Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Gaoya dianqi, 1958 1959年国家要求发电设备的生产比1958年猛增十倍多,同时要求掌握330千伏級的高电气設备的制造技术。要完成这样的艰巨的任务不是一般的計划、措施所能保证的,必须解放思想,打破迷信,发动群众研究新结构,研究新工艺,独創新办法,利用土办法大干巧干才行。 产品是我們生产的对象,一切生产活动是为完成产品品种和数量,提高产品质量和降低成本而进行的。所以产品发展方向和产品结构型式是生产厂的一个根本性的问题。

A Study on the Technology Transfer Efficiency from FDI and International Competitiveness of Auto Industry in China [PDF]
, 2007 汽车产业在一国国民经济中的重要地位不言而喻。在我国，汽车产业已从建国初期基础最薄弱的产业之一成长为最具增长潜力的支柱产业，也从入世之前国家高度保护的产业转变为入世之后面临市场竞争最为激烈的产业。当市场的大门渐渐向外商打开，我国汽车产业的国际竞争力问题成为业界最为关注的焦点之一。 作为技术密集型的汽车产业，技术水平是产业国际竞争力的重要体现。改革开放以来，我国的汽车产业在“市场换技术”的引资政策指导下，逐渐开始了利用FDI来提升产业技术实力的发展模式，汽车企业逐步走入合资合作的发展道路 ...

The analysis of decalin pyrolysis property under supercritical conditions(十氢萘的超临界裂解性能分析)
Zhejiang Daxue xuebao. Lixue ban, 2014 以十氢萘为吸热型碳氢燃料的模型化合物，研究其在550~610 ℃和0. 1~3. 5 MPa条件下的热裂解过程. 实验表明：不同温度（特别是相对较高的590和610 ℃）下，十氢萘在0. 1~2. 0 MPa压力下的转化率增加较为显著；十氢萘热裂解的主要气体产物有甲烷、乙烷、乙烯、丙烷、丙烯和碳原子数大于3的组分(C3+)等；在相同温度条件下，甲烷、乙烯的含量随压力增加而降低；乙烷、丙烷、丙烯和C3+的含量随压力增加而增加.裂解的气相产物中烯烃含量随温度升高而降低.液相产物主要包括环戊烷类、环戊烯类 ...
