科技导报 , 2014,
Abstract: 发布申请通告,是科学基金管理的年度工作之一,主要目的是加强对科学基金依托单位和申请人的宏观引导明确申请要求。浙江省自然科学基金委员会(以下简称省基金委)在管理实践中,除从组织申请规范评审的角度完善申请政策外,还探索了从加强科学基金使用绩效的角度制订政策,将科学基金管理后续环节的相关要求前置到申请通告中进行引导,较好地提高了管理效能。
微震仪设计试验中的一些问题

地球物理学报 , 1964,
Abstract: 一、前言我国在地方性微弱地震的研究中,主要是使用烟紙記录的581型微震仪。从数年来野外观測的結果表明:在設备条件較差的情况下,仪器性能有所降低,因而有改进的必要。今对观測中出現的一些問題,即放大倍率的稳定性、頻带的展寬、笔尖摩擦影响和时間服务等問題作了一些討論,并在此基础上制作了改进的模型。

粪便微生物粗提液通过抑制NF-κB信号的抗溃疡性结肠炎研究
徐敏
- , 2016, DOI: 10.13982/j.mfst.1673-9078.2016.11.006
Abstract: 本文研究了粪便微生物粗提液对人工诱发溃疡性结肠炎小鼠的治疗作用。将64只健康小鼠随机分为4组,即完全空白组(n=20)、肠炎空白组(n=20)、SASP(柳氮硫胺吡啶)组(n=12)和FMT(粪便微生物移植)组(n=12),处理组小鼠自由饮用3%葡聚糖硫酸钠盐(DSS)溶液7 d,建立溃疡性结肠炎(UC)模型;造模后,SASP组、FMT组同时分别给予柳氮硫胺吡啶片及鼠源粪便微生物提取液干预治疗4周,灌胃频率2 d/次,然后进行为期两周的后续观察。结果显示:与肠炎空白组小鼠相比,粪便微生物粗提液使UC小鼠血清IL-1β、IL-6和TNF-α水平显著降低(p<0.05),并降低NF-κB的蛋白表达,增加IκB的蛋白表达。研究表明:粪便微生物粗提液可通过抑制NF-κB信号通路的活化来发挥抗溃疡性结肠炎功效,具有应用于临床医学的潜力。
The effect of crude extract of fecal microbiota on artificially-induced ulcerative colitis in mice was investigated in this study. A total of 64 healthy mice were randomly divided into four groups: blank (n=20), enteritis blank (n=20), sulfasalazine (SASP, n=12), and fecal microbiota transplantation (FMT, n=12). Mice assigned to the treated groups were allowed to freely drink 3% dextran sulfate sodium salt (DSS) solution for seven days, to establish the ulcerative colitis (UC) model. Subsequently, mice in the SASP and FMT groups were treated with SASP solution and crude extract of fecal microbiota for four weeks, respectively. Mice were observed for two weeks with a gavage performed once every two days. The results showed that compared with the enteritis blank group, crude extract of fecal microbiota significantly decreased serum interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α levels (p<0.05), reduced nuclear factor (NF)-κB protein expression, and increased the level of IκB protein expression. The results indicate that crude extract of fecal microbiota exerts an anti-colitis effect by suppressing activation of the NF-κB signaling pathway and has potential applications in clinical medicine.

Abstract:

近年来,随着我国严峻就业形势的不断加剧,性别歧视问题已成为影响女性自身发展和社会和谐进步的巨大障碍。作为女性中的一类特殊人群——女性农民工,受到的压力和歧视更为严重。本文基于对相关已有研究的概括总结,分别从社会视角和经济视角两个角度阐述了女性农民工在就业中性别歧视现象的影响因素,构建了性别歧视影响因素模型,并利用访谈分析法对模型加以验证,为改善女性农民工的就业性别歧视现象奠定良好基础。
In recent years, along with the increasing severe employment situation in our country, gender discrimination has become a big obstacle to women’s development and social harmony. Female peasant- laborers, as a special crowd of women, have been given much more pressure and discrimination. Respec- tively from the social and economic perspective, this paper expounds the influential factors of sex discri- mination appearing in the process of female employment to build the factors’ model, which affects sex discri- mination and is verified by using interview analysis. This article is to improve the sex discrimination of female peasant-laborers employment in employment.

心里发展与教育 , 1994,
Abstract: 本研究的目的在于探讨儿童解决算术应用题的认知加工过程。实验采用个别交谈的临床方法,被试是学前及小学儿童,共125名,4~8岁,分成5个年龄组,每组25名,实验材料是6道算术应用题。研究表明,儿童解题的认知能力可分为四级水平。在各级水平上,问题表征、算法选择及计算策略的运用都表现出不同的特点。在此基础上,我们初步构建了儿童解决算术应用题的认知加工模型。此外,本研究对由briars、larkin以及由riley、greeno和heller提出的有关模型也提供了一个实验论证。
