By use of the continuous conditions between adjoining sections, ge-neral formulas of internal forces and displacements are derived and the prob-lem finally becomes to solve a simultaneous linear equations with two unk-nowns. 然后给出每一小段用初参数表示的解,再利用各段之间的连续条件,给出内力与位移的一般表达式,并最后将问题归结为一个二元一次方程组的求解。
It is a glad tidings for people in Shanghai to discover the natural drinking mi-neral water in the west part of Shanghai. 上海市区西部发现饮用天然矿泉水,这是上海市民的福音。
A general method for finding the Mean first passage time of go neral diffusion processes driven by shot noise is suggested. 本文对散粒噪音驱动的一般扩散过程作了系统分析,为求平均首通时间提出了一个一般化的方法。
The ge neral fatigue theory of rolling bearings is unable to predict the failure due to skidding and skewing of rolling elements, which often occur in high speed roller bearings. 在高速轻载的工况下,滚子轴承的打滑蹭伤及由于滚子歪斜引起的滚子端面磨损已成为滚子轴承的主要失效原因。
