1对比增强超声显示的颈动脉斑块新生血管与临床症状的相关性显示文摘目的采用微气泡对比剂.评价颈动脉粥样硬化病人斑块的强化程度与临床症状的相关性。方法本研究得到医院伦理委员会批准,所有病人均签署知情同意书。104例颈动脉粥样斑块的病人[男性83例,平均年龄(64±9)岁;女件21例,平均年龄(61-10)岁]行普通超声和对比增强超声检查。采用视觉和定量分析评价斑块的强化程度。结果在104例病人中,35例(34%)有一过性缺血发作和(或)脑血管缺血性卒中。35例有症状和69例无症状的病人中,分别有28例(80%)和21例(30%)病人可见斑块强化(P〈0.001)。L.

2从沉积物特征谈太湖的演变显示文摘通过太湖湖底淤泥层中的微体古生物及其物理化学分析,在西太潮W1孔发现多门类海相化石。海相化石出现的时间约在1100—5000aB.P.之间。据此提出西太湖在全新世期间曾遭受海侵,因而支持了太湖形成于泻湖的说法,同时,还提出海水进入太湖的时间,比以往学者推测的早2000多年。William Y.B. Chang 许雪珉 杨景荣 刘金陵 1994湖泊科学1994,6,3:14
3THEORETICAL INVESTIGATION ON BY-ONLY-CURRENT ELECTROMAGNETIC SEPARATION OF INCLUSION FROM MOLTEN METALS显示文摘The electromagnetic field under applied AC and DC current in round and rectangularpipe was systematically investigated, then a concept of 'equivalent current density'was proposed for evaluating the inhomogeneous electromagnetic pinch force, and themono-component removal efficiency and the overall removal efficiency of inclusionwere formulated. It is founded that flat pipe is superior to round pipe for the electro-magnetic removal of inclusion, and DC current can get a higher removal efficiencythan AC current due to absence of skin phenomenon. Under usual condition, a re-moval efficiency of 52% for 10μm inclusion or more than 92% for 20μm inclusioncan be achieved by imposing a current density of 3× 106A/m2 in a fiat pipe.B. W. Zhang, Z.M.

5THE COMPUTATION AND EXPERIMENT ANALYSIS OF ELECTROMAGNETIC CONTINUOUS CASTING WITH SOFT-CONTACTED MOULD显示文摘In this paper, coupling the quasi-3D numerical simulation of electromagnetic field and the experiments of continuous casting with soft-contacted mould with some metals such as tin, aluminum, copper and steel, the electromagnetic characteristics of continuous casting with soft-contacted mould is analyzed. It is shown that the electromagnetic pressure on the surface of billet is increasing with the rising of power frequency as a logarithmically parabolic function, with that of electric conductivity of billet as a power junction, and with that of the current in inductor as a parabolic junction.K.
