本文针对用户实际情况建立了一套基于分布式新能源的冷、热、热水三联产的系统。通过对当地太阳能资源以及负荷需求进行分析，对系统的方案进行了合理的设计。并对所需主要设备进行了选型，包括废气/空气源三用热同收机组，吸收式制冷机组，平板太阳能，槽式聚光太阳能以及中温高密度相变蓄热装置。系统主要功能包括三个部分：1)空调夏季制冷、冬季制热；2)动物楼四季供应生活热水；3)冬季制热设备的性能保障。对比分析了已有
本文针对作者单位的GLP动物设施系统设备特点，建立了一套安全、实用、经济、可控、可追溯的社会化技术服务体系；通过对湖北省食品药品安全评价中心GLP动物实验设施中央空调冷热源、净化通风空调、强弱电与送排水、电视监控与门禁、消毒、物流、节能及动物饲养工艺系统设备的社会化维护服务与专业化运行管理模式探讨，并在计划周全、SOP细致、记录完整、实时监督的服务手册指导下，通过近2年的实践检验，该设施系统设备得
环介导等温扩增(loop-mediated iso thermal amplification,LAMP)技术是日本学者Notomi等2000年建立核酸扩增技术,该技术能在恒温条件实现滚环扩增,扩增效率是PCR 10-1000倍,应用3对特异引物组合扩增,敏感性和特异性都比PCR高,与巢式PCR相当,且实验设备要求低,仅需一台恒温水浴锅就可以完成整个试验过程,特别适用于基层检验。另一方面,由于LA
Diatom analyses have been performed on a 1065 cm long Holocene undisturbed and finely laminated sediment sequence from Suminko Lake, Kashubian Lake District,Northern Poland.The absence of human activi
A general mean annual temperature increase has been recorded on the Yutman-Guizhou Plateau of China during the last century and most significantly since 1950s.To understand the response of lake ecosys
The largest array of Thrombolites (a type of Microbialites similar to the Stromatolites) in the world is located in Lake Clifton in Western Australia.Microbialites are believed to be built by a commun
Until now the main methods of water environment monitoring are physical and chemical methods.Although use these methods can measure characteristic and density of the special pollutant,it can only meas
The DNA modified gold nanoparticles (DNA-AuNPs) have been broadly used in the analytic chemistry.However,people found that the assembly efficiency of the DNA molecules on the AuNPs were very important
阿尔兹海默症(Alzheimers disease,AD)是一种常见的神经退行性疾病.它的主要病理特征之一是脑内明显的胞外淀粉样蛋白斑,其主要成分为β-淀粉样蛋白(amyloid β protein,Aβ)[1].研究表明水溶性的Aβ寡聚体有很强的神经毒性,因此水溶性寡聚体己成为诊断与治疗AID的靶标之一,如何特异性地识别寡聚体并中和其毒性也己引起了许多学者的注意.目前已有不少高亲和与特异性的DN
Autophagic lysosome reformation (ALR) plays important role in maintaining lysosome homeostasis.During ALR,lysosomes are reformed by recycling lysosomal components from autolysosomes.The most visible s
