	1	A Tractable Approach to Analyzing the Physical-Layer Security in K-Tier Heterogeneous Cellular Networks显示文摘This study proposes a tractable approach to analyze the physical-layer security in the downlink of a multi-tier heterogeneous cellular network. This method is based on stochastic geometry, has low computational complexity, and uses the two-dimensional Poisson point process to model the locations of K-tier base stations and receivers, including those of legitimate users and eavesdroppers. Then, the achievable secrecy rates for an arbitrary user are determined and the upper and lower bounds of secrecy coverage probability derived on the condition that cross-tier interference is the main contributor to aggregate interference. Finally, our analysis results reveal the innate connections between information-theoretic security and the spatial densities of legitimate and malicious nodes.

	4	In situ Observation of Mo Implanted HI3 Steel by Transmission Electron Microscopy显示文摘In situ observation in high voltage transmission electron microscope(HVEM)was used to investigate the structure of Mo implanted HI3 steel.Instead of tempered Martensite structure,the implanted layer has a fine grain structure.When the implanted specimen is heated inside the HVEM,the fine grain structure does not change until 500℃.The electron diffraction pattern of precipitates FeMo appears at 500℃.Recrystallization and grain growth occur at 650℃.
