The present paper analyzes historically the relationship between carbon emission and economic development by different stages through adopting elastic decoupling methods and Tapio evaluation criteria along with a comparison with the national Five Year Plans. The analysis shows that the influencing factors to the relationship between carbon emission and economy in China are different, and economic development and carbon emission have less connection in the recent 30 years of reform and opening-up in China. It is a difficult task to realize the promise that we will reduce carbon emission by 40%-50% in 2020 based on the data from historical experience and different expectations for economic development from economists. Through constructing the calcula- tion model of carbon emission intensity gap according to different development scenarios, the analysis shows that economic growth, infrastructure investment and further development of industrial-ization are the main drivers to the increase of carbon emission, technological progress, and particularly, the reduction of energy consumption is the primary means to reduce carbon emission in China. It is imperative to transform the economic growth pattern, and it is a grand task to perform and there is a long way to go for China to maintain economic growth and reduce carbon intensity.

The wear forms and reasons of PCBN tools when dry-cutting bearing steel GCr15are studied systematically. The effect law of the workpiece hardness on PCBN tools is gained andtool wearing with the quickest speed at the workpiece critical hardness is proved. The life equationat two kinds of workpiece hardness demonstrates that the effect of the cutting speed on the PCBNtool life is less than that of carbide tools and ceramic tools.

为了提高融合图像的视觉感知效果,提出一种非下采样剪切波变换(Non-Subsampled Shear Transform,NSST)域红外和可见光图像感知融合方法。首先采用NSST将源图像分解为高频和低频分量;接着采用参数自适应脉冲耦合神经网络(Parameter Adaptive Pulse Coupled Neural Network,PA-PCNN)融合高频分量图像,提高成像细节;然后联合使用高斯滤波器和双边滤波器进行多尺度变换以融合低频分量图像,将低频分量分解为多尺度纹理细节和边缘特征以捕获更多的多尺度红外光谱特征;最后利用NSST逆变换获取融合图像。实验结果表明,该方法不仅可以有效提高融合图像的细节信息,而且还能增强红外特征的提取能力以契合人体的视觉感知。

虽然认罪认罚从宽制度目前只规定在《刑事诉讼法》之中,但其是一个综合性制度,其落实离不开刑法的衔接配合。为与刑诉法衔接配套,刑法学科有必要挖掘"认罪认罚"在刑法教义学中的含义,厘清认罪认罚与已有从宽事由的重合之处,探索"认罪认罚"在量刑从宽中的独特价值及"认罪认罚"的从宽依据。"认罪认罚"除了体现被追诉人预防刑的降低之外,还可极大地加快程序流转和提高司法效率,因而具有坦白等已有从宽事由无法涵盖的制度内涵。具体而言,认罪认罚从宽制度的刑法衔接应从以下几方面着手:刑法典对认罪认罚从宽作出原则性规定;明确认罪认罚作为量刑独立从宽事由;规定认罪认罚实体从宽的具体幅度,为认罪认罚案件量刑建议规范化和精准化提供学科支撑。

多氟和全氟烷基化合物(PFASs)由于其独特的稳定性、疏水性和疏油性被广泛用于生产和生活中。PFASs的生产方式有两种:电化学氟化法(ECF)和调聚反应。由于持久性、毒性和生物富集性,ECF生产过程中产生的全氟辛烷磺酸(PFOS)及其盐和全氟辛基磺酰胺(POSF)于2009年被正式列入《斯德哥尔摩公约》的POPs名单,发达国家也开始逐渐停止用ECF方法生产PFASs。因此,调聚反应产生的PFASs前驱体氟调醇(FTOHs)的产量不断增加。研究表明,FTOHs经生物或非生物转化能够生成全氟烷基羧酸(PFCAs),可能是PFCAs污染的间接来源。此外,FTOHs的一些中间代谢产物能够与多种生物分子共价结合,引起严重的毒性效应,而代谢终产物又能引起肝毒性和肾毒性等。近年来,FTOHs的环境问题已成为环境科学、毒理学和流行病学领域的研究热点。本文综述了FTOHs的生产状况、环境污染水平和相关代谢产物的毒性。最后讨论了目前存在的问题,并对未来的研究进行了展望。

本文在分析外汇储备的来源后,对我国外汇储备的成本、收益及部门分布进行了测算,结果表明,外汇储备成本、收益分布非常不均,收益主要流入了外汇管理部门,而成本则由居民和商业银行承担。如果考虑居民和商业银行承担的成本,我国外汇储备成本高达764.9亿美元/年,相当于借入年利为7.2%的资产。最后,作者分析了高额外汇储备成本的挑战,并提出了相应的对策,包括改善国际收支不平衡状况、加大人民币升值的幅度与速度、试点建立外汇基金等。
