direct stress meaning in Chinese

法向应力
正交应力
正应力
直接应力

A simple normal or direct stress produces a certain elongation or contraction of the material .
单纯的正应力使材料产生一定的伸长或缩短。

The results of spatial analysis and planar analysis were finely compared with the measured value . by comparison , some conclusions are obtained : model ' s errors are in evidence , when using planar model to analyze the cable - stayed bridge in building , especially for girder ' s distortion ; the transverse distributing of direct stress along axis of bridge is apparent ; and the method of planar analysis ca n ' t satisfactorily solve asymmetry of stress ' s transverse distributing
空间分析结果、平面分析结果与实测结果这三者的比较表明：在pc斜拉桥施工控制中，用平面杆系理论进行结构分析存在一定的模型误差，尤其在主梁的变形分析上；纵桥向正应力沿横向分布的不均匀性明显，用平面杆系理论没法很好地考虑此效应。
