Abstract:
首次采用气象色谱法,开展两个膏桐新品种——多花膏桐和皱叶黑膏桐籽油得脂肪酸组成分析;同时,又以竹碳基固体酸为催化剂,以膏桐新品种(包括多花品种和皱叶黑品种)籽油为原料,探讨竹碳基固体酸在膏桐籽油酯化反应中的催化效应,测定了不同膏桐新品种籽油炼制生物柴油的效率。测定结果表明,膏桐新品种籽油脂肪酸的组成重要是棕榈酸、棕榈油酸、硬脂酸、油酸和油酸,品种间的差异主要体现在脂肪酸组成的相对比例的变化上,因此可作为膏桐植物种群进化的评价依据;膏桐新品种籽油炼制生物柴油的效率分别为多花膏桐89.68%、皱叶膏桐86.50%、西双版纳(勐仑)地方品种87.12%,其主要成分是棕榈酸甲酯、油酸甲酯和亚油酸甲酯。品种间的差异亦主要体现在脂肪酸甲酯组成的相对比例的变化上。
Analysis of compounds of high-acid oil extracted with machine from two new jatropha cultivar seed had been carried out by Gas Chromatography (GC) since 2010. At the same time, using bamboo carbon base solid acid as a catalyst and the new jatropha cultivars seed oils as raw materials, impact factors of esterification reaction had been investigated, and esterification rate of the jatropha cultivars seed oils and main fatty acid compounds were also determined by GC. The results showed that the jatropha cultivars oils are mainly composition of palmitic acid, palmiticoleic acid, stearic, oleic and linoleic. Differences between both the seed oils of the different jatropha cultivars found mainly expression in the relative ratio of different fatty acids, indicating that a significant change in the relative ratio of the different fatty acids can be considered as an evolutionary evidence of jatropha population. On the basis of jatropha seed oils with high-acid value, esterification of the new jatropha seed oils was carried out using bamboo carbon base solid acid as a catalyst, and had achieved esterification rates of 86.5% - 89.7%. The products of the esterification are mainly composed of palmitic acid methyl, oleic methyl and linoleic methyl, and difference between these jatropha cultivars also found expression in the relative ratio of different fatty acid methyls. Black winkle-leafed jatropha cultivar is distinctive to the other two cultivars, which in the front rank of the fatty acid methyls is linoleic methyl that is the highest (42%) followed by oleic methyl (36%) and stearic methyl (16%), whist rank of other two cultivars is oleic methyl (42%) that is highest followed by linoleic methyl (36%) and stearic methyl (16%).

Abstract: 随着现代计算机科学技术的不断发展,labview图形编程自2011年以来,元江干热河谷进行了巴西油藤的引种试验。试验结果表明,与先前西双版纳引进的秘鲁油藤(Plukenetia volubilis cv. peruvian, PVP)比较,巴西油藤(Plukenetia volubilis var. brazilian, PVB)有较强的适应性和较高的生产潜力。二者相比,巴西油藤(PVB)对元江干热河谷具有比较好的适应性和生物学特异性。其特异性表现为不易染病,雌花花柱比较短,种籽粒小、皮薄,种子含油率为35.4%,高于秘鲁油藤(34.1%) 1.4个百分点;通过机械压榨,种子油的得率为30%。小区试验3年生时种子亩产量为88.5 kg,折合每公顷1327.5 kg/ha,可产精油367.1 kg/ha。从这些数据来看,巴西油藤在云南干热河谷区生物产业发展中有良好的应用前景。
Since 2011, an introduction test of Plukenetia volubilis var. brazilian (PVB) has been carried out in arid-hot valley of Yuanjiang, Yunnan. The results showed that compared with Plukenetia volubilis var. peruvian (PVP) introduced in Xishuangbanna previously, PVB has a strong adaptability and high production performance. Its advantages lie in not infected, style short, thin shell, small grain, high rates of seed oil. According to determination, PVB seed oil content (35.4%) was slightly higher than PVP (34.1%), and obtained seed oil content of 30% by mechanical pressing and on small field test, seed yield reached 1327.5 kg/ha and oil yield of 367.1 kg/ha at 3-year-old growth. It is suggested that PVB has a good perspective for bio-industry development in the dry-hot valley of Yunnan.

Abstract: 2012~2015期间,在云南西双版纳和元江那唐山南亚热带高档油料植物试验基地,我们开展了皱叶黑膏桐与美藤果(Inca Peanut)伴生种植的试验。本项试验的目旨在利用膏桐活体根系释放的挥发性化感物质对实验区土壤有害生物进行实时生物防控,以保证美藤果植株健康地生长、开花和结果,实现美藤果引种开发的优质高产。试验结果表明,采用皱叶黑膏桐伴生种植以后,在美藤果种植试验区内线虫、白蚁和病原微生物的危害已明显低于美藤果单一种植区。与此同时在伴生种植区内,美藤果植株生长速率、分枝数量、开花结果物候,雌花比例、坐果率等指标,也得到了明显提高。
During 2012-2015 years, new Jatropha varieties and Inca peanut planting collocation experiment had been conducted on the south subtropical high-grade oil planting test bases of Xishuangbanna and Yuanjiang. This study aimed at using volatile components released by the living roots of Ja-tropha curcas to prevent or/and control nematode, termites and other soil pests, to guarantee healthy growth, flowering and fruiting of Inca peanut plants, and to realize high yield and good quality of Inca peanut production. Experimental results show that after Inca peanut accompanied planting with wrinkled-leaf jatropha, in the planting test area the nematode and termite’s dangers had been greatly lower than those of Inca peanut monoplanting. At the same time, the indicators such as plant growth rate, number of branches, phenology of flowering and fruiting, the proportion of female flowers, fruit setting rate, have also been significantly improved.

Abstract: 应用多组态Dirac-Fock(MCDF)方法,对Xe10+离子进行了理论计算,获得了跃迁波长和概率等数据.通过逐步引入4dn—5pn(n=1, 2, 3)电子相关的相互作用组态,重点研究了电子相关效应对4d8—4d75p跃迁系跃迁概率的影响.结果显示电子相关效应显著,表明了欲得到精确的4d8—4d75p的振子强度(跃迁概率)数据,理论计算中至少要包括到4d2—5p2的电子相关组态的影响.与实验测得的跃迁波长比较发现,理论结果与之有着较好的一致性;同时理论跃迁概率在两种规范下的结果符合得相当精确,显示了计算结果的可靠性.

Abstract: ?选择内蒙古赤峰市敖汉旗内水平梯田为研究对象,对不同水平梯田进行采样,分析了梯田土壤有机碳含量的垂直分布特征,以及地形因子和人类活动对其影响。结果表明:研究区梯田1m深土壤剖面有机碳含量在0.87~10.25g·kg-1,平均含量为5.91g·kg-1。不同土层间有机碳含量存在明显差异,有机碳含量随着土壤深度的增加而降低;表层土壤有机碳平均碳含量为7.54g·kg-1,分别是中层和底层土壤有机碳含量的1.32倍和1.67倍。各层土壤有机碳含量随坡位的变化均表现为上坡位<中坡位<下坡位;不同坡向上土壤有机碳平均含量表现为阴坡>半阴坡>半阳坡>阳坡,且坡位和坡向对土壤有机碳的影响均存在显著差异(p<0.05)。人为因素对梯田土壤有机碳含量的影响主要体现在不同的耕作制度和管护措施上,秸秆还田、免耕等措施有助于提高土壤有机碳含量。?
降雨入渗条件下非饱和土朗肯土压力分析

岩土力学 , 2013,
Abstract: 传统的土压力分析仅考虑了土体饱和强度对土压力产生的贡献,忽略了基质吸力及其变化对土压力的影响。运用非饱和土有效应力原理和饱和土朗肯土压力公式推导了非饱和土朗肯土压力公式,结合iverson降雨入渗解析解,推导出降雨入渗条件下非饱和土压力公式。该公式将降雨入渗时的非饱和土压力表示为时间和深度的函数,更符合实际情况。研究结果表明:采用该方法计算得到的土压力值相对于传统计算结果偏大,作用点偏高;此外,随着降雨的发生、入渗和停止,主动土压力呈现“减小-增大-减小-稳定”趋势,被动土压力呈现“增大-减小-增大-稳定”趋势,该现象由降雨过程中基质吸力改变所致。由该公式获得的土压力分布及变化规律可用于挡土工程结构的设计。
