Abstract: 通过对保护地栽培条件下不同连作年限西瓜土壤的调查分析,结果表明:随着西瓜连作年限的延长,土壤中速效磷、速效钾的含量迅速上升,土壤次生盐渍化加剧,土壤呈现酸化的趋势;土壤重金属元素中CuZnAsCr的污染逐步加重;随着连作年限的增加,土壤中西瓜枯萎病菌尖孢镰刀菌数量显著上升。
Through the soil investigation and analysis of different continuous cropping years under protected cultivation conditions of watermelon, the results show the content of available phosphorus and available potassium in soil has increased rapidly with the extension of watermelon continuous cropping years, the secondary salinization of soil is growing in intensity, and soil presents the acidification trends. The pollution of soil heavy metal elements (Cu and Zn, As, Cr) aggravated gradually. Along with the increasing years of continuous cropping, the number of wilt pathogen (Fusarium oxysporum) in soil increased significantly.

Abstract:
为有效提高菇渣废弃物的无害化处置效率,进行了发酵菌剂的引选与无害化处置工艺优化研究,结果表明,菇渣中添加30%比例的牛粪或菇渣中添加10%以上的牛粪及3‰复合菌剂均能大大促进菇渣堆肥升温腐熟发酵过程,缩短物料无害化处置周期,随着处理时间的延长,物料pH表现出先上升后逐步下降的趋势。试验中香菇渣物料的发芽指数在无害化处理5天以后均达到了50%以上的安全范围。研究结论证明通过调节菇渣物料C/N及添加复合菌剂可以显著提高菇渣废弃物的无害化处置效率。
To improve the efficiency of harmless disposal of the mushroom residue, the screening of fermen-tation agent and the research on optimization of harmless disposal technology were carried out. The results showed that adding 30% proportion of cow dung to mushroom residue or adding 10% cow dung with 3‰ compound agent can greatly increase the temperature of mushroom residue compost, promote fermentation and shorten the disposal cycle. With the extension of processing, the pH of material rise in the early time and then decline gradually. The germination index of mu-shroom residue reached more than 50% of the safety range at 5 days after innocent treatment. It proved that adjusting the C/N of mushroom residue and adding compound agent can significantly improve the efficiency of harmless disposal.

Abstract:

针对淳安县废弃山核桃蒲壳资源丰富但又缺乏合适利用技术的难题,尝试将山核桃蒲壳加工用作兰花栽培基质。结果表明,不同替代比率的山核桃蒲壳基质对兰花的栽培效果均明显优于对照(纯松鳞基质),显著增加了兰花根系和新芽生长,增加兰花叶片的长度和宽度。
With the increasing pecan plantations in Chun’an County, Zhejiang, China, there are annually great quantities of pecan shells as waste materials. In this study, we try to utilize the pecan shells as the culture medium for orchid cultivation. The results showed that through the pecan shell-based culture medium, the orchids displayed a better growth of roots and sprouts with the longer and wider leaves, compared with those grown in other culture media.

降解偶氮染料AO7的研究:动力学及反应途径

环境科学 , 2010,
Abstract: 紫外光分解过硫酸盐(S2O2-8)是一种新型的高级氧化技术,可以产生强氧化性的硫酸根自由基(SO·-4).以偶氮染料AO7为目标污染物,重点研究了反应体系氧化剂K2S2O8浓度、溶液初始pH值和无机阴离子(H2PO-4、HCO-3、NO-3和Cl-)对反应体系的影响.结果表明,AO7的降解遵循准一级动力学,当AO7初始浓度为0.14mmol/L时,最佳的氧化剂K2S2O8与污染物AO7的摩尔比为20.pH值对UV/K2S2O8体系降解AO7的反应速率影响较大,增大pH有利于SO·-4转化为·OH.溶液中的无机离子对反应体系有一定的抑制作用.采用GC/MS分析了UV/K2S2O8体系降解AO7的主要中间产物(萘酚、1,2-苯并吡喃酮、邻苯二甲酸),并根据中间产物的分析推测了降解途径.
真核基因转录激活的多位点协同调控
文?,王进?,黄启,郑伟娟?,华子
生物化学与生物物理进展 , 2002,
Abstract: 真核基因的转录激活具有协同性的特征,表现为多个转录调控位点的共同作用效果大于每个位点单独作用之和,受多个位点调控的基因转录呈s型曲线.多个激活蛋白之间的相互作用、激活蛋白与各dna位点的协同结合以及激活蛋白与转录机器的协同作用,三种途径都对协同性转录激活行为产生影响.协同性转录激活的本质是多个结合在调控位点上的激活蛋白之间直接或间接的相互作用.多位点的协同转录调控机制有助于理解生物的多种调控过程和建立基因调控网络.

Abstract: A Ge/Si(001) island multilayer structure is investigated by double crystal X-ray diffraction,transmission electron microscopy,and atomic force microscopy.We fit the satellite peaks in the rocking curve by two Lorentz lineshapes,which originate from the wetting layer region and the island region.Then from the ratio of the thicknesses of the Si and Ge (GeSi) layers as determined by TEM,the Ge compositions of the wetting layer and islands are estimated to be about 0.51 and 0.67,respectively,according to the positions of the fitted peaks.This proves to be a relatively simple way to investigate the Ge/Si (001) island multilayer structure.

Abstract: The effect of substrate structure on the performance of a spiral inductor is investigated with the 3D electromagnetic simulator HFSS.With variations in the substrate structure including substrate conductivity,permittivity,and thickness of the dielectric layer, the performance of the inductors is analyzed in detail.The simulation results indicate that the performance of the spiral inductor can be improved by lowering the conductivity of the substrate,increasing the thickness of the dielectric layer,and using a low k dielectric layer.In the mean time,some "design rules" are summarized form the results of this study.

Abstract: 以叶菜类蔬菜菠菜、大白菜、生菜、香菜、芥菜和雪菜为研究对象,利用海藻固体碘肥和海藻液体碘肥作为外源碘,在露天和大棚栽培条件下进行蔬菜植物碘强化的田间试验,通过分析蔬菜对碘吸收量的动态变化和碘在蔬菜各器官的分布和分配状况,研究了叶菜类蔬菜对外源碘的吸收与积累特征.结果表明,供试叶菜可食部分中碘的含量随着外源碘添加量的增加而增加;随着取样时间的延后,叶菜可食部分中碘的含量呈现出下降的趋势;喷施液体碘肥比土施固体碘肥更有利于叶菜对碘的吸收和积累,前者使吸收的碘大部分积累在叶面,后者则大部分积累在根部.
