Abstract: Active sludge was from a pilot-scale synthetic ammonia industrial wastewater treatment plant with a strengthen anoxic-oxic (A/O) technology. The zero order kinetic model was suit for describing shortcut and complete denitrification process.Experimental results showed that shortcut denitrification could reduce 14.1% carbon source consumption and 55.7% denitrification time, respectively, comparing with complete denitrification. The maximum specific denitrification rate was 0.509 g·(g·d)-1 with an initial NO2--N concentration of 36.82 mg·L-1 and pH 7.5. In the industrial practice, it must be avoided pH higher than 9.0 in anoxic zone for industrial treatment. Replication-selective denitrifying bacteria showed a strong adaptability to methanol and ethanol, but showed maladaptation to other small molecular and easily biodegradable organics, such as glucose and acetic acid.

Abstract: TianQin is a proposal for a space-borne detector of gravitational waves in the millihertz frequencies. The experiment relies on a constellation of three drag-free spacecraft orbiting the Earth. Inter-spacecraft laser interferometry is used to monitor the distances between the test masses. The experiment is designed to be capable of detecting a signal with high confidence from a single source of gravitational waves within a few months of observing time. We describe the preliminary mission concept for TianQin, including the candidate source and experimental designs. We present estimates for the major constituents of the experiment's error budget and discuss the project's overall feasibility. Given the current level of technology readiness, we expect TianQin to be flown in the second half of the next decade.

Abstract: 利用ISSR分子标记技术,分析了甘肃省东部地区8个中国沙棘居群的遗传多样性和遗传分化,以及气象因子对它们的影响.共调查了8个居群的240个个体,利用11条引物扩增出165条带.扩增范围集中在300~1 500 bp,其中157个位点表现为多态,占95.76%,分子变异分析(AMOVA)显示,居群内遗传分化程度高,76.5%的变异存在于居群内.基因分化系数(Gst)为0.2418,居群间基因流为1.5675.说明保护沙棘种群的遗传资源应优先考虑种群内个体.经Mantel检验发现,8个居群的地理距离和遗传距离显著相关(r=0.65,P=0.002). 对气象因子与遗传多样性所作的回归分析显示, 中国沙棘开花期间的风速与其遗传多样性呈显著正相关.说明开花期风速和地理距离是沙棘种群遗传多样性的重要影响因子.

Abstract: 1991-1992年,分析了6个光(温)敏核不育系与15个核质互作不育系杂交F_1及部分F_2植株在长日照和短日照条件下的育性表现,结果清楚地表明,有些光敏核不育系能够保持核质互作不育系的雄性不育性,有些光(温)敏核不育系则能够恢复或部分恢复;有些光敏核不育系对某一核质互作不育系具有保持能力,对另一核质互作不育系则具恢复能力;并初步推测光(温)敏核不育基因与核质互作不育基因是独立发生的,当核质互作不育系中细胞质和细胞核的隐性不育基因一起作用时,能够掩盖光(温)敏不育基因及其育性恢复基因的表达.

中国物理快报 , 2009,
Abstract: A torsion balance is constructed to accurately measure the magnetic properties of the real proof mass of the inertial sensor. The magnetic susceptibility and remnant moment of a titanium proof mass are measured in the first experiment, and further improvements and the potential sensitivity are also discussed. This is significant for choosing the material of the proof mass and investigating the magnetic disturbances acting on the proof mass.

Abstract: 采用高频感应熔融、退火结合放电等离子烧结方法制备高锰硅(HMS)化合物MnSi1.70+x(x=0,0.05,0.1,0.15),系统研究了Si含量变化对材料相组成、微结构和热电性能的影响规律.结果表明,当x<0.1时,样品由HMS和贫Si的MnSi金属相两相组成,随着Si含量x的增加,MnSi相相对含量减小;当x=0.1时,所得样品为单相HMS化合物;当x>0.1时,样品由HMS和过量Si两相组成.随着x的增加,由于样品中高电导的金属相MnSi含量逐渐减少,样品的电导率逐渐下降,而Seebeck系数随之增加.室温下样品载流子浓度和有效质量随x增大逐渐减小,而迁移率逐渐增加.MnSi和Si杂相与HMS相比均为高热导相,因此当x=0.1时,由于样品为单相HMS,从而表现出最低热导率和最高ZT值.MnSi1.80样品在800 K时热导率最小值达到2.25 W ·m-1K-1,并在850 K处获得最大ZT值(0.45).

Abstract: Based on designing an intelligent self-timer system for the Digital Camera, a simple and effective approach was given to detect and locate the human body based on the still background. The background model was built based on the difference between real-timer image and reference image, in terms of which foreground objects were segmented. Then shadows were removed according to the contained angle of color vector. Finally threshold of the projection was used to extract and locate the human body. This algorithm can meet the object-tracking requirements of self-timer with low computation and good adaotability.
