细颗粒物(PM_(2.5))对农村环境空气质量评价的影响分析

为了评估细颗粒物(PM2.5)监测对农村空气质量等级的影响,2014年在3个村庄监测了二氧化硫(SO2)、二氧化氮(NO2)、吸入性颗粒(PM10)和细颗粒物(PM2.5)等污染指标,使用环境空气质量标准(GB 3095-2012)和环境空气质量指数(AQI)法进行评价。结果显示:农村环境空气质量评价等级在细颗粒物(PM2.5)纳入评估后有所降低,等级为优的比例从29.7%下降到1.7%,等级为良的比例从70.3%提高到95.0%,同时轻微污染的比例从0提高到3.3%。环境空气质量指数(AQI)法对空气污染物有了更准确的评价,能评估未超标情况下空气污染物对空气质量的贡献程度。PM2.5与PM10有显著的正相关关系。     

“爱”的伦理整合力与构建和谐社会

爱作为对人类生存问题的回答,其本质是通过把在伦理关系上相统一而又分离的事物重新整合起来,以化解各种伦理关系之间的矛盾和冲突。爱的本质在全面构建和谐社会的过程中具有重要的现实价值和时代意义:即通过爱自身的整合力量能够激励道德主体扬弃身与心、个体与伦理实体以及天人之间的分离,从而实现身心关系、人伦关系、天人关系的整体和谐。

《金瓶梅》与《红楼梦》比较

本文从三个方面对《金瓶梅》与《红楼梦》作比较研究：从题材选择看,两部书的表现内容均为：描写家庭日常生活;把妇女作为主要描写对象。但《红楼梦》选取的封建家庭更具典型意义,塑造的女性形象更具典型性。从人物塑造看,《金瓶梅》塑造人物的艺术手法主要有：通过日常生活细节的描写来刻画人物;写出人物性格的复杂性;描写室内陈设,陪衬或反衬人物性格。《红楼梦》对此一一借鉴,而且更为摇曳多姿,各臻其妙。从语言运用看,《金瓶梅》的语言风格对《红楼梦》有很大影响;《红楼梦》吸取《金瓶梅》优点,形成自己独有的语言特色,语言艺术超过《金瓶梅》。结论：《金瓶梅》对《红楼梦》影响巨大,《红楼梦》对《金瓶梅》继承发展。     

Here is something you can't understand: the suffocating whiteness of communication studies

ABSTRACT

The authors utilize a modernity-coloniality framework to highlight practices of whiteness and white dominance within the academy and the field of communication studies in particular. The article grounds its framework in personal experience and theories in the flesh to build comradery with feminist of color scholarly forebears and to share with those who struggle to create spaces of change within the academy today and in the future. The authors advocate for an active consciousness of “included exclusion” as the first step toward decolonization. Decolonizing discursive and embodied knowledges creates avenues for social justice and change within the academy and beyond.     

非白噪声干扰下的ARMA模型

关于意识的本质问题

现行教科书对意识本质的理解存在种种矛盾。其中最关键的意识内容的客观性需要反映论支持，而反映论的摹本－原本观念并没有现实根据。对意识本质的揭示只能依据意识自身的内部结构，不能借助意识与外在于它的事物的关系。     

Study on source rock potential and source rocks spatial distribution in the Manghan Faulted Sag, Kailu Basin

Manghan Faulted Sag is an exploratory target area in Kailu Basin. In order to determine its exploration prospect, the effectiveness of its source rocks is evaluated by organic geochemical behavior analysis of the samples, and their distributions are predicted using trace integration seismic inversion technology. Studies on their organic matter abundance, type and maturity indicate that the source rocks in the Sag have great generating potentials. Furthermore, it is found that, based on the spatial distribution predication, the source rocks in the Sag are well developed. Therefore, the Sag has a promising prospect for exploration.

通过对小白鼠内服叠氮钠进行急性毒性试验和蓄积毒性试验测出了叠氮钠的半数致死量(LD50)35.81mg/Kg,为剧毒物质和在动物机体内的蓄积系数K值为3.25,属于中等程度蓄积,并通过对蓄积毒性试验死亡的小白鼠进行解剖,肉眼可见肝脏有点状坏死灶,提示叠氮钠对肝脏有明显的损伤作用,而其它组织如:肾脏、脾脏、肺脏、胃肉眼观察则无明显的病理变化.     

The lower body muscle activation of intermediate to experienced kayakers when navigating white water

In white-water kayaking, the legs play a vital part in turning, stabilising and bracing actions. To date, there has been no reported information on neuromuscular activation of the legs in an authentic white-water environment. The aim of the current study was to identify lower body muscle activation, using ‘in-boat’ electromyography (EMG), whilst navigating a white-water run. Ten experienced male kayakers (age 31.5?±?12.5 yr, intermediate to advanced experience) completed three successful runs of an international standard white-water course (grade 3 rapids), targeting right and left sides of the course, in a zigzag formation. Surface EMG (sEMG) outputs were generated, bilaterally, for the rectus femoris (RF), vastus lateralis, biceps femoris and gastrocnemius, expressed as a percentage of a dynamic maximal voluntary contraction (dMVC). Only RF showed significantly higher activation than any muscle on the left side of the body, and only on the left side of the course (P?=?.004; ETA²?=?0.56). Other results showed no significant difference between muscle activation in the right and left legs during each run, nor when assessed at either the right or left side of the course (P?>?.05). These findings indicate that contralateral symmetry in lower limb muscle activation is evident during white-water kayaking. This symmetry may provide a stable base to allow more asymmetrical upper body and trunk movements to be fully optimised. Lower body symmetry development should be considered useful in targeted training programmes for white-water kayakers.
