分析和讨论了一种新型角加速度传感器的工作原理与设计方法。该传感器是根据流动电热效应，直接将角加速度信号转换为电信号输出的。和其它形式的角加速度传感器相比，它具有结构简单、成本低、可靠性好、稳定性高等特点。     

A Dynamic Forecasting System with Applications in Production Logistics

Production logistics involve the co-ordination of ac tivities such as production and materials control (PMC), inventory management, p roduct life cycle management, etc. Those activities demand for an accurate forec asting model. However, the conventional methods of making sell and buy decision based on human forecast or conventional moving average and exponential smoothing methods is no longer be sufficient to meet the future need. Furthermore, the un derlying statistics of the market information change ...     

刚体平面运动加速度瞬心的推导

刚体以不为零的角速度作平面运动时,在任一瞬时总可以在刚体上找到加速度为零的一点.这一点称为刚体的瞬时加速度中心.以加速度瞬心为基点研究刚体的平动会更加方便.
