envelope diagram meaning in Chinese

包络图

The initial strain must be the optimum value obtained by multiple - trial method . 5 . in the static analysis of the bridge model under live load , assuming a shifting concentrated load on the girder , analyzing the relation map of each section deflection and the location of the concentrated load , finishing the load - on of the worst - case live load , then the moment and deflection envelope diagrams of the girder were obtained
成桥模型建立后，在后续活载作用下的静力分析必须首先在主梁上作用移动集中荷载，分析主梁各断面的活载挠度与集中荷载作用位置关系曲线图，完成最不利活载的加载，从而最后得到悬索桥主梁的弯矩包络图及挠度包络图。
