A solution of atrazine in a TiO_(2)suspension,an endocrine disruptor in natural water,was tentatively treated by microwave-assisted photocatalytic *** effects of mannitol,oxygen,humic acid,and hydrogen dioxide on the photodegradation rate were *** results could be deduced as follows:the photocatalytic degradation of atrazine fits the pseudo-first-order kinetic well with k=0.0328 s–1,and·OH was identified as the dominant *** of atrazine was hindered in the presence of humic acid,and the retardation effect increased as the concentration of humic acid increased.H_(2)O_(2)displayed a significant negative influence on atrazine photocatalysis *** on intermediates identified with gas chromatography-mass spectrometry(GC-MS)and Liquid chromatography-mass spectrometry(LC-MS/MS)techniques,the main degradation routes of atrazine are proposed.

Optical heterodyne detection using 500 MHz phase modulation was combined with the Zeeman modulation-magnetic rotation spectroscopy (ZM-MRS) to form a new spectroscopic technique, which effectively reduced the amplitude fluctuation from laser source and greatly improved the signal-to-noise ratio in the detection of transient molecules.

中美贸易“再平衡”:路径与前景

外交评论（外交学院学报） 2010年第2期27卷 15-21页

奥巴马政府将美国经济"再平衡"作为摆脱当前经济危机并重塑美国经济增长基础的一项重要内容来看待,并就此采取了一系列政策措施,其核心内容就是要减少美国消费和进口,促进投资和出口。中国与美国之间的贸易失衡被认为是美国经常账户失... 详细信息

奥巴马政府将美国经济"再平衡"作为摆脱当前经济危机并重塑美国经济增长基础的一项重要内容来看待,并就此采取了一系列政策措施,其核心内容就是要减少美国消费和进口,促进投资和出口。中国与美国之间的贸易失衡被认为是美国经常账户失衡的重要原因,中美贸易的"再平衡"因此成为中美双边贸易谈判中美方的基本诉求之一。然而,尽管中美两国政府在促进中美贸易平衡发展并转变各自经济增长方式方面有一定的共识,但目前中美贸易失衡格局的形成主要原因在于经济全球化条件下的国际分工,两国目前都不可能采取过于激进的政策来强行调整。在国际分工体系发生实质变化之前,中美贸易失衡状态短期内只能寻求缓解而不是消除。

作者： Yilin wang Jianke Cao Yankai Chang Fuchang Yu Sumei Zhang rongjun wang Longxian Zhang

Cryptosporidium *** Giardia duodenalis are common gastrointestinal parasites with a broad range of hosts,including humans,livestock,and *** examine the infection status and assess the zoonotic potential of Cryptosporidium *** *** in dairy cattle in Gansu,China,a total of 1414 fecal samples were collected from the rectum,and one sample was collected from each individual *** the samples were tested using nested PCR based on the small subunit ribosomal RNA(SSU rRNA) gene of Cryptosporidium *** *** overall infection rates of Cryptosporidium *** were 4.2%(n=59) and 1.0%(n=14),*** Cryptosporidium species were identified:***(n=42),***(n=12),***(n=5),and ***(n=1).In further analyses of subtypes of *** isolates based on the 60 kDa glycoprotein(gp60) gene,five were successfully subtyped asⅡdA19 G1(n=4) and IIdA15 G1(n=1).All 14 *** isolates were identified as assemblage E using triosephosphate isomerase(tpi) *** relatively low positive rates of Cryptosporidium *** Giardia duodenalis detected here and the predominance of non-human pathogenic species/assemblages of these parasites indicated their unique transmission dynamics in this area and the low level of threat posed to public ***,continuous monitoring and further study of these parasites should be conducted for the prevention and control of these pathogens.
