Fe－Cu包埋团簇的制备及其微观结构的研究

基于溅射－气体－聚集（ＳＧＡ）形成团簇的原理，提出了蒸发－气体－聚集（ＥＧＡ）共沉积方法，并在方华膜载网上成功地制备了Ｆｅ－Ｃｕ纳米磁性包理团簇样品。ＴＥＭ／ＥＤ分析表明，样品中Ｆｅ团簇被Ｃｕ原子所包裹，形成了以Ｆｅ团簇为芯，Ｃｕ膜为壳的良好的芯－壳式包埋结构。当衬底温度由２５℃变化到２００℃时，样品形貌由弥散状过渡到集团状，直至形成大的块状；其结构也相应的由Ｆｅ－Ｃｕ多晶共存变化为一种不规则的单晶形态。

Characteristics of aperture coupled microstrip antennas withvarious radiating patches and coupling apertures

A full wave moment method is applied to the analysis of aperture coupled microstrip antennas, in which all components of the electric and equivalent magnetic surface currents are considered. The electric current distributions on the rectangular patch for different coupling aperture positions are presented with their radiation patterns. The effects of the coupling aperture shape and size on the input impedance and radiation performance are also discussed. As an example of new radiators, slotted patches are studied, and it is shown that they can be used to achieve dual-frequency operation

The effects of plasma etching induced gate oxide degradation onMOSFET's 1/f noise

The effects of the plasma etching process induced gate oxide damages on device's low frequency noise behavior are investigated on MOSFET's fabricated with different field plate perimeter to gate area ratio antennas. Abnormal 1/f noise spectrum with a shoulder centered in the frequency range of 100 and to 1 kHz was frequently observed in small geometry devices, and it is attributable to a nonuniform distribution of oxide traps induced by plasma etching process     

Construction and utilization of rock caverns in Singapore Part D: Two proposed cavern schemes

This paper considers cavern schemes for crude oil storage and warehouse-shelter facilities. The crude oil storage scheme, which consists of five caverns, provides a net storage capacity for crude oil of 800,000 m³; the total cost for the facility, including civil construction, mechanical and electrical instrumentation, is in the order of S$80–100 million. The warehouse-shelter scheme consists of five storage caverns with combined storage capacity of 210,000 m³, and a defence shelter with capacity of 2000 persons. The cost for the warehouse-shelter scheme is S$66 million, including all mechanical and electrical utilities, systems for ventilation, fire prevention and smoke extraction, and pump installations for discharging leakage water.
