stretching force meaning in English
张拉力
张力
Examples
- The elongation of a body in tension above its no-load length is directly proportional to the stretching force .
物体在拉伸状态下，其伸长量（相对于无负荷时的长度）与拉伸力成正比。 - That is to say , the amount of the springback decreases with the increase of the pre - stretch force and lateral compression , and the decreasing trend is close to a linear relation , and when the lateral compression is large enough , the negative springback appears
理论分析和试验均表明：回弹半径随着预拉力和侧压力的增大而减小，减小趋势基本为线性关系，当侧压力足够大时，出现负回弹。 - The formation dynamic mechanisms is very complicated . the uplifting and thickening of crust are the result of various causes . but the main reason is the plate subduction which is the basic cause to have the gravitation , thermo - dome and stretching force become useage
青藏高原处于复杂的动力体制中，陆壳增厚和隆升是各种因素共同制约的结果，但板块俯冲机制是主导的，是使其它力源，如重力、热动力和张力等成为有效驱动力机制的基本因素。 - This article performed an application of such means as modern test technology , computer processing system , serial ports communication and electrohydraulic proportional control technology to reform the sheetmetal combined testing machine , so that the stretching force , clamping force and the stretching length can be tested and controlled by the computer system , which greatly improved the stability and testing precision of the testing machine
摘要通过应用现代测量、微处理、串口通信、电液比例控制等技术，对自行研制的钣金综合试验机进行了改造，实现了对拉伸力、夹紧压力和拉伸长度的计算机数据采集和控制，大大提高了原系统稳定性和测试精度。 - Self - erection system is applied to construction of most of modern large span concrete bridges . in the process of construction , cantilever beam is changing continuously because of the gravity of concrete , the stretching force , the load and temperature variation etc . in order to ensure that two cantilevers constructing opposite can normally close up and that the bridge linearity can accord with design , flexibility deformation has to be monitored
现代大跨度混凝土桥梁多采用自架设体系施工，在混凝土自重、张拉力、桥面荷载、温度变化等的作用下，悬臂梁体处于不断的变化之中，为保证对向施工的两端悬臂能正常合拢和控制成桥线形符合设计要求，需要对施工过程中的挠度变形进行监测。
