黔中、黔北地区玉米秸秆再利用调查与分析

在贵州,玉米秸秆仅用于作冬贮饲料、燃料和垫圈,甚至就地烧毁,不仅造成了资源浪费,而且又污染了环境。针对黔中、黔北地区玉米秸秆的再利用情况进行了调查与分析,找出黔中、黔北地区玉米秸秆再利用中存在的问题和利用的有效途径,以减少资源浪费和减轻环境污染,实现农业的可持续发展。     

和田绿洲蒸发能力预测的多因素GM(1,3)模型

在灰关联分析的基础上，找出了影响和田绿洲蒸发能力变化的主要影响因子为平均气温与相对湿度。根据灰色GM（1，N）建模原理，对和田绿洲蒸发能力建立了GM（1，3）预测模型，经检验模型预测结果较好，同时也说明了GM（1，N）模型在中长期水文预报中的适用性。     

辽宁新品系绒山羊Hoxc-13基因的结构和分析

本文论述了在研究辽宁新品系绒山羊皮肤上调控绒细度基因时,通过RT-PCR和RACE方法,在皮肤中获得了Hoxc-13启动子1 367bp。此外,本文描述了Hoxc-13基因的分离和特性,并进行比较分析,在控制毛发角蛋白转录方面,Hoxc-13基因在皮肤中可能还有其他的重要功能。     

附子种质资源HPLC指纹图谱的初步研究

为构建生附子药材的HPLC品质指纹图谱,建立附子种质资源品质评价高效准确的鉴定方法,以收集自四川、云南等地的14份附子种质资源和四川江油附子GAP基地的参照药材为材料,采用HPLC方法,在kromasil C18柱,水(6 mmol·L-1SDS、20mmol.L-1NaH2PO4)-甲醇,梯度洗脱,流速0.8 mL·min-1,检测波长240 nm等条件下建立生附子品质指纹图谱。结果表明各份供试样品色谱峰分离良好,符合指纹图谱有关规定,15份供试样品有9个共有峰,与参照药材比较相似度0.90以上的有7批。本研究所构建的指纹图谱可作为生附子药材鉴定和质量控制的参考依据,建立的HPLC方法可作为附子良种选育研究中对种质资源内在品质进行鉴定的有效方法。

以楸树茎段为材料,研究了不同灭菌方法对离体组织培养的影响,结果表明采用1.25g/l多菌灵浸泡30min+酒精棉球擦拭外植体+(400mg/l青霉素+200mg/l链霉素) 浸泡20min+0.1%升汞8min灭菌效果最好.     

杂谷脑河流域河谷区植被及其生物多样性

对岷江上游杂谷脑河流域干旱河谷区典型地段植被及其生物多样性进行了研究。结果表明：岷江上游杂谷脑河流域干旱河谷区植物种类较少，且具有荒漠化半荒漠化性质，阴坡植被明显比阳坡丰富；该区植被及其生物多样性指数在阴坡和阳坡均表现出随海拔升高而增大的趋势；该区域植被恢复宜从阴坡着手。     

冬凤兰非共生萌发和低温离体保存（英文）

[Objective] The aim of the research was to establish asymbiotic germination and low-temperature in vitro conservation technique system of Cymbidium dayanum by using plant tissue culture technique to realize its rapid propagation and long-term conservation in vitro.[Method] With mature seeds of C.dayanum as explants,different media were selected to establish asymbiotic germination technique system.With protocorms as materials,conservation,resumptive proliferation and plant regeneration conditions were selected to establish low-temperature in vitro conservation technique system preliminarily.[Result] Mature seeds of C.dayanum could germinate after cultured 90 days on MS media as well as "Hyponex 1" media.The germination rate reached more than 98%.Protocorms inoculated in "Hyponex 1" media could be conserved continuously at 5 ℃ in dark for more than 18 months and the survival rate could reach 90%.Conserved protocorms could realize resumptive proliferation culture both on 1/2 MS and "Hyponex 1" media.The seedling-strengthening and rooting media were 1/2 MS media.[Conclusion] This research provided practical basis for in vitro conservation and rapid propagation of C.dayanum germplasm resource.     

High-Pressure Iron-Sulfur Compound, Fe3S2, and Melting Relations in the Fe-FeS System

An iron-sulfur compound (Fe3S2) was synthesized at pressures greater than 14 gigapascals in the system Fe-FeS. The formation of Fe3S2 changed the melting relations from a simple binary eutectic system to a binary system with an intermediate compound that melted incongruently. The eutectic temperature in the system at 14 gigapascals was about 400°C lower than that extrapolated from Usselman's data, implying that previous thermal models of Fe-rich planetary cores could overestimate core temperature. If it is found in a meteorite, the Fe3S2 phase could also be used to infer the minimum size of a parent body.
