Experiment Research on Leachate Treatment of Sanitary Landfill for Municipal Solid Waste

It is difficult to treat landfill leachate in China.Traditional biologic method and physical method always have high expenses,or cann''t reach the discharge standards.The authors use a new biologic method to treat landfill leachate,which is the Wood_microbial System from Japan.The system to be digested by 3 aeration tanks and 1 reaction tank.The comparison combine processed wool_dust broken pieces with the certain grain degree size were throw in the tanks.Dirty and organic matter are in the digest tanks through the aeration reaction and aneration reaction repeatedly.In this experiment the speed of wastewater discharge and oxygen supply has been changed, and the change of biologic system and the effect of pollutant are removed. The optimal treatment condition can be found.The experiment shows that the system has a good result,special for nitrogenous.The BOD is average to do away with the rate to amount to 90%,almost reach the second class or third class for leachate standard.But BOD loading should be not beyond 4 kg/(m 3.d),othrwise,the system will not operate in normally.

Effect of Nitrogen Rate and Stubble Height on Dry Matter Yield,Crude Protein Content and Crude Protein Yield of a Sorghum–Sudangrass Hybrid[Sorghum bicolor (L.) Moench × Sorghum sudanense (Piper) Stapf.] in the Three‐Cutting System

In this study, the effects of nitrogen (N) rate (60, 120, 180 and 240 kg N ha^?1 applied in three equal dressings at seeding and after the first and second cuttings) and stubble height (7, 14 and 21 cm) on the dry matter (DM) yield, crude protein (CP) content, and CP yield of a sorghum–sudangrass hybrid [Sorghum bicolor (L.) Moench × Sorghum sudanense (Piper) Stapf., cv. Pioneer 988] in the three‐cut system was investigated. The N rate had no significant effect in the first and third cuttings, but in the second cutting DM yields increased significantly with increase in N rate. The highest yield of 9.1 t ha^?1 was obtained with 80 kg N ha^?1 for the average of 2 years at the second cutting, but no significant difference was found among the 40, 60 and 80 kg N ha^?1 rates. CP content and yield were not significantly affected by N rate at the first and third cuttings, but CP content and yield were significantly affected by application of N at the second cutting. Stubble height had a significant effect on CP content at the third cutting. However, it had no significant effect on CP content at the first and second cuttings. Stubble height had a significant effect on the CP yield at the first cutting, but no significant effect on CP yield at the second and third cuttings.     

互联网环境下的暖通CAD组件模块的开发方法研究

针对单机环境下暖通CAD软件重复开发量大、开发周期长等现状，提出了基于互联网环境的三层体系结构及其开发的通用环境，即整个暖通CAD系统被分为不同逻辑块，开发和管理的工作向服务器方转移，从而使分布处理数据成为可能，基于组件的软件开发是互联网环境中应用软件的主要开发方式，以构架为组装蓝图，以可重用组件为组装预制块，支持组装式软件重用，从而克服人力和物力的浪费，进而为了重用暖通CAD已开发出的功能模块，给出组件逆向工程的开发方法、组装流程和组件管理过程。     

氮素用量和密度对玉米营养体产量的影响

研究了氮素施用量和密度对玉米营养体产量的影响。结果表明，增施氮素和增加种植密度对玉米营养体产量有显著的增产效应，在密度为15万株／hm^2，施氮237kg/hm^2时，玉米营养体产量最高，为32584.7kg/hm^2，比常规种植密度9万株/hm^2增产26％。玉米营养体产量乳熟期最大，适宜收割期宜在灌浆期。营养体生产较籽实生产收获期提前了50d，利用玉米营养体收获后的生长余季（8月1日－10月20日）生产毛叶苕子营养体，二者合计生产绿色营养体3．88万kg/hm^2，粗蛋白5638．51kg/hm^2，分别是籽实生产的1．5，3．77倍。光，热，水生产效率较籽实生产提高了47．8％。     

藏系绵羊随机扩增多态性DNA最佳反应体系的研究

以高原型藏羊的基因组DNA为模板，通过对RAPD反应体系中的各种参数进行优化试验，建立了适宜于藏系绵羊RAPD分析的最佳反应体系：在PE2400型DNA扩增仪的25μL反应体系中，模板DNA的量为60－120ng，引物量为4－8pmol，Mg^2 浓度为2.0mM，Taq DNA聚合酶为1－2.5U,dNTP浓度为150－200μM;94℃预变性3分钟后35次循环的参数设定为：94℃1分钟，36℃1分钟，72℃2.5分钟，最后72℃延伸10分钟，利用这些条件对藏系绵羊的基因组DNA进行RAPD分析，其结果的重复性和可靠性大为提高。     

试论灰色系统关联度分析法在生物科学研究中应用的合适性

灰色系统关联度分析法的主要研究对象是社会经济等非技术的抽象系统。近年来，在生物科学领域如畜牧、兽医、草原等技术性强和具体系统的科学研究中，发现有应用该法分析其试验数据的论文。经研究核实，应用该法分析生物科学研究的数据，似欠合适。这可能是由于该方法本身有不足处，或由于论文作者误用该法。特提出供读者与学者讨论与研究。     

关于我国设立刑事证据开示制度的思考
