, 2023 天然气压力能是一种新兴清洁能源，对其进行高效利用是节约能源、降低碳排放的有效手段。目前，天然气压力能回收利用中存在用能模式单一、评估指标片面以及评估方法缺乏等问题，导致天然气压力能利用率低，运行效益和系统不足无法被准确评估，行业发展受阻。首先，提出了天然气压力能综合利用方案，使用透平膨胀机回收压力能发电，降压过程中产生的冷能用于制冰，并加入太阳能热水系统提高出站气温度，提高能源利用效率。其次，基于分析模型并考虑经济性和环保性构建了压力能利用系统运行效益评估指标体系，对系统的运行状态进行全面、综合的评估 ...

Psychometric framework for coexistence with large carnivores
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

Dizhen xuebao, 2023 由于常用的均方根值法和噪声功率谱法不能消除不同传感器记录的噪声干扰，为提高噪声水平计算的准确度，本文选用最大概率峰值位移作为背景噪声评估指标。基于可靠的噪声数据，借鉴震级-最大距离监测能力法并考虑预警时效，提出了地震预警最小震级评估方法，系统评估福建三类传感器网及其融合网的地震预警最小震级和预警首报时间。结果表明：测震强震融合网的地震预警最小震级高于单测震网，但明显低于强震网；强震烈度计融合网与单烈度计网的结果相近；三网融合后95%区域的地震预警最小震级约为ML3.2。由于烈度计网比测震和强震网密集 ...

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

18F-FDG PET-CT对滤泡性淋巴瘤诊断及预后评估的作用
Zhongguo shiyan zhenduanxue, 2012 目的评估18氟-氟代脱氧葡萄糖-正电子发射计算机断层显像（fluorine-18fluorodeoxyglucose positron e-mission tomography,18F-FDG PET/CT）对滤泡性淋巴瘤（follicular lymphoma,FL）患者的诊断及预后的预测价值。方法回顾分析2005年4月至2009年7月我院收治67例初治滤泡性淋巴瘤患者,分别与6周期CHOP±R方案化疗前后行PET/CT检查,评价其对临床分期及预后评估的价值。结果 PET/CT对初始分期准确度较CT高,
