The effect of chronic emotional stress on the behaviors of rats and its changing trend

open access: yes, 2003
目的探讨空瓶刺激诱发的慢性情绪应激对大鼠行为的影响及行为变化的趋势.方法利用空瓶刺激诱发的情绪应激模型,观察记录连续14次,每次10分钟的情绪应激期间,情绪应激组、对照组和生理应激组大鼠的攻击性行为、探究行为和修饰行为的表现.结果连续14次的情绪应激期间,与对照组和生理应激组相比,情绪应激组大鼠均表现出明显的攻击性行为,而对照组和生理应激组大鼠仅表现为探究和修饰行为.结论慢性情绪应激能诱发大鼠行为的明显改变,且这种行为的改变与应激频率无关.中国科学院知识创新工程项目 ...

计及高比例新能源配电网电压风险的储能容量优化配置方法

open access: yesDianci bileiqi, 2023
为降低高比例新能源配电网电压越限风险和线路潮流越限风险,本研究提出一种计及高比例新能源配电网电压风险的储能容量优化配置方法。该方法首先识别高比例新能源带来的电压越限风险和线路越限风险,并基于效用理论构建量化模型;接着建立风、光、荷的概率模型,确立储能运行控制策略,在考虑配储经济性条件下,建立以系统风险最小为目标的储能选址定容优化模型,最终通过算例确定储能最优安装位置和容量以及运行方式,结果表明储能多点分散接入能降低高比例新能源配电网风险值,验证了所提方法的可行性。

HAIN用于检测原发性耐药结核的研究

open access: yesZhongguo shiyan zhenduanxue, 2014
目的通过与传统的比例法在新发涂阳病人中对结核分枝杆菌进行耐药检测比较,评价HAIN(线性探针)用于检测原发性耐药结核的可行性。方法随机抽取我院2012年1月至2013年3月新发涂阳病人的痰标本,分别进行HAIN检测和酸性罗氏培养、比例法药敏试验,并对结果进行分析比较,共323例病人被纳入分析。结果以比例法为金标准,HAIN方法对异烟肼(P=0.823)和利福平(P=1.000)的耐药检测结果与金标准的差异无统计学意义,HAIN检测异烟肼耐药的灵敏性为80.4%、特异性为96.6 ...

Relative Habitat Suitability of the Gray Fox (Urocyon cinereoargenteus) in the Central Great Plains 大平原中部灰狐 (Urocyon cinereoargenteus) 的生境相对适宜性

open access: yesWildlife Letters, Volume 4, Issue 2, Page 94-101, June 2026.
Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...
