Plant flowering and breeding characteristics are important for us to understand the reproduction of plant populations. In this paper, we studied the reproduction characteristics of Jatropha curcas in Yuanjiang County （23°36＇1＇4, 101°00＇E）, Yunnan Province. The plant produces flowers in dichasial inflorescences. Normally, the flowers are unisexual, and male and female flowers are produced in the same inflorescence. Only a few male flowers are produced in an inflorescence, and fruits are produced only through pollination between different flowers from the same or different plants. By the treatments of emasculation, bagging and artificial pollination in this experiment, there were few but same fruit set ratios when the inflorescences were emasculated, bagged, or bagged with net, except artificial pollination treatments, which showed that Jatropha curcas could produce fruit through apomixis but not wind pollination. When the inflorescences were unbagged, unemasculated and with free pollination treatments, or bagged, emasculated and with artificial cross-pollination treatments, or unbagged, emasculated and with free pollination treatments, there were many fruits produced. It showed that Jatropha curcas shows outcrossing, is self-compatible, and demanding for pollinators. Normally, the male flowers open first and a few flowers bloom in one day in a raceme. These flowers last a long time in bloom. However, a large number of female flowers open from the third to the fifth day, with some female flowers opening first in a few raceme. This shows a tendency to promote xenogamy and minimize geitonogamy.

针对闸坝接头段粘土心墙质量不合格、存在大量裂缝等问题,拟采用充填式灌浆法进行处理,但充填式灌浆试验结果表明:灌浆压力太小,不能灌进浆液。根据闸坝接头段粘土心墙中有2道刺墙、坝基为红色砂岩、溢洪道左侧闸墙等特殊情况,通过白氏“孔底注浆、全孔灌注”劈裂式灌浆的反复试验,表明在常规灌浆压力条件下,对坝体粘土心墙中下部段亦无法灌进浆液;在加强各项观测工作,严格控制坝顶劈裂缝某点最大宽度,使之等于4cm(规范规定为3cm之内),且回弹比大于80%的条件下,进行了大幅度提高灌浆压力的试验,最终确定中部灌浆段施工灌浆压力为0.15～0.23MPa,下部灌浆段为0.25～0.40MPa。结果表明,灌浆效果很好。其一,灌浆1年半后,所灌浆液充填、固结较好,且与周边土体胶结较好,灌浆后粘土心墙质量有所改善;其二,灌浆后至今7年多,经多次洪水考验,闸坝接头段无异常。

在对望花亭水库既有土坝坝基大理岩灌浆过程中发现,存在劈裂坝体及坝顶出现劈裂缝、坝顶或坝坡冒浆等异常劈裂现象,该现象既不同于白氏劈裂式灌浆法,也和章氏劈裂式灌浆法不同,是在对坝基灌浆过程中形成的一种新的衍生的劈裂灌浆现象。考虑到对坝基所用的灌浆材料为水泥浆液,并且凝结后在坝体内形成的结石体改变了既有土坝的均质性,因此,人们总是担心这种坝基灌浆方法是否会对坝体构成新的隐患。在介绍传统劈裂式灌浆方法的基础上,对新的衍生的劈裂灌浆现象与章氏灌浆法的灌浆目的、出浆位置、灌浆材料、帷幕形态、坝体变形以及坝体稳定性计算等方面进行了简单的对比与分析。建议重点研究这种新的衍生的劈裂灌浆现象劈裂坝体后所形成的结石体与坝体土的结合程度、结石体的形态、结石体与坝体土的变形状况、结石体对坝体结构安全性及渗流安全性的影响程度及灌浆机理等,这不仅有利于灌浆实践活动,也会进一步促进劈裂灌浆理论的发展。

由于白氏法及章氏法灌浆技术中的护壁管深浅不同,从而使初始劈裂坝体位置也不相同,必然对坝体的帷幕形态、灌浆起始劈裂点、浆液运动规律和灌浆机理等产生影响。白氏法的帷幕形态可归纳为纵向、横向或斜向及水平向3 类,章氏法的帷幕形态可归纳为纵向、横向或斜向、水平向、交叉状及准桩凝固体5 类。但帷幕形态差异较大,如白氏法的纵向帷幕多中间厚上下窄,章氏法的纵向帷幕则为下宽上窄,这是由于灌浆起始劈裂点及浆液运动规律不同造成的。白氏法的起始劈裂点是随机的,而章氏法的起始劈裂点可人为进行控制。白氏法的浆液运动规律可概化为点(随机劈裂点)–线(钻孔)–面(沿坝轴线水平发展)的物理模型,而章氏法的浆液运动规律可概化为点(孔底0.1～0.5 m 处)–面(沿坝轴线呈放射状发展)的物理模型。白氏法的灌浆原理、灌浆机理研究虽相对较为成熟并有规范可循,但灌浆实践不断超越规范规定的范围。总体来说章氏法仍沿用白氏法的原理、灌浆机理和规范,是否合适尚值得商榷。为了解决白氏法坝体下部帷幕较薄或不能灌及的问题,并为章氏法建立理论框架,特提出了修订现行土坝坝体灌浆技术规范的建议。

To construct the Agricultural Scientific and Technical Information Core Metadata （ASTICM） standard and its expanding principles, and to develop a register system based on ASTICM, the policy and methods of DC （Dublin Core） and SDBCM （Scientific Database Core Metadata） were studied. The construction of ASTICM has started from the proposed elements of the DCMI （Dublin Core Metadata Initiative）, and has expanded the DC and SDBCM with related expanding principles. ASTICM finally includes 75 metadata elements, five expanded principles, and seven application profile creation methods. According to the requirement analysis of a large number of users of agricultural information, a register system based on ASTICM was developed. The ASTICM standard framework and its register system supported the search, sharing, integration exchange and other applications, effectively.

Effect of Abiotic Factors on the Mercury Reduction Process by Humic Acids in Aqueous Systems

引用

Pedosphere 2014年第1期24卷 125-136页

作者： JIANG Tao WEI Shi-Qiang D.C.FLANAGAN LI Meng-Jie LI Xue-Mei WANG Qiang luo chang College of Resources and Environment Department of Environment Science and EngineeringSouthwest University Chongqing Key Laboratory of Agricultural Resources and Environment USDA-Agricultural Research Service National Soil Erosion Research Laboratory

As a global pollutant process, the reduction of mercury （Hg） is especially important. One pathway is through an abiotic reduction with humic acids （HAs）, which is controlled by different factors, including initial Hg and HA concentrations, pH, temperature and light. In this study, three humic acids were selected to illustrate the Hg2＋ abiotic reduction mechanisms by HAs, and to identify the key limiting factors for reduction rates and amounts. In addition, the initial status of the HAs as a solid or in an aqueous solution were also compared, to help explain why HAs show different dominant characteristics （e.g. complexation or reduction） in the reaction process with Hg. Results indicated that HAs were able to reduce Hg abiotically. Higher initial Hg, higher HA concentrations and either high （8.1） or low （3.6） solution pH decreased the HA reduction capacity. In addition, Hg~ production rates increased with increasing temperature, and the same trend was observed with light exposure. Humic acids added as an aqueous solution resulted in significantly greater HgO production than addition as a bulk solid. Finally, the Hg reduction rate and capacity varied significantly （P 〈 0.05） with HAs from different sources. These findings helped to explain why HAs showed different dominant characteristics （e.g. complexation or reduction） in the reaction process with of Hg2＋ reduction, which indicated that humic substances in sink or a source for Hg. Hg, and evidentially demonstrated the existence of a possible pathway natural environments, especially in water bodies, could act either as a
