Abstract: 从上世纪开始,人类逐渐进入了以煤、石油、天然气等化石能源为主的年代.进入21世纪,石油、天然气价格很不稳定,事实上已经把人们推进到3种能源共存,即化石能源、可再生能源和核裂变能源共存的年代.在这个时代中,各个国家需要针对本国具体情况,开展能源的过程工程研究,解决石油和天然气价格飞涨的迫切问题.到本世纪后期或下世纪初期,人类将会逐步进入到核裂变能源的时代.
Effects of correlations between the real and imaginary parts of quantum noise on intensity fluctuation for a saturation laser model

Li Yue-Hong,

物理学报 , 2008,
Abstract: This paper studies the effects of cross-correlations between the real and imaginary parts of quantum noise on the laser intensity in a saturation laser model. It derives the analytic expressions of the intensity correlation function ${C(\tau)}$ and the associated relaxation time ${T({C})}$ in the case of a stable locked phase resulting from the cross-correlation ${\lambda_q}$ between the real and imaginary parts of quantum noise. Based on numerical computations it finds that the presence of cross correlations between the real and imaginary parts of quantum noise slow down the decay of intensity fluctuation, i.e., it causes the increase of intensity fluctuation.

Abstract: 我国是一个石油资源紧缺的发展中国家,石油供给高度依赖于世界石油市场.世界原油资源的重质化和对轻质产品需求的增加,使重质石油烃利用技术成为我国能源和石化工业的一个重要课题.现有的重质石油烃利用技术中,减粘裂化、焦化、催化裂化和加氢转化仍然是最主要的技术手段.同时,气化和裂解制烯烃也显示出良好的技术潜力.本工作提出的重质石油烃气化-裂解集成工艺利用燃烧裂解结焦为气化和裂解过程提供热量,同时产出合成气和部分低碳烯烃.模拟研究显示,通过调整O2和水蒸汽流量可实现对气化-裂解温度的控制,在近零焦炭添加量的情况下可同时获得合成气和低碳烯烃,可在控制反应停留时间的条件下获得产物中烯烃的最大组成. 质化和对轻质产品需求的增加,使重质石油烃利用技术成为我国能源和石化工业的一个重要课题.现有的重质石油烃利用技术中,减粘裂化、焦化、催化裂化和加氢转化仍然是最主要的技术手段.同时,气化和裂解制烯烃也显示出良好的技术潜力.本工作提出的重质石油烃气化-裂解集成工艺利用燃烧裂解结焦为气化和裂解过程提供热量,同时产出合成气和部分低碳烯烃.模拟研究显示,通过调整O2和水蒸汽流量可实现对气化-裂解温度的控制,在近零焦炭添加量的情况下 同时获得合成气和低碳烯烃,可在控制反应停留时间的条件下获得产物中烯烃的最大组成.

Abstract: 在脂溶性化感物质的生物检测中,常规方法是使用有机溶剂对化感物质进行助溶,此法本身会对受体植物产生为害,并且不能准确定量.本研究结合药剂学理论,将动物和细胞实验中常用的增溶剂泊洛沙姆(F-68)应用于脂溶性化感物质的生物检测,用泊洛沙姆对香草醛和阿魏酸两种化感物质进行增溶,以乙醇助溶为对照,比较两种方法的化感物质活性.结果表明,化感物质用泊洛沙姆增溶后,形成的溶液是一个稳定的体系,试验过程中浓度不会发生变化,可准确定量考察化感物质的活性,同时泊洛沙姆对受体植物不产生影响.乙醇助溶处理中,或由于乙醇不易完全挥发,因乙醇的存在而对受体植物产生影响,表现为化感物质活性的加强;或随乙醇的挥发,化感物质以晶体析出,表现为化感物质活性的减弱,不能准确定量考察化感物质的活性.

Abstract: 在有关化感物质的研究中,由于一些观念和实验方法的限制,对于脂溶性物质在自然生态环境中是否有化感作用存在争议.在化感物质的生物检测中,脂溶性成分的实验方法比较混乱,并存在很多问题,直接影响到实验的准确性和有效性,不能客观科学地进行定性及定量测定.植物的化感作用是在一个复杂的生态体系中发生的,不应主观排除脂溶性物质在自然界中的化感作用,尤其是现在化感作用机理研究越来越成为研究的热点和重点,要阐明化感作用的分子化学、酶调控和基因调节机制,迫切需要建立一个目标植物全成分化感活性筛选的基础平台,并建立定量化感活性生物检测方法.

Abstract: By using ecological footprint(EF)model,the sustainable development status of eco-economic system in Shanxi Province is analyzed.The results show that the ecological footprint of Shanxi Province is beyond the available ecological capacity(AEC),and runs the'ecological deficit'(ED).The proportion of fossil energy ecological footprint is very higher(79%) in total ecological footprint.The efficiency of biological resources usage is very lower.Therefore,Shanxi must change its traditional highconsumed development model,and establish a production and consumed system of resource-saving.
