的正确性是根据忠恕原则选择适当的他人价值作为实践的目标,因而是"义"的道德体现;方法选择的正确性是根据最大效用原则选择最有效的技术手段作为实践的方法,因而是"智"的道德体现。但在总体上,每一个环节的选择正确性都是"仁""义""智"的道德体现。

在中西哲学中,“心”和“人格”在存在论上都是表示主体的概念,在伦理学上都是表示道德主体的概念。通过对王阳明的“心”概念与康德、舍勒的“人格”概念的分析与比较,可以看出,它们作为主体概念的本质内涵都是“意向性”、作为道德主体概念的本质内涵都是“责任性”。在存在论上,王阳明与康德更接近,都承认主体的本体性,而舍勒则否定主体的本体性;在伦理学上,王阳明与舍勒更接近,都把道德根据建立在道德情感的直观体验之上,而康德则把道德根据建立在道德法则或义务之上。比较而言,王阳明的“心”概念不仅指广义的实践主体,而且不带有神学和二元论的弊病,因此更具有理论的全面性和自洽性。
