| 1 | 低温金属环境中^198Au半衰期的测量显示文摘利用德国鲁尔大学DTL实验室的中子源,通过197Au(n,γ)198Au反应得到198Au@Au样品,在室温(T=293 K)和低温(T=12 K)条件下交替测量金属Au环境中198Au的412 keV特征γ射线,通过分析得到不同温度下198Au的半衰期。实验结果表明,与文献值T1/2=(2.694 3±0.000 8)d相比,T=293 K时198Au的半衰期变长(0.4±0.7)%;T=12 K时变长(4.0±0.7)%。这一变化趋向与德拜等离子体模型的预言相符,但其幅度显著小于模型的估计值。 | 曾晟 T.

| 2 | EFFECT OF THE CONTROLLED ROLLING CONTROLLED COOLING ON STRENGTH AND DUCTILITY OF THE BAINITE MICRO ALLOYED ENGINEERING STEEL显示文摘The continuous cooling transformation of hot deformation austenite austenite of test steel and the effect of different processing schedules of controlled rolling and controlled cooling on the strength and ductility have been studied. The theory and the experiment base are presented for controlled rolling and controlled cooling of the SBL micro alloyed engineering steel. | Z. Li, G. D. Wang,X. H. Liu and C. Y.

| 3 | EFFECT OF HOT DEFORMATION PARAMETERS ON RECRYSTALLIZATION OF STEEL T91显示文摘In this paper, the recrystallization behavior of steel 9Gr- 1Mo - V-Wb - N at high temperature was studied using Gleeble - 1500 thermalmechanical simulator.The critical conditions of occurrence of dy- namic recrystallization during hot deformation were obtained,and by means of double hit testing with an inter -hit time, the metabynamic recrystallization between rolling passes and its effect factors were also imitated.Additionally,the deformation activation energy of T91 steel,the relationship between critical stress,strain, temperature, and strain rate were regressed respectively, the results were sati- sfied. | F.

| 6 | 极低出生体重婴儿脐动脉导管血液采集量和速度对脑血容量和氧合度的影响显示文摘Aim:Blood sampling from umbilical artery catheters decreases cerebral blood volume and cerebral oxygenation.The aim of this study was to assess the impact of sampling volume and velocity.Methods:Forty-eight infants,median birthweight 965 g(480-1500 g),median gestational age 27 wk(23-34 wk),were studied during routine blood sampling from umbilical artery catheters.The sampling procedure was performed following a strict protocol for draw-up volume(1.6 ml),sampling volume(1.7 ml or 0.2 ml),re-injection volume(1.6 ml)and flushing volume(0.6 ml),time of aspiration(40 s or 80 s),reinjection(30 s)and flushing(6 s).In each infant,sampling volume and aspiration time were subject to sequential variation in a randomized fashion(1.7 ml/40 s,1.7 ml/80 s,0.2 ml/30 s).Using near-infrared spectroscopy,changes in concentrations of cerebral oxygenated and deoxygenated haemoglobin were measured,and changes in cerebral blood volume and cerebral oxygenation were calculated.Results:During all three sampling procedures,oxygenated haemoglobin decreased significantly from baseline,whereas deoxygenated haemoglobin did not change.Correspondingly,a decrease in cerebral blood volume and cerebral oxygenation occurred.This decrease was not affected significantly by extending the sampling time from 40 s to 80 s,whereas it was blunted by reducing the amount of blood withdrawn.Conclusion:Blood sampling from umbilical artery catheters induces a decrease in cerebral blood volume and cerebral oxygenation.The magnitude of the decrease depends on the blood volume withdrawn but not on sampling velocity. | Roll C.

| 7 | 早产儿脑萎缩的超声诊断结果与神经发育结果相关显示文摘Abstract Abstract Background: Intraventricular haemorrhage and periventricular leukomalacia are associated with poor outcome of very preterm infants, while the role of more subtle cerebral alterations, as detected by cranial ultrasound, is less clear. Aim: In this study, we related periventricular echodensities and signs of brain atrophy to neurodevelopmental outcome at 3 y of age. Patients and methods: All preterm infants born in 1997 in our institution with a gestational age < 32 wk or birthweight < 1500 g were subjected to repeated standardized cranial ultrasound examinations until discharge. Survivors were examined at 3 y of age employing the Bayley Scales of Infant Development II. Results: Eighty-seven infants were enrolled (birthweight 430-2500 g (median 1200 g), gestational age 24-34 wk (median 29 wk)). Periventricular echodensities were detected in 42 infants (48%); in 12 cases persisting < 7 d, in 30 cases > 7 d. At discharge, 18 infants (22%) had signs of brain atrophy. Neurodevelopmental outcome was assessed in 64 infants. Infants with signs of brain atrophy scored significantly lower on MDI (atrophy 91.8, no atrophy 101.9; P = 0.02), PDI (atrophy 91.4, no atrophy 106.5; P = 0.001) and Behaviour Rating Scale (atrophy 41.1, no atrophy 66.4; P = 0.01) than infants without atrophy. Periventricular echodensities were not related to outcome. Conclusion: Our data show that infants with sonographic signs of brain atrophy at discharge achieve lower scores in neurodevelopmental testing at 3 y. | Horsch S. Muentjes C. Franz A.

| 8 | COMPUTER AIDED ANALYSIS FOR COLD ROLL FORMING THIN CHANNEL SECTION显示文摘Cold roll forming is a complicated metal processing, and it is very difficult to simulate the forming process. Based on the Updated-Lagrange method in the deformation me chanics, an elastic-plastic large deformation spline finite strip method is developed to analyze cold roll forming of a thin channel section. The longitudinal membrane strain values on the edge of the deformed strip for four one-pass sequences in different fold angles are got. Simulated restults are compared with the results from previously conducted experiments. The deviation of the simulated peak strain values is within 30% compared with the experimental results. | Z. W.
