变力作用 meaning in English
inotropic action
Examples
- We conclude this section with two examples of motion under the action of a variable force .
下面我们举两个关于物体在变力作用下运动的例子来结束这一节。 - By analysis and compare to continuous rigid frame bridge at the condition of temperature uniform change , i found the bending moment change of pier either single pier or thin double piers takes a increasing trend with the ratio of beam bending rigidity and pier lateral displacement rigidity . the bending moment has a extreme value when the ratio of rigidity very small ( a constant ) . and in the condition , the structure inner force changes in the pier which mainly takes bending at first and takes bending and shearing force at last
通过分析比较，发现连续刚构体系桥梁在受到均匀温变力作用下：无论是单墩还是双薄壁墩结构的弯矩都随梁的抗弯刚度与墩抗侧移刚度比的降低而呈增长趋势，当刚度比值小到一定值时弯矩将出现极值，随着刚度比进一步的减小弯矩值又将呈下降趋势，而结构由最初的墩以弯曲内力为主逐步转向以弯剪共同作用；结构的剪力值随梁抗弯刚度与墩抗侧移刚度比的降低而呈单向攀升趋势，其增长速率较快。
