振动能量采集技术是一种非常有前途的清洁能源技术,在飞行器结构传感器网络等方面有重要应用潜景。针对低频振动能量采集技术主要存在的功率密度低、采集频带窄等问题,提了出碰振升频振动能量采集设计方案。在考虑机电耦合的前提下,建立了碰振升频采集系统的碰撞动力学模型,并对其进行了无量纲化处理。通过数值仿真,研究了不同碰撞间隙对系统输出电压和输出功率的影响,探讨了碰撞次数对电能输出改变的规律。研究结果表明:高频采集振子对低频驱动振子起到限位作用;随碰撞间隙的减小,输出电压的均方根峰值往高频方向移动,并不明显影响最大的输出电压;在碰撞发生频带,高频采集振子对总功率输出的贡献比例明显提升,约提升30%;相较于多次碰撞而言,单次碰撞更能确保电能输出的稳定性。

The electronic structure, atomic geometry and energetic properties of ceramic nanomultilayer have been systematically studied with first principles density functional theory calculations based on the generalized gradient approximations. It is found that the interface structure and adhesion, which determine the mechanical and thermal properties, are sensitive to the surface mor- phology. We also provide an analysis of adhesion of ZrO2/A1203 interface as a function of thickness of each layer. With the in- crease of ZrO2 thickness, both covalence and ionicity of the interfacial bonds are enhanced, which results in more strongly coupled interfaces while the ionic interaction decreases for thicker Al2O3 layers, which results in weakly coupled interfaces. A first-principles calculation method has been proposed to design nanomultilayer materials to achieve the demanded adhesion.

＜正＞This paper considers a simple model for hard-decision parallel interference cancellation in a code-division multiple-access（CDMA） system. Because practical systems will experience timing errors,the effect of timing errors need to be analyzed. Previous work in this area has relied heavily on simulation *** analyzing statistical characteristics of residual multiple access interference, we obtained a analytical expression for the probability of bit error in hard-decision parallel interference cancellation with timing *** results are shown to agree well with simulation.

This study evaluates the performance of the regional climate model RegCM4 in simulating tropical cyclone(TC) activities over the Western North Pacific(WNP) and their landfalling in China. The model is driven by ERA-Interim boundary conditions at a grid spacing of 25 km, with the simulation period as 1991-2010. Results show that RegCM4 performs well in capturing the main structural features of observed TCs, and in simulating the genesis number and annual cycle of the genesis. The model reproduces the general pattern of the observed TC tracks and occurrence frequency. However, significant underestimation of the occurrence frequency as well as the TC intensity is found. Number of the landfalling TCs over China is also much smaller than that of the observed. Bias of the model in reproducing the large-scale circulation pattern and steering flow may contribute to the underestimated landfalling TC numbers.
