精密垫片精冲工艺有限元分析与模具设计

精密垫片零件，如图1所示，零件材料为1Cr18Ni9Ti，强度大（σb=650MPa），有一定塑性。从零件尺寸精度看，φ4mm外圆为IT7级精度，φ4mm外圆与φ2mm内孔有很高的同轴度要求，冲裁断面与零件两端面有垂直度要求，普通冲压不能达到零件精度：从工序的角度看，有冲孔和落料工序，剪切面粗糙度Ra≤3．2μm，属于光洁冲裁范畴；另外，技术条件中要求零件两大面不得有任何划伤，且光滑平整。总体上看，该零件的冲压加工性不好，难度较大，对模具的设计、选材、制造要求都较高。     

养殖池塘沉积物的重金属分布及污染特征

浙江省淅西北地区淡水养殖池塘沉积物重金属调查研究表明，养殖池塘沉积物中7种重金属元素分布不均衡，差异也较大，除Hg和Cr元素外，其余重金属元素已大大超过土壤本底值．虽然其实测含量都未超出国家规定的标准值范围，但沉积物中重金属元素对养殖水环境、养殖品种存在的潜在污染与危害值得关注．污染指数评价显示，养殖池塘沉积物中主要污染物质为Cu和Cr，而Hg、Pb污染程度相对较轻．     

短脉冲激光辐照下金属镜面波纹损伤机理研究

用脉冲Nd：YAG激光(波长1．06μm、半高宽10ns)辐照了多种金属膜层镜面，用光学与原子力显微镜观察到某些样品损伤区或周围有规律的波纹图案，波纹周期从几微米到几十微米。通过分析实验结果，这里提出了波纹产生的光学模型，认为光路系统中某些元件的衍射或者强光与元件表面相互作用过程中产生的干涉可能会导致元件表面波纹状损伤图案。通过理论计算，初步解释了实验中波纹的周期和其他现象。

Transmission Properties of THz Radiation Pulses through Very Deep Zero-Order Metallic Gratings

Very deep zero-order metallic grating structures are processed to study the transmission properties of THz radiation pulses. The experiments have been performed with two samples. The delay of the THz pulses and the corresponding resonantly enhanced transmission spectra through the samples are observed. To explain the extraordinary transmission we have treated the samples as Fabry-Perot resonators through resonant excitation of the coupled surface plasmon polaritons filled in the cavities between the metal slats. The experimental results are in reasonable agreement with the numerical simulation. Our results show that THz-time-domain spectroscopy may be an effective technique for studying the optical properties of various THz microstructured devices.     

Deformation Morphology underneath the Vickers Indent in Bulk Metallic Glasses

Plastic deformation behaviour of Zr52.5Al10Ni10Cu15Be12.5 and Mg65Cu25Gd10 bulk metallic glasses (BMGs) is studied by using the depth-sensing nanoindentation and microindentation. The subsurface plastic deformation zone of the BMGs is investigated using the bonded interface technique. Both the BMGs exhibit the serrated flow depending on the loading rate in the loading process of indentation. Slow indentation rates promote more conspicuous serrations, and rapid indentations suppress the serrated flow. Mg-based BMG shows a much higher critical loading rate for the disappearance of the serration than that in Zr-based BMG. The significant difference in the shear band pattern in the subsurface plastic deformation zone is responsible for the different deformation behaviour between the two BMGs. Increase of the loading rate can lead to the increase of the density of shear bands. However, there is no distinct change in the character of shear bands at the loading rate of as high as1000 nm/s.     

Activation and Afterheat Calculation Analysis for TBM

Safety considerations of TBM are part of the design process to ensure that the TBM do not adversely affect the safety of ITER. So accurate calculations of all radioactivity and potential harmfulness are very important for designing of device, selecting of blanket and shield material, analyzing of the safety and environment, disposing of nuclear waste and operation of the reactor.
