基于GPSJ_1过程下的未决赔款准备金

在非寿险精算领域中,未决赔款准备金的计算需要两个变量:损失额度(或者理赔额度)和理赔次数,其中理赔次数分布的研究具有更大的难度.GPSJ分布类使用面广,包含的分布种类较多,相关的理论也比较完备.通过假设理赔次数服从GPSJ分布类,运用排队论分析方法得到未来某时间段内已完成的未决赔案次数,从而进一步得到未来某时间段内需要计提准备金的分布函数.     

非稳态条件下麻类纤维动态传热性能比较与分析

研究了几种常见麻类纤维(包括汉麻、亚麻、黄麻、苎麻)在非稳态条件下的动态传热性能,并与棉纤维进行对比.采用自行搭建的温度采集系统测试了高温环境(100℃)下每种纤维的动态温升曲线,根据动态传热率描述纤维在初始非稳态传热过程中的动态传热性能.研究结果表明,麻类纤维具有比棉纤维更加优良的动态传热性能,其中以苎麻纤维最优,其次分别为汉麻纤维、黄麻纤维、亚麻纤维.     

Effects of mechanical strain amplitude on the isothermal fatigue behavior of H13

Isothermal fatigue (IF) tests were performed on H13 tool steel subjected to three different mechanical strain amplitudes at a constant temperature to determine the effects of mechanical strain amplitude on the microstructure of the steel samples. The samples' extent of damage after IF tests was compared by observation of their cracks and calculation of their damage parameters. Optical microscopy (OM) and scanning electron microscopy (SEM) were used to observe the microstructure of the samples. Cracks were observed to initiate at the surface because the strains and stresses there were the largest during thermal cycling. Mechanical strain accelerated the damage and softening of the steel. A larger mechanical strain caused greater deformation of the steel, which made the precipitated carbides easier to gather and grow along the deformation direction, possibly resulting in softening of the material or the initiation of cracks.     

Scan Strategy in Electron Beam Selective Melting

In electron beam selective melting process, powder pushed-away phenomena and uneven temperature field are two main obstacles, which are greatly associated with the electron beam scan mode. In this paper, various scan strategies, including iterative scan mode, reverse scan mode, interlaced reverse scan mode, randomized block scan mode, and constant length scan mode, are investigated. The analyses for each scan strategy are presented based on the influence to the temperature field over the formation zone and the powder pushed-away phenomena. The most promising strategy, interlaced reverse scan mode, is approved by the ANSYS simulation and a two-dimensional scan experiment. The result shows interlaced reverse scan mode can improve the uniformity of the temperature field and reduce the powder pushed-away phenomena.

Science Letters: A new quantitative model of ecological compensation based on ecosystem capital in Zhejiang Province, China

Ecological compensation is becoming one of key and multidiscipline issues in the field of resources and environmental management. Considering the change relation between gross domestic product (GDP) and ecological capital (EC) based on remote sensing estimation, we construct a new quantitative estimate model for ecological compensation, using county as study unit, and determine standard value so as to evaluate ecological compensation from 2001 to 2004 in Zhejiang Province, China. Spatial differences of the ecological compensation were significant among all the counties or districts. This model fills up the gap in the field of quantitative evaluation of regional ecological compensation and provides a feasible way to reconcile the conflicts among benefits in the economic, social, and ecological sectors.
