我国"油井管工程"标准化进展

阐述了“油井管工程”的概念和内涵,对中国“油井管工程”标准化的现状、进展和发展方向作了概述、指出．“油井管工程”是合理使用油井管的系统工程,“油井管工程”标准化是以标准来规范管柱设计验证、选择和评价、采购、检验、使用和维修等过程,以保证;由井管使用的安全可靠性;现场作业标准是“油井管工程”的重要内容,目前国内油井管等同、等效采用API．ISO标准,产品标准较齐全,但仍存在新型管材标准缺乏等一些问题、发展我国“油井管工程”标准化．应以等同采用API．ISO油井管标准、发展特殊螺纹产品标准为重点,制定并不断完善我国“油井管工程”标准体系、为此．要跟踪研究国内外油井管工程技术现状和发展,结合现场实际工况条件制定附加技术条件的规范或标准,使标准体系适应油田开发发展。

一种利用短时DFT分析实现全数字2DPSK接收机解调的新算法

本文提出了一种简单而实用的利用短时DFT（ST-DFT）分析实现全数字2DPSK接收机的解调算法。该算法对由多谱勒效应引起的时变频率漂移具有鲁棒性。由于该算法是通过检测在载频处的瞬时能量谱的跳变来实现2DPSK信号的解调，所以该算法不需要进行专门的载波相位恢复、符号定时，且具有较好的抗噪性能，实现起来简单。

Impacts of Market-based Environmental Regulation on Green Total Factor Energy Efficiency in China

This study employed a difference-in-differences design to assess the effect of market-based environmental regulation on green total factor energy efficiency (GTFEE) in a quasi-natural experiment that investigated China's carbon emissions trading scheme (ETS). The empirical results show that ETS had a positive effect on GTFEE. A series of robustness tests revealed that the results were robust. Potential mechanisms through which ETS can improve GTFEE include the promotion of technological innovation and the upgrading of industrial structure. The positive effects varied in different cities and different regions – the result was pronounced in eastern China and developed cities, but it was insignificant in central and western areas and developing cities. This study confirms the satisfactory performance of China's ETS in improving GTFEE, and this is relevant for other emerging countries.

The Potential Market for GM Rice with Health Benefits in a Chinese High-Risk Region

Genetically modified rice with a high folate content, i.e., folate biofortified rice, was recently developed to tackle folate deficiency. A consumer segmentation study is conducted to explore its market potential in the Chinese Shanxi Province, where the burden of folate deficiency is among the world’s highest. Cluster analysis of 451 rice consumers identified three segments: enthusiasts (14.2%), cautious (41.2%), and opponents (44.6%). Enthusiasts obtain the highest score of GM food knowledge and attitudes and have the highest GM rice acceptance rate, followed by cautious and reluctant consumers. Regarding GM food information, enthusiasts use almost entirely audiovisual channels and rely more on the industry, while other segments depend more on informal channels and anti-GM sources. Trust levels in these channels/sources differ between enthusiasts (high), opponents (neutral), and cautious (low). Based on multinomial regression, a targeted communication approach is recommended with a focus on female, cautious consumers and rural, low-educated opponents.
