重新认识Windows 95

着手分析Windows 95之前,我心里没有一点底,也不知最后能得到怎样的结果。世界头号独立软件公司;投资数千万美元,数百位软件业界精英,没日没夜,耗时近四年的艰苦开发;发行了不少于三个Beta版及上百个修正软件包;并创造了有史以来规模空前的、号称400000多人参加的广泛测试,Windows 95理应炼就了“金刚不坏之身”,这难道还需怀疑吗?

Screening efficiency and screen length of a linear vibrating screen using DEM 3D simulation

The effect of screen length on the screening efficiency of particles is studied under various single parameter conditions including frequency, amplitude, vibration angle, and screen inclination. The Discrete Element Method (DEM) has been used to simulate the screening process. A functional relationship between screening efficiency and screen length is established. It is shown that screening efficiency and screen length have a complicated exponential relationship. Relationships between them are profoundly discussed and conclusions are easily drawn: low values of the parameters do not benefit screening; screening efficiency generally increases with screen length; screening efficiency reaches a plateau when these parameters are in range frequently encountered in practical applications.
