| 1 | Static recrystallization behavior of hot-deformed magnesium alloy AZ31 during isothermal annealing显示文摘The static recrystallization of hot-deformed magnesium alloy AZ31 during isothermal annealing was studied at temperature of 503 K by optical and SEM/EBSD metallographic observation.The grain size change during isothermal annealing is categorized into three regions,i.e.an incubation period for grain growth,rapid grain coarsening,and normal grain growth.The number of fine grains per unit area,however,decreases remarkably even in incubation period.This leads to grain coarsening taking place continuously in the whole period of annealing.In contrast,the deformation texture scarcely changes even after full annealing at high temperatures.It is concluded that the annealing processes operating in hot-deformed magnesium alloy with continuous dynamic recrystallized grain structures can be mainly controlled by grain coarsening without texture change,that is,continuous static recrystallization. | 杨续跃 朱亚坤 H.MIURA T.SAKAI | 2010 | Transactions of Nonferrous Metals Society of China2010，20，7： | 4 |

| 7 | 用动测法预测桩的承载力显示文摘本文介绍一种根据应力波理论预测桩的动承载力的新方法。有关测量桩侧及极端阻力的应用方法及理论根据也分别予以讨论。虽然CASE法和CAFWAP分析法已广泛应用于预测桩的承载力,但并未考虑桩的频率特牲。由于锤击力的频率和桩的反射波频率彼此存在很大的差异,在打桩过程中用CASE法难以预测土的阻力。将桩的响应频率低的同样测量频率用于入射波和反射波,以预测打桩时上的阻力。结果发现,本文所述方法与CAPWAP分析法预测的承载力几乎相等。 | N.Kawabata T.Sakai S.Kondo H.Kanai Y.Kobayashi T.Oki S.Nishimura 林晓玲 | 1992 | 土工基础1992，，A10： | 0 |
| 8 | 根据应力波原理估测灌注桩形状的方法显示文摘本文介绍了根据应力波原理,在小应变条件下估测灌注桩形状方法的理论及使用结果。从桩的振动响应估测桩的形状,必须同时确定波动能量在桩上传播的衰减率以及产生反射波的桩构件的特征比。考察波的衰减特性曲线,以分析桩的振动响应,估测桩的形状。从该法应用于灌注桩的试验结果来看,如果对桩的振动响应,包括桩尖的反应形式仔细地进行分析,桩形估测中桩径误差为10~20%,桩长误差小于10%。 | M.Honma T.Sakai H.Murakumi N.Koyama H.Inagawa T.Miyasaka Y.Tanaka 林晓玲 | 1992 | 土工基础1992，，A10： | 0 |
| 9 | Using LiF crystals for high-performance neutron imaging with micron-scale resolution显示文摘This paper describes an overview of our recent discovery – clear demonstration that Li F crystals can be efficiently used as a high-performance neutron imaging detector based on optically stimulated luminescence of color centers generated by neutron irradiation. It is shown that the neutron images we have obtained are almost free from granular noise, have a spatial resolution of~5.4 μm and a linear response with a dynamic range of at least 103. The high contrast and good sensitivity of Li F crystals allow us to distinguish two holes with less than 2% transmittance difference. We propose to use such detectors in areas where high spatial resolution with high image gradation resolution is needed, including diagnostics of different plasma sources such as laser and z-pinch produced plasmas. | A.Faenov M.Matsubayashi T.Pikuz Y.Fukuda M.Kando R.Yasuda H.Iikura T.Nojima T.Sakai M.Shiozawa R.Kodama Y.Kato | 2015 | High Power Laser Science and Engineering2015，3，4： | 0 |
