Abstract: ?2008年初车八岭山地常绿阔叶林受到中国南方80年一遇的冰灾的重创。为了揭示灾后林冠开度的梯度对土壤节肢动物多样性与分布的影响,在受冰灾影响的车八岭山地常绿阔叶林设置2ha固定样地,按照冠层受损程度选取17个20m×20m的样方,用半球面影像技术获取林冠开度,并分凋落物层、0–10cm和10–20cm的矿质土层采集凋落物及土壤样品,分析土壤节肢动物多样性。利用双向聚类分析(two-wayclusteranalysis)对凋落物层的土壤节肢动物和样地进行聚类,以典范对应分析(canonicalcorrespondenceanalysis)研究冠层开度、土壤有机质、电导率以及自然含水量与0–10cm表土层土壤节肢动物的关系。结果表明土壤节肢动物的多度、丰富度和多样性随土壤层的加深而下降,具有明显的表聚性;林冠开度与凋落物层的土壤节肢动物类群数量呈负相关;甲螨亚目、中气门亚目和前气门亚目动物对光照的适应范围广;膜翅目、鞘翅目幼虫、综合纲和伪蝎目动物具有明显的避光性;土壤节肢动物类群的分布与林冠开度、土壤自然含水量、电导率和有机质关系密切。因此可以推论,冰灾对车八岭山地常绿阔叶林冠层的破坏及土壤因子的变化会进一步影响土壤节肢动物群落的组成和分布。本项研究还表明,土壤节肢动物群落能有效地表征它们所栖息的生态系统的特点,可用于监测冰灾后森林恢复和演替动态。而双向聚类分析和典范对应分析对于揭示土壤节肢动物的空间异质性及其与环境因子的相互关系具有理想的效果。

Abstract: In 2008, an ice storm caused extensive damage to the montane evergreen broadleaved forest in Chebaling National Nature Reserve, Guangdong Province, China. To assess the response of soil arthropod diversity and distribution to a gradient of canopy openness following the ice storm, 17 plots, each 400 m~2, were selected within a 2-ha permanent plot. Canopy openness was estimated with hemispherical photography in each plot. We sampled the litter layer and two soil layers (0-10 cm and 10-20 cm) to measure arthropod diversity and soil properties. We used two-way cluster analysis to group sites based on arthropod abundance in the litter layer. We also utilized canonical correspondence analysis to reveal relationships between soil arthropods in the 0-10 cm layer and four environmental variables, i.e., canopy openness (CO), soil organic matter (SOM), electric conductivity (EC), and natural moisture content (NMC). Results showed that abundance, richness and diversity of arthropod communities decreased with depth. A negative association was found between canopy openness and the number of arthropod groups in the litter layer; some arthropod taxa, such as the Oribatida, Prostigmata and Mesostigmata, were found in a wide range of light conditions, whereas the Hymenoptera, Symphyla, Pseudoscorpiones and Lepidoptera larvae may be photophobic. The distribution of arthropods in the 0-10 cm soil layer was closely related to CO, SOM, EC, and NMC on the first and second canonical axes. Hence, a series of changes in canopy structure and soil factors following the ice storm appeared to have affected the composition and distribution of soil arthropod communities. Findings from the present study also indicated that arthropod communities could serve as indicators to characterize the ecosystems they inhabit, thus being particularly suitable for monitoring forest regeneration and successional dynamics following ice storms.
马克思“重新建立个人所有制”思想再析——兼与许崇正教授商榷
柳泽,蒋少华?
天府新论 , 2012,
Abstract: 马克思“重新建立个人所有制”思想是在生产力生产关系辨证运动规律的基础上对资本主义社会以后的社会所有制形式的科学设想,辨证否定资本主义所有制形式是准确理解其科学内涵的关键.高度发达的生产力,全面而充分发展的个人,对私有财产的全面扬弃等,是重新建立个人所有制的历史前提.从本质上看,重新建立个人所有制标志着人与自然、人与人之间矛盾的真正解决,标志着自由人联合体的真正形成.

Abstract: 将从稠油污水中筛选出的3株高效烃类降解菌株HD-1、HD-2和HD-3用于稠油污水处理,研究了单一菌株和混合菌株对原油和COD的去除率。实验结果表明,单一菌株对原油和COD具有很好的去除效果,混合菌株对原油和COD去除效果更加显著。室内模拟实验结果表明,在停留时间为6h时,含油量和COD分别为30mg/L和300mg/L时,经过生物接触氧化处理,出水含油量和COD分别降至1mg/L和50mg/L以下,达到了反渗透膜组件预处理的要求,为稠油污水热采锅炉用水回用提供了理论基础。

Abstract: 在原位式和异位式的模式下,利用生物絮凝技术(Biofloc Technology, BFT)养殖吉富罗非鱼(GIFT Oreochromis niloticus)120 d。罗非鱼原位组(对照组)和异位组(实验组)初始体质量为(19.76±2.44)g和(21.01±1.23)g,初始养殖密度为(2.63±0.33)kg/m3和(2.80±0.17)kg/m3,实验结束实验鱼体质量分别达到(306.21±18.64)g和(338.49±19.35)g,养殖密度分别达到(33.29±0.83)kg/m3和(37.99±2.34)kg/m3。结果表明养殖前期两组中氨氮、亚硝氮均有明显积累,但中后期氨氮和亚硝氮浓度分别维持在3 mg/L和2 mg/L以下,两组硝氮浓度在整个实验过程中一直累积,实验组水质变化较对照组更稳定。两组实验鱼肌肉粗蛋白含量无显著差异。两组实验鱼胃蛋白酶活力同一时期没有显著差异,但是终末活性略低于初始活力;对照组鱼体肠组织中的胰蛋白酶活力在整个养殖期间都高于实验组。两组胃脂肪酶活力和肠脂肪酶活力同一时期没有显著差异。实验通过研究两种生物絮凝模式下吉富罗非鱼养殖效果,为生物絮凝技术在生产实践上的应用和完善提供参考依据。
In in-situ and non-situ modes, new GIFT tilapia (Oreochromis niloticus) was cultured with biofloc technology (BFT) for 120 d. Initial body mass of tilapia was (19.76±2.44) g, (21.01±1.23) g, and initial culture density was (2.63±0.33) kg/m3, (2.80±0.17) kg/m3. At the end of the experiment in situ group (control group) and non-situ group (treatment group),the weight of experimental fish were (306.21±18.64) g, (338.49±19.35) g. The culture density reached (33.29±0.83) kg/m3, (37.99±2.34) kg/m3. Ammonia nitrogen and nitrite nitrogen were accumulated in the early stage, but in the middle and late stages, the concentration of ammonia N was maintained below 3 mg/L and nitriter N maintained below at 2 mg/L. Nitrate nitrogen concentration has been accumulated in the whole experiment. The water quality of the treatment group was more stable than that of the control group. There was no significant difference in crude protein concentration between the two groups. There was no significant difference in stomach protease activity in each period, but the final activity was slightly lower than the initial activity. The trypsin activity in the intestinal tissues of the control group was higher than that in the treatment group during the whole breeding period. There was no significant difference in stomach lipase activity and intestinal lipase activity in the two groups.The experiment provides reference for the application and improvement of biofloc technology in production practice, through studying the effects of two kinds of bioflocculation modes on the production of new GIFT tilapia.

 [PDF]


Advances in Social Sciences (ASS) , 2016, DOI: 10.12677/ASS.2016.51007
Abstract:
民办高校专职辅导员的职业幸福感问题是辅导员职业化建设过程中的关键一环,但社会、学校和个人对辅导员工作的认知和认同仍有待提高。调查显示,云南省民办高校专职辅导员群体的职业幸福感普遍较低,其关键性影响因素则是缺乏合理的管理制度、工作模糊、工作压力大、系统性职业培训的缺失等问题。正确认识云南省民办高校专职辅导员群体的职业幸福感及其关键影响因素,能有的放矢地促进学校制度的完善、增强专职辅导员的归属感和职业幸福感,并最终利于学校管理和未来长远发展。
The professional happiness of the full-time college counselors in civilian-run colleges is a key point of the professionalization of college counselors, but still lacks enough attention and correct identification. Our survey reveals that the counselors group in Yunnan’s civilian-run colleges has a low level of professional happiness, and the important factors giving rise to that are being lack of reasonable management system, job ambiguity, heavy work pressure, being lack of systematic vocational training and so on. A correct understanding of the situation and influence factors of the full-time counselors’ professional happiness in Yunnan’s civilian-run colleges can be beneficial to the improvement of college management institution, and be favor of strengthening the belonging-ness and professional happiness of the counselors as well, which will contribute to the further de-velopment of the civilian-run colleges ultimately.

Abstract: 中国北方沙尘气溶胶的理化特征及其气候效应受到了广泛关注,但现有的研究大都是基于较短时段和典型事件的试验观测。本项研究利用大流量采样器和安德森采样器,对沙坡头地区沙尘气溶胶的质量浓度特征进行了长达3a的监测,获得了该地区沙尘气溶胶的年变化特征,并与背景气象资料和降尘观测结果进行了对比分析;针对典型天气过程的观测结果表明,不同天气条件(背景大气、浮尘、扬沙和沙尘暴)下TSP浓度存在倍数关系和量级的差异,其质量浓度随粒径分布特征也明显不同;两种采样器观测结果的对比分析也表明,局地沙尘释放是沙坡头地区大气气溶胶的主要来源,但在沙尘暴过程中,远源沙尘输送的贡献也不容忽略。

Abstract: 以磷酸氢二氨[(NH4)2HPO4]、四水硝酸钙[Ca(NO3)2·4H2O]和四水硝酸铅[Pb(NO3)2·4H2O]为原料,在200℃水热处理12h制得Ca10-xPbx-HA[x=0~10,Ca-Pb-Ca10(PO4)6(OH)2,Ca-Pb-hydroxyapatite,Ca-Pb-HA]固溶体。通过X射线衍射、化学分析方法以及电子显微镜对Ca-Pb-HA固溶体的晶相、化学组成和形貌进行了分析。利用Rietveld方法对Ca-Pb-HA固溶体进行了结构精修,结果表明晶体结构随铅离子固溶量的增大发生了较大的变化,晶胞参数a和c不随铅离子含量的变化而呈线形变化。在Ca-Pb-HA固溶体中铅离子优先占据M(2)位置。Rietveld分析结果很好地解释了Ca-Pb-HA固溶体结构随铅离子含量的变化规律。
