野生动物学报, 1984 啮齿动物对人类是有害的。它盗吃粮食、咬坏家俱,破坏草原,危害森林更新,传染疾病。由于它们适应性强,分布广,繁殖力高,数量增殖快,所以对人类的危害程度日趋严重。已引起人们的关注。

Zhejiang Daxue xuebao. Lixue ban, 2015 利用1971~2013年永嘉县夏季高温资料，建立高温过程的时间序列，分析了夏季高温天气的气候特征，并对出现危害性高温时的预警指标作了进一步探讨.研究表明：永嘉县夏季高温天气具有显著的局地性特征，且高温多集中在7月中下旬和8月上旬；副热带高压是影响本地夏季高温的主要天气系统，当本站处在副高脊线附近，高空下沉气流明显，低层在暖脊或暖中心附近，中高层为西南（或偏西）气流时，容易出现危害性高温；危害性高温出现时，天况稳定、云量偏少、日照时数较长、能见度较好、风速较小，且以西南风居多.

Dry and Wet Deposition Characteristics and Anthropogenic Sources of Atmospheric Mercury in Xiamen [PDF]
, 2016 大气汞是危害人体健康的毒性污染物。大气中不同形态的汞具有不同的理化特性，颗粒态总汞TPM(Totalparticulatemercury)沉降速率高，能在排放源附近沉降，对区域内的生态环境造成较大的危害；大气气态总汞TGM(Totalgaseousmercury)因其具有较低的水溶性和沉降速率，可在大气中停留0.5-2年，能够进行长距离传输，被认为是全球性污染物。目前欧美地区已经广泛地建立起汞监测网络，虽然国内的大气汞监测也陆续开展起来，但是长时间持续监测尚不多见。本研究基于实验室前期的研究成果 ...

Dianci bileiqi, 2016 为合理地防护雷电对人体带来的伤害,需要研究雷电对人体的伤害机理。介绍了雷电对人体的危害方式和雷电危害能量阈值。通过建立人体电路模型,利用ATP软件模拟雷电和与人体模型间相互作用,具体分析不同土壤电阻率情况下,跨步电压、接触电压和转移电位作用下流经心脏的电流,计算导致心室纤维性颤动的比能量。仿真结果表明:土壤电阻率的增大有助于降低跨步电压和转移电位对人体的伤害;接触电压更容易给人体带来致命性危害。雷电作用下人体伤害机理需要作进一步研究。

The Impact of Regulatory Focus in Message Framing in Anti-smoking Advertisements for Adolescents [PDF]
, 2015 本文从调节定向的理论视角，将社会规范信息作为控烟主题，考察两种信息框架（得益框架和亏损框架）的控烟广告对青少年的说服效果。 本文主要包含三个部分的研究，第一个研究结合控烟主题中的社会规范信息，采用单因素（信息框架：得益框架/亏损框架）被试间实验设计，测量两种不同信息框架对青少年信息说服力、情绪体验及行为意向的说服效果。研究结果表明，与控制组和亏损框架组相比，得益框架组的被试对信息说服评价更高，其不吸烟的行为意图更高。另外，本研究还发现，不论是得益框架还是亏损框架的控烟信息，都不会对男生造成任何影响 ...

Downlisting and recovery of species assessed by the IUCN
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Despite the increasing number of species assessed for extinction risk by the International Union for Conservation of Nature (IUCN) (163,040 species as of 2024), only about 1 in 1,000 have been downlisted due to genuine population improvement. Although this rare conservation achievement has been widely celebrated in several recent cases, some ...
