查询词典 variable condenser

Based on the flaw of the probability reliability model in the case of small amount of information,non-probability and mixed probability/non-probability reliability models are presented. When the uncertainty of the basic random variable is described by convex, analytical and numerical methods are constructed to calculate the convex of response variable. The infinite norm index, which is the minimal infinite norm distance from original coordinate point to the surface of the limit state in the standard interval space, is presented to measure the safety of the structure.

针对概率可靠性模型在小子样信息下的缺陷，建立了非概率可靠性模型及概率—非概率混合可靠性模型；给出了用集合来描述变量不确定性时，极限状态变量变化集合的解析解和数值迭代解法；提出了物理概念明确且十分易于工程应用的度量结构、机构安全程度的无穷范数指标，它是标准区间空间中坐标原点到极限状态表面的最小无穷范数距离。

To resolve this problem, we'll reel outwards drive across the bridge to the intermediate surface of variable-speed drive wheel with two wheels of processed into 30 °, the increase in friction with Groove, even if such a belt would not have had; the diameter of 6 mm, spin out to o-rubber belt changed out with Burr corn-cob o-shaped belt; crossing the bridge to another variable-speed drive belt pulley to roll out of the book, two rounds of the belt pulley turned into 1/2 inch, using chain drive sprocket, and fixed machinewe side wall to cross the bridge wheel seat side wall plate processing growth holes for adjust tension pulley and sprockets.

为解决这个问题，我们将分切机朝外传动面传动到中间过桥变速皮带轮的两轮加工成30°的带槽，增加摩擦力，这样皮带即使松了也不会打滑；直径6mm的O型橡胶皮带改成外面带毛刺的聚氨酯O型皮带；过桥变速皮带轮的另一个传动到出书辊的皮带轮，两轮改成1/2英寸的链轮，采用链条传动，再将固定在机器侧墙板的过桥轮座侧墙板孔加工成长孔，可任意调整皮带轮与链轮的松紧。

This paper makes further research on the error,caused by use of a single step or a variable step of Runge Kutta to solve the Euler equation of quaternion method, find that the large error results from cumulated error with single step, and when using the variable step,the cumulative error is less.
